Ingredients

Scale

1 box chocolate cake mix
1/2 cup melted butter
1/2 cup creamy peanut butter
1 cup milk
2 large eggs
1 teaspoon vanilla extract
1 1/2 cups chopped peanut butter cups (plus extra for topping)
Optional toppings: whipped cream, vanilla ice cream, chocolate or caramel drizzle, crushed pretzels

Instructions

Preheat: Heat oven to 350°F (175°C) and lightly grease a 9×13-inch baking dish.
Mix base: In a large bowl, whisk together cake mix, melted butter, milk, eggs, and vanilla until combined.
Layer peanut butter: Spread half the batter into the baking dish. Drop spoonfuls of peanut butter over the batter and swirl gently.
Add candy: Sprinkle chopped peanut butter cups evenly over the layer.
Top with batter: Spread the remaining cake batter on top.
Bake: Bake for 30–35 minutes, until a toothpick inserted comes out mostly clean (gooey is okay).
Serve: Top with extra peanut butter cups and serve warm with ice cream or whipped cream.

Notes

Don’t overbake—the cake should be moist and slightly gooey in the middle.
Use room-temperature eggs for better texture.
Add more peanut butter cups to the batter for extra indulgence.
Line pan with parchment for easier cleanup.
Drizzle melted chocolate or caramel after baking for added richness.
