What You’ll Need

Gather these simple ingredients to create your own cozy confection:

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 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. This is the gooey surprise!
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 this indulgent treat!

Variations & Creative Twists

There are so many delightful ways you can customize these cupcakes to suit your taste:

Add a Crunch: Fold in some chopped nuts, like roasted peanuts or pecans, into the cupcake batter for added texture.
Extra Richness: Swap half of the all-purpose flour for whole wheat flour for a heartier bite that still remains beautifully moist.
Flavor Infusion: Try adding a splash of espresso or instant coffee granules to the batter for a deeper chocolate flavor.
Top It Off: Drizzle a little melted chocolate on top of the frosting for a decadent finishing touch that enhances the chocolate flavor.

Chef Emma’s Helpful Tips

Make-Ahead: These cupcakes store well in an airtight container for up to three days at room temperature. Feel free to bake them ahead of time!
Ingredient Swaps: If you’re out of buttermilk, you can use regular milk with a splash of vinegar as a substitute. It’ll give you the same tender texture.
Easy Slicing: To easily frost the cupcakes, use a piping bag for a beautiful presentation. If you don’t have one, a zip-top bag with the corner cut off works just as well.
Storage Suggestions: To keep your cupcakes perfectly moist, store them in an airtight container and separate layers with parchment paper to avoid sticking.
