Lego Cake Ideas

Thank you for Sharing!

If you’ve ever looked online for Lego Cake ideas, you know there are some really great ideas out there! For my son’s 7th birthday, I wanted to make him a fabulous Lego themed birthday cake. Whenever I am getting ready to make a birthday cake, I usually have already been searching Pinterest for ideas. I save my favorite finds, and then make a plan in my head of how I am going to use those ideas to create a one-of-a-kind cake.

This time, it was no different. I found a lot of great Lego ideas on Pinterest, not just for Lego cake ideas, but for a Lego themed birthday party, too! Let me share with you some of the ideas that I’ve used over the years.

Lego Cake with Fondant Bricks

This Lego cake with Fondant Bricks uses buttercream frosting for the cake part, and marshmallow fondant for the brick part. I wanted the cake to taste good, too– not just look pretty!

Lego Cake with Lego Scene

Next up is a Lego Cake with a Lego Scene on the side.

When I was making this cake, I tried to make a cake that looked like giant Lego bricks were stacked on top of each other. But….. I tried using pourable frosting but it was too thick…. so it ended up looking more like a volcano!

So to make up for that, I built a cool Lego scene on the side of the cake, with the minifigs holding the candles, and one of them dangling from a crane!

Ninjago Lego Cake

This Ninjago Lego Cake is actually a cupcake cake. It was a challenge to make a cake that looked exactly like this blue minifigure (Jay) that I was thrilled to succeed at doing! I think it is my best Lego cake yet! (and easier to make than one with Lego bricks.)

Choose which cake to make based on your Skill Level

There are a lot of options to choose from when you are looking for Lego cake ideas. Choose a combination of ideas that match your skill level in cake making. For example, I didn’t think I could make an entire cake out of fondant Legos and have it look nice. That is why I made most of the cake like a regular cake with frosting, and then added the fondant Lego border. Although, after making these fondant Legos, my confidence has grown and maybe I would be brave enough to try an entire fondant cake next time.

I would recommend the same method for you, too. Choose the kind of cake that matches your skill level so that you will not be overwhelmed when making it (or worse– have a “Pinterest Fail” kind of cake!).

Let me tell you from experience– it is very hard to make a homemade cake with a Lego theme that looks professional. Be prepared that, even though you have made plenty of pretty cakes in the past (like I have), that making a DIY Lego cake is just hard.

Why is Making a Lego Cake hard?

Well, I think making a professional looking lego cake is hard because those bricks are perfect. They are perfect rectangles or squares, and that is very hard to reproduce whether you are using frosting or fondant.
If you want your Lego cake to look, well, like Legos– then this might be that one time that you want to splurge and hire a professional cake baker. Just be prepared to pay the price! Because it takes a lot of time to make all of those Lego bricks!

More Lego Cake Ideas

If you are wondering whether you want to make a Lego cake or not, let me suggest some alternative ideas. You may remember that I like to use toys for cake toppers sometimes, and my kids love it. Why not use a large LEGO baseplate, set it right on top of the frosted cake, and then set a new boxed LEGO set on top of the base plate? Or build something on top of the base plate, like your child’s name, or the number they are turning.

For example, take this number idea and instead of hanging it, lay it flat on top of your cake.

I hope that you have enjoyed seeing how I made these Lego Cake Ideas. Be sure to check out some of my other Cakes, too!

Lego Birthday Party ideas

Well, what is a post on Lego cake ideas without including some of the birthday party ideas, too?

• Sometimes you can find Lego brick tablecloths, paper plates, and napkins at the dollar store.
• You can build the birthday boy’s name in Legos.
• For an activity, you could let all of the birthday guest kids build their own names out of Legos.
• Lego shaped candy, whether hard or gummy, is always a hit. I think my kids like the gummy lego candies the best.
• You can make your own Lego shaped treats using marshmallow fondant.
• You can build a Lego scene to go with the birthday cake for extra impact.
