How to Make It

Prepare the cupcakes according to the package or recipe instructions. Let them cool completely before decorating.

In a large bowl, beat the softened butter until creamy. Gradually add powdered sugar, one cup at a time, mixing well after each addition.
Add the vanilla extract and 1 tablespoon of milk at a time until the frosting reaches your desired consistency.

Spread or pipe a generous swirl of buttercream frosting on each cupcake.

Use black gel icing or piping chocolate to draw a wavy string across the frosting.

Place M&Ms along the “string” to resemble colorful Christmas lights. Alternate colors for a festive look.
