Gluten-Free Flour Guide and Simple Substitution Reference

The world of gluten-free baking is both wonderful and challenging – the results can be incredibly delicious, but it can take some trial and error to discover the best gluten-free flour combinations and which flours to use and when. In the Culinary Nutrition Expert Program, which is entirely gluten-free, we have an entire module dedicated to gluten-free baking and sweet treats! In other words, gluten-free flours are important to culinary nutrition!

We’ve spent many years experimenting with both sweet and savory gluten-free baked goods (a tough job, we know) and have learned a lot along the way. Using this A to Z gluten-free flour guide, you can skip the flops and rock-hard gluten-free muffins and go straight to the scrumptiousness.

The most important thing to know about working with gluten-free flour options is this: you must blend multiple flours together for the best results. Using a singular gluten-free flour will result in those hockey puck cookies that no one wants to eat. So generally, when you are substituting a gluten-free flour for a wheat flour, or a gluten-free flour for another gluten-free flour, you’ll need to play around a bit and see what works best for you.

Without further ado, here are some of our well-loved gluten-free flour options and the best way to use them.

Almond Flour

Grain-Free Almond Chocolate Chip Cookies

What is it?

Take raw, blanched almonds, grind them to a fine flour and you have almond flour. You can also buy milled almond flour, which is finer in texture, or save your almond pulp and blend it up into almond flour. This and other nut flours — such as hazelnut, walnut, pecan and seed flours — add protein, fibre and vibrant taste to grain-free and gluten-free baking.

Best for: Cookies, cakes, muffins, hearty crusts, pancakes, crumble toppings. Heavily used in Paleo diet recipes.

How to substitute: Use up to 25% of nut flours in gluten-free flour mixes.

Amaranth Flour

What is it? 

The tiny whole grains that make a surprising breakfast cereal can also be ground into a fine flour. Amaranth is rich in protein and has a grassy, earthy taste.

Best for: Due its grassy flavour, use it in savory dishes like pizza dough.

How to substitute: Swap it 1:1 from glutenous flour

Arrowroot Flour

Grain-Free Sandwich Cookies

What is it?

Arrowroot flour is a fine flour that comes from the arrowroot plant (you may also see it labelled as arrowroot starch or arrowroot powder). It looks very similar to corn starch, potato starch and tapioca starch.

Best for: Use it as a thickener in place or corn, potato or tapioca starch. It’s also helpful when you need any kind of dough to stick together.

How to substitute: Substitute arrowroot flour 1:1 in place of corn, potato or tapioca starch. When using it in baking, aim to have no more than 20% arrowroot in your gluten-free flour mix.

Bean Flours

What is it? 

Dried beans can be ground into flours as easily as grains can.  Chickpea flour — also known as garbanzo bean or ceci flour — is used for flatbread in the south of France. Lentil flour shows up in Indian cuisine. Fava beans become flour and show up in some commercial gluten-free baking mixes. They are all rich in protein and fibre.

Best for: You can use bean flours in both sweet and savory dishes, but use them in small doses as their flavour can be overpowering.

How to substitute: Use up to 25% of bean flours in gluten-free flour mixes.

Buckwheat Flour

What is it?

Buckwheat flour is made from ground buckwheat. Has a rich, nutty flavour and a very high nutritional value, making it popular in many nations, especially in Asia. Buckwheat is the fruit of the buckwheat plant and has no relation to wheat or grasses – so it is a 100% gluten-free flour.

Best for: Muffins, cookies, pancakes, waffles and breads

How to substitute: Add up to 50% of buckwheat flour in your gluten-free flour mixes

Recipe to Try: Healthy Buckwheat Crepes

Coconut Flour

Mini Gluten-Free Apple Galette

What is it?

This gluten-free flour is made from coconut that’s been dried and ground. It’s very dense, high in protein and it’s the most fibrous of all of the flours. That’s why you’ll need to add at least an extra 1/4 cup of liquid to your recipes when using it. It’s commonly used in Paleo diet recipes and pairs best with eggs – so it doesn’t always work in vegan recipes.

