Ingredients You’ll Need
These ingredients are straightforward and easy to find, yet each one plays a crucial role in building layers of flavor and texture that make this cake irresistible. From the fudgy cake base to the creamy peanut butter frosting and the melty chocolate chips, every component works in harmony.
- Chocolate fudge cake mix: The foundation of the cake, providing a rich and moist chocolate base with ease.
- Butter (1/2 cup): Adds richness and helps to create the smooth frosting texture when melted.
- Cream cheese (8 ounces, softened): Gives the frosting a tangy creaminess that balances the sweetness perfectly.
- Peanut butter (1/2 cup): The star flavor that brings a nutty, luscious depth to the frosting.
- Vanilla extract (1/2 teaspoon): Enhances the overall flavors and adds a subtle warmth to the frosting.
- Powdered sugar (3 1/2 to 4 cups): Sweetens and thickens the frosting to just the right consistency for dolloping.
- Chocolate chips (1/2 cup): Adds bursts of melted chocolate throughout the cake once baked.
- Chocolate peanut butter cups (1 cup, halved): A delightful surprise that melts into pockets of gooey, nutty goodness.
How to Make Chocolate Peanut Butter Earthquake Cake Recipe
Step 1: Preheat and Prepare the Cake Base
Start by preheating your oven to 350°F (175°C). While waiting, prepare your chocolate fudge cake mix according to the package instructions. Instead of baking it immediately, pour the batter into a lightly greased 9×13 inch pan and set it aside. This uncooked batter will soon mingle beautifully with the peanut butter frosting, creating the “earthquake” effect this cake is famous for.
Step 2: Make the Peanut Butter Frosting
Place the butter in a saucepan over medium heat and melt it until bubbly but not browned. Transfer the melted butter to a mixing bowl and beat together with softened cream cheese until the mixture is silky smooth. Add the peanut butter and vanilla extract, and continue beating until fully incorporated. Gradually add powdered sugar, starting with 3 1/2 cups and adding more if needed, until the frosting becomes light, fluffy, and spreadable. This creamy frosting will contrast perfectly with the dense chocolate cake.
Step 3: Assemble the Cake Layers
Take generous spoonfuls of the peanut butter frosting and drop them across the surface of the uncooked chocolate cake batter. Think of it like creating flavorful pockets that will ripple through the cake as it bakes. Then sprinkle chocolate chips and halved peanut butter cups evenly over the top. These add texture and little bursts of gooey deliciousness once baked.
Step 4: Bake and Cool
Place your pan in the oven and bake for 45 to 55 minutes. The center should still jiggle slightly when you gently shake the pan—it will continue to set as it cools. Once done, remove the cake and allow it to cool for 15 to 20 minutes before slicing to let those layers settle and the flavors meld just right.
How to Serve Chocolate Peanut Butter Earthquake Cake Recipe
Garnishes
Want to take your presentation to the next level? Sprinkle some crushed peanut butter cups or chopped peanuts on top for an extra crunch and visual appeal. A dusting of powdered sugar or a drizzle of melted chocolate can also add a lovely finishing touch that invites everyone to dig in.
Side Dishes
This cake pairs beautifully with a scoop of vanilla or coffee ice cream, which cuts through the richness while complementing the chocolate and peanut butter flavors. Fresh berries or a spoonful of whipped cream can add a bright, fruity contrast for a balanced dessert experience.
Creative Ways to Present
Serve slices of the cake on rustic wooden boards for a cozy, homey vibe or stack small squares in a clear glass trifle dish layered with extra frosting and peanut butter cups for a dramatic, shareable dessert centerpiece. You can even offer mini versions in cupcake liners for a delightful party treat.
Make Ahead and Storage
Storing Leftovers
Wrap any leftover cake tightly with plastic wrap or store it in an airtight container. It will keep well in the refrigerator for up to 4 days, and the flavors tend to deepen when chilled, making each bite taste even better the next day.
