LEGO cake in three layers for boys' birthday party

A former colleague of mine, Helene, sent me a message with a link to an amazing LEGO wedding cake (https://www.facebook.com/pages/Cupcakes-by-SJ/554669104671327?fref=ts) with the words: 

“Next project?”

It turned out that her boy, Oliver, and his best friend, Dines, was to celebrate their 6^th birthday together, and Helene jokingly “ordered” a cake similar to the one made by Cupcakes by SJ but modified to serve 20-24 people and be suited for a boys’ birthday party.

She’s perfectly aware that I only make cakes for the fun of it (and don’t take orders), but a challenge is a challenge, and after all I am on leave….

I tried to by square baking trays at http://www.frederiksbergkoebmanden.dk/, but the ladies there were busy chatting with each other and didn’t seem interested in providing any help or guidance, so I opted for using my existing baking trays…. 

The cakes was baked in three round trays (10cm, 18cm and 26cm) and consists of:

600 gram of caster sugar beat with 10 eggs (until white). Add 600 gram melted butter.

Stir in 600 gram of flour + 4 teaspoons baking powder + 6 teaspoons of cocoa and 300 gram finely chopped dark chocolate.

Bake for approx 50 min. at 200 degrees preheated oven.

When the cake comes out of the oven, turn it upside down on a tray, soak in neutral syrup (sugar and water boiled to a syrup) and cover the whole thing in cocoa/butter cream.

The cake was covered in white fondant and the LEGO pieces were made out of coloured fondant (using a straw to make the little knops). All in all a kilo of fondant was used for this cake.
