What You’ll Need

Ingredients:

For the Cupcakes:

1 cup all-purpose flour: The base for your cupcake batter. Be sure to measure your flour correctly by spooning it into the measuring cup and leveling it off to avoid using too much flour.
1/2 cup unsweetened cocoa powder: This gives the cupcakes a rich chocolate flavor. Unsweetened cocoa powder is essential for balancing the sweetness of the cupcake with that deep cocoa taste.
1/2 tsp baking powder: Helps the cupcakes rise and gives them a light, fluffy texture.
1/2 tsp baking soda: Also helps with leavening, making sure the cupcakes puff up nicely.
1/4 tsp salt: Enhances the flavor of the cupcakes and balances out the sweetness.
1/2 cup unsalted butter, softened: Adds richness and moisture to the cupcakes. Make sure the butter is softened to room temperature for easy mixing.
1 cup granulated sugar: Provides sweetness to the cupcake batter.
2 large eggs: Helps bind the ingredients together and adds structure to the cupcakes.
1 tsp vanilla extract: Adds a sweet, aromatic flavor to complement the chocolate.
1/2 cup buttermilk: Gives the cupcakes a tender crumb and helps activate the baking soda for a light texture.
1/2 cup hot water: Adds moisture to the batter and helps create a soft, gooey texture inside the cupcakes.

Peanut Butter Lava Center:

1 cup creamy peanut butter: The star ingredient for the lava center. Creamy peanut butter creates the smooth, melt-in-your-mouth filling.
1/2 cup powdered sugar: Adds sweetness to the peanut butter and helps it hold its shape inside the cupcake.

Frosting:

1 cup creamy peanut butter: The base for your frosting. This will give the frosting that delicious, peanut buttery flavor.
1/2 cup unsalted butter, softened: The butter creates a smooth, creamy consistency for the frosting.
1/2 cup powdered sugar: Adds sweetness to the frosting and helps it hold its texture.
1/4 cup heavy cream: Helps thin out the frosting to make it spreadable and creamy.

Garnishing:

Additional mini peanut butter cups: These are used for garnish, adding a cute touch to each cupcake and enhancing the peanut butter flavor.

Step-by-Step Instructions

1: Prepare the Cupcake Batter

Preheat your oven: Start by preheating your oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners or lightly grease the cups with non-stick spray.
Mix the dry ingredients: In a medium bowl, whisk together the flour, cocoa powder, baking powder, baking soda, and salt. Set this bowl aside.
Cream the butter and sugar: In a large bowl, use an electric mixer to cream together the softened butter and granulated sugar until light and fluffy. This will take about 2-3 minutes.
Add the eggs and vanilla: Add the eggs, one at a time, beating well after each addition. Stir in the vanilla extract until fully combined.
Add the buttermilk and dry ingredients: Alternate adding the buttermilk and the dry ingredients to the butter mixture, beginning and ending with the dry ingredients. Mix just until combined after each addition. The batter should be smooth and thick.
Add the hot water: Gradually stir in the hot water. The batter will become thin, but that’s okay – this will make the cupcakes extra moist.

2: Prepare the Peanut Butter Lava Filling

Mix the peanut butter and powdered sugar: In a separate bowl, combine the creamy peanut butter and powdered sugar. Stir until the mixture is smooth and thick. This will be the lava center for the cupcakes.
Shape the peanut butter filling: Roll the peanut butter mixture into small balls, about the size of a walnut, and set them aside on a piece of wax paper or parchment paper.

3: Fill the Cupcakes

Fill cupcake liners halfway: Spoon a small amount of the cupcake batter into each cupcake liner, filling it about halfway full.
Add the peanut butter filling: Gently place one peanut butter ball into the center of each cupcake liner, pressing it down slightly so it’s partially submerged in the batter.
Top with remaining batter: Cover the peanut butter ball with the remaining cupcake batter, making sure it’s completely covered. Don’t overfill the cupcake liners, as the batter will rise during baking.

