Equipment

  • 8x8-inch Baking Pan
  • Mixing Bowl
  • Microwave-safe Bowl
  • Spatula
  • Knife or Skewer

Ingredients

Ingredients

  • 4 oz Dark chocolate, chopped
  • 1/2 cup Unsalted butter
  • 1/2 cup Granulated sugar
  • 1/2 cup Brown sugar, packed
  • 2 large Eggs
  • 1 teaspoon Pure vanilla extract
  • 2/3 cup All-purpose flour
  • 1/4 cup Cocoa powder
  • 1 teaspoon Salt
  • 1/2 teaspoon Espresso powder
  • 1/4 cup Natural salted creamy peanut butter, warmed until pourable

Instructions

  • Preheat your oven to 350°F (175°C). Line an 8x8 inch baking pan with parchment paper or lightly grease it, leaving some overhang for easy removal.
  • In a microwave-safe bowl, melt the chopped dark chocolate and butter in 20-second increments, stirring after each one until smooth and glossy. Set aside to cool slightly.
  • In a large mixing bowl, whisk together the granulated sugar, brown sugar, eggs, and vanilla extract until the mixture becomes pale and slightly fluffy—about 2 minutes.
  • Pour the cooled chocolate-butter mixture into the egg and sugar mixture, stirring until fully combined.
  • Over the wet mixture, sift in the flour, cocoa powder, salt, and espresso powder. Gently fold the dry ingredients in with a spatula, mixing just until no flour streaks remain.
  • Pour the rich, chocolatey batter into your prepared pan, smoothing the top with a spatula.
  • Drizzle the warmed creamy peanut butter in several horizontal lines across the batter’s surface. Using a thin knife or skewer, gently swirl the peanut butter into the brownie batter. Don’t over-mix—the goal is a rippled, marbled look.
  • Bake for 25-30 minutes, or until a toothpick inserted near the edge comes out mostly clean with a few moist crumbs attached. For extra-gooey centers, err on the shorter baking time.
  • Cool completely in the pan, then lift out using the parchment overhang. Slice into squares and enjoy!

Notes

For the fudgiest result, err on the side of slightly under-baking. Cool completely before slicing for neat squares.
