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

Tools You’ll Need

Before you dive in, grab these tools so everything comes together easily.

Tips for Success

  • Chill before slicing, it makes a big difference in clean cuts
  • Let the melted chocolate cool slightly before mixing, it keeps the eggs from scrambling
  • Stir, don’t beat, this keeps the texture dense and fudgy
  • Tossing the Butterfinger pieces in flour helps them stay evenly distributed
  • Don’t over bake, a slightly soft center firms up as it cools

FAQ

Why do you tap the pan during baking?

It helps release air bubbles and creates a denser texture with that signature crinkly top.

Can I use a metal pan instead of glass?

Yes, just keep an eye on baking time since metal pans can bake faster.

How do I know when brownies are done?

A toothpick should come out mostly clean with a few moist crumbs, not wet batter.

These butterfinger brownies hit that perfect balance of rich, fudgy, and crunchy. Once you make them, you’ll keep coming back to this exact version. The printable recipe card is below. Have a great day, friends!

Instructions
 

  • Preheat oven to 350 degrees. Line a 9×9 square glass baking dish with parchment paper and spray lightly with nonstick cooking spray. Set aside.
  • In a double boiler, melt butter, chocolate chips and unsweetened baking chocolate. Stir occasionally until completely smooth and melted. Remove from heat and cool 15 minutes.
  • In a large bowl, stir eggs, vanilla and sugar {do not beat}. Pour in warm chocolate butter mixture and stir. Set aside to cool to room temperature, another 15 minutes or so.
  • Stir in flour, baking powder & salt until combined. In a separate bowl, stir butterfinger bits with mini chocolate chips and 1 tablespoon of flour. Pour into batter and stir.
  • Pour batter into prepared pan and bake 15 minutes. Rap pan against the oven shelf to force the air to escape from between the pan and the brownie dough. Bake for about 10 minutes, until a toothpick comes out clean. Do not overbake! Allow to cool thoroughly, refrigerate, and cut into squares.

    I just bought some butterfinger bits! Perfect timing. One question, you wrote the recipe was based on one by Ina (love her), and frosting by you….is the supposed to be frosting on these? I don’t see a recipe for frosting. I can’t wait to try these!
