Ensure your cupcakes are fully cooled before decorating. Pre-cut the mini marshmallows in half.

Attach your decorating tip (Wilton #32 recommended but optional) to the disposable bag and fill it with the red frosting.

Pipe a ring of red frosting onto the top of each cupcake.

Place the halved mini marshmallows around the frosting ring.

Fill the circle with more red frosting, piping upwards and swirling to create the peaked shape of Santa’s hat.

Place a halved mini marshmallow at the peak as the pom-pom.

Place decorated cupcakes in the refrigerator for a few minutes to allow the frosting to firm up before serving.
