What is an Earthquake Cake?

An earthquake cake is a type of cake that features a crumbled or cracked top layer that creates a “quake” effect when you cut into it. The combination of a chocolate cake base and a creamy, gooey peanut butter layer makes it especially delicious and a visual treat. The “earthquake” part comes from the fact that when the cake is baked, the filling often sinks into the chocolate cake, leaving behind cracks and indentations that look like the aftermath of a seismic event.

Reese’s Peanut Butter Earthquake Cake takes this concept to the next level by incorporating Reese’s Peanut Butter Cups and chocolate chips, creating a decadent dessert that will wow anyone who sees it.

History of Earthquake Cake

The “earthquake cake” is a modern invention that has become popular in the United States, especially in Southern kitchens. It’s believed to have originated from a desire to make a cake that’s easy to prepare but looks and tastes impressive. The “quake” part was likely inspired by the cracked appearance the cake takes on after baking. This simple, no-fuss recipe allows home bakers to create a dessert that looks complicated, yet it only requires a few basic ingredients. Over time, people have adapted the basic earthquake cake recipe, adding different ingredients like nuts, peanut butter, and candy bars.

  • Crowd-Pleasing: This cake is perfect for every occasion. Whether you’re hosting a dinner party, attending a potluck, or just treating yourself, Reese’s Peanut Butter Earthquake Cake is sure to please everyone.
  • Layered Texture: The cake has an incredibly satisfying texture, with the cake’s soft, moist base and the creamy, peanut butter filling creating a delicious contrast. The chocolate chips and peanut butter cups provide that perfect crunch that complements the smooth filling.

Ingredients:

Here’s what you’ll need for this delicious dessert:

  • 1 box chocolate cake mix (plus ingredients as listed on the box to prepare)
  • 1/2 cup butter, melted
  • 8 oz cream cheese, softened (you can use full-fat cream cheese for a richer taste)
  • 1 cup powdered sugar
  • 1/2 cup peanut butter (use creamy peanut butter for best results)
  • 1 1/2 cups mini chocolate chips (or regular-sized chips if you prefer)
  • 1/2 cup Reese’s Peanut Butter Cups, chopped (or you can use Reese’s Pieces for a different twist)

Step-by-Step Instructions:

Step 1: Preheat the Oven

Begin by preheating your oven to 350°F (175°C). This temperature is ideal for creating a cake that is moist and fluffy on the inside, while developing a golden, slightly crispy top. Grease and flour a 9×13-inch baking dish to prevent the cake from sticking during the baking process.

Step 2: Prepare the Cake Base

Start with your chocolate cake mix. Follow the instructions on the box to prepare the cake batter. This typically involves mixing the cake mix with eggs, water, and oil (or butter). Make sure all ingredients are well combined, and the batter is smooth and lump-free.

Once the batter is ready, pour it into the prepared baking dish. Use a spatula to spread it evenly, ensuring that the batter covers the bottom of the dish.

Step 3: Make the Peanut Butter Layer

In a separate bowl, take the softened cream cheese and beat it with an electric mixer until it is smooth and creamy. Add in the powdered sugar and peanut butter, and continue mixing until the mixture is fully incorporated. The consistency should be thick, yet spreadable.

This peanut butter filling will be the “earthquake” layer that sinks into the cake while baking, creating that signature marbled effect. Spoon the peanut butter mixture over the top of the chocolate cake batter, and use a spatula to gently spread it out. Be sure to leave a few parts of the cake batter exposed, as you want the mixture to swirl into the cake and not just sit on top.

Step 4: Add the Toppings

Now for the fun part: the toppings! Sprinkle the mini chocolate chips evenly over the peanut butter layer, making sure every corner is covered. Then, add the chopped Reese’s Peanut Butter Cups, spreading them evenly over the surface.

This is where you can get creative. You can add additional toppings like more chocolate chips, Reese’s Pieces, or even crushed nuts if you want a bit more crunch.

Step 5: Bake the Cake

Place the cake in the preheated oven and bake it for about 35 to 40 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs attached. The cake will rise, and the top will form cracks, creating the “earthquake” effect. Don’t worry if the top sinks slightly as it bakes; this is perfectly normal and part of the magic.

While the cake is baking, the peanut butter layer will sink into the chocolate cake batter, creating a gooey, creamy center. The chocolate chips and peanut butter cups will melt slightly and form a delicious, rich topping.

Step 6: Cool and Serve

Once the cake is baked, remove it from the oven and let it cool in the pan for about 20 minutes. This will help the cake set and make it easier to cut.

After it has cooled, slice the cake into generous portions and serve it as-is, or add a scoop of vanilla ice cream or a dollop of whipped cream for extra indulgence.


Serving Suggestions:

  • With Ice Cream: Reese’s Peanut Butter Earthquake Cake is rich and decadent on its own, but serving it with a scoop of vanilla ice cream takes it to the next level. The cold, creamy texture of the ice cream balances out the richness of the cake.
  • Drizzled with Chocolate Sauce: If you’re a chocolate lover, add a drizzle of chocolate sauce or caramel sauce over the cake just before serving. This adds an extra layer of sweetness and makes it look even more decadent.
  • As a Party Treat: This cake is ideal for serving at parties or holiday gatherings. It’s easy to cut into squares, and it’s sure to be a crowd-pleaser. For an added touch, garnish the top with extra peanut butter cups or even a sprinkle of sea salt.

Variations and Customization:

While Reese’s Peanut Butter Earthquake Cake is delicious as-is, there are plenty of ways to put your own spin on it:

  • Peanut Butter Cups Variation: Use Reese’s Pieces or any other peanut butter-flavored candy instead of the mini Reese’s Peanut Butter Cups. You can even use peanut butter M&Ms for a unique twist.
  • Nutty Version: If you love the crunch of nuts, feel free to add chopped peanuts, pecans, or walnuts into the batter or as an additional topping.
  • Healthier Option: If you’re looking for a slightly healthier version of this cake, try using a low-fat cream cheese and opt for a sugar-free cake mix. While it won’t be quite the same as the original, it’ll still have that rich peanut butter flavor.
  • Frosting: For an even more decadent cake, you can frost the top with a peanut butter frosting or chocolate ganache. This will make it extra special, especially if you’re serving it for a celebration.

Storage and Leftovers:

If you have leftovers, store the cake in an airtight container at room temperature for up to 3 days. If you want to extend the freshness of the cake, store it in the refrigerator. However, make sure to bring it to room temperature before serving for the best flavor and texture.

This cake can also be frozen for up to 3 months. To freeze, slice the cake into individual portions, wrap each piece tightly in plastic wrap, and then store it in a freezer-safe container. When ready to enjoy, thaw at room temperature.


Conclusion:

Reese’s Peanut Butter Earthquake Cake is the perfect blend of rich chocolate, creamy peanut butter, and crunchy sweetness. It’s simple to make, even easier to eat, and guaranteed to impress anyone you serve it to. Whether you’re hosting a dinner party, preparing a holiday treat, or just indulging in a little bit of comfort food, this cake is sure to become a favorite.
