Ingredients You’ll Need

Getting the ingredients right is key to nailing this recipe, and luckily it calls for simple pantry staples that work together beautifully. Each ingredient adds its own magic—whether it’s the moistness of the cake, the luscious creaminess of peanut butter, or the crunch of the chocolate cups, everything plays a crucial role in creating that unforgettable texture and flavor.

  • 1 box (15.25 oz) chocolate cake mix: Choose your favorite devil’s food cake mix for a rich chocolate base that sets the stage perfectly.
  • 1 cup water: Room temperature water helps the batter come together smoothly without compromising texture.
  • 1/2 cup vegetable oil: Adds moistness and tenderness to the cake; melted coconut oil is a tasty alternative for a subtle twist.
  • 3 large eggs: Bringing eggs to room temperature ensures better incorporation and fluffier cake layers.
  • 1 cup creamy peanut butter: Go for regular creamy peanut butter to keep that silky, rich texture without separation issues.
  • 1 cup powdered sugar: Sweetens and thickens the peanut butter mixture to create that luscious filling.
  • 1/2 cup melted butter: Salted butter shines here for balancing sweet and salty notes, but unsalted works too.
  • 1 teaspoon vanilla extract: Small but mighty, this brings warmth and depth to the overall flavor.
  • 1 cup Reese’s peanut butter cups: Chopped into small pieces to scatter those bursts of peanut butter and chocolate bliss.
  • 1/2 cup semi-sweet chocolate chips: Adds pockets of gooey, melty chocolate perfectly paired with peanut butter.

How to Make Reeses Peanut Butter Earthquake Cake

Step 1: Prepare the Chocolate Cake Batter

Start by combining the cake mix, water, vegetable oil, and eggs in a large bowl. Beat with a mixer until the batter is smooth and well blended. The chocolate base is the foundation of this cake’s rich flavor, and beating it properly ensures a moist and tender crumb.

Step 2: Make the Peanut Butter Filling

In a separate bowl, mix together the creamy peanut butter, powdered sugar, melted butter, and vanilla extract until smooth and creamy. This luscious filling is what makes the Reeses Peanut Butter Earthquake Cake truly special—it melts slightly during baking and forms tasty pockets that peek through the chocolate layers.

Step 3: Layer the Batter and Filling

Pour about a third of the chocolate batter into your greased baking pan. Dollop half of the peanut butter filling over this, then sprinkle half the Reese’s peanut butter cups and semi-sweet chocolate chips. Repeat layering with the remaining batter and peanut butter filling, topping with the rest of the chopped peanut butter cups and chips. This layering technique is what creates the “earthquake” of flavors and textures.

Step 4: Bake to Perfection

Bake the cake in a preheated oven at 350°F (175°C) for about 40 to 45 minutes, or until a toothpick inserted near the center comes out mostly clean with a few moist crumbs. The rich peanut butter chunks will melt into the cake, giving it that signature ooey-gooey texture you’re after.

Step 5: Cool and Serve

Allow the cake to cool in the pan for at least 30 minutes before slicing. This rest time helps the layers set just right so every bite holds together beautifully while still oozing creamy peanut butter charm.

Garnishes

To elevate your serving, consider sprinkling a light dusting of powdered sugar or drizzling some melted chocolate on top. For an extra touch of elegance and peanut power, crushed Reese’s peanut butter cups or chopped roasted peanuts create irresistible texture and visual appeal.

Side Dishes

This cake is indulgent enough to stand on its own, but a dollop of whipped cream or a scoop of vanilla bean ice cream beautifully balances the richness. If you want to add a fruity contrast, fresh raspberries or sliced strawberries provide a wonderful bright note that cuts through the sweetness.

Creative Ways to Present

If you’re sharing this cake at a party, slice it into small squares and serve it on a festive platter with mini spoons. You could also turn slices into decadent ice cream sandwiches or layer it with peanut butter mousse for a stunning layered dessert parfait that wows any crowd.

Make Ahead and Storage

Storing Leftovers

You can store leftover Reeses Peanut Butter Earthquake Cake covered tightly at room temperature for up to two days, or in the refrigerator for up to five days. Just make sure it’s well wrapped to keep moisture in and prevent odors from other foods from sneaking in.

Freezing

This cake freezes wonderfully! Wrap it snugly in plastic wrap and aluminum foil to protect it from freezer burn. It will keep for up to three months, letting you enjoy the Reeses Peanut Butter Earthquake Cake anytime you want a sweet escape.

