- 1/4 cup milk

Instructions
- Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan.

- Combine: Gradually stir dry ingredients into the chocolate-peanut butter mixture. Add buttermilk and mix until smooth.
- Bake: Pour batter into prepared pan and bake 25–30 minutes, or until a toothpick inserted comes out clean. Let cool slightly.
- Make the icing:
- In a small saucepan, melt butter with milk and peanut butter over medium heat, stirring constantly.

- Top the cake: Pour warm icing over the slightly cooled cake and spread evenly. Allow icing to set for 10–15 minutes before slicing.
Tips for Extra Deliciousness
- Candied texture: Stir icing gently while pouring to create a slightly fudgy, candied effect.
- Crunch option: Sprinkle chopped peanuts over the icing before it sets.
