Cupcakes
  1. Preheat your oven to 350°F (175°C). Place cupcake liners in your cupcake pans.
  2. Combine the cake mix, eggs, vegetable oil, buttermilk, sour cream, and vanilla extract in a large bowl.
  3. Mix the ingredients until well combined, ensuring the batter is smooth.
  4. Fill each cupcake liner until it is ¾ full with the batter.
  5. Bake the cupcakes for 15-20 minutes or until a toothpick inserted into the center comes out clean.
  6. Cool the cupcakes completely on a wire rack before filling and frosting.
Filling
  1. In the bowl of your mixer fitted with the paddle attachment or in a large bowl for use with your handheld electric mixer, whip butter until smooth.
  2. Add marshmallow creme and mix until smooth. Slowly ADD powdered sugar until thoroughly combined.
  3. Drizzle in 5 tablespoons heavy cream and whip until smooth. Place the filling into a piping bag. Set aside.
Ganache Frosting
  1. Place chocolate in a heat-proof bowl.
  2. Heat the whipping cream in a small saucepan over medium heat until it simmers gently. Do not let it come to a rapid boil.
  3. Pour over the chocolate. Let it sit for 3 minutes.
  4. Whisk until the chocolate has melted and is thoroughly combined.
Assemble the Cupcakes
