An Amazing Lego Cake {My Little Boy is 5!}

If you’ve been around for a while, you know that I always try to give my kids exactly what they want in a birthday party.  I didn’t have many parties as a kid, and awesome parties (within reason) are something I’ve always tried to provide.  This year, the boy had two simple request… 1) a sleepover and 2) a Lego cake.

My boy isn’t like my girl, not at all.  He’s much happier at home, playing in the dirt or watching a movie, than he is concentrating on an activity.   With that in mind, we decided to keep the party low key – just a few boys, carryout pizza and an awesome Lego cake.  After some research on Pinterest and meshing a few ideas together, my sister put together this awesome construction themed Lego cake:

Lego Construction Cake Tractors - MamaMommyMomThe tiny machines are all parts of Lego sets assembled by yours truly, and the crane (the working, remote control crane) was an on hand item that the boy got for Christmas from Santa (I have it on good authority that Santa acquired said crane on Amazon at a very reasonable cost.)  The Lego bricks are all made of homemade marshmallow fondant, layered over a delicious vanilla cake.

The crane was cool… all of the kids got a huge kick out of it.  Truth be told, so did I!  We lowered his candle, untied it and lit it for him to blow out.  I even made a video of the crane in action to share with my friends on Facebook

What do you think? Is that a cool Lego cake or what?  I hope you share this with your kiddos or any of your friends who have Lego loving kids.  It was a truly awesome cake and something simple enough anyone could make their own version at home.

  1. This lego cake is pretty awesome. My son is 12 and LOVES legos so something like this, but maybe with Star Wars theme instead of construction would make him a happy camper. Definitely pinning to refer to later!

  2. This cake is AWESOME! LC had a LEGO party for his 3rd birthday and we did cake pops, but something tells me every little man would LOVE this cake!! So cool and clever!

    A bit of a detailed question, but would mind providing more detail on how you made the Lego bricks? I do work with fondant, but I am not an expert. Did you use a mold? Hand-shape? My son sounds a lot like yours and is having a Lego bday party later this month. We also happen to have the crane, so I think this cake concept will be perfect.

      The blocks were hand shaped. You can use the end of an icing tip to cut the small circles for the top. 🙂 It was definitely a fun cake and everyone loved it!
