Ingredients

Scale
  • Cupcake Batter:
  • 1 box white cake mix
  • ½ cup vegetable oil
  • 4 egg whites
  • 1¼ to 1¾ cups grape soda
  • ½ to ¾ package grape Jello (divided use)
  • Grape food coloring (optional)
  • Grape Frosting:
  • 2 sticks salted butter, softened
  • 1 tsp vanilla extract
  • 1 tsp salt
  • 4 cups powdered sugar
  • 1 tbsp half-and-half or whole milk
  • 2 tbsp grape soda
  • Remaining grape Jello
  • Grape food coloring (optional)
  • Optional Decorations:
  • Purple sanding sugar
  • Paper straws (cut into thirds)

Instructions

  1. Preheat oven to 350°F (175°C). Line or grease a 24-cup muffin tin.
  2. In a large bowl, mix cake mix, vegetable oil, egg whites, and grape soda until well incorporated.
  3. Add ½–¾ of the grape Jello and stir to combine. Add grape food coloring if desired for a bolder purple color.
  4. Fill each cupcake liner ⅔ full and bake for 18–20 minutes, or until a toothpick inserted into the center comes out clean.
  5. Remove from oven and cool cupcakes completely on a wire rack before frosting.
  6. To make the frosting, beat the softened butter until light and fluffy (about 2 minutes).
  7. Mix in vanilla extract, salt, and the remaining grape Jello.
  8. In a small bowl, combine grape soda and half-and-half or milk.
  9. Gradually add the powdered sugar to the butter mixture, alternating with small amounts of the soda/milk blend. Beat until frosting is fluffy and holds stiff peaks.
  10. Add grape food coloring if desired, one drop at a time, until the desired color is achieved.
  11. Pipe frosting onto cooled cupcakes. Garnish with purple sanding sugar and insert a paper straw for a fun, soda-fountain look.

Notes

  • Use gel food coloring for a more intense purple hue without thinning the frosting.
  • Don’t overmix the frosting—stop once stiff peaks form to keep the texture stable.
  • Refrigerate frosted cupcakes if not serving within 24 hours, and let them come to room temperature before serving.
  • These cupcakes are a great make-ahead dessert for parties and potlucks.
