Ingredients
- 1 1/4 cups all-purpose flour
- 1/2 cup unsweetened cocoa powder
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 1 teaspoon vanilla extract
- 1 cup buttermilk
- 1/2 cup creamy peanut butter
- 1/4 cup powdered sugar
- 1 cup heavy cream
- 1/2 teaspoon vanilla extract (for frosting)
Directions & Preparation
- Preheat your oven to 350°F (175°C) and line a cupcake pan with paper liners.
- In a medium bowl, whisk together the flour, cocoa powder, baking soda, and salt. Set this mixture aside.
- In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy, about 3-4 minutes.
- Add the vanilla extract and mix well. Gradually add the dry ingredients to the wet mixture, alternating with buttermilk, beginning and ending with the dry ingredients. Mix until just combined.
- Spoon the batter into the prepared cupcake liners, filling each about two-thirds full. Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
- While the cupcakes are baking, prepare the peanut butter filling. In a small bowl, mix the creamy peanut butter with the powdered sugar until smooth and well combined.
- Once the cupcakes are done, remove them from the oven and allow them to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
- When the cupcakes are cool, use a knife or a cupcake corer to create a small hole in the center of each cupcake. Fill each hole generously with the peanut butter mixture.
- For the frosting, whip the heavy cream with the remaining 1/4 cup powdered sugar and 1/2 teaspoon vanilla extract until stiff peaks form.
- Frost the filled cupcakes with the whipped cream topping, and if desired, drizzle extra peanut butter over the top for an added touch.

For make-ahead, prep components separately and assemble just before heating to preserve texture.
