Star Wars Lego Cake

I made this Star Wars Lego cake for a dear friend who requested the cake for her son’s birthday. 

This was not a very complicated cake to make, and the Star Wars character figurines on the cake were all toys which she provided. The rest of the decoration on the cake including the lego blocks and the light sabers were made of fondant. Even the Star Wars logo was cut by hand.


Her is How I Decorated the Star Wars Lego Cake

These were the main supplies I used in making the decorating this Star Wars Lego cake:

  • Cake – this was a 2 tier cake and one of it was a dummy tier. Since I decorated this quite a number of years ago, I cannot recall which tier was the real cake and which one was dummy. Nevertheless, the top tier measured 6 inches in diameter and the bottom tier was 9 inches. Each tier was 4 inches high. For the real cake, I used my chocolate cake recipe and it was filled and crumb coated with buttercream.
  • Buttercream – As I have mentioned earlier, buttercream was used as a filling for the cake and to crumb coat it.
  • Fondant – I used Satin Ice fondant to cover the entire cake as well as to make the fondant deco on the cake.
  • CMC - I added CMC into the yellow fondant I used to cut out my stars on the cake to make sure they harden quicker and hold their shape when put on the cake.
  • Styrofoam dummy – One of the tiers on this cake was a dummy (and I cannot recall which one of it was a dummy, sorry).
  • Round fondant cutters – I used 2 different types of round cutters. One was from a larger cutter set which I used to cut out the grey door on the second tier, while the other type I used were my small plunger cutter set which I used to cut the round dots on the lego blocks.
  • Star cutter – I used the star cutter to cut out the star toppers on the cake which held the birthday boy’s name.
  • Star Wars logo template – this was printed from the internet and I used it as a template to hand cut the star wars lego in yellow and black fondant.
  • Alphabet cutters – I used Clikstix block letters cutter to cut out the birthday boy’s name.
  • Star Wars character figurines – these were toy toppers and were provided by my friend to be put on the cake.
  • Fondant glue and shortening – there were the glue agents for this project. I used shortening for almost all the work except for the stars. I applied fondant glue to the wire before inserting into my fondant stars to hold them in place securely.


And this was how I put the Star Wars Lego cake together:

  • First on the list was getting the Star Wars lego template ready. I got this from the internet ( I resized it to fit the side of my cake before printing it out).
  • Next were the stars. I cut them out in yellow fondant using my star cutters. And I attached them to one wire each (the wires were dipped into fondant glue first so that it would hold the stars in place securely). And I left these stars to set and harden overnight.
  • As for the cake, once it was baked, as usual, I leveled, filled and crumb coated it with buttercream. And them I covered it with light blue fondant. I also covered the Styrofoam dummy tier at the same time. And then I stacked them.
  • Next was making the grey door. If you notice closely, the door has a marbled look and to make this, I kneaded white and black fondant together until just right to show the marble effect. If you knead too much, you will loose the marble effect and the whole thing will turn into a monotonous grey piece of fondant. I then rolled the fondant and cut it into a circle using my round cutter. And then, using my sugar craft knife, I marked vertical lines on it followed by one horizontal line right in the middle. I then used my black food marker to mark the horizontal line in black. I attached the door to the side of my cake with shortening, making sure it was positioned such that the vertical lines are really straight and the horizontal line is perfectly horizontal. Next, I added a small knob to the door using the remaining marbled grey fondant. Again, I used my craft knife to mark the lines on the knob and the black dot in the centre was marked with my edible food marker.  Once done, I attached the door to my door on the cake.
  • After the door, I went on to make and attach the Star Wars lego. To do this, I cut out the wordings first, attached them to a rolled black fondant piece with shortening and only then cut out the black fondant, closing following the wordings in yellow. And then I applied shortening to its back and attached it to the side of my cake. 
  • Next were the Lego blocks. I made them in red, blue and yellow. These were cut by hand and the round dots on them were cut using my round plunger cutter. The blocks that were attached onto the sides of the cake were made thinner than the ones I placed on the cake and the cake board. I let these blocks set first before placing them on the cake so that they don’t bend when slanted against one another. 
  • After that, I completed the cake borders. I used my extruder tool to piped out the rope border for my bottom tier and formed the round balls borders for the top tier by hand. All these were attached to the Star Wars Lego cake with shortening. 
  • As of the light sabers, I rolled some blue, red and green fondant into thin strips and then wrapped a thin piece of grey rectangle fondant on one end each. And I placed these on the front side of the cake, one on the top tier, one on the second tier and one on the cake board. 
  • And finally, before placing the toy figurines on the almost complete Star Wars Lego cake, I cut out the birthday boy’s name and attached each letter to my star toppers. I then attached the stars to the cake and adjusted the wire so that the stars are well spaced and in a curved position.

And that was how I decorated this Star Wars Lego cake.


Happy Decorating :)
