Key Ingredient Notes & Tips

Fresh Marshmallow QualityUse fresh mini marshmallows rather than an old stale bag; fresh marshmallows melt smoothly and stay soft.
Butter RatioReal butter gives rich flavor and prevents the squares from drying into hard bricks.

Instructions

  1. Melt butter in pot over low heat. Add marshmallows and stir until melted and smooth.
  2. Remove from heat. Stir in vanilla, cereal, and reserved marshmallows until coated.
  3. Gently press into parchment-lined 9x13 pan. Cool for 30 minutes, then slice.
