You’re here for Butterfinger Brownies, so let’s make them worth it. These are rich, fudgy, and packed with real chocolate flavor, with buttery edges and that signature crackly top, plus melted chocolate and crispy Butterfinger pieces in every bite, not just on top. The method is simple and reliable, with a quick mid-bake pan tap that creates that dense, glossy finish, so you get consistent, craveable results every time.

Ingredient Notes
- Mini chocolate chips – optional, but highly recommended for extra pockets of melty chocolate
- Salted butter – adds richness and balances the sweetness without extra steps
- Semi sweet chocolate chips – smooth chocolate base with just enough sweetness
- Unsweetened baking chocolate – deepens the flavor and keeps things from getting too sweet
- Eggs – give structure and that classic chewy texture
- Vanilla extract – rounds out the chocolate flavor
- Sugar – sweetens and helps create that shiny, crackly top
- All purpose flour – just enough to hold everything together
- Baking powder – gives a slight lift so they aren’t too dense
- Butterfinger pieces – the star, adds crunch and that signature flavor
