this Recipe

Ingredients:

• 1 box (18.25 ounces) chocolate cake mix
• 1 cup water
• 1/2 cup vegetable oil
• 3 large eggs
• 1 cup creamy peanut butter
• 1 1/2 cups powdered sugar
• 8 ounces cream cheese, softened
• 1/2 cup butter, softened
• 1 teaspoon vanilla extract
• 1 jar (12 ounces) hot fudge topping
• 1 cup Reese’s Peanut Butter Cups, chopped (about 15-20 cups)

Preparing the Cake Batter

Okay, let’s get started with the base of our amazing Reese’s Peanut Butter Earthquake Cake – the chocolate cake! This is where the magic begins, and trust me, it’s super easy.

1. Preheat your oven to 350°F (175°C). This is crucial! Make sure your oven is properly preheated to ensure the cake bakes evenly. Nobody wants a soggy center!
2. Grease and flour a 9×13 inch baking pan. I like to use a baking spray that already has flour in it, but you can also grease the pan with butter or shortening and then dust it with flour. This prevents the cake from sticking and makes it easy to remove after baking. Trust me, you’ll thank me later.
3. In a large mixing bowl, combine the chocolate cake mix, water, vegetable oil, and eggs. Now, grab your favorite large mixing bowl. Add the dry cake mix first, then pour in the water and oil. Crack in those eggs, and you’re ready to mix!
4. Beat with an electric mixer on medium speed for 2 minutes. Use your electric mixer (handheld or stand mixer, either works great!) and beat the ingredients together on medium speed for a full 2 minutes. This ensures everything is well combined and the batter is nice and smooth. Don’t overmix, though! Overmixing can lead to a tough cake.
5. Pour the batter into the prepared baking pan. Once the batter is smooth and creamy, pour it evenly into the greased and floured 9×13 inch baking pan. Spread it out so it’s nice and even.

Making the Peanut Butter Swirl

Now for the fun part – the peanut butter swirl! This is what gives the cake its signature “earthquake” look and, of course, that irresistible peanut butter flavor. Get ready to get your swirl on!

1. In a separate mixing bowl, combine the peanut butter, powdered sugar, cream cheese, butter, and vanilla extract. Grab another mixing bowl (a medium-sized one will do) and add the creamy peanut butter, powdered sugar, softened cream cheese, softened butter, and vanilla extract. Make sure your cream cheese and butter are softened; otherwise, you’ll end up with a lumpy mixture.
2. Beat with an electric mixer until smooth and creamy. Using your electric mixer again, beat all these ingredients together until they are perfectly smooth and creamy. This might take a few minutes, so be patient. Scrape down the sides of the bowl as needed to ensure everything is well combined.
3. Drop spoonfuls of the peanut butter mixture over the chocolate cake batter. Now, using a spoon, drop spoonfuls of the peanut butter mixture randomly over the top of the chocolate cake batter. Don’t worry about being too precise; the more random, the better!
4. Use a knife or skewer to swirl the peanut butter mixture into the chocolate cake batter. This is where the “earthquake” effect comes in! Take a knife or a wooden skewer and gently swirl the peanut butter mixture into the chocolate cake batter. Don’t overmix; you want to see distinct swirls of peanut butter throughout the cake. The more you swirl, the more marbled the effect will be.

Baking the Earthquake Cake

Almost there! Now it’s time to bake our masterpiece. The aroma that will fill your kitchen is simply divine. Get ready for some serious peanut butter and chocolate goodness!

1. Bake in the preheated oven for 35-40 minutes, or until a wooden skewer inserted into the center comes out with moist crumbs. Place the cake in the preheated oven and bake for 35-40 minutes. To check for doneness, insert a wooden skewer into the center of the cake. If it comes out with moist crumbs attached, the cake is done. If it comes out clean, it might be slightly overbaked, so keep an eye on it.
2. Let the cake cool completely in the pan. Once the cake is baked, remove it from the oven and let it cool completely in the pan. This is important because if you try to frost it while it’s still warm, the frosting will melt. Patience is key!

Frosting and Topping

The final touch! This is where we take our already amazing cake to the next level. Get ready for a decadent explosion of hot fudge and Reese’s Peanut Butter Cups. This is what makes it truly unforgettable.

1. Warm the hot fudge topping according to the jar instructions. Follow the instructions on the jar of hot fudge topping to warm it up. Usually, this involves microwaving it for a short period of time. Make sure it’s nice and warm so it’s easy to pour.
2. Pour the warm hot fudge topping over the cooled cake. Once the cake is completely cooled, pour the warm hot fudge topping evenly over the top. Spread it out so it covers the entire surface of the cake.
3. Sprinkle the chopped Reese’s Peanut Butter Cups over the hot fudge topping. Finally, sprinkle the chopped Reese’s Peanut Butter Cups generously over the hot fudge topping. The more, the merrier! This adds a delicious crunch and that classic Reese’s flavor that we all love.
4. Let the hot fudge topping set slightly before serving. Allow the hot fudge topping to set slightly before serving. This will prevent it from being too runny. You can even pop the cake in the refrigerator for a few minutes to speed up the process.
5. Cut into squares and serve. Now, cut the cake into squares and serve. Get ready for rave reviews! This Reese’s Peanut Butter Earthquake Cake is sure to be a crowd-pleaser.

Tips and Variations

Want to customize your Earthquake Cake? Here are a few ideas:

• Use a different flavor of cake mix. While chocolate is classic, you could also try yellow cake, devil’s food cake, or even a peanut butter cake mix for an extra peanut butter punch!
• Add chocolate chips to the batter. For an even richer chocolate experience, stir in a cup of chocolate chips (milk chocolate, dark chocolate, or semi-sweet) to the cake batter before baking.
• Substitute the hot fudge topping with caramel sauce. If you’re not a fan of hot fudge, caramel sauce is a delicious alternative.
• Add a sprinkle of sea salt. A sprinkle of sea salt over the top of the cake enhances the sweetness and adds a delightful salty-sweet contrast.
• Make it gluten-free. Use a gluten-free chocolate cake mix to make this cake gluten-free. Just be sure to check the labels of all your ingredients to ensure they are gluten-free.

Storage Instructions

If you happen to have any leftovers (which is unlikely!), store the cake in an airtight container in the refrigerator for up to 3 days. The hot fudge topping may harden slightly, but it will still taste delicious!

Enjoy!
