Coconut Flour vs Flaxseed Flour: The Ultimate Verdict

Coconut flour and flaxseed flour (also known as flaxseed meal) are both wholesome alternative flours that have plenty of benefits for both health and baking. But – they have many different qualities that make them more suitable for certain types of baked goods. We’re about to do a deep dive into coconut flour vs flaxseed flour – their makeup, nutrition facts, and how they fare when it comes to baking!

Comparing coconut flour vs flaxseed flour

	Coconut Flour	Flaxseed Flour	All-Purpose Flour
Substitution ratio vs all-purpose flour	1:4	1:1*	N/A
Gluten-free?	Yes	Yes	No
Keto-friendly?	Somewhat	Yes	No
Paleo-friendly?	Yes	Debatable	No
Allergens	Coconut (tree nuts)	Flaxseed	Wheat, gluten
Liquid absorbency	High	High	Medium
Pantry shelf life (unopened/sealed)	Up to 2 years	3 – 6 months	6 – 8 months
Best for baking…	Most desserts – especially cakes, cookies, pie crusts, muffins, dense breads (especially pumpkin bread!)	Cookies, pancakes, muffins, cakes (especially low-fat and vegan)	Non-yeast recipes (think cookies, biscuits, and some breads)

*Flaxseed flour can substitute for all-purpose flour 1:1 only in small amounts (think a quarter of the recipe or less). 

Flaxseed flour is a gluten-free and keto-friendly substitute that can be directly substituted for regular all-purpose flour. It’s also known to hold onto moisture for dear life, making it a fantastic option for denser goods. Like chickpea flour, it has a thicker grain size and a greasier texture.

Coconut flour has many of the same base qualities as flaxseed flour, being gluten-, keto-, and paleo-friendly to suit a variety of delicious recipes. It soaks up liquid like a sponge too!

As neither can be used as a 1:1 substitute for all-purpose flour for an entire recipe, they might not be easy to use for beginners and will require a lot of care during the baking process. It’s easier to follow recipes MADE for these flours, like these 30 for coconut flour.

Differences between coconut flour and flaxseed flour

You’ll learn about plenty of differences between coconut flour and flaxseed flour, including the way they bake and their nutritional content, that we’ll go through in this section.

Baking with coconut flour vs baking with flaxseed flour

The biggest differences between the two flours are how they affect your bake. Because it can act as a thickening agent, flaxseed flour is often used as a sub for eggs, oil, and butter. That’s great news for vegans or vegan bakers, or those who just want to cut down on fat content in their delicious treats. 

However, note that they can make baked goods a little chewier and occasionally a little dry so keep that in mind when deciding how much liquid to add. Coconut flour is also super absorbent, just like flaxseed flour, making your goodies prone to dryness – so this is something they both have in common.

A little goes a long way when it comes to both flours!

Ingredients in coconut flour vs flaxseed flour

The best coconut flour and flaxseed flour will each be only made of one ingredient: coconut meat for coconut flour and flax seeds for flaxseed flour (or meal). Both ingredients are ground or milled into a fine powder that retains the nutrients and qualities of the original substance.

Coconut flour + flaxseed flour nutritional facts

Per ¼ cup serving	Coconut flour	Flaxseed flour	All-purpose flour
Calories	120	140	110
Carbs	18 g	8 g	23 g
Fiber	10 g	6 g	1 g
Fat	3 g	9 g	0 g
Protein	6 g	6 g	4 g
Glycemic index score	45	0-35*	85

*The data is spotty for glycemic indexes in general and flaxseed flour in particular. Regardless of the actual number, it’s likely to be low because of flaxseed flour’s low carb content (with most of that being fiber).

Although flaxseed flour is slightly higher in calories than coconut flour, it boasts a low carb content (8g vs coconut flour’s 18g), equal protein content (6g each), and a lower glycemic index score! Each ¼ cup does have 9g of fat, but we’re talking healthy polyunsaturated fatty acids – omega-6 fatty acids and omega-3 fatty acids.

On the other hand, coconut flour is low in fat and high in fiber, making it perfect for those looking for a fiber boost in grain-free desserts. While both are keto-friendly, flaxseed flour is the better option for keto diets (see more low-carb, high-protein flours). 

Overall though, their basic nutritional content isn’t vastly different.

Coconut flour vs flaxseed flour storage

Coconut flour takes the crown when it comes to shelf life, no question. Since it can last up to 2 years unopened in the pantry and flaxseed flour only lasts 3 – 6 months, coconut flour is the better long-term option.

Coconut flour vs flaxseed flour: The ultimate verdict

So, what’s the verdict?

Both flours are fantastic for any bake, but each presents its own special qualities. While coconut has a natural sweetness and flax meal has a pleasant nutty flavor – they also have a lot of similarities when it comes to how they act during the baking process. They’re both perfect for denser bakes and are highly absorbent, making them suitable for pancakes, certain breads, loaves, and more.

As coconut flour has greater shelf stability, a delicious flavor, and is a little more beginner-friendly and commonly found than flaxseed meal, coconut flour is my preferred gluten-free baking flour (check out our favorite brands). But, I should mention again that flaxseed meal can be great for its low glycemic index and low carb content.