Reheating

When you’re ready to enjoy frozen cake, thaw it in the refrigerator overnight. You can warm individual slices in the microwave for 15-20 seconds to bring back that melty peanut butter sensation, or let it come to room temperature for a more balanced texture.

FAQs

Can I use natural peanut butter instead of creamy peanut butter?

Natural peanut butter isn’t recommended because it tends to separate and can affect the texture of the filling. The creamy, regular peanut butter keeps the filling smooth and holds together better during baking.

Can I substitute homemade chocolate cake for the cake mix?

Absolutely! Homemade chocolate cake works just as well if you prefer from-scratch baking. Just make sure it’s moist and sturdy enough to handle the peanut butter filling and mix-ins.

What type of pan is best for this cake?

A 9×13-inch baking pan is ideal for this recipe. It gives the cake enough room to spread evenly and bake thoroughly with the layers of peanut butter filling and chocolate chips.

Can I double this recipe for a larger crowd?

Yes, doubling the ingredients and using a larger baking dish or two pans works perfectly. Just keep an eye on baking time, as it may need to increase depending on pan size.

Is it possible to make this cake vegan or dairy-free?

It would take some careful substitutions since the cake mix, eggs, butter, and peanut butter cups all contain animal products or dairy. There are vegan peanut butter cups and dairy-free options, but texture and taste may vary quite a bit.

Final Thoughts

Making the Reeses Peanut Butter Earthquake Cake is like inviting pure happiness into your kitchen. The blend of chocolate, peanut butter, and chopped peanut butter cups creates a dessert that’s as fun to make as it is to eat. Whether you’re treating yourself or impressing friends, this cake delivers a big, delicious party in every bite. Go ahead, grab those ingredients, and bake up this joyful masterpiece—you won’t regret it!

Ingredients

Scale

Cake Ingredients

  • 1 box (15.25 oz) chocolate cake mix (devil’s food recommended)
  • 1 cup water (room temperature)
  • 1/2 cup vegetable oil (or melted coconut oil)
  • 3 large eggs (room temperature)

Peanut Butter Filling

  • 1 cup creamy peanut butter (regular, not natural)
  • 1 cup powdered sugar (broken up, no need to sift)
  • 1/2 cup melted butter (salted or unsalted)
  • 1 teaspoon vanilla extract

Mix-ins and Toppings

  • 1 cup Reese’s peanut butter cups (minis, chopped into quarters)
  • 1/2 cup semi-sweet chocolate chips (or milk chocolate)

Instructions

  1. Prepare the Cake Batter: In a large mixing bowl, combine the chocolate cake mix, water, vegetable oil, and eggs. Mix until smooth and well incorporated, ensuring no lumps remain. The batter should be thick but pourable.
  2. Make the Peanut Butter Filling: In a separate bowl, mix together the creamy peanut butter, powdered sugar, melted butter, and vanilla extract. Stir until the mixture is smooth and creamy, forming a thick peanut butter layer.
  3. Layer the Ingredients: Preheat the oven to 350°F (175°C) and grease a 9×13 inch baking dish. Pour half of the chocolate cake batter into the dish and spread evenly. Drop spoonfuls of half the peanut butter mixture over the batter, then sprinkle with half of the chopped Reese’s peanut butter cups and semi-sweet chocolate chips.
  4. Add the Second Layer: Pour the remaining cake batter over the peanut butter and candy layer, spreading gently to avoid mixing. Add the remaining peanut butter mixture in spoonfuls over the top, followed by the remaining chopped peanut butter cups and chocolate chips. The batter and filling will ripple and swirl, creating an ‘earthquake’ effect.
  5. Bake the Cake: Place the baking dish in the preheated oven and bake for 35-40 minutes, or until a toothpick inserted into the center comes out mostly clean with a few moist crumbs. Avoid overbaking to keep the gooey texture.
  6. Cool and Serve: Allow the cake to cool at room temperature for at least 30 minutes to set the peanut butter layers. Slice into squares and serve as is or with a scoop of vanilla ice cream for extra indulgence.

Notes

  • Use regular creamy peanut butter, not natural, to prevent separation and ensure smooth filling.
  • If you prefer a sweeter cake, substitute semi-sweet chocolate chips with milk chocolate chips.
  • Room temperature eggs and water help the batter mix evenly for a better texture.
  • For easier cutting, chill the cake slightly after it cools to firm up the layers.
  • Store leftovers covered in the refrigerator for up to 4 days; bring to room temperature before serving.