4: Bake the Cupcakes

Bake the cupcakes: Place the cupcake tin in the preheated oven and bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean (or with just a few moist crumbs). The cupcakes should rise nicely and have a soft, slightly springy texture when touched.
Cool the cupcakes: Once baked, remove the cupcakes from the oven and allow them to cool in the tin for about 5 minutes. Then transfer them to a wire rack to cool completely.

5: Prepare the Peanut Butter Frosting

Cream the peanut butter and butter: In a medium bowl, beat together the creamy peanut butter and softened butter until smooth and fluffy.
Add powdered sugar and cream: Gradually add the powdered sugar, one cup at a time, until the frosting becomes thick and creamy. Stir in the heavy cream and beat until the frosting is smooth and spreadable.

6: Assemble the Cupcakes

Frost the cupcakes: Once the cupcakes have cooled completely, use a piping bag or a spatula to pipe or spread the peanut butter frosting onto each cupcake.
Drizzle with melted chocolate: Melt the chocolate chips in the microwave or using a double boiler, then drizzle the melted chocolate over the frosted cupcakes for an added touch of chocolatey goodness.
Garnish with mini peanut butter cups: Place a mini peanut butter cup on top of each frosted cupcake for a beautiful and delicious garnish.

7: Serve and Enjoy!

Allow the cupcakes to set for a few minutes so the frosting and chocolate drizzle firm up. Once everything has cooled and set, serve your mouthwatering Peanut Butter Cup Lava Cupcakes and enjoy the peanut butter and chocolate goodness in every bite!

Tips for Success

Use room temperature ingredients: For the best texture and even mixing, make sure your butter, eggs, and cream cheese (for the frosting) are at room temperature before you begin.
Be careful not to overmix the batter: Overmixing the cupcake batter can result in dense, tough cupcakes. Mix just until the ingredients are combined to ensure a light, airy texture.
Check for doneness: Oven temperatures can vary, so start checking the cupcakes at around 18 minutes by inserting a toothpick. If it comes out clean or with a few moist crumbs, the cupcakes are done.
Let the cupcakes cool completely: Make sure your cupcakes are completely cool before frosting them. If they’re too warm, the frosting may melt or slide off.
Adjust the lava center: If you want a more gooey lava center, slightly underbake the cupcakes by about 2 minutes. This will give the peanut butter center more time to remain molten.

Variations to Try

Chocolate Lava Filling: For a double chocolate experience, swap out the peanut butter lava filling for a gooey chocolate ganache center. The combination of rich chocolate and peanut butter frosting would be irresistible.
Add Crunch: For some extra texture, add chopped peanuts or crushed peanut butter cups into the cupcake batter for a crunchy surprise.
Banana Peanut Butter Cupcakes: Add mashed bananas to the batter for a delicious banana-peanut butter combination. The banana will keep the cupcakes extra moist!
Mini Lava Cupcakes: If you prefer mini treats, you can scale down the recipe and make mini cupcakes instead of regular-sized ones. Adjust the baking time to 12-15 minutes.

Storing and Reheating

Storing:

At room temperature: Store these cupcakes in an airtight container at room temperature for up to 3 days. The peanut butter frosting will remain soft and creamy.
In the fridge: If you want to keep them fresh for a longer period, store them in the refrigerator for up to 5 days. Allow the cupcakes to come to room temperature before serving for the best texture.

Reheating:

Microwave: For a warm and gooey treat, place the cupcake in the microwave for about 10-15 seconds before serving. The peanut butter center will get soft again, and the frosting will slightly melt for extra deliciousness.

Frequently Asked Questions

Can I freeze these cupcakes?

Yes! You can freeze the cupcakes (without frosting) for up to 3 months. Let them cool completely, then wrap them individually in plastic wrap and place them in a freezer-safe bag. When you’re ready to enjoy them, thaw them at room temperature and frost before serving.

Can I make these cupcakes without the molten peanut butter center?

Absolutely! If you prefer not to have a molten center, you can skip the peanut butter filling and just make a regular chocolate peanut butter cupcake. They will still be delicious with the peanut butter frosting and chocolate drizzle.
