Reese’s Peanut Butter Earthquake Cake Ingredients
For the Cake Base
- Chocolate Cake Mix – Provides the cake base for rich chocolate flavor; for a deeper taste, opt for dark chocolate mix.
- Water – Activates the dry ingredients; no substitutions necessary.
- Vegetable Oil – Adds moisture and a soft texture; can replace with melted coconut oil or applesauce for a lighter version.
- Eggs – Binds all ingredients together; use flax eggs for a vegan alternative.
For the Creamy Filling
- Creamy Peanut Butter – Brings a sweet, nutty flavor and luscious texture; can substitute with almond or cashew butter for a different taste.
- Cream Cheese (softened) – Contributes to creaminess and richness; Neufchâtel cheese can be used for a lighter option.
For the Sweet Topping
- Unsalted Butter (melted) – Enhances flavor and moisture; coconut oil works as a dairy-free substitute.
- Powdered Sugar – Sweetens the peanut butter mixture; for a healthier twist, swap with coconut sugar or granulated sugar.

- Reese’s Peanut Butter Cups (chopped) – Adds delightful chocolatey peanut butter bursts to the cake; can omit or replace with chocolate chips if desired.
Step‑by‑Step Instructions for Reese’s Peanut Butter Earthquake Cake
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). While the oven heats up, generously grease a 9×13-inch baking dish with butter or non-stick spray to prevent the cake from sticking. This initial step ensures that your Reese’s Peanut Butter Earthquake Cake bakes evenly and releases easily once done.
Step 2: Prepare the Batter
In a large mixing bowl, combine the chocolate cake mix, water, vegetable oil, and eggs. Use an electric mixer on medium speed for about 2 minutes or until the mixture is smooth and well blended. Gently fold in the chopped Reese’s Peanut Butter Cups and, if desired, chocolate chips to add rich bursts of flavor throughout the cake.
Step 3: Create the Base Layer
Pour half of the prepared batter into the greased baking dish, spreading it evenly to cover the bottom. This chocolatey base sets the stage for your peanut butter filling. Make sure to smooth out the batter with a spatula for an even texture, which will allow the top layer to bake nicely without sinking.
Step 4: Add the Filling
Now, drizzle sweetened condensed milk over the first layer of cake batter, ensuring it covers as much of the surface as possible. Allow the liquid to soak into the batter, creating a deliciously gooey center in your Reese’s Peanut Butter Earthquake Cake. The milk’s sweetness adds richness to the overall dessert.
Step 5: Top Layer of Batter
Carefully pour the remaining half of the chocolate batter on top of the soaked layer, smoothing it gently with a spatula. This layer serves as the final touch, encasing the creamy peanut butter filling and helping create the signature “earthquake” effect during baking. Be gentle to maintain the layers beneath.
Step 6: Bake the Cake
Place the baking dish in the preheated oven and bake for 30-35 minutes. Keep an eye on it, and when a toothpick inserted into the center comes out with moist crumbs (not wet batter), it’s ready to be removed. The outside should be set while the center retains a pleasingly soft texture.
Step 7: Cool and Serve
Once baked, take your Reese’s Peanut Butter Earthquake Cake out of the oven and allow it to cool in the pan for about 10 minutes. If desired, dust with powdered sugar for an elegant finish. After cooling, cut the cake into squares and serve warm, allowing the gooey center to shine through.
