INGREDIENTS You Need for This

This Reeses Peanut Butter Cup Earthquake Cake ingredient list is SHORT but mighty! Here’s the rundown:

1 box (15.25 oz) chocolate cake mix (plus ingredients called for on the box, usually eggs, oil, and water)
1 cup sour cream. The secret to epic Reeses Peanut Butter Cup Earthquake Cake is using FULL-FAT sour cream instead of the low-fat stuff! It adds richness and moisture that you just can’t get otherwise.
1 cup peanut butter (creamy or chunky, your call!)
1 cup powdered sugar
8 oz cream cheese, softened
1 teaspoon vanilla extract
1 cup (about 6 oz) mini Reeses Peanut Butter Cups, chopped. You’ll find the best ingredients for this Reeses Peanut Butter Cup Earthquake Cake at your local grocery store, but don’t skimp on the Reeses Peanut Butter Cups!
1/2 cup semi-sweet chocolate chips

This is where we are making some magic happen. The right ingredient will take you from good to Cuba Queen status!

FLAVOR BOOST: Add a pinch of sea salt to the batter. It cuts through the sweetness and makes the chocolate and peanut butter flavors POP.
SOURCING TIP: Buy the block of cream cheese instead of the whipped kind. It blends smoother and has a richer flavor.
BUDGET-FRIENDLY: Store brand powdered sugar works just fine! No need to splurge on this one.
QUALITY UPGRADE: Splurge on the real vanilla extract – trust me, you need the extract to really push the flavor profile of the dish.

Remember to store your ingredients properly. Keep that cream cheese softened but cool. You want it to be as easy to work with as possible.

STEP-BY-STEP INSTRUCTIONS

Okay, flavor adventurers, let’s get down to business! Here’s how to bring this Reeses Peanut Butter Cup Earthquake Cake to life:

Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. Don’t stress – your Reeses Peanut Butter Cup Earthquake Cake is going to be incredible.
Prepare the chocolate cake batter according to the package directions. Pour the batter into the prepared pan.
In a large bowl, beat together the sour cream, peanut butter, powdered sugar, cream cheese, and vanilla extract until smooth and creamy. This is where your Reeses Peanut Butter Cup Earthquake Cake transforms into pure magic. Pro tip for Reeses Peanut Butter Cup Earthquake Cake perfection: make sure your cream cheese is REALLY softened before you start mixing. Otherwise, you’ll end up with lumps.
Drop spoonfuls of the peanut butter mixture over the chocolate cake batter. Swirl the mixtures together using a knife or skewer. Don’t over-mix! You want that beautiful earthquake effect.
Sprinkle the chopped Reeses Peanut Butter Cups and chocolate chips evenly over the top. Feel free to use the big Reeses Peanut Butter Cups – make sure you get the right pieces to balance the flavors.
Bake for 35-40 minutes. In my kitchen, this Reeses Peanut Butter Cup Earthquake Cake takes exactly 37 minutes, but oven temperatures can vary. Your Reeses Peanut Butter Cup Earthquake Cake should look golden brown and a toothpick inserted into the center should come out with moist crumbs.
Let the cake cool completely before cutting and serving. This is the hardest part, I know! This is where most people mess up their Reeses Peanut Butter Cup Earthquake Cake – but not you! Letting it cool completely allows the flavors to meld together and the cake to set properly.
Enjoy your Reeses Peanut Butter Cup Earthquake Cake. While your Reeses Peanut Butter Cup Earthquake Cake is working its magic, grab your camera – this is Instagram gold!

Here are some other things to think about during baking:

TECHNIQUE SECRET: If you want an extra gooey center, underbake the cake by a few minutes.

SENSORY CUES: Your Reeses Peanut Butter Cup Earthquake Cake should smell intensely of chocolate and peanut butter when it’s done.
