When it comes to indulgent desserts, few can compete with the rich, gooey delight of a Chocolate Peanut Butter Earthquake Cake. This crowd-pleasing creation is exactly what its name suggests — a fudgy, luscious cake packed with layers of chocolate, peanut butter, and a surprise “earthquake” of cookie chunks and peanut butter cups erupting through every bite. If you’re looking for a show-stopping dessert that combines classic flavors with a texture-packed punch, this recipe is guaranteed to satisfy your chocolate and peanut butter cravings in the most decadent way possible.
What Is Earthquake Cake?
Earthquake Cake is a fun and descriptive name for a type of layered cake that’s stuffed full of mix-ins and chunks that break through the batter, creating a “cracked” or “earthquake” effect on the surface once baked. The cake’s top looks like it has been dramatically split open by pockets of peanut butter cups, cookie pieces, or other sweet treats baked inside.
This particular version features the iconic pairing of chocolate and peanut butter — a match made in dessert heaven — combining creamy peanut butter, melted chocolate, and crunchy peanut butter cups, all embedded in a moist chocolate cake. The result is a dessert that’s rich, gooey, and texturally exciting.
Why Chocolate and Peanut Butter?
Chocolate and peanut butter have a timeless, irresistible chemistry. The rich, bittersweet flavor of chocolate complements the salty, nutty creaminess of peanut butter, creating a perfect balance that is both comforting and indulgent. This cake elevates that pairing by incorporating peanut butter in both the batter and filling, and by scattering chopped peanut butter cups throughout, it adds little pockets of gooey, melty goodness.
Ingredients You’ll Need
To make a Chocolate Peanut Butter Earthquake Cake, here’s the typical ingredient list:
- 1 box chocolate cake mix (plus ingredients called for on box, usually eggs, oil, and water)
- 1 cup creamy peanut butter
- 1 (8 oz) package cream cheese, softened
- 1 cup powdered sugar
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 cup chopped peanut butter cups (like Reese’s)
- 1 cup crushed chocolate sandwich cookies (like Oreos)
- Optional: chocolate ganache or frosting for topping
Time and Yield
- Prep Time: 20 minutes
- Bake Time: 45–50 minutes
- Total Time: About 1 hour 10 minutes
- Yield: Serves 12–15 generously
Step-by-Step Instructions
1. Preheat Oven and Prepare Pan
Preheat your oven to 350°F (175°C). Grease and flour a 9×13-inch baking dish, or line it with parchment paper for easy removal.
2. Make the Cake Batter
Prepare the chocolate cake batter according to the instructions on the box (usually eggs, oil, and water). Pour about half of the batter into the prepared pan and spread evenly.
3. Prepare the Peanut Butter Cream Cheese Layer
In a mixing bowl, beat the softened cream cheese and peanut butter until smooth and creamy. Add powdered sugar, eggs, and vanilla extract, then mix until fully combined.
4. Layer the Cake
Spoon the peanut butter cream cheese mixture evenly over the first layer of chocolate cake batter. Then sprinkle chopped peanut butter cups and crushed chocolate sandwich cookies generously over the cream cheese layer. Finally, dollop and spread the remaining chocolate cake batter over the top. Don’t worry if the topping layer is uneven—this creates the signature “earthquake” texture when baked.
5. Bake
Bake for 45–50 minutes until the top is set and a toothpick inserted near the center comes out mostly clean (a few moist crumbs are okay due to the gooey layers).
6. Cool and Serve
Allow the cake to cool completely in the pan. This dessert tastes best when chilled or at room temperature. Optionally, drizzle with chocolate ganache or spread a creamy frosting on top before slicing.
