Ingredients

Scale
  • 1 cup (227 g) unsalted butter, melted
  • 2 cups (400 g) granulated sugar
  • 3 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 1 cup (125 g) all-purpose flour (can substitute almond flour for gluten-free)
  • ¾ cup (75 g) unsweetened cocoa powder, sifted
  • ½ teaspoon salt
  • ¾ cup (190 g) smooth and creamy peanut butter
  • 1 cup (about 68 cups) peanut butter cups, chopped

Instructions

  1. Preheat your oven to 350°F (175°C). Lightly grease an 8×8-inch baking pan or line it with parchment paper, leaving some overhang for easy removal.
  2. Melt the butter in a microwave-safe bowl or on the stovetop. Let it cool slightly.
  3. In a large mixing bowl, whisk together the granulated sugar and eggs until pale and slightly thickened, about 2-3 minutes.
  4. Add the melted butter and vanilla extract to the sugar-egg mixture, stirring until smooth and shiny.
  5. In a separate bowl, sift together the cocoa powder, all-purpose flour, and salt.
  6. Gently fold the dry ingredients into the wet mixture using a spatula, stirring just until combined.
  7. Pour half the batter into the prepared pan, spreading evenly.
  8. Warm the peanut butter slightly in the microwave for 15-20 seconds to soften.
  9. Dollop spoonfuls of peanut butter over the brownie batter.
  10. Drop chopped peanut butter cups evenly over the peanut butter dollops.
  11. Top with the remaining brownie batter and smooth out gently.
  12. Using a knife or skewer, swirl the peanut butter and batter together to create creamy swirls without overmixing.
  13. Bake in the preheated oven for 30-35 minutes. Check at 30 minutes by inserting a toothpick; it should come out with moist crumbs but not wet batter.
  14. Cool completely in the pan on a wire rack before slicing.

Notes

Use room temperature eggs for better texture. Avoid overmixing the batter to keep brownies fudgy. Gently swirl peanut butter to maintain pretty marbled effect. Freeze peanut butter cups for 10 minutes before chopping to reduce stickiness. Check brownies at 30 minutes to avoid overbaking. Cool completely before slicing for neat cuts.
