How to Make Indulgent Reese’s Chocolate Peanut Butter Cup Earthquake Cake
- Preheat the Oven: Start by preheating your oven to 350°F (175°C). Don’t forget to grease a 9×13 inch baking pan to prevent sticking!
- Prepare the Cake Batter: In a large mixing bowl, combine the chocolate cake mix, water, vegetable oil, and eggs. Mix until well combined and smooth.
- Add Peanut Butter Mixture: In a separate bowl, mix together the creamy peanut butter and powdered sugar until smooth. Drop spoonfuls of this mixture into the cake batter, and gently swirl it in with a knife to create a beautiful marbled effect.
- Incorporate Chocolate Chips and Reese’s: Stir in the chocolate chips and chopped Reese’s Peanut Butter Cups into the batter, making it even more indulgent.
- Pour into Pan: Pour the batter into the prepared baking pan, spreading it evenly with a spatula.
- Bake: Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
- Make Chocolate Sauce: While the cake is baking, prepare the chocolate sauce by combining the milk, cocoa powder, vanilla extract, and salt in a small saucepan over medium heat. Stir until the mixture is smooth and begins to simmer. Remove from heat.
- Add Sauce to Cake: Once the cake is done baking, remove it from the oven and immediately pour the chocolate sauce over the top, spreading it evenly to soak into the cake.
- Cool and Serve: Allow the cake to cool for at least 15 minutes before serving. Enjoy warm or at room temperature for the best experience!
