These hot cocoa cupcakes taste like a cozy mug of hot chocolate in cupcake form. Each chocolate cupcake is soft and rich, filled with fluffy marshmallow creme, then finished with swirled marshmallow buttercream and mini marshmallows. They’re a festive, crowd-pleasing dessert that is perfect for the holiday season.
Preheat the oven to 350°F(180°C). Line a 12-cup cupcake pan with liners and set aside. Then whisk the flour, sugar, cocoa powder, baking powder, baking soda, and salt together in a large bowl.
160 grams all purpose flour, 300 grams granulated sugar, 75 grams Dutch-processed cocoa powder, 1 ½ teaspoon baking powder, ¾ teaspoon baking soda, ½ teaspoon salt
In a separate bowl, whisk together the egg, oil, Greek yogurt, and vanilla extract. Pour the mixture into the bowl of dry ingredients and fold with a rubber spatula until just combined. The batter will be thick.
Slowly drizzle in the hot coffee while folding with a rubber spatula. Continue mixing until the batter is thin, smooth, and the ingredients are fully combined.
200 grams brewed coffee
Fill the cupcake liners with the batter, each ⅔-3/4 full. Bake for 15-18 minutes or until a toothpick inserted in the center comes out covered in moist crumbs.
Let the cupcakes cool in the hot pan for 10 minutes, then transfer them to a wire rack to cool completely.
Marshmallow Fluff Frosting
In the bowl of a stand mixer fitted with the paddle attachment, beat the softened butter, vanilla, and salt on medium-high speed until light and fluffy, about 2 minutes.
Scrape down the sides of the bowl, then mix in 1 cup (85 grams) of marshmallow fluff on medium speed until smooth. Reserve the rest of the fluff to fill the cupcakes.
170 grams marshmallow fluff
Add the powdered sugar gradually, in 2-3 additions, mixing on low speed. Scrape down the sides of the bowl after each addition. Once combined, drizzle in the heavy cream increase the speed to medium-high, beating until light and fluffy.
280 grams powdered sugar, 2 tablespoons heavy cream
Assembly
Use a cupcake corer, a piping tip, or a small paring knife to remove the centers of the cupcakes. Fill each with about 1 teaspoon of marshmallow fluff.
Add the buttercream to a piping bag fitted with a round piping tip. Pipe the frosting on top of each cupcake.
Garnish the cupcakes with mini marshmallows or hot cocoa mix and enjoy!
