How To Make This Peanut Butter Earthquake Cake Recipe with Reese’s
Making this dessert is surprisingly easy.
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C).
Grease a 9×13-inch baking dish or line it with parchment paper for easier cleanup.
Step 2: Prepare the Chocolate Cake
Mix the chocolate cake according to the directions on the package.
Pour the batter evenly into the prepared baking dish.
Do not overfill the pan since the peanut butter layer will be added on top.
Step 3: Make the Peanut Butter Filling
In a large bowl combine:
Softened cream cheese
Melted butter
Peanut butter
Powdered sugar
Beat until smooth and creamy.
The mixture should resemble thick frosting.
Step 4: Create the Earthquake Effect
Drop large spoonfuls of the peanut butter filling all over the chocolate batter.
Do not spread it completely.
The uneven placement creates beautiful swirls while baking.
Step 5: Add Reese’s and Chocolate
Sprinkle:
Chopped Reese’s Peanut Butter Cups
Chocolate chips
Evenly over the top.
If desired, sprinkle chopped peanuts or a pinch of flaky sea salt.
Step 6: Bake
Bake for 40 to 45 minutes.
The center should still look slightly soft.
The surface should have cracks, dips, and bubbling areas.
That’s exactly what creates the earthquake appearance.
Step 7: Cool
Allow the cake to cool for about 30 minutes before cutting.
This helps the filling set while remaining wonderfully gooey.
