Make your own LEGO crayons perfect for a non-candy valentine or LEGO birthday party favor.

LEGO Crayon Valentines

It’s no surprise that my LEGO fanatic 6 year old wanted LEGO Valentines this year.  I ran across some LEGO molds earlier this year and bought them on sale thinking I’d use them for Carter’s birthday. I didn’t get around to doing anything with them at the time, but Valentine’s day seemed like a good time to put them to use. As with many schools these days, we cannot make homemade treats for school due to possible allergy issues for many kids, so making LEGO chocolates were out. My second favorite option was making our own LEGO crayons.

LEGO Crayon Supplies:

  • LEGO Molds – I used both bricks and minifigure molds which I bought in a set.
  • Crayons – I recommend using Crayola. I’ll show you why later. For these you’ll need 1 crayon per minifigure and 2 crayons per brick.
  • Baking Sheet
  • Parchment Paper (optional – to protect your baking sheet)
  • LEGO Figure printable or other card/tag
  • Colored card stock
  • Small plastic treat bags

Heat oven to 250 degrees. Cover your baking sheet with parchment paper.

Peel the paper off of your crayons. HINT: I cut a slit down the side of each with an Xacto knife to make peeling easier.

Break up your crayons and fit them into your molds. You may need to cut them if you can’t get them roughly the right size by breaking them. This doesn’t need to be perfect, they will melt and fill in all the spaces. you can choose to do single or multi-colored. We made some of each. I preferred the single color, but Carter liked the multi-colored ones better.

Put into the oven for 10-15 minutes, until fully melted. Remove from oven and let sit for 15-20 minutes until semi or fully solid. Put into freezer for at least 10 minutes. Push crayons out from the mold. You may find it easier if you run the backside of the molds under hot water for a few seconds.

Lego Crayon - multi-color head and body

I originally tried using random old crayons from restaurant kids meals, but found that they often have two much wax in them and the color and wax separated horribly in those. This happened minimally or not at all with Crayola crayons.

We decided to put the LEGO crayons onto LEGO figure shaped cards. I found a LEGO figure outline and then used my Silhouette Cameo with the print and cut feature to make the cards. If you’re looking for a LEGO font, I liked this Lego Thick font from UrbanFonts.

In order to hide the top of the bags, I made the head as a foldover, folded in the bags at the corners and then stapled together at the neck.


If you have a Silhouette, feel free to contact me via email or through the comments and I can send you the cut file.

You could also just attach a little tag to the bags or print off the LEGO outline and let the kids color them in.

      Thanks! It took my son awhile to actually use them. He didn’t want to wear them down. I assured him that we could make more!
