Broken Glass Jello Recipe

Have you ever had broken glass Jello? It’s a Kraft recipe that has been around for ages. It’s one of the most versatile and kid-friendly recipes around…and is perfect for just about any holiday. At Halloween use grape, orange and lime Jello. At Christmas, use lime and cherry (similar to our Christmas jello). In the summertime, make it red, white and blue!

How do you make gelatin cubes?

Making gelatin cubes might seem like an extra step, but it is really easy. The most important thing to remember is to use half of the water that it calls for on the back of the box. We used 2 large boxes of Jello, but you can use 4 small boxes if you’d like. Just remember…use half the water so you can easily cut them into cubes.

Pour the Jello into a shallow baking dish. We like to use a dish that will give us Jello about 1/2″ to 1″ thick. You can do thicker if you’d like, but it will take longer for the Jello to set up and be harder to cut into cubes.

The Jello should only take about 2 hours to firm up if you chill it in a shallow dish.

Once the Jello is firm, just use a sharp knife to cut it cleanly into cubes.

How do you make a broken glass Jello dessert?

Once you have the gelatin cubes made, the rest is easy!

  • Place the jello cubes in whatever pattern you’d like in a 9×13 glass dish. Spray the baking dish with cooking spray so you can remove the Jello easily.
  • Mix the unflavored gelatin into a cup of hot water. Stir until it is dissolved, then mix in the milk.
  • Pour the milky mixture over the gelatin cubes. *Note…make sure the milk mixture isn’t too hot or it may melt the Jello.*
  • Cover it, refrigerate until firm, then serve!

Sugar Free Jello Dessert?

Unfortunately they don’t sell sugar free condensed milk, but they do make a low-fat or lite version that you could try. So although we definitely can’t say this is sugar free, you can lower the calories by using sugar free Jello. Prepare it the same way!

This looks great! Have you ever subbed a dairy free version of milk? We have a dairy allergy in the house and wondering if I could make it with maybe coconut milk.
