1 - Almond Flour
Almond flour brings a nutty sweetness that works in cakes, cookies, and muffins. The texture stays tender and moist, though it runs richer than lupin flour.

Skip if: you want a neutral base or need less fat
Chickpea Flour
Works for: savory baking, thickening sauces, flatbreads
Skip if: you want a light, fluffy crumb
2 - Chickpea Flour
Chickpea flour adds protein and structure, making it a go-to for savory baked goods and thickening soups. The flavor skews earthy and slightly bitter, so it works better in flatbreads, fritters, or stews than in cakes.
Swap 1:1 and expect a denser crumb. If you're missing chickpea flour as well, Chickpea alternatives worth trying lists legume-based flours with similar binding power.
Skip if: you need a light texture or neutral taste for delicate baking.
3 - Soy Flour
Soy flour delivers high protein and works in dense breads, muffins, and protein-rich baking. The flavor runs beany and savory, so it fits better in hearty recipes than in subtle desserts.
Use a 1:1 ratio. The texture stays firm and slightly coarse.
Pair it with other flours if you want a softer crumb.
Here's what to know:
- Adds moisture-reduce liquid slightly if the batter looks too wet.
- Browns faster-lower oven temp by 25°F or watch closely.
- Flavor builds-taste before adding extra salt or spices.
- Shelf life matters-store in the fridge to prevent rancidity.
If you're out of soy flour too, Soy Flour substitutes for cooking covers grain-based and legume options that hold structure.
Skip if: you need a light, delicate texture or want to avoid a strong beany taste.
4 - Coconut Flour
Coconut flour absorbs liquid faster than almost any other flour. Use ⅓ cup coconut flour for every 1 cup lupin flour and increase liquid by at least ¼ cup.
The flavor runs mildly sweet with a tropical edge, so it works in muffins, pancakes, and low-carb baking.
- Clumps form easily-sift before mixing.
- Batter thickens as it sits-add liquid gradually and let it rest 5 minutes.
- Eggs help bind-use at least one extra egg per cup of coconut flour.
Skip if: you need a light, airy texture or want to avoid adjusting liquid ratios.
5 - Sunflower Flour
Sunflower flour delivers a mildly nutty flavor without the sweetness of almond flour. It works in gluten-free breads, muffins, and flatbreads.
Swap 1:1 and expect a slightly denser crumb. The flavor stays earthy but won't overpower most recipes.

The texture stays dense and can turn gritty if you overmix.
Skip if: you need a fine, smooth crumb or want to avoid a grainy texture.
