How to Make Reese’s Peanut Butter Earthquake Cake Step by Step
Step 1: Prepare the Baking Dish
Preheat your oven to 350°F (175°C).
Grease a 9x13-inch glass baking dish well to prevent sticking.
Step 2: Make the Chocolate Cake Batter
Prepare the chocolate cake mix according to the package instructions.
Pour the prepared batter evenly into the greased baking dish.
Step 3: Prepare the Peanut Butter Filling
In a large mixing bowl, beat the softened cream cheese and melted butter together until smooth and creamy.
Add the peanut butter and vanilla extract, then continue mixing until fully combined.
Step 4: Add the Powdered Sugar
Gradually mix in the powdered sugar one cup at a time.
The mixture will become thick, fluffy, and creamy.
Step 5: Layer the Filling
Spoon dollops of the peanut butter mixture all over the top of the chocolate cake batter.
Do not stir or mix it into the cake batter. The layers will swirl naturally as the cake bakes.
Step 6: Add the Chocolate and Candy
Sprinkle the chocolate chips evenly over the top.
Scatter the halved mini Reese’s Peanut Butter Cups across the cake for extra gooey chocolate-peanut butter flavor.
Step 7: Bake Until Gooey and Set
Bake for 45 to 55 minutes, or until the center is mostly set but still slightly soft and gooey.
The top will crack and swirl beautifully as it bakes, creating that classic earthquake cake look.
Step 8: Cool Slightly and Serve
Allow the cake to cool slightly before serving.
Serve warm for the ultimate gooey chocolate and peanut butter experience.
Expert Tips
- Do not overbake the cake if you want a gooey center.
- Use full-fat cream cheese for the richest texture.
- Serve warm with vanilla ice cream for an extra indulgent dessert.
- Freeze the Reese’s cups briefly before baking to help them hold their shape.
- Store leftovers covered so the cake stays soft and moist.
How to Store and Reheat It
Store leftovers tightly covered at room temperature for up to 2 days or refrigerate for up to 5 days.
Warm individual slices in the microwave for a few seconds before serving to bring back the gooey texture.
What to Serve With
This rich dessert pairs perfectly with vanilla ice cream, whipped cream, cold milk, or hot coffee.
A drizzle of chocolate syrup or melted peanut butter also makes an extra delicious finishing touch.
Frequently Asked Questions
Can I use crunchy peanut butter?
Yes, though creamy peanut butter gives the smoothest filling texture.
Can I make this ahead of time?
Absolutely. The flavors become even richer after resting for several hours.
Why is it called an earthquake cake?
As the cake bakes, the creamy filling creates cracks, swirls, and uneven pockets throughout the cake, giving it an “earthquake” appearance.
Can I add extra toppings?
Definitely. Chopped peanuts, caramel drizzle, or extra chocolate chips all work wonderfully.
