Ingredients
To make your delicious Reese’s Peanut Butter Earthquake Cake, gather the following ingredients:
For the Cake Batter

- 1 cup water
- 1/2 cup vegetable oil
- 3 large eggs
For the Peanut Butter Layer

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:
1. Mix together the chocolate cake mix, water, vegetable oil, and eggs until well combined.
2. Pour the batter into the prepared baking dish evenly.
Step 3: Make the Peanut Butter Mixture
In a separate bowl:
1. Combine creamy peanut butter, softened cream cheese, melted unsalted butter, powdered sugar, and vanilla extract.
2. Mix until smooth and creamy.
Step 4: Layer the Mixtures
Using a spoon:
1. Drop spoonfuls of the peanut butter mixture over the cake batter randomly.
2. Use a knife to gently swirl the peanut butter mixture into the batter for that earthquake effect.
Step 5: Add Toppings
Sprinkle chopped Reese’s Peanut Butter Cups evenly over the top of the batter for an added crunch and flavor.
Step 6: Bake the Cake
Bake in your preheated oven for about 35-40 minutes. Check doneness by inserting a toothpick into the center; it should come out mostly clean.
Step 7: Cool and Serve
Allow your cake to cool slightly before serving. Enjoy warm or at room temperature for maximum flavor!

How to Perfect Reese’s Peanut Butter Earthquake Cake
Achieving the perfect Reese’s Peanut Butter Earthquake Cake can be simple with a few handy tips. Follow these suggestions to get your cake just right.
-
Use Room Temperature Ingredients: Ensure your eggs and cream cheese are at room temperature for easier mixing and better texture.
-
Don’t Overmix the Batter: Mix just until combined to avoid a dense cake. A few lumps in the batter are okay!
-
Swirl Carefully: When adding the peanut butter mixture, swirl gently to create marbled patterns without completely blending it into the cake base.
-
Check for Doneness: Use a toothpick inserted into the center; it should come out mostly clean. This ensures your cake is perfectly baked without being dry.
-
Let It Cool: Allow the cake to cool slightly before serving. This helps set the layers and makes slicing easier.
-
Store Properly: Keep leftovers in an airtight container at room temperature for up to three days, or refrigerate for longer freshness.

Common Mistakes to Avoid
Baking can be tricky, especially with decadent recipes like Reese’s Peanut Butter Earthquake Cake. Here are some common mistakes to watch out for:
- Not preheating the oven: Skipping this step can lead to uneven baking. Always preheat your oven to 350°F (175°C) before starting.
- Overmixing the batter: This can make the cake dense instead of fluffy. Mix just until the ingredients are combined for the best texture.
- Ignoring ingredient temperature: Using cold ingredients can affect how well they combine. Let your cream cheese and eggs come to room temperature before use.
- Not measuring accurately: Baking is a science. Use proper measuring cups and spoons to ensure accurate ingredient amounts.
- Crowding the pan: If you pack too much batter into the baking dish, it won’t cook evenly. Stick to the recommended size of a 9×13-inch pan.
