Glass Block Holiday Jello

4-3oz packages assorted jello
2 packets unflavored gelatin
14oz can sweetened condensed milk

Spray 4 small tupperwares with cooking spray and set aside.

Bring 5+ C water to a boil. Combine 1 C boiling water with 1 package jello stirring until dissolved. Place the dissolved jello in one of the prepared containers. Repeat with the remaining packages of jello. Refrigerate for at least 4 hours, preferably overnight.

When the jello has set, bring another 1 1/2 C water to a boil. While the water is heating, sprinkle 2 packets of unflavored gelatin over 1/2 C cold water. Allow to stand for 4 minutes. When the water is boiling, pour 1 1/2 C 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 9x13 pan with non-stick cooking spray. Carefully cut the colored jello into cubes and gently toss to mix in the 9x13 pan. Pour the cooled milk mixture over the colored jello mixture and rearrange some of the colored jello if necessary. Place the 9x13 in the refrigerator and cool overnight. Cut into squares or rectangles or various shapes with cookie cutters.
