Notes

Nutrition facts are only an estimate 
  • One container of frosting will cover the cake, but two are recommended for layering and decorating.
  • Trim cake tops if you prefer a flat surface.
  • Use plenty of frosting to help candy pieces stick.
  • This cake is meant to be fun and rustic—no need for perfection!
