Tips & Variations
- For a fudgier texture, use half milk and half heavy cream instead of all milk in the peanut butter mixture.
- You can swap mini peanut butter cups for chopped full-size cups or peanut butter chips for a different texture.
- If you prefer crunchy peanut butter, it adds a nice contrast to the smooth batter.
- To make this gluten-free, use a gluten-free chocolate cake mix and check your peanut butter cups for gluten ingredients.
Storage

FAQs
Can I use natural peanut butter instead of creamy?
Yes, you can use natural peanut butter, but be aware that it may alter the texture slightly as natural peanut butter tends to separate. Stir it well before measuring and mixing for best results.
Do I need to grease the baking dish?
Yes, greasing the dish helps prevent the cake from sticking and makes serving easier. You can use butter, non-stick spray, or even line the dish with parchment paper if preferred.

Ingredients
Base Mixture
- 1 can (14 oz) sweetened condensed milk
- 1 cup milk (any kind works!)
- 1/2 cup creamy peanut butter
- 1 teaspoon vanilla extract
Dry Ingredients
- 1 box (15.25 oz) chocolate cake mix
Topping
- 1/2 cup butter, melted
- 1 (10-12 oz) bag of mini peanut butter cups, unwrapped (Reese’s recommended)
Optional Garnishes
- Chocolate syrup for drizzling
- Whipped cream or vanilla ice cream for serving
Instructions
- Prepare Peanut Butter Mixture: In a large bowl, combine sweetened condensed milk, milk, creamy peanut butter, and vanilla extract. Mix thoroughly until the mixture is smooth and well combined. This creates the moist base for the cake.
- Prepare Baking Dish: Preheat your oven to 350°F (175°C). Generously grease a 9×13 inch baking dish to prevent sticking and make cleanup easier.
- Assemble Dump Cake: Pour the prepared peanut butter mixture evenly into the greased baking dish. Next, sprinkle the chocolate cake mix uniformly over the peanut butter layer. Then, drizzle the melted butter evenly over the entire surface to help create a rich, gooey texture as it bakes.
- Add Peanut Butter Cups: Evenly scatter the unwrapped mini peanut butter cups across the top of the cake mix, pressing them down slightly so they settle into the batter for a melty, peanut buttery surprise in every bite.
- Bake: Place the baking dish in the preheated oven and bake for 30 to 35 minutes. The cake is done when the top turns golden brown and a toothpick inserted into the center comes out with moist crumbs attached, indicating it’s perfectly cooked but still gooey.
- Cool: Remove the cake from the oven and allow it to cool for at least 15 to 20 minutes. Cooling lets the cake set, making it easier to cut and serve.
- Serve: Optionally drizzle chocolate syrup on top for extra decadence. Serve the dump cake warm with a dollop of whipped cream or a scoop of vanilla ice cream for an irresistible dessert experience.
