4th of July Jello Recipe

Every 4th of July, we head to our city’s parade and sit in the same spot our parents stake out every year.  After the parade we walk through the park and taste all the delicious food being cooked up and browse through all the vendors peddling their wares.  I seriously love it!  We usually head home during the heat of the day for a barbecue before returning for fireworks in the evening.  I knew my family would love this festive treat to help them cool down on a hot day!

  • 1 (6 ounce) box red Jello
  • 1 (6 ounce) box blue Jello
  • 1 (14 ounce) can sweetened condensed milk
  • 2 (1 ounce) envelopes Knox unflavored gelatin
  • Water


  1. For each flavor, dissolve one box of Jello in 2 cups of boiling water. Pour into two separate 9x13" pans and chill for at least 3 hours, or overnight.
  2. After chilling the flavors, cut them into small squares. Mix both colors of Jello squares in one 9x13" pan. In a separate bowl, sprinkle 2 envelopes of unflavored gelatin into 1/2 cup cold water. Let the gelatin expand in the water for a few minutes, then add 1 1/2 cups boiling water and whisk together until the unflavored gelatin dissolves.
  3. Mix in the can of sweetened condensed milk, stir and let cool at room temperature. Once the milk mixture has cooled, pour over Jello squares in the 9x13" pan. Chill for a few hours until set up. Cut into blocks or shapes and serve.

    Yours looks amazing! I think I let the sweetened condensed milk gelatin mixture cool too long, an hour. It started to set and was more like a pudding than a liquid. I tried layering/scattering my Jello cubes to mix color and poured the sweetened condensed milk mixture, but my last 1/4 of Jello cubes didn’t sink. I didn’t get the smooth top but a jagged surface. Could I achieve the smooth top by flipping it out of the 9x13 and allowing the smooth bottom to be the top? Should I have sprayed the 9x13 with a nonstick spray first? It’s in the fridge for the final set. I’m afraid if I try to flip it then it might fall apart. It looks colorful and I’m sure it’ll win points with the kids, but I don’t have tons of Jello experience besides just pouring it into cups.

      This recipe calls for 2 (1 ounce) packages of Knox gelatin. I could only find 1-ounce boxes that had 4 (0.25 ounce) packets in each one. I bought two boxes because that is equivalent to 2 ounces. As I was opening each of the 8 (0.25 ounce) packets into the cold water I had a feeling it was too much but decided to follow the recipe. Needless to say, it set up so hard it was like rubber!! Such a pretty dessert but should I have only used two of the 0.25 ounce packets? Or any other suggestions on why it would have set up so hard?

        I also bought 2 boxes of Knox gelatin containing 8-0.25 oz. packets for a total of 2 oz. and was wondering the same thing. It seemed like a lot. Thankfully I checked the site again to see if there were any comments about this before I made it. I followed your advice and used two 0.25 oz. packets (for a total of 0.5 oz.) and it came out perfectly. Teri, thank you for your comment!
