This is one of the simplest cakes I’ve made, but a very effective one! The only tricky part is getting your smarties to line up across your fish but I know for a fact that mine went a bit squiffy and you can’t tell when you are standing away from it.
You just need one sponge cake for this as it’s a one layer thing. I used my basic chocolate sponge recipe for this cake and it worked perfectly in my 20cm tin.
For the cake:
170g caster sugar
115g self-raising flour
3 medium eggs
55g cocoa powder
For the buttercream:
110g butter (room temp)
170g icing sugar
55g cocoa powder
1-2 tbsp milk
For the decoration:
White ready to roll icing
Butter your tin and preheat the oven to 180c/160c fan oven/Gas 4.
Beat all the ingredients together adding a drop of milk if the mixture is too thick. The mixture should drop off your spoon when tapped gently so keep gradually adding milk until you get this consistency. Place the mixture into your tin and level out.
Bake for 20-25 mins until your sponge springs back when lightly pressed.
Leave to cool.
Whilst you are waiting for the cake to cool, open up your tubes of smarties and sort into colour. Doing this ahead of time will save you lots of brain ache when it comes to decorating the cake later on.
When the cake has cooled, cut out a slice. You want to imagine that your remaining cake will look a bit like pacman, so go for quite a chunky triangle. This will make up the tail and the empty space will be the mouth of the fish (clever, no?)
You then need to make up the buttercream by beating all the ingredients together. You want the buttercream to be fairly thick as it is going to act as the glue for your smarties.
Spread over your cake evenly.
Apply your smarties. As you can see, I went for two lines of each colour apart from at the end (who knew you get less orange and purple smarties?) and I tried to go in as straight a line as I could. It’s entirely up to you how you decorate it though. If you are making the cake with children it could be fun just to come up with your own crazy and colourful pattern.
To make the eye and the bubbles you will need to roll out some white icing and use a circular cookie cutter to make the circles. I placed a blob of buttercream on to hold them in place and also put a small amount on the green smarties to make the eye.
I didn’t attach the tail but simply sat it against the body of the fish.
Very simple, but very pleasing to the eye!
