Ingredients

Scale

Cupcake Batter

  • 2 cups superfine sugar
  • 4 large eggs
  • 0.75 cups canola oil
  • 2 teaspoons pure vanilla extract
  • 1.25 cups fresh water
  • 1 tablespoon espresso powder
  • 2 cups unbleached all-purpose flour
  • 3.4 ounces devil’s food instant pudding mix
  • 0.75 cups unsweetened cocoa powder
  • 2 teaspoons baking powder
  • 0.5 teaspoon baking soda
  • 1 teaspoon salt

Chocolate Ganache

  • 12 ounces bittersweet chocolate
  • 1 cup full-fat coconut milk (can) or heavy cream, shaken well before opening
  • 1 tablespoon unsalted butter

Filling

  • 1 stick unsalted butter (at room temperature)
  • 1 cup shortening
  • 1 teaspoon LorAnn Oils Marshmallow Flavor
  • 1 pound powdered sugar
  • 1 tablespoon meringue powder
  • 0.25 teaspoon salt
  • 2 tablespoons water (add as needed to thin)

Decoration

  • Green colored beads for garnish

Instructions

  1. Preheat and Prepare Pans: Preheat oven to 350°F. Spray 3 mini bundt pans with baking spray and set aside.
  2. Mix Wet Ingredients: In a large bowl, beat together eggs, oil, and superfine sugar until combined.
  3. Dissolve Espresso: Dissolve espresso powder in fresh water, then add to the egg mixture along with vanilla extract. Beat until well combined.
  4. Add Dry Ingredients: Stir in flour, devil’s food pudding mix, cocoa powder, baking powder, baking soda, and salt. Beat until thoroughly combined and smooth.
  5. Fill and Bake: Pour batter about halfway into prepared mini bundt pans. Bake for 18 to 20 minutes, or until a toothpick inserted into the center comes out clean.
  6. Cool Cupcakes: Remove from oven and let cool in the pans for 5 minutes. Then turn out onto wire racks and cool completely.
  7. Prepare Chocolate Ganache: Combine bittersweet chocolate, coconut milk (or heavy cream), and unsalted butter in a bowl. Microwave on HIGH for 1 minute, stir, then continue heating and stirring in 15-second intervals until the ganache is smooth and fully melted.
  8. Dip Cupcakes: Dip cooled cupcakes into the ganache and place them back onto wire racks to set the chocolate coating.
  9. Make Filling: Beat together butter and shortening until light and fluffy. Add marshmallow flavor and meringue powder, then gradually stir in powdered sugar. Beat until fluffy. Add water a little at a time to achieve desired piping consistency.
  10. Core Cupcakes: Use a cupcake or apple corer to remove the center from each cupcake, creating room for filling.
  11. Fill Cupcakes: Fill a pastry bag fitted with your choice of tip with the marshmallow filling. Pipe the filling into the center of each cupcake, allowing it to overflow slightly for a magical effect.
  12. Decorate: Garnish the filled cupcakes with green colored beads to resemble cauldron magic.
  13. Alternative Ding Dongs Style: Use a long, thin decorating tip to fill cupcakes from the bottom instead of coring from the top.

Notes

  • Superfine sugar helps to achieve a smoother batter but can be substituted with granulated sugar blended briefly in a food processor if needed.
  • Ensure the mini bundt pans are well greased to avoid sticking.
  • Allow cupcakes to cool fully before dipping in ganache for best coating adherence.
  • The marshmallow filling can be stored covered in the refrigerator for up to 3 days.
  • Sprinkle green colored beads immediately after filling to ensure they stick well.
  • Ding Dongs filling method is ideal if you prefer to keep the cupcake tops intact for appearance.
  • Espresso powder enhances the chocolate flavor but can be omitted if desired.
