Stained Glass Bars

I found this recipe on Kraft's website.  It's really delicious and it just looks pretty!

5 1/2 cups boiling water, divided

1 pkg (3 oz) Strawberry flavored Jell-o

1 pkg (3 oz) Lime flavored Jell-o

1 pkg (3 oz) Orange flavored Jell-o

1 pkg (3 oz) Lemon flavored Jell-o

2 envelopes Knox unflavored gelatin

1/2 cup cold water

1 (14 oz) can sweetened condensed milk

Add 1 cup of boiling water to each flavor of Jell-o in separate bowls.  Stir for 2 minutes until completely dissolved.  Pour each flavor of gelatin into separate small shallow baking dishes sprayed with cooking spray.  Refrigerate for 2 hours or until firm.  

Sprinkle unflavored gelatin over cold water, let stand 1 minute.  Stir in remaining boiling water.  Add condensed milk, mix well.  Cool slightly.

Cut flavored gelatin into cubes.  Randomly place cubes in 13 x 9" pan sprayed with cooking spray.  Pour milk mixture over cubes; stir to evenly distribute gelatin cubes.  Refrigerate 2 hours or until firm before cutting into bars.
