Step‑by‑Step Instructions for peanut butter cup dump cake
Step 1: Preheat and Prepare
Begin by preheating your oven to 350°F (175°C). While the oven warms, grab a 9×13-inch baking dish and lightly coat it with cooking spray to prevent sticking. This step ensures your peanut butter cup dump cake will slide right out once baked, making serving a breeze.
Step 2: Spread the Peanut Butter
Take your room-temperature peanut butter and use a spatula to spread it evenly across the bottom of the prepared baking dish. Aim for a smooth, even layer that will form the delicious base of your cake. This creamy layer will infuse the cake with rich flavor as it bakes.
Step 3: Mix the Batter
In a large mixing bowl, combine the chocolate cake mix, melted butter, and milk. Stir the ingredients together with a whisk or spoon until just mixed and smooth. Be careful not to overmix; you want to keep the batter light and airy for that perfect texture in your peanut butter cup dump cake.
Step 4: Pour the Batter
Once your batter is ready, gently pour it over the peanut butter layer in the baking dish. Use a spatula to spread it evenly if needed. Watch as the rich chocolate cake batter mixes harmoniously with the creamy peanut butter below—it’s already looking delicious!
Step 5: Add the Toppings
Sprinkle mini peanut butter cups evenly over the top of the chocolate batter. You can also add a handful of chocolate chips for an extra touch of sweetness and texture. This layer of toppings will create delightful pockets of flavor as the cake bakes.
Step 6: Bake the Cake
Place the baking dish in the preheated oven and bake for 35-40 minutes. Keep an eye on it as the edges should pull away slightly from the pan, and a toothpick inserted in the center should come out with moist crumbs. This visual cue ensures your peanut butter cup dump cake is perfectly baked.
Step 7: Cool and Serve
After baking, remove the cake from the oven and let it cool for 15 minutes before slicing. This cooling time allows the layers to set beautifully. Serve warm for an indulgent dessert that will melt your heart with every gooey bite!

When you’re ready to bake, just remove it from the fridge, sprinkle the mini peanut butter cups on top, and pop it in a preheated oven!

Expert Tips for Peanut Butter Cup Dump Cake
-
Room Temperature Peanut Butter: Let your peanut butter sit out for about 30 minutes; this makes it much easier to spread across the baking dish.
-
Avoid Overmixing: When combining your cake mix with melted butter and milk, mix until just combined. Overmixing can lead to a dense and dry texture in your peanut butter cup dump cake.
-
Check for Doneness: Keep an eye on the baking time; taking it out when the edges are just pulling away from the pan will ensure a perfect fudgy center.
-
Adjust Consistency: If your batter looks too thick, add a splash of milk to create a smoother consistency before pouring it over the peanut butter layer.
-
Serving Suggestions: For a delightful experience, serve your cake warm with a scoop of vanilla ice cream on top—this adds a creamy contrast that enhances the chocolate-peanut flavor.

Peanut Butter Cup Dump Cake Recipe FAQs
What type of peanut butter should I use?
I recommend using creamy peanut butter for the best texture and flavor. It spreads easily across the pan. If you’re looking for a twist, almond butter is a great alternative, adding a unique flavor while still delivering creaminess.
How do I store the leftover peanut butter cup dump cake?
You can keep your peanut butter cup dump cake in an airtight container at room temperature for about 3 days. If you want to extend its life, feel free to refrigerate it, where it will last for up to a week. Just make sure to cover it well to prevent it from drying out!
Can I freeze the peanut butter cup dump cake?
Absolutely! To freeze, wrap the cake tightly in plastic wrap and then in aluminum foil to protect it from freezer burn. It will stay fresh for up to a month. When you’re ready to enjoy it again, simply thaw it in the fridge overnight and reheat individual slices in the microwave for that freshly baked taste!
What should I do if the cake turns out too dry?
If your peanut butter cup dump cake is too dry, it may have been overbaked. Next time, be sure to check the cake about 5 minutes before the recommended baking time. A toothpick should come out with moist crumbs, not completely clean. If it happens, drizzle a bit of milk on slices when serving to add moisture!
Is this recipe suitable for people with nut allergies?
Since the primary flavors in this recipe come from peanut butter and mini peanut butter cups, it’s not suitable for people with nut allergies. However, you can make a nut-free version by substituting peanut butter with sunflower seed butter, which gives a similar creamy texture while ensuring safety for those with nut sensitivities. Always double-check ingredient labels for potential allergens!
Can I use different cake mixes for variety?
Yes, you can! If you prefer a lighter flavor, swap out the chocolate cake mix for a yellow or vanilla cake mix. This will give your peanut butter cup dump cake a different taste profile while still keeping that rich and gooey texture that everyone loves!
