Lego Man Birthday Cake

 In Recipes

We had another birthday in the house this weekend, that meant I was on cake duty. With our youngest turning 6 I felt like a Lego Man cake was the perfect theme this year. Read on to find out how easy it was to make this fun and cute cake!

What you’ll need:
  • Frosting -buy a couple cans or whip up your own.
  • 9×13 baked cake -we’re a chocolate household; I ended up using the same recipe from my Magic the Gathering cake post.
  • Food coloring -I used Wilton’s color gels since I like the vibrant colors they produce.
  • Fondant (optional) -fondant will give your cake a cleaner, more professional look. It’s also easier to do detail work with the stuff. We don’t care for the way it tastes though, so I just used straight up frosting.
  • Lego man template -sketch out your own or use the one below, that I modified from an online image.

  1. Bake your cake in a 9×13 pan according to its instructions. Be sure to grease and flour your pan for easier removal after cooking.
  2. Once your cake has cooled for 20 or so minutes remove it from the pan and place it in the freezer. Cooling your cake will make it less crumbly when you cut the Lego man out.
  3. Print the Lego man template out to scale (my cake was roughly 12.5 inches in height) and cut it out.
  4. Pin your template in place using a toothpick and cut the cake. Go slow and smoothly to prevent the cake from ripping and turning to crumbs.
  5. Position your Lego man on a tray and frost it with colored frosting. Remember I like to use ziplock bags to mix my frosting and the colored gel. I then snip the corner and pipe it on, then finally smooth it out with a cake spatula.

Tips & Tricks

  • You may want to build and frost your Lego man once piece at a time; I would especially recommend this if you’re using fondant. Some of the spots were difficult to get at with a spatula after my Lego my was assembled (between his arms and torso). I actually used a bamboo skewer to frost the inside U of the hands.
  • Be careful with the hands. My first hand completely crumbled and had to be redone. The other hand survived, but started to cave in and fall over. When I redid the one hand, I used slightly dried up cake since it better supported itself.
  • I would recommend cutting and frosting your cake during one sitting. This will help prevent all the moisture from escaping.
  • Have fun -there are so many different directions you can take this cake given the endless varieties of Lego figures out there!
