How much baking powder to use with gluten free plain plour?

When using gluten-free plain flour, a general guideline is to use about 1 to 1.5 teaspoons of baking powder per cup of flour. This amount helps provide the necessary lift and texture since gluten-free flours often require more leavening than traditional wheat flour. Always check the specific recipe for any adjustments, as different gluten-free blends may vary in their absorption and performance.
