How to Make Decadent Reese’s Peanut Butter Earthquake Cake
Step 1: Preheat and Prepare Baking Dish
Preheat oven to 175°C and lightly grease a 23 x 33 cm glass baking dish.
Step 2: Prepare Cake Batter
Prepare the chocolate cake batter as directed on the package by adding water, oil, and eggs. Mix until smooth and pour into the baking dish.
Step 3: Mix Peanut Butter Cream
In a large bowl, mix softened cream cheese and melted butter until smooth. Add peanut butter and vanilla extract, mix well. Gradually stir in powdered sugar until creamy and thick.
Step 4: Create Swirl Layer

Storage Tips
Once you have enjoyed your decadent Reese’s Peanut Butter Earthquake Cake, you can store any leftover slices at room temperature for up to three days. Simply cover the cake to protect its freshness. If you wish to keep it for a longer period, individually wrap the slices in foil or place them in an airtight container and freeze them for up to two months. When ready to enjoy a slice, you can heat it in the microwave for 10 to 15 seconds to have that warm, fresh-from-the-oven feel. Consider adding an extra drizzle of peanut butter or chocolate chips for an extra indulgent touch.
For a variation on the recipe, you can experiment with almond butter instead of peanut butter or use a gluten-free chocolate cake mix to accommodate dietary preferences. If you run out of cream cheese, mascarpone can be a rich substitute. Additionally, feel free to swap in dark chocolate chips or chopped chocolate bars if that is what you have available. This versatile recipe allows for personalization while still retaining its irresistible combination of chocolate, peanut butter, and Reese’s cups. Whether for a casual gathering or a special celebration, this cake is sure to delight your friends and family with every slice.
Ingredient Substitutions
For a different flavor profile, consider swapping almond butter for peanut butter in this recipe. It will provide a nutty twist that complements the chocolate cake well. Additionally, if you or someone you are baking for has dietary restrictions, you can opt for a gluten-free chocolate cake mix to make this dessert suitable for those needs.
If you happen to run out of cream cheese, you can use mascarpone as a rich and indulgent substitute. The creamy texture of mascarpone will still provide a tangy contrast to the chocolate cake and peanut butter layers. Similarly, if you don’t have semi-sweet chocolate chips on hand, feel free to use dark chocolate chips or chopped chocolate bars as an alternative for the same melty chocolate effect in the cake.
Whether you choose to serve this Reese’s Peanut Butter Earthquake Cake warm or cooled, both ways offer delightful textures and flavors. A warm slice will be gooier and perfect for a comforting dessert, while cooled slices hold their shape well for neater servings. If you have leftovers, simply cool the cake fully, cover it, and store it at room temperature or in the freezer for longer enjoyment.
Serving Suggestions
For a fun and indulgent serving suggestion, try plating slices of the Reese’s Peanut Butter Earthquake Cake with a generous scoop of creamy vanilla ice cream on the side. The warm cake paired with the cold ice cream creates a delightful contrast in temperatures and textures, making every bite a heavenly experience.
To take the presentation up a notch, drizzle each slice of the cake with warm fudge sauce and top it off with a dollop of freshly whipped cream.
