Ultra soft Sugar Cookie Bars are frosted with a thick, fluffy layer of buttercream, topped with decorative sprinkles, and baked in a pan for an easy dessert perfect for all occasions!
In a large bowl beat the butter until light and creamy. Add the powder sugar, heavy cream, vanilla, and pinch of salt gradually on low speed until mixed in. Increase mixer to high and beat until very light and fluffy, about 7 minutes. Tip: Beating for a long time is what makes this frosting extremely fluffy. Mix in food coloring, if using.
