Instructions

Preparation

  • Preheat the oven to 350°F (175°C) and grease and flour an 8-inch square baking pan.
  • In a large bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt until well combined.
  • In another bowl, mix together the melted butter, peanut butter, buttermilk, egg, and vanilla extract until thoroughly combined.
  • Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
  • Stir in the boiling water until the batter becomes smooth and thin.
  • Fold in the chocolate chips and peanut butter chips.
  • Pour the batter into the prepared baking pan and bake for 30-35 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs.
  • Allow the cake to cool completely in the pan before cutting it into squares.
  • Optional: sprinkle with chopped peanuts for an extra crunch.

Notes

Use high-quality cocoa powder and peanut butter for the best flavor. Allowing your cake to cool completely will help maintain its shape when you cut it. For extra richness, consider drizzling melted chocolate or peanut butter over the top before serving.