Best for: Things that don’t need to rise very much like pancakes, cookies, waffles and crusts

How to substitute: Coconut flour soaks up a lot of liquid, so use 1/4 cup of coconut flour in place of 1 cup glutenous flour (or another gluten-free flour). You’ll also need to add an extra 1/4 cup of liquid.

Recipe to Try: Mini Gluten-Free Apple Galettes

Millet Flour

What is it?

Mild and ever-so-slightly sweet, millet is an adaptable grain that is rich in magnesium, nature’s relaxant mineral. It soaks up the tastes of the foods surrounding it, making it a very neutral gluten-free flour to use. Millet flour lends a crumbly texture to breads and muffins and is the least allergenic of all the grains.

Best for: Breads, muffins, cookies, cakes, crusts

How to substitute: Use up to 25% of millet flour in your gluten-free flour mixes

Oat Flour

What is it?

Oat flour is simply made by grinding whole grain oats in the food processor or blender. It’s rich in soluble fibre and it’s great for balancing blood sugar levels. One thing you need to ensure if using oat flour is that it’s 100% gluten-free. While oats are naturally gluten-free, they are often planted and processed alongside wheat, leading to cross contamination. Buy certified gluten-free oats for grinding into flour, or certified gluten-free oat flour.

Best for: Breads, muffins, cookies, cakes, crusts, granola, fruit crisps, scones

How to substitute: Use up to 20% of oat flour in your gluten-free flour mixes

Recipe to Try: Chocolate Cherry Chia Bread

Quinoa Flour

What is it? 

As a grain, quinoa is nutty and delicious. As a flour, quinoa is a little bitter. It’s packed with protein, but the texture adds density to gluten-free baked goods. Use a little quinoa flour in combination with other gluten-free flours for the added protein boost without the bitterness. You can also toast your flour in the oven to amp up the flavour.

Best for: Savory baked goods like biscuits, flatbreads, zucchini bread or herbed muffins

How to substitute: Due to its high protein content, you can use this 1:1 for wheat flour, but we recommend only using up to 25% in baking mixes.

Recipe to Try: Herbed Quinoa Flatbread

Rice Flour

Yummy Pancakes by Tammie Duggar

What is it?

When farmers harvest rice, they shuck the grains of its outer husk, which are inedible. What is left after this process is brown rice. If the farmer also removes the germ and bran from the rice grain, he or she is left with white rice. Brown rice flour is made from the first type of rice, and white rice flour is produced from the latter. Whether it is brown or white, each type can be ground into rice flour. This is a great base for gluten-free baking.

Best for: All kinds of gluten-free baking. Can also be used as a thickener in soups, stews, fillings, etc.

How to substitute: Swap it 1:1 for glutenous flour or any other gluten-free flour. Use up to half of brown rice flour in gluten-free flour mixes.

Sorghum Flour

Vegan Squash + Lentil Muffins

What is it?

Sorghum flour is closest in texture and taste to traditional wheat flour of any of the gluten-free flours. In a few cases, it works as a direct substitution for wheat flour, such as in pancakes. It’s also high in antioxidants.

Best for: Muffins, breads, pancakes, crepes, cookies

How to substitute: Swap it 1:1 for glutenous flour or any other gluten-free flour. Use up to half of sorghum flour in gluten-free flour mixes.

Recipe to Try: Butternut Squash + Lentil Muffins

Tapioca Flour

What is it?

What we in the West call tapioca comes from a plant originally from Asia known as cassava (in South America, it is known as manioc).When the root has been dried, it is ground into white flour. Tapioca flour is also known as tapioca starch. Its starchiness makes it an excellent gluten-free flour, but it must be used in combination with other flours to make great baked goods.

Best for: Mixing into gluten-free flour blends. Can also be used as a thickener in soups, stews and fillings.

How to substitute: Substitute tapioca flour 1:1 in place of corn or potato starch. When using it in baking, aim to have no more than 20% in your gluten-free flour mix.

Teff Flour

What is it?

