Lego Birthday Cake Ideas
What could be more classic than the Lego bricks themselves? This brick cake looks just like the blocks and will be a huge hit at your Lego birthday party. Make the frosting any color you’d like, or create a couple of smaller cakes to make bricks in different colors. This cake is made with boxed cake mixes, which saves time preparing for the big day. | In Katrina’s Kitchen
Capture the look of Lego mini-figures in this fun Lego head cake. The fun thing about it is that you can give the head any expression you’d like! It’s easier than it looks to put together; it just requires some patience and time. She recommends using pre-colored fondant to get the bright yellow look. | Ashlee Marie
Really wow your party guests with this incredible Lego block cake that’s covered in colorful bricks and has a fun block design inside the cake as well. This is another cake that uses boxed cake mix to simplify things, which is terrific. Making the blocked colors inside is simple with a checkerboard cake pan set. | Pink When
Finally, if you’re more of a cupcake person, it couldn’t get simpler than these fun and easy Lego cupcakes with a candy melt brick on top or a LEGO minifigure. You can make them any color you’d like and put a bunch of cupcakes together in less than an hour. It’s the perfect idea for last-minute party planners. | Love from the Oven
Lego Party Food Ideas
Make some Lego cheese and crackers for a quick snack. They’re inexpensive to make, and kids will love them. All you need are crackers, cheese, and a small fondant cutter or knife to cut the circles. Easy peasy! | Tonya Staab
Want a healthy snack at your party? Look no further than these Lego frozen yogurt bricks made with fresh strawberries, blueberries, yogurt, and honey. Parents will be thankful to have one less sugary item available! | Surviving a Teacher’s Salary
Turn ordinary marshmallows into fun yellow Lego head marshmallow pops! Grab regular marshmallows, mini marshmallows, yellow candy melts, and lollipop sticks to get started on this simple tutorial for LEGO cake pops. They make great snacks for the party, adorable LEGO cake toppers or favors for after. | Savoring the Good
Serve up some yummy Lego brownies at the dessert table. Use brownie mix or grab a box or two of the Little Debbie brownies to put them together faster. | In the Kids Kitchen
Lego sandwiches are a breeze to make, too. Peanut butter and jelly sandwiches are popular with kids, but you can do the same thing with deli meat and cheese or even veggie sandwiches if you prefer. Just add the bread circles on top to make them look like bricks. They’d be a great addition to kids’ lunchboxes during the school year, too. | In the Playroom
You can never go wrong with Rice Krispie treats. These Lego Rice Krispie treats are so colorful and fun. Just top your usual recipe with the colorful icing and matching M&Ms to make the bricks. Gel food coloring yields the brightest colors, so make sure you grab gel instead of liquid food coloring. | The Soccer Mom Blog
These Lego cookies look scrumptious, and they’re made from scratch, so you know they’re extra yummy. However, you can probably recreate the idea with pre-made cookie dough and royal icing. | For Modern Kids
Who says you shouldn’t play with your food? These Lego build and play Jello snacks were meant for fun! Make them in all kinds of fruity flavors, and the kids can stick them high while enjoying a jiggly snack. | Passion for Savings
Lego Party Décor
For easy party décor, recycle your corn starch canisters to make some cute Lego heads with different faces. Since they’re already the perfect shade of yellow, there’s no painting involved. Just draw on the different facial expressions, and you’re good to go. Better yet, your kids can use these jars to store their Legos even after the party is over. | Organized 31
Build some of your décor out of Legos! It’s such a clever idea. You don’t have to think big… small items like building your own utensil and napkin holder can pack a big visual impact. To keep it permanently secure, add some hot glue and use forever to hold utensils, napkins or even future LEGO supplies and tableware. | Artsy-Fartsy Mama
Make giant Lego “bricks” with boxes, wrapping paper, and construction paper. You can also create Lego faces by drawing faces on yellow balloons. Both of these ideas are super easy and inexpensive, perhaps check out the Dollar Tree for your decorations! | Desert Chica
Head to the Dollar Store for construction paper supplies. Create a Lego bricks garland using construction paper, tape, a hole punch, and some string. How easy is that DIY LEGO banner? It’s a great way to create colorful party décor without a lot of effort. | A Crafty Spoonful
Lego Party Favors
Our Lego travel case makes an excellent party favor, and they’re not very expensive to put together. Just use discount pencil boxes and Lego tape along with some bricks inside, and you’ve got a fun activity that kids can take on the go and enjoy long after the party is over. | Frugal Coupon Living
Upcycle all your old broken crayons to make some fun Lego man crayons! Talk about inexpensive favors! Aside from purchasing the mold, the little LEGO crayons would be free! Everyone has their own minifigure to go. You can also use the mold to make chocolate Lego figures, too. | Mama Smiles
Use some bricks and colorful yarn to make Lego friendship bracelets for all the party guests. The kids can help make them, but they’ll need an adult to drill the holes in the bricks to run the yarn through. | Kids Activities

Every party needs some photo props and a backdrop to make pictures a little more fun! Making LEGO head photo props is super easy following this tutorial. | Moms and Crafters
For another LEGO party activity, kids will get a kick out of playing Pin the Head on the Lego Dude. It’s a free printable that you can grab for the party and set up in no time. You can use just paper and tape, but if you want the kids to be able to play this over and over, add Velcro tape to the backs of the Lego heads, and place the body on a large piece of felt. That way, it’ll be easy for kids to stick the head on while they’re blindfolded. | Paper Trail Design
Play a game of Lego ball toss to keep the kids entertained! Just cut two or three holes in the top of a painted box for the kids to toss tennis balls into. It’s easy enough for all ages to play, as you can adjust for age by putting the younger kids closer and the older kids further back. Check out the other party ideas here, too.

This Lego bean bag toss is another fun game the kids can play. This game board is made from a box, and you can make simple bean bags using felt. You don’t need to be a pro at stitching to sew simple bean bags, but you could even use fabric glue if you prefer. | East Coast Mommy
It just wouldn’t be a Lego party without a building challenge, would it? Grab this printable challenge and build a spinner out of Lego pieces to make it extra fun. Give it a spin, set a timer, and see who can build the challenge item the fastest (or the best). | Artsy-Fartsy Mama
