What You’ll Need

Gather these simple ingredients to create your luscious 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)

How to Make Dark Chocolate Cupcakes with Peanut Butter Marshmallow Fluff

Let’s make it together! Follow these easy steps to create your delicious masterpiece:

Preheat your oven to 350°F (175°C) and line a cupcake pan with cupcake liners.
In a large bowl, mix together the flour, 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. Avoid over-mixing to keep the cupcakes tender.
Fill each cupcake liner about halfway with the batter, making sure not to fill them all the way to the top.
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. The tops should look set and slightly shiny.
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 your desired consistency.
Frost the cooled cupcakes generously with the creamy peanut butter frosting, and enjoy!

Fun Ways to Customize It

Swap the Fluff: Try using chocolate marshmallow fluff for a double dose of chocolatey goodness!
Nutty Add-ins: Toss in some chopped nuts, like crunchy peanuts or walnuts, for extra texture and flavor.
Seasonal Twist: Add a hint of cinnamon or pumpkin spice for a cozy fall variation.
Decoration Delight: Top with melted chocolate or colorful sprinkles to add a festive flair.

Chef Emma’s Helpful Tips

Make Ahead: These cupcakes can be made a day in advance; just store them in an airtight container to keep them fresh.
Sweeter or Softer?: For sweeter frosting, add more powdered sugar, or if you prefer softer frosting, just adjust the milk.
Room Temperature Ingredients: Ensure your eggs and buttermilk are at room temperature for a better batter blend and rise.
Frosting Fun: If you’re short on time, use store-bought frosting to save time without sacrificing taste.
