Best Nut-Free Substitutes for Almond Flour

Almond flour shows up in gluten-free, keto, and paleo recipes — a problem for nut allergies. The right swap depends on whether the recipe needs almond flour's fat (keto) or just its bulk.

The substitutes, with ratios

Sunflower seed flour (1:1)

Best for: Keto and paleo bakes, macarons

Grind seeds in a food processor; same fat profile. Green-tint quirk with baking soda — add lemon.

Oat flour (1:1 by volume)

Best for: Cookies and quick breads (not keto)

Certified GF if needed.

1:1 GF blend + 1 tbsp oil per cup (as noted)

Best for: Converting almond-flour recipes to pantry staples

Watch out

Coconut flour is NOT a swap for almond flour — it absorbs 3–4× the liquid. Recipes must be redesigned around it, not converted cup-for-cup.

Frequently asked questions

Can I make macarons without almond flour?

Yes — finely ground sunflower seed flour, sifted twice, is the standard nut-free macaron base. Expect a slightly deeper color and add a squeeze of lemon to avoid a green tint.
