Knox Blox

With hot summer days making it impossible to use an oven, I love cold refreshing treats that are easy with no baking necessary. My mom has made these a tradition since I was little. Unlike Jello Jigglers, Knox Blox are much firmer and easily transported. No fork or spoon required. Sugar free Jello can be substituted for an even lighter snack.


4 envelopes of Knox unflavored gelatin

3 pkgs (4 oz) flavored Jello gelatin

4 cups boiling water


Mix Jello and Knox gelatin into a bowl.

Add boiling water. Stir until dissolved.

Pour into 9×13 inch pan and refrigerate 4-5 hours or until firm.

Cut into squares or use cookie cutters for fun shapes!

    This brings back memories…….instead of water use fruit juice, it makes them a little healthier.
    Another trick is to add a 7UP type soda to make them fizzy.
    I will never forget the first time I had regular jello at a friends house. I was sure her Mom had messed it up. You see my Mom always made ours special by adding juice and a llittle soda pop, but I thought everyone made their jello that way.
    Nothing better then sticking your tongue through the jello and tasting the “fizz!”

      There are directions on the Knox package which does substitute juice for the water but then doesn’t use any Jello. I haven’t tried the 7 up version but that sounds yummy!
