Ingredients
To create the perfect Reese’s Peanut Butter Earthquake, you’ll need the following ingredients:
- 1 box chocolate cake mix: The foundation of this dish, with its rich cocoa flavor.
- 3 large eggs: Essential for binding and adding moisture.
- 1/2 cup oil: Provides the cake with a tender crumb.
- 1 cup water: Helps in achieving the right cake batter consistency.
- 120 g melted butter: Adds a luxurious richness to the overall flavor profile.
- 225 g softened cream cheese: Infuses the dish with a creamy texture and tangy taste.
- 125 g creamy peanut butter: The star of the show, adding a nutty,, velvety smooth flavor.
- 2.5 ml vanilla extract: Enhances the sweet aromas in the dish.
- 500 g powdered sugar: Sweetens the cream cheese mixture, giving it the perfect consistency.
- 90 g semi-sweet chocolate chips: Contributes delightful bursts of chocolatey goodness.
- 180 g mini peanut butter cups, halved: Provides delightful pockets of peanut butter goodness and a delightful crunch.
Step-by-Step Directions

Preheat your oven to 175°C (350°F) and lightly grease a 23 x 33 cm glass baking dish. This helps prevent the cake from sticking and ensures easy removal later.
In a large mixing bowl, mix the chocolate cake batter according to package instructions, incorporating the specified water, oil, and eggs. Pour evenly into the prepared baking dish, making sure it’s smooth and well-distributed.
In another bowl, beat together the softened cream cheese and melted butter until smooth. This creates a rich mixture that is essential for the dessert’s creamy peanut butter layer. Add the creamy peanut butter and vanilla extract, mixing until combined. Gradually blend in powdered sugar until the mixture is thick and creamy, resembling a luxurious frosting.
Distribute spoonfuls of the peanut butter cream mixture across the surface of the chocolate batter, leaving swirls visible. This step adds beautiful marbling that enhances both presentation and flavor.
Scatter the semi-sweet chocolate chips and halved mini peanut butter cups over the top. Feel free to press some into the batter gently for an inviting look and to ensure they stay well incorporated while baking.
Bake for 45 to 55 minutes, or until edges are set and the top is cracked. Allow to cool slightly before serving warm, or cool completely for neat slices. Either way, the warm and inviting aroma wafting from your kitchen will surely beckon everyone nearby!
Tips & Tricks
For an even richer flavor, consider using homemade chocolate cake rather than a boxed mix. Moreover, if you prefer a little more crunch, add some chopped peanuts to the top before baking, or even swirl in some extra creamy peanut butter for a more indulgent experience. Always err on the side of slightly underbaking if you enjoy a fudgier texture!
Serving Suggestions & Pairings
Reese’s Peanut Butter Earthquake is best served warm or at room temperature. Pair it with a scoop of vanilla ice cream or generous dollops of whipped cream to complement the chocolatey, peanut buttery goodness. It’s perfect for birthday parties, potlucks, or even as a cozy dessert for movie nights with family. Top it off with chocolate syrup drizzle for an extra touch of indulgence!
