If you’ve ever thought it would be fun to make a Lego themed cake or chocolates, look no further. Today I’m going to show you how to make a Lego candy mold that can be used for all those types of things, and more!

Supply List:

• Lego building blocks of any color and all sizes
• Lego base plate
• EasyMold Silicone Rubber
• Large disposable containers (at least two)
• Stir sticks
• Vinyl gloves

Build the frame:

First, we’re going to build a frame of Legos around where we’ll pour the rubber to mold the shapes. Use 2×4 blocks to build a square on the Lego base plate. You will need two layers of Legos to essentially create an outer wall.

You will want to stagger the second layer over the first so that the seams won’t be the same. This method makes the wall stronger and will ensure it won’t break when you pour the silicone rubber into it.

Now place the blocks that you want to make molds of within the outer square. Personally, I wanted the basic sizes, so I placed them evenly spaced within the square frame.

Now that they are all in place, press them down firmly to make sure they are all secure.

Mixing the Silicone Rubber:

Use a 1 lb. package of the EasyMold Silicone Rubber to make your mold. The instructions in the package will tell you how to figure out the amount of each part of silicone rubber you need.

Safety first: put on your vinyl gloves. Now grab part A from your box of EasyMold Silicone Rubber.

Pour part A into your disposable container. I used an old cottage cheese container that had been thoroughly cleaned and dried.

Now grab part B (blue) from your box.

Pour an equal amount of part B into the same container.

Thoroughly mix the two parts together until they are one solid blue color that has no streaks. Make sure that you scrape the sides and bottom and mix thoroughly.

To ensure it is completely mixed, use the two cup method and pour your mixture into a second container (I actually used two more because I didn’t have another large enough.) Again, mix this thoroughly.

Now it’s ready to pour!

Making the Mold:

Start by pouring the silicone rubber into the center of the mold and keep pouring in that same spot. This will ensure that most of the air bubbles will get pushed out as it spreads across your form.

Pour all of it completely into your mold form. Be careful that it doesn’t go over the side walls though! I didn’t have enough to need to worry about that. I just made sure to have enough to cover the Lego pieces I wanted to recreate.

Once it is all poured, press down on the outer wall Lego pieces to make sure the outer wall is solid and secure!

Let the silicone rubber cure for 24 hours.

Removing from the form:

The fastest and easiest way to remove the mold from the form is to flip the entire thing over and slowly remove the base plate.

Now you will want to remove the outer walls which are likely still stuck to the sides of your mold. You can see that a small amount of silicone rubber got between the blocks but this is not a problem, simply pull them off.

Remove all of the inner pieces from the mold. The Silicone Rubber stretches a little so this is an easy task. Just take care not to tear your mold.

Finished!

There you have it; a completed Lego Candy Mold. I even made some hard candies to show you how great it works! You can use this mold for other things like chocolate, ice cubes, jelly candies, etc. It could also be used for resin pieces, just be sure that if you use it to cast non-food items that you mark it because it cannot be used again for food.
