How to Make Reese’s Peanut Butter Earthquake Cake
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease your 9×13-inch baking dish to prevent sticking.
Step 2: Prepare the Cake Batter
In a large bowl, combine the chocolate cake mix, water, vegetable oil, and eggs. Mix until everything is well blended. Pour this batter into your prepared baking dish.
Step 3: Make the Peanut Butter Mixture
In another bowl, mix together the creamy peanut butter, softened cream cheese, melted butter, powdered sugar, and vanilla extract. Stir until you achieve a smooth consistency.
Step 4: Combine Layers
Drop spoonfuls of the peanut butter mixture over the top of the cake batter in your baking dish. Use a knife to swirl this mixture gently into the batter to create marbled layers.
Step 5: Add Toppings
Sprinkle the chopped Reese’s Peanut Butter Cups evenly over the surface of the cake batter.
Step 6: Bake Your Cake
Place your baking dish in the preheated oven. Bake for 35-40 minutes or until you can insert a toothpick into the center and it comes out mostly clean.
Step 7: Cool Before Serving
Once baked, allow your cake to cool slightly before cutting. Enjoy it warm or let it reach room temperature before serving.

With Whipped Cream

A Scoop of Ice Cream
- Vanilla or chocolate ice cream provides a cold, creamy counterpoint to the warm cake. It melts slightly, creating a deliciously gooey texture.
Drizzled Chocolate Sauce

How to Perfect Reese’s Peanut Butter Earthquake Cake
To make sure your Reese’s Peanut Butter Earthquake Cake turns out perfectly every time, follow these essential tips.
-
Use Room Temperature Ingredients: Ensure that your cream cheese and eggs are at room temperature for smoother mixing and better texture.
-
Don’t Overmix: Mix just until combined to prevent the cake from becoming dense. Overmixing can lead to a less desirable texture.
-
Swirl Carefully: When swirling the peanut butter mixture into the batter, be gentle. Too much mixing can lose the beautiful layered effect.
-
Check Doneness: Start checking your cake around 35 minutes in; ovens vary and you want it baked just right without being overdone.

Common Mistakes to Avoid
When making Reese’s Peanut Butter Earthquake Cake, it’s easy to make a few common mistakes that can affect the final outcome. Here are some pitfalls to avoid.
- Neglecting to preheat the oven: Always preheat your oven to ensure even baking. Skipping this step can lead to an undercooked or uneven cake.
