Ingredients
For the Cupcakes:
- 1 box of your favorite cake mix (plus required ingredients as per package instructions)
For the Rainbow Buttercream:
- 1 cup unsalted butter, softened
- 4 cups (16 ounces) powdered sugar
- ¼ cup heavy whipping cream
- 1 teaspoon clear vanilla flavoring
- Food coloring gel in assorted colors
Directions
- Prepare Cupcakes: Start by preparing the cupcakes according to the package instructions. This usually involves mixing the dry cake mix with water, oil, and eggs. Pour the batter into cupcake liners in a muffin tin and bake as directed. Allow the cupcakes to cool completely after baking, as applying frosting to warm cupcakes can cause the buttercream to melt.
- Make Buttercream: In a large bowl, beat the softened butter until smooth and creamy. Gradually add the powdered sugar, followed by the cream and vanilla, and continue beating until the mixture is fluffy and light. This creates a smooth, spreadable buttercream that’s perfect for piping.
- Color the Buttercream: Divide the buttercream evenly into six different bowls. Using food coloring gels, tint each portion a different color of the rainbow. The intensity of the color can be adjusted according to preference; more drops will result in a more vibrant color.
- Assemble the Frosting: Lay out a piece of plastic wrap and carefully stripe each color of buttercream in thick lines next to each other. Roll the plastic wrap up tightly and snip one end. Insert this into a piping bag fitted with a 1M tip, ensuring that the open end allows the colors to merge as they are piped.
- Decorate: Pipe the rainbow frosting onto each cooled cupcake, creating a beautiful swirl that showcases all the colors. Start from the outer edge of the cupcake and work inwards, lifting off at the center to create a peak.
