How to Make Peanut Butter Cup Dump Cake: Step-by-Step Instructions
Follow these easy steps to create the most decadent peanut butter and chocolate dessert your kitchen has ever seen:
Step 1: Preheat & Prepare
Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with non-stick spray or butter. This will help ensure easy serving and cleanup.
Step 2: Mix the Cake Batter
In a large mixing bowl, combine:
- 1 box chocolate cake mix
- 1/2 cup vegetable oil
- 1 cup milk
- 3 large eggs
- 1 tsp vanilla extract
Mix until smooth and creamy. A hand mixer works well here, but a sturdy whisk will do the trick too.
Step 3: Layer the First Half
Pour half of the cake batter into your prepared baking dish and spread it out evenly with a spatula.
Step 4: Add the Peanut Butter Magic
Drop spoonfuls of creamy peanut butter over the cake batter. No need to spread it perfectly—these pockets of peanut butter melt into irresistible bites.
Then, sprinkle half of the chocolate chips and half of the chopped peanut butter cups over the batter.
Step 5: Top It Off
Pour the remaining cake batter over the top and gently smooth it out. Finish by sprinkling the rest of your chocolate chips and peanut butter cups evenly across the top.
Step 6: Bake to Perfection
Bake in the preheated oven for 30 to 35 minutes, or until a toothpick inserted into the center comes out mostly clean (a few moist crumbs are okay).
Step 7: Cool and Serve
Let the cake cool for about 10-15 minutes. Then, if desired, dust the top with powdered sugar for a touch of elegance and sweetness.
Serve warm for maximum gooey goodness, or at room temperature if you prefer a more set texture.
Tips for Success
Here are some pro tips to help you nail this peanut butter dump cake every time:
- Don’t overmix the batter. Mixing until just combined helps keep the cake moist and tender.
- Warm the peanut butter slightly for easier spooning and better spreadability.
- Try it with ice cream! A scoop of vanilla or peanut butter ice cream takes this dessert to the next level.
- Customize your mix-ins: Swap chocolate chips for white chocolate, or add crushed pretzels for a salty crunch.
Storage & Make-Ahead Tips
This cake stores surprisingly well, making it perfect for prepping ahead:
- Refrigerate: Store leftovers in an airtight container in the refrigerator for up to 5 days.
- Reheat: Pop a slice in the microwave for 15–30 seconds to bring back that warm, gooey texture.
- Freeze: Freeze individual slices for up to 2 months. Wrap tightly in plastic wrap and foil before placing in a freezer bag.
Frequently Asked Questions (FAQs)
Can I use natural peanut butter?
Yes, but be aware that natural peanut butter tends to be thinner and oilier. Stir it well before using, or opt for a thicker variety to maintain structure.
Can I make this recipe gluten-free?
Absolutely! Just use your favorite gluten-free chocolate cake mix and double-check that all other ingredients are certified gluten-free.
Can I use mini peanut butter cups or different candies?
Totally! Mini cups are easier to chop, and candies like Reese’s Pieces, chopped Snickers, or even caramel bits can be fun additions.
What if I don’t have a cake mix?
You can make your own chocolate cake base from scratch, but using a mix keeps this recipe quick and easy—true to the dump cake spirit!
