What You’ll Need

Gather these simple ingredients for your delightful Dark Chocolate Cupcakes with Peanut Butter Marshmallow Fluff:

1 cup all-purpose flour
1 cup granulated sugar
1/2 cup unsweetened cocoa powder
1/2 teaspoon baking soda
1/2 teaspoon baking powder
1/4 teaspoon salt
1/2 cup unsalted butter, melted
2 large eggs
1 teaspoon vanilla extract
1/2 cup buttermilk
1 cup peanut butter marshmallow fluff
1 cup powdered sugar
1/2 cup unsalted butter, softened
1/4 cup peanut butter
1-2 tablespoons milk (for consistency)

Let’s Make It Together

Preheat your oven to 350°F (175°C) and line a cupcake pan with liners. The enticing scent of chocolate will soon fill your kitchen!
In a medium mixing bowl, whisk together the flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt until well combined. Set aside and admire the rich mixture.
In a separate large bowl, combine the melted butter, eggs, vanilla extract, and buttermilk. Mix until smooth and creamy.
Slowly add the wet ingredients to the dry ingredients, gently mixing until just combined. Be careful not to over-mix, as we want our cupcakes to be tender!
Fill each cupcake liner halfway with batter—it’s like a cozy little bed waiting for a special surprise.
Add a spoonful of delicious peanut butter marshmallow fluff right into the center of each liner, then cover with more batter until they are about two-thirds full. The fluff is going to create such a delightful surprise when you take a bite!
Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted in the center comes out clean. While they bake, enjoy the tempting aroma filling your home.
Let the cupcakes cool in the pan for about 5 minutes before transferring them to a wire rack to cool completely.
For the frosting, in a large bowl, beat together the softened butter, peanut butter, and powdered sugar. Add 1-2 tablespoons of milk to achieve the desired consistency, mixing until it’s creamy and decadent.
Once the cupcakes are cooled, frost them generously with the creamy peanut butter frosting. Take a moment to enjoy the colors and textures—you’ve created something beautiful!

Delicious Variations to Try

Chocolate Chip Delight: Add a handful of semi-sweet chocolate chips to the batter for a double chocolate experience. Who can say no to more chocolate?
Nutty Banana Burst: Mix in mashed ripe bananas into the batter for a lovely fruity twist that pairs beautifully with the peanut butter.
Minty Fresh: Add a few drops of mint extract to the frosting for a refreshing mint-chocolate flavor that’s perfect for the cooler months.
Decadent Caramel Drizzle: Drizzle some caramel sauce over the frosted cupcakes just before serving for a rich, indulgent touch.
