An easy way to upgrade boxed cake mix into an elegant naked cake with flowers and the perfect amount of frosting!



  • 1 box of white or vanilla boxed cake mix, mixed to instructions


  • 16 oz powdered sugar (see here how to make powdered sugar at home)
  • 2 sticks of butter – very soft
  • 1 tsp of vanilla extract
  • pinch of salt


  1. 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.
  2. When cool, level off the top. Wrap each layer in plastic wrap and freeze overnight.
  3. 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.
  4. Frost the cake with just a crumb coat.
  5. Decorate with flowers! Enjoy!
