Ingredients

Scale

Cupcakes

  • 12 regular-size glass or ceramic marbles
  • 1 box Betty Crocker™ Super Moist™ Devil’s Food Cake Mix
  • Water, vegetable oil and eggs called for on cake mix box

Frosting

  • 1 cup butter, softened
  • 4 cups powdered sugar
  • 3 tablespoons milk
  • 1 teaspoon vanilla extract
  • Red or pink food color, as needed
  • Candy sprinkles, optional

Instructions

  1. Prepare pan: Heat oven to 350°F. Place paper baking cups in each of 30 regular-size muffin cups. Position one marble in each muffin cup between the paper baking cup and muffin pan so that the paper cups take on a heart shape.
  2. Make batter: Prepare the cake batter according to the instructions on the box, using water, vegetable oil, and eggs as directed. Fill each prepared cup about two-thirds full with batter.
  3. Bake cupcakes: Bake for 14 to 15 minutes or until the tops of cupcakes bounce back when touched and a toothpick inserted in the center comes out clean. Remove from oven and cool completely on a cooling rack.
  4. Prepare frosting: In a large bowl, beat the softened butter, powdered sugar, milk, and vanilla extract using an electric mixer on high speed for 3 to 4 minutes until the frosting is light and fluffy. Add red or pink food coloring to achieve the desired shade.
  5. Frost and decorate: Spread the frosting on the cooled cupcakes with a knife or pipe it using a decorating bag fitted with a plain tip. Top with candy sprinkles if desired.

Notes

  • Use glass or ceramic marbles that are clean and food-safe to shape the cupcakes into hearts.
  • Ensure cupcakes are completely cooled before frosting to prevent melting.
  • Adjust the amount of food coloring gradually to avoid overly intense color.
  • For a dairy-free version, substitute butter with a plant-based alternative and ensure powdered sugar is vegan-friendly.
  • Remove marbles carefully after baking—do not eat or swallow.
