do you have to use baking powder in muffins?
See more baked goods in these pictures of cakes and cupcakes. If you have read How Bread Works, then you understand how the release of carbon dioxide by yeast can cause bread to rise. Many recipes, however, use no yeast. Things like muffins, biscuits, cakes and cookies usually use baking powder instead. All three need to be dry powders that can be mixed together. For example, baking soda (a base), cream of tartar (an acid) and corn starch (the filler) are three common ingredients.
