Related to Plain Flour
Bread Flour
A straight swap with more protein (150 g vs 140 g per cup), so gluten develops further and the crumb turns chewier. Good in pizza, bagels, and rustic loaves; in delicate cakes it can read tough, so reserve it for bakes that want structure. See our Bread Flour converter.
Cake Flour
The tender-crumb swap: cake flour is softer and lower in protein, 7 to 9% against 10 to 12%, giving a finer, lighter result in sponges and cupcakes (130 g vs 140 g per cup). Avoid it for bread and pizza, where the weaker gluten leaves the dough slack. No cake flour on hand? Take 2 tablespoons out of a cup of plain flour and replace them with cornstarch. See our Cake Flour converter.
Self Raising Flour
Self-raising flour is plain flour with baking powder already blended in, matched in weight per cup (140 g each). Use the self-raising flour calculator to make your own from plain flour, or swap to plain flour and add your own leavener. See what 100 grams of self raising flour is in US cups.
