DIY Lego Jello Tutorial

|by | Lego, Ninjago

I made this Lego Jello for a Ninjago themed birthday party. Jello is one of my favorite treats to have at a child’s party; It’s easy, inexpensive, always a hit with the kids and you can do so many things with it!


The usual Knox Blocks recipe didn’t work for these Lego molds, it was just a little too soft, causing the tiny parts on top to break off in the mold. I found a recipe online using Jello to make homemade fruit snacks. It used the basic recipe with only 1/3 cup water. This recipe worked and held well, but you would need A LOT of Jello to make enough for a party.


So I experimented with different amounts of Jello and water until I came up with the perfect ratio and a super cute treat!


You’ll need:

Lego mold – I used two of each of these molds and had a little extra Jello left over that I just poured in a bowl to set. You could halve the recipe using a 3oz. box of Jello and half the other ingredients.

6oz. box of any flavor Jello

4 envelopes unflavored gelatin

2 cups water




Pour one cup water in a bowl. Sprinkle unflavored gelatin over water and let sit while you do the next step.

Heat one cup of water to boiling and dissolve flavored Jello in boiling water.

Pour boiling Jello mixture into bowl with the water/gelatin mixture. Stir until all gelatin is dissolved.

Let cool slightly.

Place molds on a flat cookie sheet.

Pour Jello mixture into your molds. I used a liquid measuring cup to make pouring easier.

Put in refrigerator to set for about 2 hours.


I apologize for the lack of pictures, I’m sure I’ll be making these again and will take some to update the post. Being the most popular treat the Lego men were gone before I even got a picture! Think REALLY cool gummy bears.
