Equipment

  • 4 x 8-inch cake tins
  • Mixing Bowl
  • Electric Mixer
  • Spatula
  • Wire Rack

Ingredients
  

For the Sponge

  • 400 g salted butter room temperature
  • 400 g caster sugar
  • 8 large free-range eggs
  • 3 tbsp vanilla extract
  • 400 g self-raising flour
  • 90 g colorful sprinkles

For the Buttercream

  • 500 g salted butter room temperature
  • 1000 g icing sugar sifted
  • 3 tbsp vanilla extract
  • 2 dashes milk

To Decorate

  • 120 g pastel sprinkles
  • a few drops pink food coloring

Instructions
 

  • Preheat oven to 170°C (150°C fan). Grease and line four 8-inch cake tins and lightly dust with flour.
  • Cream butter and sugar until light and fluffy, about 3–4 minutes.
  • Add eggs one at a time, mixing well. Stir in vanilla extract.
  • Fold in flour in two batches, then gently stir in the colorful sprinkles.
  • Divide batter evenly among tins and bake for 30–35 minutes or until a skewer inserted comes out clean.
  • Let cakes cool completely. Chill layers for easier assembly if desired.
  • To make buttercream: Beat butter until pale, gradually add icing sugar, vanilla, and milk. Tint half pink.
  • Stack cake layers with buttercream in between. Apply a crumb coat, chill, then apply final coat and decorate with pink frosting and pastel sprinkles.

Notes

Use room-temperature ingredients for the best texture. Chill before slicing for clean edges. Customize with different sprinkle colors or frosting shades.
