Hot Chocolate Cupcakes

  • 1 1/2 cup unsalted butter
  • 2 cups sugar
  • 4 large eggs
  • 1 tsp vanilla extract
  • 2 cups all-purpose flour
  • 3/4 cup unsweetened cocoa powder
  • 2 ounce hot chocolate mix divided 1 ounce for the batter and 1 ounce for dusting over the cupcakes.
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 1 1/2 tsp salt
  • 1 cup whole milk
  • 1/2 cup canola oil

Creamy Chocolate Frosting (follow the directions and ingredients)

    Homemade Marshmallow Fluff (follow for directions and ingredients)

    • 20 large marshmallows


    • Preheat the oven to 350 degrees.
    • In a mixing bowl beat butter, sugar, vanilla until fluffy. About 3 minutes, scrape down the sides of the bowl.
    • Add eggs one at a time and beat until incorporated.
    • In another bowl add flour, cocoa powder, hot chocolate mix, salt, baking powder and baking soda.
    • Measure milk and oil together in a measuring cup.
    • Alternate adding in the flour mix and the milk and oil mixture to the butter and beat on low.
    • Scrape down the sides and bottom of the bowl and mix until smooth.
    • Line a cupcake pan and fill each cup 3/4 full with batter.
    • Bake for 15 minutes or until the cupcakes are not jiggly in the center. Do not over bake.
    • Let the cupcakes cool, then remove a small hole in the center using a little spoon.
    • Add marshmallow fluff into a piping bag (or a ziplock and cut the corner) and fill the center of the cupcakes. You can always make the marshmallow fluff the day before or use store-bought.
    • Using a cookie scooper, scoop a ball of frosting over the top of the cupcake.
    • Add a large marshmallow ontop and dust with hot chocolate powder.


    Do not over bake the cupcakes. Every oven is different so check them after 10 minutes and then another 5 minutes to ensure they're done.
    You can use store bought marshmallow fluff if it's easier.
