Instructions

1. Yellow cake
   Grease and line two 8-inch round baking pans with baking or parchment paper. Preheat oven to 180 C (350 F) standard / 160 C (320 F) fan-forced.
2. In a large mixing bowl, add butter, sugar and vanilla and beat with an electric mixer until smooth and creamy. Add eggs, one at a time, and beat after each addition.
3. Sift flour and baking powder. Add milk and beat on a low speed until combined. Add Greek yoghurt and mix through.
4. Divide the batter evenly between the two cake tins and bake in the oven for approximately 25-30 minutes or until golden on top. Carefully remove the cakes from the pans and set on a wire rack to cool completely.
5. Nutella frosting
   To make the frosting, place butter in a large mixing bowl and beat with an electric mixer on medium speed until pale and creamy. Add half the sugar and one tablespoon of milk and beat until combined. Add the remaining sugar and beat until smooth.
6. Add Nutella and another tablespoon of milk. Beat until smooth and creamy. If frosting is too thick, add an extra tablespoon of milk.
7. Generously frost the top of one cake layer. Add other cake layer on top. Frost top and sides of cake using a spatula. Add sprinkles.
