  • 1 cup unsalted butter
  • 8 oz semi-sweet chocolate, chopped
  • 1 1/4 cups granulated sugar
  • 3/4 cup light brown sugar, packed
  • 4 large eggs
  • 2 tsp vanilla extract
  • 1 cup all-purpose flour
  • 1/4 cup cocoa powder
  • 1/2 tsp salt
  • 1 1/2 cups creamy peanut butter
  • 1/4 cup powdered sugar
  • 1 cup heavy cream
  • 8 oz dark chocolate, chopped


  1. Preheat Oven: Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper.

  2. Melt Butter and Chocolate: In a microwave-safe bowl, melt the butter and semi-sweet chocolate together in 30-second intervals, stirring between each until smooth.

  3. Mix Sugars, Eggs, and Vanilla: In a large bowl, whisk together the granulated sugar, light brown sugar, eggs, and vanilla extract until well combined.

  4. Combine Chocolate and Sugar Mixtures: Add the melted chocolate mixture to the sugar mixture and whisk until smooth.

  5. Sift and Fold: Sift in the flour, cocoa powder, and salt, and fold until just combined.

  6. Layer the Batter: Pour half of the brownie batter into the prepared baking pan, spreading it evenly.

  7. Prepare Peanut Butter Mixture: In a separate bowl, mix the peanut butter and powdered sugar until smooth. Drop spoonfuls of the peanut butter mixture over the brownie batter.

  8. Add Remaining Batter: Pour the remaining brownie batter over the peanut butter layer and gently spread it to cover.

  9. Bake: Bake for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.

  10. Make Ganache: While the brownies are baking, heat the heavy cream in a saucepan over medium heat until it begins to simmer. Remove from heat and add the dark chocolate. Let sit for 5 minutes, then stir until smooth to create a ganache.

  11. Finish: Once the brownies are baked and slightly cooled, pour the ganache over the top, spreading it evenly. Let the ganache set before slicing into bars.


Q: Can I use milk chocolate instead of dark chocolate? A: Absolutely! If you prefer a sweeter taste, milk chocolate can be a great substitute.

Q: How should I store these bars? A: Store them in an airtight container at room temperature for up to 5 days. You can also refrigerate them for a longer shelf life.

Q: Can I freeze these brownies? A: Yes, you can! Wrap them individually in plastic wrap and place them in a freezer-safe bag. They’ll last up to 3 months in the freezer.

Q: What if I don’t have a microwave? A: You can melt the butter and chocolate together in a double boiler over medium heat.

Q: Can I use chunky peanut butter? A: Sure thing! If you like a bit of texture, chunky peanut butter will add a nice crunch.
