Tips & Variations for this recipe

Reese's Cup Brownies FAQ
Brownies will typically call for eggs and oil, creating a very moist and fudgy brownie. However, our recipe doesn't contain oil, with the exception of any oils added to the candy pieces, but is still just as moist and fudgy.
Baking powder and baking soda will help to lift and fluff your brownies giving them a cakey texture. If your recipe calls for two eggs, removing an egg will also give a cakey, fluffy texture.
Most brownies will have their toppings added before baking. Brownies that have a drizzle, or a dusting of powdered sugar will have their toppings added after they've been baked and cooled.
