  • 1 box of white or vanilla boxed cake mix , mixed to instructions - add egg, water, or oil if the box asks for it


  • 16 oz powdered sugar
  • 2 sticks butter , room temp
  • 1 tsp vanilla extract
  • pinch salt


  • Preheat oven to 350F. Mix the cake batter as the box prescribes, and divide among three 6" cake pans, buttered+floured or prepared with Wilton cake nonstick spray. Bake for 26 minutes (a minute or two less than the box says). Let cool almost completely in their pans.
  • When cool, level off the top. Wrap each layer in plastic wrap and freeze overnight.
  • The next day, when ready to frost/decorate, prepare frosting. In a stand mixer or with a hand mixer, whip 2 sticks of very soft butter with 16 oz of powdered sugar and salt + vanilla, until fluffy.
  • Frost the cake with just a crumb coat.
  • Decorate with flowers! Enjoy!
