Servings: 7 cupcakes



  • 1/4 C unsalted butter softened
  • 1/2 C granulated sugar
  • 2 large egg whites
  • 3/4 tsp McCormick pure vanilla extract
  • 1/8 tsp salt
  • 1 tsp baking powder
  • 1 C cake flour
  • 6 Tbsp milk
  • 16 McCormick green food color
  • 1 drop McCormick blue food color


  • 1/2 C unsalted butter
  • 4 C powdered sugar
  • 3/4 tsp McCormick Vanilla extract
  • 2-3 Tbsp water
  • 14 drops McCormick green food color
  • 1 drop McCormick blue food color


  • Preheat oven to 350°F. Prepare a muffin pan with 7 liners.
  • In the bowl of a stand mixer, cream butter. Mix in sugar, followed by egg whites and vanilla. Add salt, baking powder and cake flour. Slowly add milk, mixing until the batter is smooth. Finally, add food coloring, mixing well until no streaks remain. Using a large cookie scoop, add one scoop to each prepared liner, roughly 2/3 full. Bake for 18-20 minutes or until cupcakes are domed and a toothpick inserted comes out clean. Cool on a wire rack.
  • Prepare frosting in a large bowl or stand mixer. Cream butter until fluffy, mix in powdered sugar, vanilla and 1 Tbsp water at a time until desired consistency is reached. Divide frosting in half. Tint half of the frosting with food coloring. Add each frosting color to one pastry bag fit with a piping tip, carefully placing each color next to each other. Pipe cupcakes. Serve immediately or store in an airtight container.
  • Alternately cupcakes may be swirled by hand, if a piping bag is unavailable, using a spoon or knife.


Alternately, white box cake mix and jar frosting may be used with the following amounts:
-for the cake 1/2 tsp green and 4 drops blue McCormick food coloring
-for the frosting, tint half of the jar with 1 tsp green and 4 drops blue McCormick food coloring.
