Ingredients

  • 12 ounces Jello mix 4 – 3 ounce packages
  • 0.5 ounces unflavored gelatin packets 2 packets of Knox
  • 12 ounces sweetened condensed milk 1 can

Instructions

  • Dissolve each box of Jello in separate bowls using only one cup of boiling water.
  • Place the jello into the refrigerator and allow it to cool until set.
  • Once the flavored jello is set, make the white gelatin.
  • Bring 1 ½ cups of water to a boil.
  • Add 1/2 cup of COLD water to a small bowl and sprinkle the gelatin powder over the water, mixing as you add the gelatin. Let it sit for 1 minute or until it has thickened.
  • When the gelatin has thickened, add the 1 ½ cups of boiling water and stir to combine well.
  • Add the sweetened condensed milk and stir.
  • Allow the milk mixture to cool for about 30 minutes.
  • While the milk mixture is cooling, remove the flavored Jell-O from the refrigerator and cut it into cubes.
  • Place the cubes into your serving container, I like to use my 9 X 13 glass baking dish. Spread the Jello blocks out evenly.
  • Pour the cooled milk mixture over the Jello cubes. Stir gently if needed.
  • Place the dish into the refrigerator and chill until it has set. This could take up to 4 hours.
  • To serve, remove the dish from the refrigerator and slice it into pieces.

Notes

  • If using only one flavor, both packages of flavored jello can be made in the same bowl, just make sure you only use one cup of water per package.
  • If you cool your condensed milk/gelatin mixture and it is too thick to pour, reheat it in a microwave on full power for 30 seconds and stir. You can do this a couple of times if necessary. Allow it to cool for a few minutes before using it so you don’t melt the Jello cubes.
  • Do not stir too much after adding the warm milk mixture to prevent melting the flavored cubes.

Pro Tips

When you cut into this dessert it looks like broken glass. That’s why some of the old-fashioned recipes call it stained glass cake, it looks like chunks of glass floating in a white ocean of flavor. Kids love it.

  • You can use one bowl for the flavored Jello when making only one color. Any brand of flavored gelatin will work, even sugar-free.
  • If you need a Knox gelatin substitute, you can use 6 gelatin sheets or agar-agar. Follow the manufacturer’s directions for substituting 1/2 ounce of powdered gelatin.
  • Make sure you have cooled the milk mixture enough that it won’t melt the flavored cubes. Gently stir after adding it to avoid breaking up the cubes.
  • If the milk mixture cools too much and gets too thick to pour, reheat it in a microwave in 30-second increments.

You can easily make this recipe for any holiday, just change the colors. I use red and green Jello for Christmas time and blue and red for a super easy Fourth of July dessert or all red for Valentine’s Day.
