Peanut Butter Earthquake Cake Ingredients
For the Cake Base
• Chocolate Cake Mix – A dark chocolate cake mix offers a richer depth of flavor.
• Water – Just use tap water; it helps keep the batter moist.
• Vegetable Oil – Adds moisture and tenderness; melted coconut oil can be a tasty alternative.
• Eggs – Acts as a binder; flaxseed meal can be swapped for a vegan option.
For the Peanut Butter Filling
• Creamy Peanut Butter – The star of the show! Almond butter works if you need a nut-free version.
• Cream Cheese (softened) – Provides a rich creaminess; mascarpone can be used for a different texture.
• Unsalted Butter (melted) – Enhances flavor and moisture; margarine is a suitable substitute.
• Powdered Sugar – For sweetness and a smooth filling; granulated sugar can be used but will be grainier.
• Vanilla Extract – Elevates the flavor profile; almond extract offers a delightful twist.
For Assembly
• Reese’s Peanut Butter Cups (chopped) – These treats add bursts of sweetness throughout the cake; any chocolate candy can be a scrumptious swap.
• Sweetened Condensed Milk – Drizzled for extra moisture and a luscious texture.
• Chocolate Chips – Sprinkled on top for a decadent finishing touch.

Step‑by‑Step Instructions for Peanut Butter Earthquake Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C), and while it warms up, grease a 9×13-inch baking dish to ensure easy removal of your Peanut Butter Earthquake Cake later. Use a non-stick spray or softened butter for best results, as this will create a beautiful, clean edge on your delightful creation.
Step 2: Prepare the Cake Batter
In a large mixing bowl, combine the chocolate cake mix, water, vegetable oil, and eggs. Using an electric mixer, blend these ingredients on medium speed until the mixture is smooth and well combined, about 2 minutes. You’ll know it’s ready when the batter is free of lumps and has a velvety texture, perfect for the base of your Peanut Butter Earthquake Cake.
Step 3: Make the Peanut Butter Mixture
In a separate bowl, mix together the creamy peanut butter, softened cream cheese, melted butter, powdered sugar, and vanilla extract. Use a hand mixer to blend until the mixture is creamy and free of lumps, about 1-2 minutes. This enticing peanut butter filling will add a rich, gooey center to your cake, enhancing its decadent flavor.
Step 4: Assemble the First Layer
Pour half of the chocolate cake batter into your greased baking dish, spreading it evenly with a spatula. Once distributed, drizzle a layer of sweetened condensed milk evenly over the batter to add an extra depth of sweetness and moisture. This step is crucial for achieving that signature earthquake effect in your Peanut Butter Earthquake Cake.
Step 5: Add the Peanut Butter Filling
Carefully drop spoonfuls of the creamy peanut butter mixture over the chocolate batter, ensuring an even distribution. With a knife, gently swirl the peanut butter filling into the batter, creating a marbled effect without fully blending the layers. This will allow those delightful peanut buttery pockets to shine through after baking.
Step 6: Top with Remaining Batter
Now, pour the remaining chocolate cake batter over the peanut butter layer, distributing it evenly. Once covered, sprinkle a generous amount of chocolate chips on top. This not only adds a beautiful touch but also enriches the flavor profile, promising a chocolaty surprise in every bite of your Peanut Butter Earthquake Cake.
Step 7: Bake to Perfection
Place the baking dish in your preheated oven and bake for 35-40 minutes. To check for doneness, insert a toothpick into the center; it should come out with moist crumbs, indicating that your cake is ready. The top will look slightly cracked, signaling the perfect “earthquake” texture that makes this dessert so irresistible.
Step 8: Cool and Serve
Once baked, remove the Peanut Butter Earthquake Cake from the oven and let it cool in the pan for about 10-15 minutes. This resting period allows the cake to set properly and makes slicing easier. Dust the top with powdered sugar for an elegant finish, and serve warm to enjoy the gooey decadence of this family favorite.
How to Store and Freeze Peanut Butter Earthquake Cake
Room Temperature: Store the cake in an airtight container at room temperature for up to 3 days to maintain its deliciously gooey texture.
