Lego Crayons- A Birthday Party Favor (plus free printable and other resources)

Sharing is caring!

Take a box of 72 crayons, which likely costs less than $3.00 to purchase, and make it into 36 Lego shaped crayons that you can use to fill your goody bags for your Lego themed party!

Lego Molds

I’ve shared before how to make your own crayons using your favorite mold and broken crayon pieces. It is a great way to recycle, but they also make excellent gifts. It is something your children can help you do and it is so much fun to see what amazing color combinations and masterpieces you can come up with.

Each individual Lego mold holds two whole crayons when broken into pieces.   You can find the LEGO molds on Amazon.

Want to make your own Lego mold? You can! Topsy Turvey has a step by step tutorial and you can use these molds to make candy, soap, crayons, you name it!

Lego Crayon Creations

From left to right these are the masterpieces we made. Purple Mountain Majesty/Periwinkle, Melon/Apricot, Dandelion/Yellow, and Sky Blue/Sea Green. The Sky Blue and Sea Green combo reminded me of a globe. Loved it!

These earth-toned crayons turned out great. The older kids at the party really like them.  (from left to right) Plum/Pacific BlueAsparagus/Olive Green, Cadet Blue/Golden Rod, and Tumbleweed/Brown.  

Even though some may think Lego’s are more boyish, you can totally make them in girly colors! I really loved these! Timberwolf/Carnation Pink, Green Yellow/Yellow Green (who knew),  Wisteria/Mauvelous and my favorite of them all is Robin Egg Blue/Tickle Me Pink.

These were fun, too! Crayola names have come so far and it makes creating even more fun! Mac & Cheese/Granny Smith Apple, Burnt Orange/Scarlett, and Black/Orange (perfect for Halloween!).

Lego Crayon Party Favors

To package these Lego crayons up, just place them in a small size cellophane treat bag that you can buy in mass quantity at your local craft store. Use 4×6 pieces of card stock and print them  up with a fun saying. I just Google Lego sayings and came up with:

Build It.

Play On.

Imagine in color….

Then, fold the card stock in half, cut to adjust if needed, and staple to your crayon filled cellophane bags.

You can also download a Lego font here, if you would like.

Partner the crayons with a fun, free, printable Lego sheet, and you have an inexpensive party favor that matches your theme perfectly! 

What color combinations will you make?

I am sharing this fun idea on these crafty and resourceful sites.


  1. What a cute idea! My son just had a birthday and these would have been great. I’ll have to save it for next year or just have a fun playdate!

    1. Glad you like it Marci. Give it a try and have fun with it. 🙂

  2. This is SOOOOOOOOO cool! I love these! I really am considering trying to talk my kiddo into a lego party next year! Who’d have thought =)

    1. Awesome, SweetSugarBelle! Lego paries are SO MUCH fun! 🙂

  3. What a cool idea! I’ve been wanting to make our own crayons. I like the swirls.

  4. OMG, I love these! I’m totally going to send this link to my sister 🙂
    Oh, saw you on Works For Me Wednesday 🙂

    1. Tiffany- how exciting and cool to share this with your sister! Thanks so much and thanks for the kind words. 🙂

  5. Erin @ Making Memories says:

    How fun! I’m going to bookmark this for my son’s birthday!

  6. What a great idea and Lego party favor!!!

  7. I am trying to look for the cake pans so Ican do this and Ican’t find them. Do you have any ideas where we could find some? They are sooo adorable that I would love to do them for my sons birthday party 🙂

    1. I do not know if they make cake pans or not…. you may search on Ebay or Craigslist for Lego Cake Pans.

      These that I used are silicone molds meant for smaller things like candy, soaps, crayons, etc. Each crayon is about 1 in. x 2 in. They are oven safe, so you could make micro-mini cakes with them. I bought them on ebay.

  8. I’ve seen some great Lego birthday ideas lately but nothing for favors. These are wonderful. I love the fact that they are homemade and sweet free!

    1. Stacey-

      If you’re looking for sweet free, another fun idea would be to make soap using the molds. I’ve seen lots of tutorials on different blogs with step by step directions on how to make soap and you could use the Lego molds for that. These are great in the favor bags as well. Just label them… or you’ll have little ones trying to draw with soap and washing their hands with crayons. 🙂 Here is one tutorial for making soap (and she also shares how to make a Lego mold if you are feeling up to it, I just bought the molds I used for our party.)

      And you can also make Lego Playdough for the party favor bags:

      And, if you’re having the party at home, you can make ice for their drinks using the molds as well.

      Oh, and another non-candy favor for Legos that I wanted to do but ran out of time…. take a small Legos and turn them into necklaces. For real! 🙂 Here is the tutorial:

      As you can see, I could go on and on. I love me a birthday party! 🙂

  9. Found you at Keeping it Simple’s Motivate Me Monday.

    My son has been asking for a Lego birthday this summer…I love this idea!!!

    1. Glad you found me! Best of luck on the party this summer! 😉

  10. Thank you for sharing! I have been wanting to make crayon party favors from an old crayon bin my boys have! This will make them like new again.

  11. What a great idea! Thanks for sharing.

    (found you on Skip to my Lou’s monday linky party)

  12. I LOVE these!! I have 2 little boys so this would be something super fun to do with them! 🙂
    Thank you for posting this!

  13. thank you for posting this! I’ve been wanting to find lego molds for crayons and soaps. I’ve been wondering where you get them. this is awesome.


  14. Did you put the Lego mold into the oven on 300 (like you did with the heart crayons)? I am making these in a few days for my son’s birthday, but I’m hesitant to put the Lego mold in the oven.

    1. Yes Kim, I baked it in the oven just like the heart crayons. Just make sure your mold is oven safe- the packaging should indicate if it is or not. 🙂

  15. Oh my goodness! I found your blog by googling “lego crayons.” Now that I’ve looked around your site some more, I found your post about your son Matthew’s birth. The pictures look like you delivered at the Baylor downtown. If that is the case, we live in the same town! I delivered my second by c-section there in January 2011. Crazy what a small world it is!!

  16. I’ve done this with these exact molds. Super easy! The crayons popped out great. How did you clean the crayon residue out of your molds?

    1. Jeana- crayon residue is pretty tough to get out of the molds. I did find a tutorial link at one point with tips for cleaning the crayon residue out. It is linked in one of my how to recycle crayons posts. I will have to find it.

      I do suggest that once you make crayons in a mold, let it be dedicated to non food items only. I have never made candies in a mold once it has had melted crayons in it. I have two lego bricks molds- one for candy and one for crayons, for example.

      1. Yes, I wish I had known or thought of that before hand.
        It’s taking a lot of elbow grease (and achy fingers) but Vasoline is doing wonders right now! 🙂
