What Is a Brookie?

A Brookie is a dessert hybrid made by layering brownie batter with cookie dough, then baking them together into a single bar or cookie-style treat. The brownie layer provides moisture and richness, while the cookie layer adds structure, sweetness, and texture.
Because Brookies include ingredients from both desserts, such as butter, sugar, flour, eggs, and chocolate, their calorie content is naturally higher than eating a brownie or cookie on its own. This unique composition is the main reason calories in Brookie vary widely depending on how they are made and served.
