Put butter in a stand mixer and turn on high and let whip for 15 min., occasionally scraping sides to make sure all butter is incorporated. Don't skip this step.
After butter is whipped and fluffy start adding the powdered sugar, continuing to whip.
Intermittenly add pink champagne as well. I needed 4 tbsps. of champagne for the right consistency, but you can eyeball this.
Continue to whip and add 1-2 drops of red or pink food coloring.
Turn of mixer and fill a piping bag or ziploc bag with frosting.
Cut off about 1 1/2 inch from one corner and use to pipe frosting onto cupcakes in spiral fashion as seen in photos.
Decorate as desired.
