Not only is this cake a fun and unique way to celebrate a birthday, but it’s also easy to make and can be customized to suit any LEGO fan’s tastes. So, without further ado, let’s get started on making a Simple DIY Lego Birthday Cake!


  • 2 boxes of cake mix (flavor of your choice)
  • 4 cans of frosting (color of your choice)
  • 1 bag of LEGO bricks (small size)
  • 1 LEGO minifigure (optional)
  • Wax paper
  • 1 cake board or large plate


Step 1: Bake the Cake

Start by baking your cake mix according to the instructions on the box. You can use any flavor you like, but we recommend using a vanilla or chocolate cake for a classic taste. Once the cake is done, let it cool completely before moving on to the next step.

Step 2: Cut the Cake

Using a sharp knife, carefully cut the cake into the shape of a rectangular LEGO brick. You can use a real LEGO brick as a template, or freehand it to create your own design. Make sure the edges are straight and even for a clean look.

Step 3: Frost the Cake

Open your cans of frosting and mix them together to create the color of your choice. We recommend using bright primary colors to stay true to the LEGO theme. Spread a thin layer of frosting over the entire cake to act as a crumb coat. Let it set for a few minutes before adding a second, thicker layer of frosting.

Step 4: Add the LEGO Bricks

Open your bag of small LEGO bricks and sort them by color. Then, use them to create a pattern or design on the top of your cake. You can create a simple brick pattern, or get creative and make a specific LEGO set or character. For an extra touch, add a LEGO minifigure to the top of the cake.

Step 5: Transfer the Cake to a Cake Board or Plate

Cut a piece of wax paper to the size of your cake board or plate. This will help prevent the cake from sticking to the board or plate. Carefully lift the cake off of your cutting surface and transfer it to the cake board or plate. Smooth out the frosting with a spatula and remove any excess wax paper.

Step 6: Serve and Enjoy!

Your Simple DIY Lego Birthday Cake is now ready to serve! Cut it into slices and enjoy the sweet taste of celebration. Don’t forget to take a picture before serving, so you can remember the fun and creativity that went into making this special cake.
