Instructions

Preparation

  • Preheat your oven to 350°F (175°C). Grease and flour an 8-inch square baking pan.
  • In a large mixing bowl, whisk together the flour, granulated sugar, cocoa powder, baking powder, baking soda, and salt.
  • In another bowl, combine the melted butter, creamy peanut butter, buttermilk, egg, and vanilla extract. Mix until well incorporated and smooth.
  • Gradually add the dry mixture to the wet ingredients, stirring together until just combined.
  • Stir in the boiling water until the batter appears smooth and thin.
  • Gently fold in the chocolate chips and peanut butter chips.

Baking

  • Pour the batter into the prepared baking pan and place it in the preheated oven.
  • 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 generous squares.

Notes

Use room temperature ingredients for better mixing. Don’t skip the boiling water; it’s essential for the ooey-gooey center. Feel free to customize with different types of chips.
