Ingredients

For the cake

  • 500 g Butter or baking spread
  • 500 g Caster sugar
  • 9 Eggs large
  • 3 tsp Vanilla extract
  • 500 g Self raising flour
  • 75 g Sprinkles

For the buttercream

  • 900 g Icing sugar
  • 450 g Butter
  • 2 tsp Vanilla extract
  • 2-3 tbsp Milk

For decoration

  • 25 g Sprinkles

Instructions

  • Pre-heat your oven to 160C Fan/180C/350F/Gas Mark 4, and grease and line three 8" cake tins (that are at least 2" deep)
  • Mix together the butter and the caster sugar until smooth
  • Add the eggs, two at a time, and mix between each addition
  • Then add the vanilla extract, and whisk in the self raising flour
  • Fold in the sprinkles
  • Divide the mixture equally between the tins
  • Bake the cakes for 35 minutes or until a skewer inserted in the middle comes out clean. Remove from the tins and leave them to fully cool on cooling racks
  • To make the vanilla buttercream mix the butter and icing sugar together. Once it starts to come together add the vanilla extract and milk, and mix until smooth. I use my electric hand whisk to do this but you can also do it by hand with a spoon. If the buttercream is too stiff, add more milk
  • If the cakes have domed on top, level them off with a cake leveller or a serrated knife
  • Stack the cake layes, piping or spreading buttercream between each layer
  • On the final sponge, smooth icing over the top and smooth it out using a palette knife
  • Then use a piping bag with a star nozzle to pipe swirls around the edge and fill the middle with more sprinkles!
  • Leftovers will keep in an airtight container in a cool place for 2-3 days

Notes

For a two layer cake, use 335g of butter/caster sugar/self raising flour, 6 eggs, 2 tsp vanilla extract and 50g sprinkles. For the buttercream, 230g butter, 460g icing sugar and 1 ½ tsp vanilla extract. Plus a little milk if the buttercream is too stiff
For a one layer cake use 175g of butter/caster sugar/self raising flour, 3 eggs, 1 tsp vanilla extract and 25g sprinkles. For the buttercream, 115g butter, 230g icing sugar and 1 tsp vanilla extract. Plus a little milk if the buttercream is too stiff
