Baking hack Marshmallow Booster for domed cakes

Some times I make mistakes.

OK, OK I know I make mistakes all the time. But sometimes I make mistakes that require me to come up with a solution that ends up being kinda cool and worth sharing with everyone.

Like last Sunday, when I baked a packet mix cake and did not follow the instructions properly because I used a smaller tin, split the mix into 2 cakes and was lazy and did not line the tin as directed.

In my mind I was thinking that if I used two 6 inch tins I would end up with a lovely tall cake instead of a regular 8 inch flat cake. But at least 2 of those things I did wrong can result in the cake cooking quicker than usual which can mean overly domed (peaked) cakes.

And that is what happened, it was my fault - I know it - no use getting upset over it.

But I didn't want to cut off the tops to level the cakes, it was just too much to lose and it was too big a space to just fill with plain ganache, so I came up with this marshmallow booster cake hack idea.

I placed the cake flat side down on my cake stand, put a thin layer of chocolate ganache over the domed top of the cake and then stuck a ring of marshmallows around the edge of the cake. Then I filled in the rest with ganache* and squished them together with the other cake flat side on the top. I chilled the cake for a bit and then covered the sides and top with the remaining ganache using a kitchen knife.

*to make ganache melt 2 parts chocolate to 1 part cream (so for example 200g (8oz) chocolate to 100g (4oz) cream) in the microwave at high heat for a minute leave to rest and then whisk until smooth. Heat another minute or 2 if the mixture is not smooth and then whisk again.

I decorated the top with some raspberries but you can do what ever you like.

It was a pretty good save if I do say so myself, the marshmallows are more economical than chocolate and not as heavy and dense, plus to the kids it seemed like I was doing something exciting.

Hope you enjoyed my cake fail. We all did :)
