Peanut flour substitutes

Commercially the same defatted peanut flour, usually with a little sugar and salt added.

Best for

smoothies, protein bars, cookies, satay sauce, frostings

This is the closest possible swap because it is essentially the same ingredient. The only adjustment is seasoning: most brands include a small amount of sugar and salt, so a batch of cookies made with it comes out slightly sweeter and better seasoned. Reduce the recipe's salt by a pinch per half cup and its sweetener by a teaspoon or two. Look for an unsweetened brand and no adjustment is needed at all.

The default low-carb flour, richer and much less absorbent.

Best for

cakes and muffins, cookies, pancakes, crusts

The big change is fat and thirst. Almond flour carries around half its weight in oil where defatted peanut flour carries almost none, so the same weight makes a looser batter and a richer, more tender, moister crumb that browns sooner. Hold back two to three tablespoons of liquid per cup and drop the oven 25F. Flavor-wise you lose the roasted peanut character entirely and get a mild marzipan sweetness instead. Not suitable if the peanut flour was there because of a tree nut allergy.

Ground sunflower seeds, the standard nut-free stand-in for any nut flour.

Best for

nut-free baking, school-safe snacks, breads, cookies

Similar protein and similar thirst, so it behaves well in the recipe. What changes is flavor: toasted, faintly bitter and clearly seedy rather than sweet and peanutty, which suits savory bakes and needs a little extra sweetener in a cookie. One quirk to know about: sunflower seeds react with baking soda and can turn a bake green or blue-green. Use baking powder instead, or add a teaspoon of lemon juice to the batter.

Ground, usually partly defatted sesame seeds, high in protein and equally absorbent.

Best for

nut-free low-carb breads, crackers, savory bakes, halva-style sweets

Structurally the closest nut-free match, since like peanut flour it is high protein, low fat and drinks up liquid. The flavor is stronger and more divisive: bitter, toasted and unmistakably tahini-like, which is superb in a cracker or a savory loaf and can taste medicinal in a vanilla cake. Balance it with a little honey, cinnamon or extra salt. Note that sesame is itself a major allergen, so it is only a solution for peanut and tree nut avoidance.

Ground dried chickpeas, similar in protein and absorbency and cheap everywhere.

Best for

savory pancakes and flatbreads, fritters, batters, thickening curries

A good structural match with comparable protein and liquid uptake, and it holds together well. It tastes distinctly beany and raw until fully cooked, so it needs proper baking or frying and is a bad idea in anything eaten raw like a no-bake bar. Expect a yellow color and a savory, legume-forward flavor rather than roasted nuts, and note it carries considerably more carbohydrate than peanut flour, so it is not a keto swap.

The flavor answer when you have peanuts in the house but no peanut flour.

Best for

smoothies, satay and dipping sauces, no-bake bars, cookies

It brings the same roasted peanut flavor, but it also brings back all the oil that was pressed out, so it is not a dry-for-dry swap. Cut about two tablespoons of butter or oil from the recipe for every two tablespoons of peanut butter you add, and expect a denser, richer, chewier result. In sauces and smoothies, where nothing depends on dry structure, it works well. In a bread or a bar that needed peanut flour for bulk, it will not hold shape.

Ground sweet lupin beans, one of the highest-protein and lowest-carb flours available.

Best for

keto breads, pasta doughs, pizza bases, high-protein bakes

Nutritionally the closest of all, very high in protein and fiber with almost no net carbohydrate, and it absorbs liquid similarly. It tastes faintly bitter and beany with a yellow tint, so a peanut butter cookie made with lupin flour tastes noticeably less sweet and more savory. Lupin is in the legume family, like peanuts, and there is a documented cross-reactivity between the two, so this is not an option for a peanut allergy.
