Funfetti cake – How to make a sprinkle cake:
Preheat the oven to 160C, gas 3 and grease and line the tins with greaseproof paper. Beat the butter and sugar with an electric whisk until light and fluffy (about 8 minutes). Sieve the flour into a separate bowl. Add the eggs one at a time with 1/5 of the flour, beating until just combined, no longer, or the batter will be greasy.
Add the vanilla and fold through the batter with a large metal spoon or spatula. Divide the mixture between the two tins and bake in the oven for 55 minutes (this will depend of your own oven), removing it from the oven when it’s a golden colour and when the cake has shrunken away from the sides of the tin.
Leave the cakes to cool in the tins for 30 minutes before moving them to a wire rack to cool completely. When the cakes are completely cool, you can slice each cake in half. Using a large bread knife, trim the tops off the cakes and cut each cake in half. Add two cocktail sticks in the same place in the top and bottom slice of the cake. This helps you reposition the cakes to the original cut when you re-assemble the slices.
Make the buttercream by beating the butter with your electric whisk. Push the sieved icing sugar in by hand (as this saves some of the mess) and add 2 tbsp boiling water and your vanilla. Beat the buttercream for about 10 minutes, then it should have a lovely smooth consistency.
Add a blob of buttercream to one of your cake cards and stick the first layer to the card. Always keep the flattest sides (usually the bottom) of the cakes to the top and bottom. Add a couple of spoons of buttercream to a piping or sandwich bag, snip a small corner off (away from the cake so you don’t lose the corner in the food) and pipe around the outside edge of the sponge. This will just stop the jam coming out of the sides of the cake when you’re icing it.
Add jam to the middle of your cakes, adding the layers, using your cocktail sticks as a guide so you get a nice even cake.
Add a layer of buttercream to the whole of the cake and pop the other 6 inch cake card to the top before refrigerating for 1 hour to harden the first layer. When the first layer is set, add another layer.
Add the sprinkles to a roasting dish as this will stop some (not all!) of the mess.
Now for the tricky bit! Pick the cake up using the cake cards and roll the buttercream into the sprinkles. At this point, it’s really handy to have a helper shake the dish for you so you get an even amount all the way around. If you don’t, just pop the cake down each time or spread them on by hand, patting handfuls where you need it. Fill the gaps by hand.
Finally, using a large palette knife, remove the card from the top of the cake. This might pull some of the icing away as you do it but just fill it in with a fresh bit and pour the sprinkles over the top. You can use the tips of your finger to move them around and create a sharp edge.
There will be sprinkles everywhere but you are certain to wow your guests with this one, so it won’t matter. Now, simply slice your funfetti cake and serve!