The tiny seeds of teff make a fascinating porridge. Dark brown as molasses, with a slight taste of chocolate, teff porridge will fill you up in the mornings.  As a flour, teff is nearly miraculous. The fine flour — ground from the tiny seeds — almost dissolves in baking, giving it a slightly gelatinous quality. It binds the baked goods in a somewhat similar fashion to gluten.

Best for: Waffles, banana bread, cookies, muffins

How to substitute: Substitute 1:1 for other gluten-free flours. When making a flatbread like injera, you can use 100% teff. Other times, you may want to use up to 25% teff in your gluten-free flour mixes.

Recipe to Try: Ethiopian Injera

Xanthan Gum and Guar Gum

What is it?

Xanthan gum is used in gluten-free baked goods, toothpaste, salad dressings and frozen foods as a stabilizer. It binds everything together in a uniform consistency. Only a tiny amount (1/2 teaspoon or less) is enough to bind the dough to make cookies and pie crusts.

Guar gum is made from dried and ground seeds of the guar plant, which grows in India and Pakistan. It’s often found in many processed foods such as commercial ice creams and puddings. In small amounts, guar gum can be a somewhat effective binder, mimicking some of the effects of gluten.

Best for:  Gums have a tendency to irritate the digestive system. These are often best avoided for this reason.

    Great stuff. Please keep up the good work!

  2. Thank you for producing this guide. For those people who need to be corn free, seed free, nightshade free, and are reactive to gluten free oat flour, teff, and millet, do you have any other suggestions for gluten-free baking without the use of gums/emulsifiers and potato or corn starches, in influencing texture, such as how long and at what temperatures to allow a gluten-free dough to rest or “prove”? Other than adding a gum, is there any known food science trick that allows any of these flours to rise above the level of a flatbread or pancake?

    1. Academy of Culinary Nutrition

      Great questions! We are not fans of the gums (guar, xantham, etc.) so we just leave them out. To get gluten-free baked goods to bind, we use chia eggs, flax eggs or psyllium husk.

      To get baked goods to rise, baking powder will do the trick for muffins, breads, etc. and it’s possible to find corn-free baking powder. If yeast isn’t an issue/sensitivity, you can use yeast for rising too. When using yeast, you’ll often need to cover the mixture and let it rise in a warm place for anywhere from 30 minutes to 2 hours or more, depending on the recipe.

      Have fun and enjoy gluten-free baking!

  3. Vikki

    Great infographic.

  4. Carol Coutts-Siepka

    Love this! I’m wondering how cassava flour (not tapioca flour) and tiger nut flour would look against some of these other options.

    1. Academy of Culinary Nutrition

      Those two flours are definitely becoming more popular, especially as a part of the Autoimmune Protocol Diet (AIP). You might find these links helpful: and They’re both good options for people who are grain-free and nut-free, though they can be expensive and hard to find in some cities. Good luck experimenting with them!

  5. Devonviolet

    I was glad to find your article about gluten free substitutions. I have been using many of these, however was not sure of what percentages to substitute. So, this was very helpful.

    In addition to being sensitive to wheat (not gluten), I am also senstitive to potato starch (all night-shades) and rice. I pretty much had figured out how to substitute for the potato flour/starch. However, I am totally stumped on how to replace rice flour/starch in my gluten free baking. Do you have any suggestions?

    1. Academy of Culinary Nutrition

      It depends on what you’re making. You could try sorghum, millet or oat flour to replace rice flour (or a mixture of these). Happy baking!

      1. Devonviolet

        Thanks. :D

  6. Becky

    Suggestion on ratio of substituting oat flour in baked goods. If it’s cookies breads etc are the other dry ingredients the same? I am new to gluten dairy free cooking and feel lost. Thanks for any help.

  7. Academy of Culinary Nutrition

    Hi Becky! We recommend using up to about 20% of oat flour in your gluten-free flour mixes. There are some recipes that use more than that, so it really depends on whether you are following a recipe that has already been tested with oat flour or are experimenting on your own.

  8. Kent

    Can’t do any grains, no dairy, nightshades, eggs. Trying to come up with a bread for toast and sandwiches. Experimenting has been expensive and interesting! Any suggestions?

