Step 1

Mix 1st flavor of Jello with 1 teaspoon unflavored gelatin and 1 cup of boiling water. Let cool (not as important with the first layer), and pour into a 9 x 13-inch pan. I like using a Pyrex pan so I can see the layers.

Step 2

Refrigerate for  30 minutes while making the next layer.

Step 3

Mix 1 envelope of unflavored gelatin with 1/2 cup of boiling water and mix until dissolved. Add half a can of sweetened condensed milk* and another 1/2 cup of boiling water. Mix until combined.

Step 4

When the first layer has chilled, pour 3/4 cup of the sweetened condensed mixture over the top. Chill for 30 minutes while you make the next colored layer.

Step 5

When layer two has chilled, pour layer 3, the second colored layer over the top. Chill for 30 minutes.

Step 6

When layer 3 is chilled, pour the rest of the sweetened condensed mixture over the top and chill for 30 minutes while making the next layer. If the sweetened condensed mixture has started to gel, just place the measuring cup in a bowl of warm water and mix until it liquefies. Use as directed.

Step 7

Since the sweetened condensed mixture has been used, you'll need to make another batch from the rest of the can. Mix 1/2 cup boiling water with 1 envelope of unflavored gelatin, then mix in the rest of the sweetened condensed milk, then another 1/2 cup boiling water.

Step 8

Continue until you've used up all 5 boxes of Jello and all the sweetened condensed mixture in the same manner as before.

Step 9

After the last layer is poured, refrigerate overnight, covered with plastic wrap. Cut into squares or fun shaped to serve.