Freezing
This cake freezes wonderfully. Slice it before freezing and wrap each piece individually, or cover the whole cake tightly with foil and plastic wrap. Frozen cake can last up to 3 months. When you’re ready to enjoy, thaw overnight in the refrigerator for the best texture.
Reheating
For a warm and gooey slice, reheat portions in the microwave for 15 to 30 seconds, depending on your microwave’s strength. This brings back that fresh-from-the-oven feel, especially when served with ice cream or a drizzle of warm chocolate sauce.
FAQs
Can I use homemade chocolate cake instead of a cake mix?
Absolutely! A homemade chocolate cake can add a personal touch, but the cake mix keeps things simple and foolproof. Just be sure your batter is slightly on the thick side to support the frosting pockets during baking.
What if I’m allergic to peanuts?
You can substitute peanut butter with almond butter or sunflower seed butter for a similar texture and flavor twist. Just be mindful the taste will shift, but it will still be deliciously rich and creamy.
Do I have to use cream cheese in the frosting?
Cream cheese gives the frosting a tangy balance and creamy texture that pairs beautifully with peanut butter. You can experiment with just butter and peanut butter, but the frosting won’t have quite the same light fluffiness or flavor depth.
Why does the cake not fully bake through sometimes?
If the center jiggles too much after baking, your oven temperature might be off or the pan size may vary. Check with a toothpick if unsure; it should come out with moist crumbs but not raw batter. Baking a bit longer in 5-minute increments often fixes it.
Can I make this cake in advance for a party?
Definitely! The Chocolate Peanut Butter Earthquake Cake Recipe actually benefits from sitting a few hours or overnight to let flavors meld. Just bake it the day before, store it covered in the fridge, and take it out about 30 minutes before serving for the perfect soft, rich dessert.
Final Thoughts
If you want to wow your friends and family with a dessert that’s both beautifully indulgent and surprisingly simple, the Chocolate Peanut Butter Earthquake Cake Recipe is your go-to option. It’s a celebration of two classic flavors in every luscious bite, combining ease of preparation with show-stopping results.

Ingredients
Chocolate Cake
- 1 chocolate fudge cake mix (plus ingredients needed to prepare as per package instructions)
Peanut Butter Frosting
- 1/2 cup butter
- 8 ounces cream cheese, softened
- 1/2 cup peanut butter
- 1/2 teaspoon vanilla extract
- 3 1/2 to 4 cups powdered sugar
Toppings
- 1/2 cup chocolate chips
- 1 cup chocolate peanut butter cups, halved
Instructions
- Preheat Oven: Set your oven to 350°F (175°C) to get it ready for baking the cake.
- Prepare Cake Mix: Prepare the chocolate fudge cake mix according to the package directions. Pour the batter into a lightly greased 9×13 inch cake pan. Do not bake yet; set aside for assembly.
- Make Peanut Butter Frosting: Melt the butter on the stovetop until bubbly. In a mixing bowl, beat the melted butter with softened cream cheese until smooth. Add peanut butter and vanilla extract, continuing to beat until fully combined. Gradually add the powdered sugar and beat until the frosting becomes light, fluffy, and well incorporated.
- Assemble Cake: Spoon generous dollops of the peanut butter frosting evenly over the unbaked chocolate cake batter in the pan. Scatter chocolate chips and halved peanut butter cups over the top for added texture and flavor.
- Bake: Place the assembled cake in the preheated oven and bake for 45 to 55 minutes, or until the cake center is only slightly jiggly, indicating it is just set but still moist.
- Cool and Serve: Allow the cake to cool for 15 to 20 minutes before slicing. Serve warm, optionally with ice cream for an extra delicious indulgence.
Notes
- Do not bake the cake batter before adding the frosting; the frosting cooks into the cake as it bakes.
- The center should remain slightly jiggly to ensure moistness; overbaking can dry the cake.
- Using softened cream cheese will make the frosting blend more smoothly.
- For best results, use quality chocolate peanut butter cups and chocolate chips.
- This cake is best served warm for a gooey texture but can also be enjoyed chilled.
