LEGO Superhero Birthday Party

A LEGO superhero birthday party is a fun combination for superhero fans and brick builders!

I have included a list of supplies at the end of the post.

LEGO Superhero Birthday Party
Over the weekend we celebrated my youngest son’s 4th birthday party!

I can’t believe he has already gotten so big. I am in complete denial!

This little guy is head over heels for all things LEGOS. He selected a LEGO Superhero birthday party as his theme.

Seeing as we’ve had both LEGO and superhero parties in the past, I thought this was totally doable.

So buckle in, I have a LOT of photos to share with you!

I will share a list of resources at the end of the post.

Let’s begin with some of the decorations.

While the characters were based on the LEGO Superheroes, the rest of the decor was pretty much comic book superheroes such as city skylines, “POW” symbols, and such.

It was a fun mixture!

I designed SVG files for my Silhouette to cut out the LEGO Superheroes.

I was so pleased with how they turned out!

While we used 9 superheroes on the LEGO Superhero invitation, we narrowed it down to the top 5 favorites to decorate with.

I created a simple city skyline backdrop to match the skyline banner that I purchased 2 years ago when my oldest turned 4 and had a superhero-themed birthday party.

The backdrop on the mantel could not have been easier to make!

The large city skyline in the back is simply from a roll of chalkboard paper.

I cut out a city scene with scissors and used chalk to quickly draw on a few windows.

I attached it to the wall with Frog Tape.

The smaller city skyline in the front is leftover decor from our previous superhero party.

My oldest uses it as a prop when he plays.

It is simply cardboard and black scrapbook paper.

Lego superhero minifigure head banner
Before making the Silhouette templates for the LEGO Superheroes, I had made regular templates and printed them out to make superheroes out of large sheets of foam.

I used the full-bodied foam superheroes to decorate the food table which you will see shortly.

I also made an extra set of just the superhero heads from the foam to make a fun banner.

printable superhero alphabet letters
I used a fabulous superhero alphabet set (see link at the end of the post) to spell out our little superhero’s name.

We’ll be hanging in his room now that the party is over.

LEGO Superhero Birthday Party Activities

The LEGO website has a plethora of fun things that are perfect for parties.

I downloaded several of the coloring pages and had them printed as an easy activity to entertain our little party goers until it was time to eat.

They just loved them!

Speaking of eating, I just love how the food table turned out!

The LEGO Superheroes decorated the front of the table.

We stuck with a red, blue, and yellow theme.

lego superhero birthday cake
I love simplicity of the cake paired with the superhero backdrop!

I always like to put our birthday cakes from and center.

superhero sky jello
We served Superhero Sky Jell-O and Super “Hero” sandwiches as well as “Hulk” green grapes and Super Punch.

The Superhero Sky Jell-O was simply a layer of blue Jell-O, a layer of Cool Whip, and another layer of blue Jell-O.

Jell-O is always a fun treat for little party guests!

Captain America fruit shield
I also recreated Captain America’s shield in fruit and marshmallow form.

You simply need a round serving dish, quartered strawberries, blueberries, and mini marshmallows.

This is such a simple but fun party food idea!

LEGO superhero skyline birthday cake
For the cake topper, I borrowed LEGO superhero minifigures from my kids.

They stand nicely on the cake, and wash off easily afterwards.

How about that cake??

It was 6 layers of red, yellow, and blue pound cake with buttercream frosting.

The city skyline was made with sugar sheet fondant that I cut in half (it is 8″x11″) and cut out the skyline with a clean X-acto knife.

It sticks to the buttercream simply by wetting the buttercream slightly and pressing the fondant on.

The little balls at the base of the cake are mini jawbreakers (but not hard like their bigger brothers so no crunching teeth at the party).

You can read about my marshmallow fondant fail here.

LEGO Superhero Birthday Party Backdrop

I’m really excited about the backdrop for the food table.

It’s all scrapbook paper!

I pieced the sheets together with packing tape on the back.

I can simply cut the tape and still use the paper later.

The number 4 in the center is front the same superhero alphabet used to spell out my son’s name earlier.

LEGO Superhero Birthday Party Favor Bags

I put together some simple goody bags for our little party goers.

I decorated the front with more LEGO Superhero heads made with the Silhouette.

lego superhero slime gak
Superhero Gak was one of the things we included in the goody bags.

My boys made it so that made it even more fun for them to pass out to their friends!

It’s just a combination of Elmer’s glue, borax, and water.

diy lego crayons
Another thing we included in the goody bags was homemade LEGO crayons.

These were unbelievably easy to make!

The LEGO minifigure molds held 1 broken up crayon in each mold and melted down in 15 minutes at 265 degrees F.

The LEGO brick molds were a little larger and took 2-3 crayons to fill which is why they are multi-colored.

They melted down in 20-25 minutes at 265 degrees F.

Also included in the goody bags were superhero masks, Pop Rocks, superhero bracelets, and homemade mini comic books using the comic downloads on the LEGO website.


The LEGO superhero birthday party was SO fun! And my little guy loved it which makes all the hard work TOTALLY worthwhile.

Hi Megan! The SVG files for the superheroes are not for sale. I only sell the finished product on cardstock. Thanks!

Wow! This party idea is amazing. Thanks so much for the share!

I was hoping you could point me in the right direction on how to get the lego heads & the full lego printables (I think you said you put them on foam). I'd love to get these as well if possible. Thanks

Hi Veronica! I recently added the heads and bodies in my Etsy shop. They are made of cardstock since that is much quicker and easier for me to make than hand cutting the foam. You can find them here:
