Glass Block Jello

I came across this recipe on OurBestBites.com and thought it looked so awesome! I couldn't wait to make it! It was super easy and came together nice! It was pretty to look at and tasted just as good! The kids all loved it, but then again, who DOESN'T love jello?! Very fun and easy to coordinate colors according to a party or holiday. Fun side dish!

**Note** when I made this, I didn't realize my pan was tilting in the fridge so when I pulled it out it was uneven, so make sure your pan is sitting straight in the fridge so all the squares end up even :)

4 3-oz. packages assorted Jello (in coordinating colors)
2 packets unflavored gelatin
1 14-oz. can sweetened condensed milk
Spray 4 small food storage containers (like Tupperware/Gladware/Rubbermaid) with non-stick cooking spray. Set aside.
Bring just over 5 cups of water to a boil. Combine 1 c. boiling water with 1 package of 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, preferable overnight.
When the Jello has set, bring another 1 1/2 c. of water to a boil. While the water is heating, sprinkle 2 packets of unflavored gelatin over 1/2 c. of cold water. Allow to stand for about 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 9×13″ pan with non-stick cooking spray. Carefully cut the colored Jello into cubes and gently toss to combine in the 9×13″ pan. Pour the cooled milk mixture over the colored Jello and, if necessary, rearrange some of the colored Jello 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.
