1/2 teaspoon baking soda
1/2 teaspoon baking powder
1/4 teaspoon salt
1/2 cup unsalted butter, melted
2 large eggs

How to Make Dark Chocolate Cupcakes with Peanut Butter Marshmallow Fluff

Preheat your oven to 350°F (175°C) and line a cupcake pan with cupcake liners.
In a large bowl, mix together the flour, granulated sugar, cocoa powder, baking soda, baking powder, and salt until well combined.
In another bowl, combine the melted butter, eggs, vanilla extract, and buttermilk. Stir gently until mixed.
Slowly add the wet ingredients to the dry ingredients, mixing until just combined. Be careful not to overmix; a few lumps are okay!
Fill each cupcake liner about halfway with the batter.
Add a spoonful of peanut butter marshmallow fluff into the center of each cupcake.
Cover the fluff with more batter until the liners are about 3/4 full.
Bake for 18-20 minutes or until a toothpick comes out clean.
Let the cupcakes cool completely in the pan before transferring them to a wire rack.
For the frosting, beat together the softened butter, peanut butter, and powdered sugar until creamy. Add milk as needed for desired consistency.
Frost the cooled cupcakes generously with the creamy peanut butter frosting.

Delicious Variations to Try

Chocolate Chip Surprise: Add a handful of chocolate chips into the batter for an extra gooey texture and flavor.
Nutty Twist: Sprinkle chopped peanuts on top of the frosting for a crunchy contrast.
Zesty Flavor: Incorporate a teaspoon of orange zest into the batter for a bright, refreshing take.
Decadent Frosting Options: Swap out the peanut butter frosting for a chocolate ganache for an indulgent twist.
