How to Make Perfect Cupcakes with Rainbow Frosting

  1. Preheat Oven: Start by preheating your oven to 350°F. While it warms up, line your muffin tins with colorful cupcake liners to set the stage for your delightful treats.

  2. Cream Butter & Sugar: In the bowl of a stand mixer, cream together the softened butter and sugar until the mixture is smooth and fluffy. This step creates the lovely airiness that your cupcakes will need!

  3. Add Wet Ingredients: Incorporate egg whites, the oil, and vanilla into the creamed butter and sugar. Mix this together until just combined, then pour in the milk and continue mixing until smooth.

  4. Incorporate Dry Ingredients: Gradually add the salt, baking powder, and flour. Mix until everything is combined, scraping down the sides of the bowl as needed to ensure even mixing.

  5. Bake: Spoon the cupcake batter into the prepared liners, filling them about ½ to ⅔ full. Bake in the preheated oven for about 14 minutes, or until the tops are golden and a toothpick inserted comes out clean. Allow them to cool completely.

  6. Make Frosting: In a clean mixer bowl, beat the softened butter, vanilla, and salt together. Gradually add half of the powdered sugar, mixing until mostly combined. Then, add the remaining sugar and milk, beating until fluffy and smooth.

  7. Color the Frosting: Divide the frosting into separate bowls. Add food coloring to each bowl to create your vibrant rainbow hues. Mix well until you achieve the desired colors.

  8. Decorate: Once the cupcakes are completely cool, spread a mound of white frosting on top. Use the colored frosting to pipe beautiful rainbow designs on each cupcake. Top with mini marshmallows to create whimsical “clouds.”

Optional: Add rainbow sprinkles for extra color and crunch!
