  • Beat in the eggs one at a time, ensuring each egg is fully incorporated before adding the next.

  • Gently fold in the rainbow sprinkles.
  • Divide the batter evenly between the two prepared cake tins.
  • Bake in the preheated oven for 25-30 minutes, or until a skewer inserted into the centre of the cakes comes out clean.
  • Allow the cakes to cool in the tins for 10 minutes, then turn out onto a wire rack to cool completely.
  • In a large bowl, beat the softened butter until smooth.
  • Gradually add the icing sugar, one-third at a time, beating well after each addition.
  • Add the vanilla extract and milk, and beat until light and fluffy.
  • Once the cakes are completely cool, place one layer on a serving plate and spread a thick layer of buttercream on top.
  • Place the second layer on top and spread the remaining buttercream over the top and sides of the cake.
  • Decorate with additional rainbow sprinkles.
