Ingredients

Cupcakes

  • 3/4 cup vegetable oil
  • 3.9 oz instant chocolate fudge pudding mix
  • 1 cup sour cream
  • 4 eggs
  • 1 tsp vanilla extract
  • 1/2 cup milk
  • 1 cup chopped walnuts
  • 1/4 tsp sea salt

Frosting

  • 2 cups heavy cream
  • 1/2 cup confectioners’ sugar
  • 1/3 cup instant chocolate pudding mix

Filling

  • 1 1/2 cups marshmallow fluff

Toppings

  • Mini marshmallows
  • Extra chopped walnuts
  • Sprinkles

Instructions

  • Preheat oven to 350°F (175°C). Line two cupcake pans with cupcake liners.
  • In a large bowl, whisk together cake mix, pudding mix, and sea salt.
  • Add eggs, sour cream, vegetable oil, vanilla, and milk. Mix until smooth and fully combined.
  • Fold in chopped walnuts.
  • Divide batter evenly among cupcake liners, filling each about 3/4 full.
  • Bake for 17–19 minutes or until a toothpick inserted comes out clean. Cool completely.
  • For the frosting, whip heavy cream with powdered sugar until soft peaks form. Add pudding mix and continue whipping until thick and pipeable.
  • Core the center of each cupcake and fill with a spoonful of marshmallow fluff.
  • Pipe frosting over each cupcake.
  • Finish with mini marshmallows, extra walnuts, and sprinkles.

Notes

  • Add mini chocolate chips to the batter for extra texture.
  • Chill the frosting 10 minutes before piping for best stability.
  • Use a cupcake corer or small knife to fill cupcakes cleanly.
