🧾 Ingredients

Cake Base:

  • 1 box chocolate cake mix (plus eggs, oil, and water as listed on box)

Earthquake Layer:

  • ½ cup butter, melted
  • 8 oz cream cheese, softened
  • ½ cup peanut butter
  • ½ tsp vanilla extract
  • 4 cups powdered sugar
  • ½ cup semi-sweet chocolate chips

šŸ”„ How to Make It

1. Preheat & Prep

Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line with parchment paper.

2. Make the Chocolate Cake

Prepare the chocolate cake mix according to the package instructions. Pour the batter into the prepared baking dish and spread evenly.

3. Create the Earthquake Layer

In a separate bowl, beat together the melted butter, cream cheese, peanut butter, and vanilla extract until smooth and creamy. Gradually mix in the powdered sugar until thick and fluffy.

4. Add the Magic

Drop spoonfuls of the peanut butter mixture on top of the chocolate cake batter. Gently swirl with a knife—don’t overmix; you want dramatic, crackly streaks.

5. Finish & Bake

Sprinkle the chocolate chips evenly over the top. Bake for 40–45 minutes, or until the edges are set but the center is still gooey (like a lava cake). It will puff, crack, and swirl—don’t worry, that’s the signature look!
