  • 4 packages 3 ounces each assorted flavored gelatin
  • 1.5 oz unflavored gelatin divided
  • 5-3/4 cups boiling water divided
  • 14 oz sweetened condensed milk
  • 1/4 cup cold water


  • In a small bowl, combine one package flavored gelatin and one envelope unflavored gelatin. Stir in 1 cup boiling water until dissolved. Let mixture cool slightly for 3-5 minutes.
  • Pour mixture into a 13-in. x 9-in. dish coated with cooking spray.
  • Refrigerate until set but not firm, about 20 minutes.
  • In small bowl, combine the condensed milk and 1 cup boiling water.
  • In another bowl, sprinkle two envelopes unflavored gelatin over cold water; let stand for 1 minute. Stir in 3/4 cup boiling water. Add to sweetened condensed milk mixture.
  • Spoon 1 cup of the creamy gelatin mixture over the first flavored gelatin layer. Refrigerate until set but not firm, about 25 minutes.
  • Repeat from beginning of recipe twice alternating flavored gelatin with creamy gelatin layers.
  • Make sure to let the dissolved gelatin sit for a few minutes before spooning over previous layer. This will keep the layers "pure".
  • Chill each layer until set but not firm before spooning next layer on top.
  • Make final flavored gelatin and spoon over top.
  • Refrigerate for 2 hours after finishing last layer before cutting into 1-in. squares.
  • Serve and enjoy!
