Step‑by‑Step Instructions for Peanut Butter Cup Dump Cake
Step 1: Prepare Peanut Butter Mixture
In a mixing bowl, combine sweetened condensed milk, milk, creamy peanut butter, and vanilla extract. Stir these ingredients together until they reach a smooth, even consistency, ensuring no lumps remain. This mixture will provide a rich base for your Peanut Butter Cup Dump Cake, infusing it with creamy flavor throughout.
Step 2: Preheat Oven
Preheat your oven to 350°F (175°C) while you prepare the baking dish. Grease a 9×13 inch baking dish generously with butter or non-stick spray. The greased surface is essential for easy removal of your delicious dump cake once it’s baked, allowing for a perfect presentation when serving your family and friends.
Step 3: Assemble Dump Cake
Pour the peanut butter mixture evenly into the prepared baking dish, spreading it gently to cover the bottom. Next, carefully sprinkle the chocolate cake mix over the top of the peanut butter layer, ensuring an even distribution. Drizzle the melted butter over the cake mix, allowing it to seep down, which helps create a moist texture in your Peanut Butter Cup Dump Cake.
Step 4: Add Peanut Butter Cups
Take your mini peanut butter cups and evenly distribute them over the top of the cake mix layer. Press them down lightly to ensure they incorporate into the cake while baking, which will create delightful pockets of melted peanut butter cups throughout. This step is crucial for adding that irresistible peanut butter flavor that will delight everyone!
Step 5: Bake
Transfer the assembled Peanut Butter Cup Dump Cake to your preheated oven and bake for 30–35 minutes. Watch for the top to turn golden brown and a toothpick inserted in the center to come out with moist crumbs. This will signal that your cake is perfectly baked and ready to be enjoyed by everyone at the table.
Step 6: Cool
Once the baking time is complete, remove the cake from the oven and let it cool for 15–20 minutes on a wire rack. This cooling period allows the cake to set slightly, making it easier to slice and serve. Don’t rush this step, as patience will reward you with a more enjoyable texture when serving your delicious dessert.
Step 7: Serve
For the final touch, drizzle the warm Peanut Butter Cup Dump Cake with chocolate syrup, if desired, for an extra layer of sweetness. Serve each piece topped with whipped cream or a scoop of vanilla ice cream to create a delightful contrast of flavors and temperatures. Your decadent dessert is now ready, and it’s bound to impress everyone!

This method will keep the cake protected from freezer burn for up to 3 months. When you’re ready to indulge, simply thaw overnight in the refrigerator and reheat in the microwave for 15-30 seconds.
What should I do if my dump cake is too dry?
Very good question! If you find your Peanut Butter Cup Dump Cake has turned out a bit dry, it may be because it was overbaked. In the future, try checking it a couple of minutes before the suggested baking time. The cake should have a golden top and a toothpick should come out with moist crumbs, not completely clean. If it has already dried out, you can drizzle a bit of warmed chocolate syrup or serve it with whipped cream or ice cream to add moisture back in.
Is this dessert suitable for people with nut allergies?
I often recommend caution! This recipe contains peanut butter, so it’s not suitable for those with peanut allergies. Consider using sunflower seed butter or a different nut-free alternative if you’re looking to accommodate guests with allergies. Always check labels to ensure all ingredients are allergy-friendly!
Can I make this recipe vegan?
Absolutely! You can make your Peanut Butter Cup Dump Cake vegan by replacing the sweetened condensed milk with a non-dairy milk combined with a thickener like cornstarch or soy yogurt. For the butter, use a dairy-free alternative like coconut oil or vegan butter. Be sure to use a vegan cake mix and dairy-free chocolate for anything you choose to add! This way, everyone can enjoy this delicious dessert.
