Method
- Preheat your oven according to the directions on the cake mix box. Grease and lightly flour a 9×13-inch baking dish. Prepare the cake mix as directed, then stir in 1 cup of creamy peanut butter. Mix until smooth and pour into the prepared dish. Bake as instructed, typically 30–35 minutes.
- Allow the cake to cool for about 15 minutes. Using the handle of a wooden spoon or skewer, poke holes evenly over the surface — about 1 inch apart.
- In a bowl, whisk together sweetened condensed milk and melted peanut butter until smooth and pourable. Slowly pour the mixture over the cake, letting it fill all the holes. Let the cake absorb the filling completely.
- Refrigerate for at least 1 hour to let the flavors blend and the filling firm up slightly.
- Spread the whipped topping evenly over the chilled cake using a spatula. Make sure it covers the surface completely for a smooth layer.
- Sprinkle the top with mini chocolate chips and chopped peanut butter cups for extra flavor and crunch. Slice into squares and serve chilled.
Notes
For extra peanut butter flavor, drizzle melted peanut butter over the whipped topping before serving. You can use any chocolate cake mix — Devil’s Food, Fudge, or German Chocolate all work great. Best served chilled for a creamy, refreshing texture.