  9. Academy of Culinary Nutrition

    Hi Kent! Can you have chickpea flour? Socca is a nice bread alternative, there is a link in this post: If you can have nuts and seeds, this recipe has an egg-free option:

  10. D Hamill

    I don’t want emails. I just have a question.
    What gluten free flour can I substitute for flour and how much should I use and should I add anything else to the recipe? My recipe calls for 3 cups all purpose flour. I’d like to use almond flour.

  11. Academy of Culinary Nutrition

    It depends on what kind of recipe you are making (muffins, cake, cookies, bread, pizza crust, etc.). It’s tough to answer this question without knowing what you’re making. The ‘best uses’ categories above will indicate what flours you can use for various purposes and that is a good place to start.

  12. Donny Wangke

    We are from Indonesia, we produce pure 100% cassava flour and those extend food products such as pasta, macaroni, cookies, premix that made from cassava flour as it’s main ingredients.
    It was nice to join your community 😊

  13. Dannette

    I was wondering if you have a favorite blend of flours for GF sourdough bread making. Trying to make sand which bread. Prefer almond/oat/buckwheat/arrowroot, but open. Have tried numerous times in unsuccessful bread

  14. Academy of Culinary Nutrition

    Hi Dannette! Yes, our director Meghan Telpner has a full guide to gluten-free sourdough here: Many people have tried this recipe with success!

  15. Rachna

    Thank you for such a helpful article. I’ve seen lots of recipes for Gluten free cakes and muffins that use oats. Since I can’t eat gluten free oats also, what would be the best replacement for oats in such recipes? Would sorghum flour work instead of oats? Or almond flour?

  16. Academy of Culinary Nutrition

    Hi Rachna! If you need to substitute for oat flour, it depends to some extent on the recipe and if you need a baked good to get a decent rise. But generally, brown rice flour or sorghum flour or almond flour would be good options to try!

  17. Erin May 9, 2021

    Are you referring to weight or volume in the swaps?

  18. Academy of Culinary Nutrition May 11, 2021

    Hi Erin! We’re referring to volume.

  19. Susie June 6, 2021

    Hi Megan, From your experience is it possible to make a bread or tortilla for roll ups using millet and/or chestnut flour and/or small amounts of almond flour? I was relying heavily on Cassava flour but found it does not work for my food sensitivities from Hashi’s. Those are the only flours that are in my diet now. I did find one recipe for chestnut flour bread and I made crêpes which were good. Lentil pasta is quite good for those who need alternatives.
    Many thanks!

  20. Academy of Culinary Nutrition June 8, 2021

    Hi Susie! Millet, almond and chestnut is not a combo we’ve tried for tortillas, but you could experiment and see what happens. The grain-free options can be tricky as many of them use cassava. If you can have tapioca, you could try this recipe:

  21. Abel July 21, 2021

    Hello, Do you have any gluten free flour guide and simple reference guide l for sweet potato flour as well?

  22. Academy of Culinary Nutrition July 22, 2021

    Hi Abel! Sweet potato flour isn’t as common or widely available as some of the flours we mentioned in this post. We’d recommend starting off with subbing in about 25% of sweet potato flour.

    Also, you could look on the label of your bag of sweet potato flour (or get in touch with the company) to see if they’ve provided any suggestions for the best ways to use their product.

  23. Sue August 31, 2021

    Trying reproduce GF cake flour as per packet mix from Australian shop – listed coconut flour, green banana flour, pysllium, flaxseed flour, lupin flakes, tapioca flour KfibreTM (other ingredients included raw sugar, cocoa powder, baking powder & salt – then added water + oil. Do you have anything similar in your flour combo’s?

  24. Academy of Culinary Nutrition September 2, 2021

    Hi Sue! It’s a bit tricky for us to troubleshoot as we haven’t had that particular product. You may need to do some trial and error with those flours listed on the label to see if you can replicate it. Here in North America, things are listed on the label according to the amount in the product from most to least. That could be a starting guide for how much to use of each.

    Based on the flours used, you may be better off finding an existing recipe for a keto chocolate cake, an AIP chocolate cake, or a Paleo/grain-free cake.
