Related to Oat Flour
Plain Flour
Plain flour brings gluten that oat flour lacks, so the crumb holds together better but loses the gluten-free benefit. Oat flour is lighter per cup (100 g vs 140 g), so weigh rather than scoop and expect a slightly firmer, less crumbly bake. See our Plain Flour converter.
Almond Flour
Keeps the bake gluten-free while adding richness and moisture. Almond flour (96 g/cup) has no starch to set, so it works best in cookies, muffins, and dense cakes rather than anything needing a tall, airy rise. See our Almond Flour converter.
Almond Meal
Ground almonds are roughly 50 percent fat, so almond meal absorbs far less liquid than oat flour does. If you substitute almond meal for oat or regular flour, reduce the butter or oil by about a tablespoon per cup of flour to avoid your bake turning greasy. Both almond meal and oat flour weigh 100 g per metric cup, so they are a 1:1 swap for both weight and volume. See our Almond Meal converter.
Rolled Oats
Oat flour is rolled oats milled to a powder, so the two are close in weight (100 g vs 90 g per cup). Blitz rolled oats in a blender to make your own oat flour, or weigh the flour when a recipe needs the fine, ready-ground form. See what 50 grams of rolled oats is in cups.
Bread Flour
Bread flour sits at the top of the wheat protein range (around 12 to 14%) and oat flour has no gluten at all, so they do opposite jobs in a dough. A quarter of the flour in a yeasted loaf is about as much oat flour as it will take before the rise gives out. See what 100 grams of bread flour is in cups.
Cake Flour
Both bake soft, for opposite reasons: cake flour because its protein sits low (around 7 to 9%), oat flour because it carries no gluten-forming protein at all. A cup holds 130 g of cake flour against 100 g of oat flour, so the scales matter more than the scoop when you trade one for the other. See our Cake Flour converter.
Self Raising Flour
Self-raising flour arrives with its leavener already blended in and oat flour has none, so an oat-flour version of the same recipe needs baking powder stirred through before it will rise. The self-raising flour calculator gives the amount for any weight. See what 100 grams of self raising flour is in cups.
