If you are a follower on my Instagram page, you have probably seen quite a few pictures of this LEGO cake! I had such a fun time making this for a little one’s birthday party. Cute and fun, they will all love this diy LEGO block cake.

DIY Lego Cake

Having a little guy in the house turn six years old, and a LOVER of Legos had me thinking that I needed to make him a Lego cake. I immediately ran over to Pinterest. It was a fun search, but there was nothing that really hit what I was wanting to create. I decided to take some bits and pieces from different cake ideas and with the help of my mom, we came up with this fabulous DIY Lego Cake.

After we had our cake pan set, we set out to make the cake. Here is what you will need on hand before starting:

DIY Lego Cake

  • 3 white cake mixes (and ingredients needed for those)
  • Wilton 9 x 2 Checkerboard Cake Pan Set
  • food coloring in red, greed, and blue (we used the paste)
  • Wilton Spray & Seal
  • a good buttercream frosting
  • fondant (Yellow, Red, Green, and Blue)
  • A few Legos (little people and blocks)

Making your LEGO Cake

Make your three cake mixes and place them in separate bowls. Add your color paste a little at a time until you get the color you are looking for. I wanted bright Lego colors, so my batter is awfully bright! (In fact, the green really reminded me of the Nickelodeon Slime!

Lego Cake batter

I found the best thing to do was to make the cake the day before you do the icing. It will make things a lot easier. I created a diagram below of how I made these cakes once the cake batter was made and the dye paste was added.

Once the cakes were allowed to cool, I took a serrated knife and cut rounded portion of the tops off. I wanted my cakes to be able to be as straight as possible for the finished product.

Since you are using a  buttercream frosting before placing on the fondant, you will end up picking up crumbs from the cake. I have found that the Wilton Spray and Seal is perfect to keep those crumbs at bay and help make frosting a cake easier.

Making the LEGO Cake

Once our cake was covered with buttercream frosting, it was time to add on the fondant and make the cake!

I used a ruler to determine the height of my cake. I then rolled, measured, and cut a strip of yellow fondant to cover the sides of the cake.

Now here comes the fun part! Making all of those little Lego blocks for the cake. Just simply roll the different colors of fondant and then using an actual LEGO block (like a cookie cutter) I stamped the Legos into the fondant. I then used a small knife to finish cutting around the edges and set the blocks aside.

Once I had all of the blocks created, I just simply started laying them out in a pattern on the top of the cake and stuck with that same pattern all the way on top.

Lego Cake Start

Once I was finished with the top, I add a little blue border on the bottom. I filled in any extra areas on the top, and then added a few Lego blocks of fondant around the sides of the cake.

I found that the construction guy was the best fit for the top of this cake, because it was indeed a construction project!

Sorry I don’t have the normal step by step pictures, but I was honestly not going to make this a post until a lot of friends and family suggested I should share the steps. Just in case anyone else wanted to try their hand at making one.
