This amazing Star Wars Death Star cake looks super impressive but is easier to make than it looks! Make this fun cake the centrepiece of your Star Wars party food table!
I made this Death Star cake last summer for my Star Wars mad 7 year old, and today I've finally got around to sharing the recipe and step-by-step decorating instructions. I think this might be my favourite cake that I've ever made, and six months later, he's still talking about it so I call that a massive win!
This is quite a mammoth recipe post, but despite the long list of instructions it's actually a pretty easy cake to make, you just need a little time and patience!
I took inspiration for the decoration of this cake from Cake Whiz's amazing Easy Star Wars Cake and adapted the cake recipe from Veena Azmanov's Sphere Cake Recipe for the chocolate cake inside.
Before I share the recipe, I must mention the cake light! I don't know how long these have been around, but I discovered them when I was searching for cake inspiration last year and I just HAD to give them a go! They are little round LED lights that you can build into your cake creations and the ones I bought (from eBay) had the option to order little cups that you can sit them in, which made it really easy to position the light exactly where I wanted it in the cake.
I did my research and checked the correct colour of the Death Star Laser (green!) but you can of course use any colour you like.
Star Wars Death Star Cake
Ingredients:
For the cake:
- 220g softened butter
- 280g golden caster sugar
- 4 large eggs
- 240g plain flour
- 50g cocoa powder
- 1 Tbsp baking powder
- 150ml milk
- 2 tsp vanilla extract
To decorate:
- 250g butter
- 500g icing sugar
- 2 tsp vanilla extract
- 500g grey fondant icing
- silver edible lustre spray
- white sugar pearls
Equipment:
- 1 or 2 x 18cm sphere cake pans
- green cake light - I bought a set from ebay and they came with little plastic cups to help place them in the cake.
Method:
First make the cakes. I suggest making them the day before decorating to ensure they are fully cooled.
Preheat the oven to 160°C (Gas mark 3/320°F). Grease the sphere pan(s) really well and line with a couple of strips of baking paper to help you remove them from the pans.
Important: If you only have one pan, I recommend halving the recipe ingredients so that you can make and bake each cake individually.
In a large bowl, whisk together the butter and caster sugar. Add the eggs, two at a time, whisking after you add each pair.
Once the eggs have all been whisked in, sift in the flour, cocoa powder and baking powder, along with the milk and vanilla. Whisk again until fully combined.
Divide the cake mixture between the two greased sphere pans.
Place in the centre of the oven and bake for 40-50 minutes until cooked through. Check that the cakes are cooked by pushing a skewer into the thickest part of the cake - once cooked the skewer should come out clean when removed from the cake. You may need a bit more or a bit less time depending on your oven.
Once the cakes are cooked, remove from the oven and leave in the pans for 15 minutes to cool. This will help you to remove the cakes without sticking. After 15 minutes, carefully run a knife around the edge of each cake, then gently tip each cake out onto a cooling rack. They should just pop straight out. Carefully remove the strips of greaseproof paper and leave to cool completely before icing.
To decorate:
Whisk 250g butter until soft and fluffy. Add the icing sugar, a little at a time, whisking as you go until completely combined. Add the vanilla extract and whisk again.
Split the buttercream into two portions - one for filling and one for covering the cake. Split each semi-circle cake and fill with the buttercream.
Using a round cookie cutter, mark out a circle in the top of one of the cakes.
Carefully remove the small circle of cake to form the concave base of the laser gun.
Stick the two halves of the cake together with buttercream, with the circle cut-out on the top, then place on a cake stand or board.
Cover the whole cake with the remaining buttercream. I used a pallet knife to help spread it around evenly.
Roll out approx 350g of the fondant icing and use to cover the cake. If it breaks or cracks in places, don't worry too much - you can cover any blemishes in the next step! Trim off any excess fondant and remove, then tuck the edges under the bottom of the cake.
Roll out the remaining fondant icing. Using a large round cookie cutter, slightly larger than the one you used to cut out the laser gun base, cut out a circle of fondant. Decorate it by gently scoring with smaller round cookie cutters and a knife tip.
Cut a tiny circle from the middle, then push in the little light cup holder - I've flipped it over in the photo below so you can see how it fits in.
Place the decorated circle of fondant, complete with light holder, in the concave round hole on the top of the cake.
Cut rectangles from the remaining fondant and decorate by scoring lines and little circles, using a tiny circle cutter or the end of a drinking straw.
Decorate the whole cake with the rectangles, making sure you cover up any cracks in the fondant icing base! If the icing is starting to dry out, you can stick them in place by brushing a little water on the backs. As you can see in the photos, I used the circle cutter to cut curved pieces from the rectangles to help them fit neatly around the laser gun area.
Spray the whole cake with the silver edible lustre spray. This step really made the cake shine, so if possible, don't skip it!
Press sugar pearls all over the cake to look like the lights of the death star. I took care to place them in the circles I had already marked on the cake.
Finish the cake with the cake light - turn it on first then pop it into the holder in the centre of the laser gun that you prepared earlier.
Serve and enjoy - may the force be with you!
