Ingredients You’ll Need
The beauty of Chocolate Peanut Butter Earthquake Cake is that it uses simple, familiar ingredients, yet delivers bold flavor and sensational texture. Each component brings something crucial—don’t be tempted to skimp!
- Chocolate fudge cake mix (15.25 oz): The shortcut foundation that guarantees a moist, chocolatey base every time.
- Large eggs (3): Essential for setting the cake and making it rich and tender.
- Vegetable oil (½ cup): Gives the cake its extra-moist, tender crumb.
- Water (1 cup): Helps bring all the cake batter ingredients together seamlessly.
- Creamy peanut butter (½ cup): Delivers velvety texture and that signature nutty flavor in every bite.
- Cream cheese, softened (8 oz): The creamy backbone for our gooey peanut butter filling.
- Unsalted butter, softened (½ cup): Adds extra richness and smoothness to the peanut butter layer.
- Powdered sugar (2 cups): Sweetens and thickens the peanut butter cream for perfect “crater” effect.
- Vanilla extract (1 teaspoon): Balances and brightens the sweetness of the filling.
- Semi-sweet chocolate chips (½ cup): Creates melty pools of chocolate on top—don’t skip these!
- Peanut butter chips (½ cup): Boosts that peanut butter experience and adds flair to each slice.
- Chopped peanuts (½ cup, optional): Provides a salty, crunchy topping—add only if you love a little crunch.
How to Make Chocolate Peanut Butter Earthquake Cake
Step 1: Preheat and Prep
Start by preheating your oven to 350°F. Lightly grease a 9×13-inch baking dish so nothing sticks later (extra insurance for easy serving), and set it aside. This is your blank canvas for all the magic to follow!
Step 2: Make the Chocolate Cake Layer
Grab a large mixing bowl and prepare the chocolate cake batter according to your box’s instructions—combine the cake mix, eggs, oil, and water. Give it a good whisk until it’s smooth and lump-free. Pour the batter evenly into your prepared baking pan, smoothing the top with a spatula so every bite is perfectly even.
Step 3: Mix the Peanut Butter Cream Filling
In a separate bowl, beat together the softened cream cheese and unsalted butter until they’re completely smooth and fluffy. Add the powdered sugar, vanilla extract, and creamy peanut butter, mixing until creamy, thick, and dreamy. This is where the “earthquake” starts—a totally gooey, irresistible filling!
Step 4: Drop and Top
Using a big spoon, drop hearty dollops of the peanut butter mixture all over the top of your chocolate cake batter. Resist the temptation to swirl! The fun comes in letting these dollops sink and scatter naturally during baking, creating the signature look and texture of Chocolate Peanut Butter Earthquake Cake. Sprinkle the chocolate chips, peanut butter chips, and (if using) chopped peanuts generously over the entire surface.
Step 5: Bake and Cool
Slide your filled pan into the oven and bake for 40–45 minutes. You’re looking for set edges and a slightly gooey, jiggly center—it will finish setting as it cools. The contrasting textures are what makes this dessert addictive! Let it cool at least a little before serving to get the perfect gooey slice.
How to Serve Chocolate Peanut Butter Earthquake Cake
Garnishes
This cake is already a statement, but you can make it extra special with a scoop of vanilla ice cream, a drizzle of warm fudge, or a scatter of extra mini chocolate chips on top. A dusting of powdered sugar also looks beautiful for parties without hiding those glorious swirls.
Side Dishes
A cool glass of milk or a steaming mug of coffee pairs perfectly, balancing out the richness. Fresh strawberries or sliced bananas offer a lovely, light contrast if you want a side of fruit.
Creative Ways to Present
Serve Chocolate Peanut Butter Earthquake Cake slightly warm in individual ramekins for a molten-cake vibe, or cut it into small squares and skewer with fruit for a playful dessert platter. For potlucks, bake and serve directly from the pan—it’s part of the cake’s charm!
Make Ahead and Storage
Storing Leftovers
If you somehow have any left, tightly wrap the pan or transfer slices to an airtight container. Chocolate Peanut Butter Earthquake Cake keeps in the fridge for up to four days and gets even gooier and more irresistible each time you warm it up.
Freezing
Want to save some for a rainy day? Cool the cake completely, then wrap individual slices in plastic and place in a freezer bag. It will hold well in the freezer for up to two months—just thaw overnight in the fridge before enjoying.
Reheating
For that freshly baked gooeyness, zap a slice in the microwave for about 20 seconds or warm in a 300°F oven for a few minutes. This brings back the melty chocolate and creamy pockets—pure comfort in every bite!
FAQs
Can I use a different cake mix flavor?
Absolutely! While chocolate is the classic base for Chocolate Peanut Butter Earthquake Cake, you can try dark chocolate, devil’s food, or even a brownie mix for a fun twist. Just keep the general proportions the same.
Is there a way to make this more peanut buttery?
If you want even more peanut butter punch, double up on the peanut butter chips or swirl a few extra tablespoons of creamy peanut butter right on top before baking. You could even layer roasted peanuts inside the batter for extra crunch.
Do I need to chill the cake before serving?
Not at all! This cake is best enjoyed slightly warm when the filling and chips are gooey and luscious. If you’ve stored it in the fridge, just microwave a slice briefly to recapture that fresh-out-of-the-oven magic.
Can I make this cake gluten free?
Yes, just swap in your favorite gluten-free chocolate cake mix, and ensure your other ingredients (like chocolate and peanut butter chips) are certified gluten-free. The rest of the process and textures should work just as beautifully!
What makes it an “Earthquake” cake?
The signature look comes from dropping dollops of the peanut butter mixture onto the chocolate batter without swirling. As it bakes, the filling sinks and the cake rises, creating cracks, crevices, and gooey marbled pockets—just like the earth shifting!
