Prep Time 15 minutes
Setting Time 8 hours
Servings24 2x2 squares

Equipment

Ingredients

  • 4-5 3-ounce packages assorted Jell-O in coordinating colors
  • 2 packets unflavored gelatin (¼ ounce, or 2¼-2½ teaspoons)
  • 1 14-ounce can sweetened condensed milk
  • non-stick cooking spray neutral flavored variety

Instructions

  • Spray 4 small food storage containers (like Tupperware/Gladware/Rubbermaid) with non-stick cooking spray. Set aside.
  • Bring 5+ cups of water to a boil. Combine 1 cup boiling water with 1 package of Jell-O, stirring until dissolved. Place the dissolved Jell-O in one of the prepared containers. Repeat with the remaining packages of Jell-O. Refrigerate for at least 4 hours, preferable overnight.
  • When the Jell-O has set, bring another 1 ½ cups of water to a boil. While the water is heating, sprinkle 2 packets of unflavored gelatin over ½ cup of cold water. Allow to stand for about 4 minutes. When the water is boiling, pour 1 ½ cups boiling water over the dissolved gelatin and stir to combine. Add the sweetened condensed milk and mix well. Allow to come to room temperature.
  • Lightly spray a 9×13″ pan with non-stick cooking spray. Carefully cut the colored Jell-O into cubes (right in the containers) and gently dump/scrape into the 9×13″ pan. Toss gently to distribute the colors and spread into an even layer.
  • Pour the cooled milk mixture over the colored Jell-O and, if necessary, rearrange some of the colored Jell-O to make sure it is evenly distributed and not sticking out of the white mixture too far.
  • Place the 9×13″ pan in the refrigerator and chill overnight. Cut into squares, rectangles, or various shapes with cookie cutters and serve.

Notes

  • Store finished Jell-O, tightly covered, cut or uncut, in the refrigerator and enjoy within 3-5 days for best results.
  • Don't worry if your blocks aren't all the same size, or if they don't come out of your containers 100% cleanly. Use a silicone scraper to gently pop them out of the food storage containers if necessary. Once they're all mixed up, you won't notice the little pieces!
