Some of the reasons for flat buttermilk biscuits include using warm ingredients, the type of leavener, the oven temperature and the mixing techniques. Buttermilk biscuits are an American food staple, and they are popular for their fluffy layers.
To make sure that buttermilk biscuits do not end up flat, always use the correct amount of baking powder to tenderize the dough. The temperature of the ingredients is also important. The butter, cream and buttermilk should be kept cold when preparing the recipe, and it is important not to overmix the ingredients. Bakers should also make sure to only re-roll any remaining biscuit scraps one time so that the dough does not become too tough to produce tender biscuits.
