Published on: March 13, 2014

LEGOs are not only time-tested, educational building toys — they are also addictive (but in a good way!) fun — for both kids and adults. Since these iconic bricks come in all shapes, sizes and colors, a LEGO party theme works for almost any age and either gender. Check out these great ideas for planning and pulling off the perfectly constructed party for your LEGO fiend — from invite to the goodbye goody bag.

LEGO party invitation

You’re invited!

Kara over at Simplistically Sassy created these cute LEGO invites by cutting blue construction paper into quarters, and then printing the party info onto each. Six cutout circles in a corresponding color, adhered with pop-ups to the blank side of each quarter, give these brick invites a 3-D appearance. Print the word LEGO, along with each invitee name, to customize (a link to download the LEGO font is included in the post).


LEGO party door hanger

Welcome to the party

This bright LEGO door hanger, demonstrated by Planted by Streams blog, is the perfect way to welcome guests to your party. Simply take a LEGO building plate (available online or in stores) and deck it out with blocks forming the number representing the age your child is turning on the big day. Rig up a ribbon and two binder clips to hang, and when the guests leave, move it from your front door to the the birthday boy or girl’s bedroom door!

lego party banner

A banner celebration

Anisa of Lacie Bird blog fame created this fabulous LEGO party banner using foam sheets purchased at a craft store as the base for each section. Six circles cut from the same color foam and then adhered to both sides of each sheet made this banner look great from both the front and back. Holes punched along the top edges of each giant LEGO block make stringing the banner a breeze. Once the party wraps, this festive festoon enjoys a second act as cheery decor in a playroom or bedroom.


no bake lego cake

No-bake LEGO block cake

Check out this clever and easy-to-assemble LEGO cake from the devilishly creative Cranberry Teatime blog. Why bake your own cake when you can create these beauties out of store-bought ingredients in a snap? Rachel used three Sara Lee pound cakes, cutting off the tops to make the surfaces flat, and large marshmallows for the connectors. She covered each cake with tinted frosting, each in a different color, and then stacked them together like LEGO building blocks. Genius!

lego cake pops

LEGO cake pops

Amy of the Living Locurto blog takes the cake with these adorable LEGO mini figure cake pops. Made like standard cake pops by mixing together a crumbled, baked cake with a can of frosting, these twee tasties are topped off with an M&M. After inserting a lollipop stick and setting the cake pops in the freezer, Amy finished them off with a plunge in yellow candy melts and an application of features with a food decorating pen. Check out the full post for full instructions and tips.

lego party food snack crackers

LEGO snack crackers

Want something savory to offset all those party sweets? Layer cream cheese and a slice of cheddar in between two rectangular-shaped crackers (Club® brand crackers work well), top with cheddar cheese circles — and, voilà! — you have a super-cute little LEGO cracker sammie, like these from Simmworks Family blog. Yum!

Lego juice box covers party food

Lego juice box covers

These wrappers are so easy to make, but impressive nonetheless! Cut cardstock in a variety of colors into strips long enough to wrap around standard juice boxes. Secure with clear tape and then add two circle cutouts from the same color paper to the front of each. Glue dots work well for adhering the circles. Just be sure to remove the straws first! Check out the Over the Big Moon blog for more LEGO party inspirations.

Pin the Head on the LEGO Man

Gina of the East Coast Mommy blog created this fun Pin the Head on the LEGO Man party game. Assembled with a white Bristol board as a base and colored construction paper body part cutouts backed with double-stick tape for safe “pinning,” this game will be a delighter and distractor for young LEGO enthusiasts. Head on over to her blog to snag the free printables!

lego bingo game

LEGO Bingo!

We love this LEGO Bingo game dreamed up by Jennifer on the blog Big D and Me. Featuring LEGO images instead of letters and numbers, this game is perfect for even very young party guests. Visit the post to grab free game card printables and see other LEGO-rrific ideas.

lego party game collaboration build together

LEGO collaborative building game

This game idea comes from the the nominal creatrix of Delia Creates. Delia wrapped up groups of random LEGO blocks in gift wrap, and then put the packages into a big bowl. Party guests then sat around a LEGO building plate and passed the bowl, taking turns opening a wrapped package and using the blocks to start or add to the collaborative build site. What a neat idea!

timed tower building lego party game

Timed tower building

Over the Big Moon blog comes through with another fun party idea. Instruct the kids to sit in a circle on the floor or around a table and give each of them the same number of LEGOs. Set a timer for one minute. When the game begins, each guest will build a tower with their blocks, stopping when the timer buzzes. The highest tower wins! Repeat the game with longer or shorter time intervals and award a prize to each round’s winner.

Party Favor lego frame

Party favor frame-up

These cool LEGO frames were created by Melanie at the Ewe Hoooo! blog. It is amazing what a creative cat can do with a glue gun and inexpensive supplies from the craft store! Hand them out empty for guests to grace with a selfie, or print out LEGO pics to frame for a fun and unique party favor!

lego soap party favors

Leggo my LEGO soap

These LEGO party favor soaps are the genius creation of Farmish Mama — practical and cute! And also apparently pretty easy to make, requiring simple ingredients — a LEGO soap mold, glycerin and coloring — and process: Just melt the glycerin in the microwave, add coloring and then pour into the mold to set. Bathtime just got a little more fun.

lego jars party favors

Upcycled LEGO storage jars

We *heart* these little LEGO storage jars made from recycled baby food jars! Victoria over at the ObSUESSed blog made them from recycled baby food jars coated with yellow paint; each jar is then finished with black Sharpie details and a top sealing coat of clear spray paint. Fill the jars with LEGO block candy or real LEGOs for a party favor any brick-obsessed party-goer will love.

lego gift bags

LEGO gift bags

Need a bag for your guests to carry home all that great loot? Crafty Girl of the Crafty Corner blog offers this terrific gift bag idea. And can we say how easy and budget-friendly these look to pull off? A self-described crafty bargainista, she purchased colored bags and simply cut out and applied 1.5-inch-diameter circles to the fronts.
