Baking has a special way of connecting us with memories, whether it’s recreating family traditions or trying out a recipe that speaks to our love for a certain flavor combination. A few months ago, I was on a mission to create a dessert that combined two of my all-time favorites: chocolate and peanut butter.
The richness of chocolate paired with the creaminess of peanut butter never fails to satisfy my sweet tooth. As I set out to make the ultimate indulgence, I couldn’t help but get excited about the gooey, melt-in-your-mouth texture that I was aiming for. And thus, the Chocolate Peanut Butter Ooey Gooey Butter Cake was born.
With every bite, this cake was everything I hoped for—decadent, rich, and oh-so-satisfying. The layers of soft, chocolatey cake, creamy peanut butter filling, and light dusting of powdered sugar come together in perfect harmony, making each slice an unforgettable treat. This dessert is sure to bring a smile to anyone who tries it. Let me walk you through this delicious creation.
Short Description
This Chocolate Peanut Butter Ooey Gooey Butter Cake combines rich chocolate cake layers with a creamy peanut butter filling, creating a decadent dessert that’s sure to satisfy every sweet tooth. Perfect for chocolate and peanut butter lovers, this cake is simple yet indulgent, with a soft, gooey texture that melts in your mouth.
Key Ingredients
For the Cake Layers:
- 1 box chocolate cake mix (plus ingredients specified on the package)
- 1/2 cup creamy peanut butter
- 1/2 cup milk
For the Filling:
- 1 cup creamy peanut butter
- 1 cup powdered sugar
- 1/2 cup unsalted butter, softened
- 1 tsp vanilla extract
For Assembly:
- Additional powdered sugar (for dusting)
- Optional toppings: chopped peanuts, chocolate drizzle, whipped cream
Tools Needed
- Two 8-inch round cake pans
- Parchment paper (if lining pans)
- Electric mixer (or a whisk for manual mixing)
- Large mixing bowls
- Measuring cups and spoons
- Cooling rack
Cooking Instructions
Step 1: Preheat Your Oven
Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans, or line them with parchment paper for easy removal later.
Step 2: Make the Cake Batter
Prepare the chocolate cake mix according to the instructions on the box. Add the creamy peanut butter and milk to the batter and mix until smooth and well-combined. Divide the batter evenly between the two prepared pans.
Step 3: Bake the Cake Layers
Bake the cakes in the preheated oven for 25–30 minutes. Check doneness by inserting a toothpick into the center—it should come out clean when the cakes are done. Let the cakes cool completely in the pans on a cooling rack. Patience is key, as this ensures the cakes set properly for the next steps.
Step 4: Prepare the Filling
In a large mixing bowl, combine the creamy peanut butter, powdered sugar, softened butter, and vanilla extract. Beat the mixture until it’s smooth, creamy, and fluffy. The peanut butter filling will be thick, but it should spread easily once it’s on the cake.
Step 5: Assemble the Cake
Once the cake layers have cooled, place one cake layer on a serving plate. Spread half of the peanut butter filling evenly over the top. Top with the second cake layer and spread the remaining filling over the top and sides. Don’t worry if it’s a little messy—the gooey filling is part of the charm!
Step 6: Dust & Decorate
Dust the cake generously with powdered sugar for a sweet, elegant finish. For added texture and flavor, garnish with chopped peanuts, a drizzle of melted chocolate, or a dollop of whipped cream.
Step 7: Serve
Slice the cake into generous pieces and serve immediately. For an extra treat, enjoy the cake slightly warm, or chill it in the refrigerator for a firmer slice.

Mistakes to Avoid & Solutions
Cake layers not fully cooked
Solution: Always check the cakes with a toothpick to make sure they’re baked all the way through. If the toothpick comes out with wet batter, bake for a few more minutes and test again.
Filling too thick or hard to spread
Solution: If the peanut butter filling is too thick, add a small splash of milk to loosen it up. This will help it spread evenly without tearing the cake.
Cake layers stick to the pan
Solution: Be sure to grease and flour your pans well or line them with parchment paper for easy removal. This helps prevent any frustration when trying to get the cake out!
Not letting the cake cool properly
Solution: Cooling the cake completely in the pans allows the layers to set before adding the filling. If the cake is still warm, the filling may melt too much and become runny.
Serving and Pairing Suggestions
– Serve it with a scoop of vanilla ice cream for an added creamy contrast to the cake’s rich texture.
– Pair with iced coffee or a rich hot chocolate for an indulgent dessert experience.
– Serve at room temperature or chilled depending on your texture preference; chilled slices are easier to cut and serve for gatherings.
FAQs
1. Can I use a different cake mix flavor?

3. Can I freeze this cake?

4. Can I use crunchy peanut butter for the filling?
Definitely! Crunchy peanut butter will give the filling a bit of extra texture and a fun twist.
5. How do I know when the cake layers are fully baked?
Use a toothpick or cake tester to check for doneness. If it comes out clean or with a few moist crumbs, the cake is done.

For a lighter filling, you can fold in some whipped cream to the peanut butter mixture for a fluffier texture.
