Baking powder and/or baking soda need to be added to biscuit dough to make biscuits rise. Self rising flour is sold premixed with some baking powder, but I tend to add an extra half teaspoon of baking powder per cup of self rising flour when I make biscuits or pancakes with it. All purpose flour doesn't include any baking powder or baking soda.
