Ingredients

Scale

Brownie Batter

  • 1 & 1/4 cups salted butter
  • 2 & 1/2 cups granulated sugar
  • 1 cup unsweetened cocoa powder
  • 1/2 teaspoon salt
  • 1 tablespoon water
  • 2 teaspoons vanilla extract
  • 4 large eggs
  • 1 cup all-purpose flour

Filling

  • 12 large Reese’s Peanut Butter Cups


Instructions

  1. Preheat Oven: Preheat your oven to 350 degrees F to get it ready for baking the brownies evenly.
  2. Prepare Baking Dish: Line a 9×13 inch baking dish with parchment paper or foil and spray it with non-stick cooking spray, or directly spray the pan to prevent sticking.
  3. Buckle Up Butter: In a large saucepan over medium heat, melt the butter. Stir occasionally as it foams, then subsides, and starts browning. Wait until the butter develops light brown milk solids and a nutty aroma—this signals perfectly browned butter.
  4. Mix Dry Ingredients: While the butter browns, in a separate bowl or mixer, combine granulated sugar, cocoa powder, and salt.
  5. Combine Butter and Dry Mix: Immediately pour the hot browned butter into the sugar and cocoa mixture to halt cooking, then beat until smooth and creamy in texture.
  6. Add Liquids and Eggs: Stir in water and vanilla extract. Then add eggs one at a time, mixing thoroughly between each addition to combine fully.
  7. Incorporate Flour: Gradually add the all-purpose flour and mix until just combined. The batter should be thick, like cement, rich in texture and flavor.
  8. Spread Batter: Using a sturdy rubber spatula, evenly spread the thick batter into the prepared baking pan.
  9. Add Reese’s Cups: Unwrap 12 large Reese’s Peanut Butter Cups and press them gently but firmly into the batter. Swirl the top with a spatula so the peanut butter cups are slightly covered by the batter.
  10. Bake: Bake in the preheated oven for 25 to 30 minutes or until a toothpick inserted in the center comes out clean of batter but may have moist crumbs, indicating fudgy center.

Notes

  • Watch the butter carefully when browning to avoid burning; remove from heat once it smells nutty and turns light brown.
  • Do not overmix the batter after adding flour to retain fudgy brownie texture.
  • Line the baking dish for easy removal and clean-up.
  • Allow brownies to cool before slicing for clean, defined pieces.
  • You can substitute salted butter with unsalted but add a pinch more salt if desired.
