Lego Cake

In the months after finding out I was pregnant, I naturally thought a lot about the future things I would get to do for my child. One thing I was excited to try is fun birthday treats. Our families aren't huge on the enormous birthday parties, but we do celebrate as  family and have birthday treats each year. I had pictures in my head of learning how to make the fun ruffled iced cakes, pretty pies, and elegant desserts. And then we had a boy and I realized, he probably won't want pretty desserts, he's going to want dinosaurs, dirt cakes, monsters, lizards, etc. While they aren't "pretty", I realized that those are going to be fun to make too. So when Lou sent in her Lego Cake Pinstrosity, I had to put that on the list of future birthday treats to try out. I may be trying it out sooner than I think though; Cameron just saw the picture and said "I want a Lego cake!". I love this man. So for his birthday in 6 months, maybe this is what I should make him. Cameron's 31st Lego Themed Birthday. This'll be awesome.

The Original Pin

See? That's a fun cake! And it looks deceptively easy. Lou said, "Our oldest son turned 11 years old (on the 11th of August).  He is majorly into Lego's so of course he wanted a Lego shaped cake.  I have tried a few things on Pintrest that have been quit successful (shelves, cookies in a jar, scrapbook ideas, etc).  I saw an adorable cake and thought to myself "I can totally do that!"  Well, I attached two pictures proving how I could not totally do it....... Although all three of my boys said it tasted amazing."

The Pinstrosity

It does look like a Lego, but maybe one that's lived out in the yard too long and has had too much sun and sand. The basic anatomy of a Lego is there, but it just needs a little refining to make the Legoness pop.

First, the block shape. The instructions have you cut the top of the cake off so that it is completely flat. This will help tremendously!

Next, the frosting. The instructions have you frost the cake, then freeze it, and frost again while the cake is frozen to seal in the crumbs. I know, if you are like me you don't want to take the time. If you are particular about the look though, you'll want to do a crumb coat.

Third, the lego studs. I almost called them posts, but I didn't know if that's what they were really called, so I had to go look it up. The sticky-uppy parts of the Lego blocks are called studs (did you know the machines that make Lego's have a precision tolerance of 2 micrometers...they have to get things pretty precise to ensure the blocks all fit together properly). Now that you have that piece of trivia to share around the dinner table, I'll proceed. The studs in the original pin were created by cutting large marshmallows in half and frosting them. My thoughts were, "Why not just use mini cupcakes. Those look like the right shape and size." And it looks like maybe that was Lou's thoughts as well (or maybe I'm seeing crumbs from the actual cake stuck on the frosting...not sure). As I think about it though, marshmallows will give a more accurate shape and they might be easier than cupcakes.

Fourth, the coloring. This recipe called for the pre-colored gel frosting, which is already vibrant and ready to use. If you don't want to use that, and want to color your own, you need to use cake/frosting specific colorings. The normal food color many people have in their cupboard just won't cut it (and will change the texture of your frosting...learned that one the hard way).

So there you have it! Lego cake! If I had some of that on hand, I think that'd be my breakfast. You can't go wrong with cake, frosting and marshmallows!


  1. I made this cake rather successfully. I did 4 legos in different colors (I used white, dark blue, dark green and yellow) -- and yes, it was for an adults party. Cutting the marshmallows in half is the way to go. I also found that the easiest way to ice the cake was to ice the cake without the marshmallows and get your nice sharp lines. Then ice the marshmallow halves separately and place them on the iced cake.

    Also, refrigerating the marshmallows before icing them made them harder and therefore easier to ice. I used a fork to hold the marshmallow from the bottom, iced the top and then did a ring around the side.

  2. Also, having the sharp square or rectangle lines for this cake is a must. I also recommend a "crumb coat" to prevent the cake pieces showing as in the picture. Do a very thin icing coat over the cake (crumbs done matter in this coat), refrigerate and then you can do a nice clean easy-to-apply layer of icing without worrying about crumbs. It's like paint primer but for cake.

  3. Um...Boys can like "pretty things" and girls can like "dinosaurs, dirt cakes, monsters, lizards."

    1. Of course boys like pretty things, they marry us! ;)
      She never said they can't. What she DID say "he probably won't want pretty desserts", not boys don't want pretty desserts.
      I don't have boys, but I have two teenage/ young adult girls who would probably really like this cake. As well as liking Disney (yes, at their ages) and other traditionally "girly" things, they also love Star Wars, Transformers, Batman, Marvel Superheroes (especially Thor) and other traditionally "boy" things. One had a cake that looked like a dirty cat pan once. (The theme was Fear Factor and the cake was the final challenge!)

      For the record, I totally support the having cake for breakfast idea!!!!! :)

  4. I also successfully made this cake. It is all about the crusting buttercream. It has to be the right thickness. I would not try it with store bought icing. And the cold cake/marshmallows are important.

    1. This is definitely a cake you need to make your own frosting for (I never use store bought frosting). Homemade frosting is easy to make and can easily be thickened or thinned as needed. I always do a crumb coat and refrigerate or freeze for 30 mins and then frost. Cakes should always be made at least the day before so you have time to play with everything.

  5. I just did a cake similar to this for my son's 6 birthday cake. Only i took a mini loaf pan and made several bricks. I did the crumb coat and actually froze my cakes. I used peanut butter m&m's for the studs. It turned out cute. Not professional but cute.

  6. I just made two of these cakes for my son's birthday in June. Turned out great :) Freezing is definitely the key. But I made the studs with Oreos! So much easier to frost than a cupcake or a marshmallow. :)
