This kid’s chocolate building site birthday cake looks great and is very easy to put together!
It was my elder son’s 5th birthday recently. It’s taken me a while to blog about this cake, but if you follow my posts you’ll probably already know I gave birth to our second son at around the time of my first son’s birthday and since then I’ve been a tad busy!
As I knew my sons’ birthdays would be very close together, I wanted to make a birthday cake which was simple and quick to assemble. Some internet browsing brought me to this building site / digger cake idea in the form of some photos. I did my best to copy what I saw, using my own cake recipe and various toy construction site pieces I already had.
Making the cake and buttercream
I used my most reliable chocolate cake recipe. You can find a full description of how to make the two circular chocolate cakes you’ll need for the digger cake in my Double Chocolate Easter cake post.
Alternatively, you could also use my chocolate fudge cake recipe.
Both these recipes also tell you how to make chocolate buttercream.
Assembling and decorating the digger cake
Clearly, you’ll need some plastic toy building site pieces to make this cake! I was lucky to already have the digger, cement mixer, cones etc. I gave them a good wash to make them food safe before putting them on the cake. I’m sure you can find things like this to buy online.
Stack your circular chocolate cakes on top of each other on your cake board, sticking them together with a layer of chocolate buttercream.
Cover about half of the top of the cake, towards the “back” of the cake, with chocolate buttercream. This will be the “muddy” area where the digger will sit.
Carve away a small part of the top and front of the cake to look like dug earth. Start small and then you can use a spoon or fork to crumble away part of the side of the cake. Leave some of the “earth” crumbs on the cake board.
Stick chocolate finger biscuits around the edge of the cake using another layer of chocolate buttercream as edible glue. More guidance about how to do this can be found in my chocolate finger cake post, but it’s honestly as straightforward as it sounds. I used Cadbury’s chocolate fingers, but I’ve also seen pictures of this cake where KitKats have been used. Cut the finger biscuits which will border the “dug earth” at the front of the cake down to size before sticking them in place.
Sprinkle some mini Smarties (M&Ms or similar would also be fine!) on the dug earth sections of the cake.
I made a small Happy Birthday sign from some card, fixed three wooden skewers on the back with sticky tape (toothpicks would also work), and stuck it into the back of the cake.
Once I had all the pieces ready, it took ten minutes to assemble and my son was delighted with it. I just wish I could make it every year!
I’m sorry if my explanation as to how to assemble this kid’s chocolate digger birthday cake isn’t very clear. If you have any questions, please ask in the comments below! 🙂
