Looking for an eye-catching 4th of July dessert for kids? Make red, white, and blue finger Jell-O bars.

Jell-O's bright colors make this treat pop out on any dessert table, and it's familiar flavor is sure to be a hit with children.

This Jello recipe is easy to make, but a bit time consuming because you must wait for each layer to set before adding the next. (To save time, make three layers instead of the seven layers you'll find instructions for here.) The effort is worth it, though, when you see the reaction to this patriotic treat.

Tools You'll Need: You will need a 9-inch by 13-inch glass baking dish, a small mixing bowl, a measuring cup with a pouring spout, and a whisk, in addition to the ingredients.

Ingredients

  • 7 cups water (boiling, divided)
  • 2 (3-ounce) packages Jell-O (cherry-flavored)
  • 2 (3-ounce) packages Jell-O (blueberry-flavored)
  • 7 packets gelatin (unflavored)
  • 2 cans sweetened condensed milk (divided)

Steps to Make It

Tips

  • Make sure you wait until the Jell-O cools a bit in the fridge before you pour it over the other layers, as you don't want to pour hot liquid on top of another layer of Jell-O at any time during the process. Doing so will turn the white layer pink or light blue.
  • Each layer is made up of about 1 1/2 cups of liquid.
