The trick to making this turn out beautifully is to create thin layers and let them set completely before pouring the next layer. It’s very important to follow the directions exactly and let each mixture cool enough so that it doesn’t end up melting the layer below it when you pour it on.

• 6 small (3 oz) packages different colored Jell-O -OR- 3 large (6-oz) packages, if making 2-3 colors
• 1-oz Knox unflavored gelatin (4 packets coming in 1 pack)
• 1 (14-oz) can Sweetened Condensed Milk
• Glass 9″ x 13″ pan

Jell-O Layers: Mix 1 package of any flavor/color Jell-O with 1 tsp Knox gelatin and 1 cup boiling water. Cool and pour into pan; refrigerate until set. Ensure that your fridge shelf is level so your layer sets evenly and doesn’t turn out thick on one side and thin on the other. It takes about 30 minutes to set up in the fridge before you can move on to the next layer.

While waiting for your Jell-O to set, make the next layer and leave it to cool on the countertop.

White Layers: Mix 1 envelope Knox gelatin (or 2 tsp Knox if using the bulk can) with 1/2 cup hot water until dissolved. Add 1/2 can condensed milk and an additional 1/2 cup hot water. Once cooled pour 3/4 cup (just enough to cover the Jell-O and make a thin layer) of the milk mixture over the set Jell-O and refrigerate until firm. It takes 30 minutes for this layer to set up in the fridge. As soon as you put the white layer in the fridge to chill make the next color jello so that it will have 30 minutes to cool on the counter.

You’ll make this twice so it doesn’t harden during all the cooling time. Also, make thinner white layers or you’ll run out.

Repeat first and second layer directions ending with a color Jell-O layer.

Once you run out of the white mixture, repeat White Layer directions again.

Continue repeating layers until you are done.

Once finished, cover with plastic wrap and refrigerate overnight to set until firm. Then slice into rectangles, squares, or shapes and serve.

This. Takes. Hours.
