I made the Super Moist White Cake recipe from, Gail Herbest, and then frosted it with this really fluffy buttercream frosting. It tastes fantastic and it's really fluffy and soft. A bit too soft for creating roses, but edge piping is perfect. This is going to be a winner!
With a mixer, beat the butter for 1 minute. Then add the powdered sugar, Package of Dream Whip, salt, whipping cream and the vanilla. Mix on low speed until all combined then on high speed for 4-5 minutes.
