What Kind of Chocolate Should I Use?

How To Make the Peanut Butter Chocolate Cupcakes

Step 1: Prepare the Chocolate Cupcake Batter

Preheat your oven to 350°F (175°C). Line a muffin tin with 12 cupcake liners.
In a large bowl, whisk together 1 cup flour, 1/2 cup unsweetened cocoa powder, 1 tsp baking powder, 1/2 tsp baking soda, and 1/4 tsp salt.

Step 2: Combine the Wet Ingredients

In a separate bowl, mix 1/2 cup granulated sugar, 1/2 cup brown sugar, 2 eggs, 1/3 cup vegetable oil, 1/2 cup milk, and 1 tsp vanilla extract. Mix until smooth.

Step 3: Blend Wet and Dry, Add Hot Water

Slowly mix the dry ingredients into the wet until fully combined. Stir in 1/2 cup boiling water. The batter will be thin—this is normal.

Step 4: Fill and Bake

Fill each cupcake liner about 2/3 full. Bake for 18–20 minutes or until a toothpick inserted comes out clean. Let cool completely.

Step 5: Core and Fill

Use a small knife or cupcake corer to remove the centers. Fill each hole with 1 tsp of creamy peanut butter and 1/2 tsp caramel sauce.

Step 6: Make the Peanut Butter Frosting

Beat 1/2 cup softened unsalted butter and 3/4 cup creamy peanut butter until fluffy. Slowly add 1 1/2 cups powdered sugar and beat until smooth. Pipe or spread onto cooled, filled cupcakes.

Step 7: Garnish and Drizzle

Top with chopped mini peanut butter cups. Melt 1/4 cup chocolate chips and drizzle over each cupcake.

Best Way to Store Peanut Butter Chocolate Cupcakes

Store these cupcakes in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate for up to 5 days. Let them come to room temperature before serving so the frosting softens. They also freeze well—just wrap individually and freeze for up to 2 months.

Frequently Asked Questions

Can I make these cupcakes in advance?
Yes! Bake and freeze the cupcakes without frosting. Thaw and frost before serving.

What if I don’t like caramel?
You can skip the caramel or swap it for extra peanut butter or a dollop of chocolate ganache.

Can I use a cake mix instead of making the batter from scratch?
Sure! Use a chocolate cake mix and follow the box directions, then proceed with the filling and frosting.

Can I use natural peanut butter?
It’s best to use creamy, no-stir peanut butter for consistent texture in both the filling and frosting.

Do I need to refrigerate them because of the frosting?
If it’s warm where you are, refrigerate. Otherwise, they can sit out safely for a day or two.
