Mars Planets Mud Slide Giant Cupcake

Stuck for a common theme for two friends’ joint birthday this week, I decided to dig out my “Big Top Giant Cupcake Mould” Christmas present and give it a whirl. A little apprehensive about using it for the first time as getting the measurements right for American moulds is always a little tricky, I was relieved when I struck gold first time with this recipe! I’ve had loads of amazing feedback from this cake and so on Good To Know Recipes‘ request I have decided to share my secret with you!
And so here it is…a little time consuming but definitely worth giving a go if you fancy a weekend baking challenge! There are several different giant cupcake moulds out there but I have used a Big Top Giant Cupcake silicone mould with the filling insert.
Ingredients
for the cake batter
250g self-raising flour
1½ tsp bicarbonate of soda
3 tblsp cocoa powder
220g caster sugar
220ml vegetable oil
220ml milk
3 medium eggs, lightly beaten
3 tblsp golden syrup

for the buttercream
160g unsalted butter softened
500g icing sugar, sifted
2 tsp vanilla extract
3 tblsp milk

for the ganache
150g dark chocolate
150ml double cream

to decorate
Mars Planets
cocoa powder

Method
  • Preheat the oven to Fan 160°C and grease the inside of your giant cupcake mould with vegetable oil.
  • In a large bowl, sift together the flour, bicarbonate of soda and cocoa powder.
  • Stir through the caster sugar until evenly combined.
  • Mix together the liquids: oil, milk, beaten eggs and golden syrup.
  • Make a well in the centre of the dry ingredients and pour in the wet ingredients.
  • Using an electric hand whisk, beat together the wet and dry ingredients until evenly blended and smooth, scraping down the sides of the bowl as you go.
  • Once smooth, pour the batter into the greased mould so that it fills about 3/4 of the way up the mould. Secure the filling insert on top of the bottom half.
  • Bake in the preheated oven for 45-50 minutes until well risen and a skewer inserted into the middle comes out clean. The time will completely vary on your oven so after 45 minutes, keep checking every 5 minutes until it is cooked through.
  • Once cooked, cool on a wire rack for 5-10 minutes before removing the silicone mould and leaving to cool completely on the rack.
  • Meanwhile make the buttercream by creaming together the butter, icing sugar and vanilla until combined. Add the milk a tablespoon at a time and continue beating for a few minutes until the buttercream reaches a light and fluffy consistency.
  • To make the ganache, chop the chocolate into small chunks and place in a medium sized bowl. In a small saucepan bring the cream to the boil before whisking onto the chocolate. Continue whisking until all the chocolate is melted and you have a smooth silky ganache.
  • Once the cake is cooled, you can begin to assemble it. Start by trimming the bottom side of the top half so that it is flat and will sit flush on top of the bottom half.
  • Place a blob of ganache on a cake board and place the bottom half of the giant cupcake on top. This will glue the cake to the board.
  • Once the ganache has cooled to a spreading consistency, spread it onto the bottom half of the cupcake using a palette knife.
  • Now spread a thick layer of ganache on top of the bottom half as the first layer of filling. Place a handful of Mars planets on top of this followed by piping a layer of the buttercream.
  • Now place the top half of the giant cupcake on top of the filling.
  • Take the remaining buttercream and starting from the bottom where the two layers meet, begin to pipe the buttercream around the cupcake in a continuous swirl as you would ice a normal sized cupcake, finishing at the peak. Put the cake in the fridge for 5 minutes to harden slightly.
  • Dip the bottom of the ganache bowl into some hot water to loosen it and whisk until you have a thick pouring consistency. Remove the cake from the fridge and pour the remaining ganache over the top of the cupcake to provide your mudslide.
  • Decorate with as many Mars Planets as you desire and finish with a generous dusting of cocoa powder.
