How to Make Reese’s Chocolate Peanut Butter Cup Earthquake Cake
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with cooking spray or butter.
Step 2: Prepare the Cake Batter
In a large bowl, prepare the chocolate cake mix according to package instructions. Typically, this involves adding oil, eggs, and water. Whisk until smooth. Pour the batter into the greased baking dish and spread evenly.
Step 3: Make the Frosting
In another bowl, beat together cream cheese, butter, peanut butter, and vanilla extract until smooth. Gradually add powdered sugar, mixing until thick and creamy.
Step 4: Assemble the Cake
Spread the frosting over the cake batter in the dish. Sprinkle with chocolate chips and halved Reese’s, pressing them gently into the frosting.
Step 5: Bake the Cake
Bake in the preheated oven for 45-50 minutes, or until a toothpick inserted in the center comes out clean. Be careful not to overbake!
Step 6: Cool and Serve
Let the cake cool completely on a wire rack. Once cooled, slice and serve with a scoop of vanilla ice cream for an extra delightful treat.

Drizzle with Sauce
- Add a drizzle of chocolate or caramel sauce on top of each slice for an extra layer of sweetness and visual appeal.
Fresh Fruit Addition

How to Perfect Reese’s Chocolate Peanut Butter Cup Earthquake Cake
To ensure your Reese’s Chocolate Peanut Butter Cup Earthquake Cake turns out perfectly every time, follow these helpful tips.
- Use room temperature ingredients: Make sure your cream cheese and butter are softened before mixing. This helps create a smooth frosting that spreads easily.
- Don’t overmix: When combining the cake mix and wet ingredients, mix just until everything is combined. Overmixing can lead to a dense cake texture.
- Check doneness carefully: Insert a toothpick in the center; if it comes out clean or with a few moist crumbs, your cake is done. Avoid overbaking for best results.
- Cool completely before slicing: Allowing the cake to cool fully ensures that it holds its shape when cut and prevents the frosting from melting off.
- Store properly: Keep any leftovers in an airtight container at room temperature for up to three days or refrigerate for longer freshness.
Best Side Dishes for Reese’s Chocolate Peanut Butter Cup Earthquake Cake
Pairing side dishes can elevate your dessert experience. Here are some excellent options to serve alongside your cake.
- Vanilla Ice Cream: A classic choice that adds creaminess and balances the rich flavors of the earthquake cake.
- Chocolate Mousse: A light and airy dessert that complements the dense chocolate flavor of the cake.
- Fruit Salad: A mix of seasonal fruits provides freshness that contrasts beautifully with the sweet, rich cake.
- Milkshakes: Thick chocolate or peanut butter milkshakes create a fun pairing that enhances the overall indulgence.

Common Mistakes to Avoid
When making the Reese’s Chocolate Peanut Butter Cup Earthquake Cake, it’s easy to make some common mistakes. Here are a few to watch out for:
- Skipping the cooling step: Allowing the cake to cool completely is essential for the best texture. If you skip this, the frosting may melt and make a mess.
- Overmixing the batter: Mixing too much can lead to a dense cake. Mix just until combined for a light and fluffy texture.
- Not measuring ingredients accurately: Using incorrect measurements can alter the outcome of your cake. Always use standard measuring cups and spoons.
- Using cold ingredients: Cold cream cheese or butter can result in lumpy frosting. Make sure all ingredients are at room temperature before mixing.
