I made this for two of my friend’s birthdays, but I don’t think they minded sharing since it was an absolute monster of a cake. It’s really sweet so I’d recommend swapping the buttercream filling for something else if sugary is not to your taste. Bear in mind for the measurements below that I first weighed the eggs and then weighed the same amount of flour, sugar and butter so it depends entirely on how heavy your eggs are.
13oz self-raising flour
13oz caster sugar
3tsps baking powder
Vanilla bean paste
Chocolate extract (optional)
Red food colouring
Strawberry essence (optional)
Pick N’ Mix chocolates
In a large bowl combine the butter, sugar, eggs, flour and baking powder using an electric hand-held whisk until smooth.
To the first mixture add half a tsp of vanilla bean paste, and stir through until evenly distributed. Pour into the first tin.
To the second mixture add a large dollop of strawberry jam, a small drop of strawberry essence and some red food colouring. Adjust this depending on how pink you want the mixture. If this adds too much moisture then add a couple of spoonfuls of flour. Pour this into the second tin.
To the last bowl add a small drop of chocolate extract if you have it, and a couple of large spoonfuls of cocoa powder. You can add more or less depending on how chocolately you like your cake. Pour this into the third tin.
Bake all three in the oven for 30-35 minutes or until springy to the touch and a skewer inserted into the middle comes out clean. Cool on a wire rack.
Sift in large spoonfuls of icing sugar, adding small splashes of milk if the mixture becomes too thick. Add a small knob of cream cheese and mix until smooth.
Separate two largish blobs of icing into bowls. Add cocoa powder to one, and strawberry jam to the other.
Get a cake stand or plate and plop a little blob of icing into the middle to help keep the cake in place.
Add a couple of drops of vanilla extract to the remainder of the icing. Cover the whole cake, including the sides in the vanilla icing.
The next step is to cover the sides in rainbow coloured sprinkles, so that it looks like an ice-cream. I will admit that I had a bit of a ‘mare at this stage trying to figure out how to get them to stick to the cake. Chucking handfuls of sprinkles at it and hoping for the best is unsurprisingly not very effective. The best way I found was by using a palette knife dipped in hot water. Then put the hot knife into the tub of sprinkles and then smush into the cake. Do this all around the side of the cake (it takes a lot of sprinkles).
I found some little chocolate ice-cream cones in Wilkos which I used to decorate the top of the cake, but it would look lovely with anything.
