Tips & Tricks

  • If working with kids add the popsicle sticks to the rice krispy treats before decorating, but make sure your bowl is large enough to dip the rice krispy treat.
  • It is strongly recommended to use piping bags to have more control over the design, but ziplock bags will work.
  • Sprinkles can be added at each layer if you would like.
  • Each jar should have 3 sections of cake and 3 sections of frosting.
