How to Make Chocolate Peanut Butter Earthquake Cake

1. Prepare the Chocolate Cake Base

1. Preheat oven to 350°F (175°C).

2. Grease a 9×13 inch baking dish.

3. In a bowl, mix the chocolate cake mix with oil, water, and eggs.

4. Pour the batter evenly into the prepared dish.

2. Make the Peanut Butter Cream Cheese Swirl

1. In a mixing bowl, beat the softened cream cheese.

2. Add melted butter and peanut butter, mixing until smooth.

4. Drop spoonfuls of this mixture all over the chocolate batter.

3. Add the Toppings

Sprinkle evenly over the top:

• Mini chocolate chips

• Peanut butter chips

• Chopped peanuts (optional)

Use a knife to gently swirl the layers — not too much, just enough to create marbled patterns.

4. Bake

Bake for 40–45 minutes, or until the edges are set but the center is still slightly gooey.
(Earthquake cakes are supposed to look cracked and messy — that’s the beauty!)

How to Serve
