Preheat oven to 170°C and butter and line 3 x 21 cm cake tins with paper.
Place butter into the Thermomix bowl and mix 40 sec/50°C/speed 4. This will soften the butter, but not melt it.
Add yoghurt, milk, vanilla and eggs and mix 20 sec/Butterfly/speed 3.
Add sugar, flour and baking powder, bicarb soda and salt. The bowl will be very full, so use the spatula to stir through some of the batter before mixing 10 sec/speed 3.
Scrape down sides of bowl and mix 30 sec/speed 3.
Divide batter into three equal amounts and add in the flavours for each layer, stirring in with your spat-ooh-lah-lah until well combined. Pour each into prepared tins and tap gently to level tops of cakes.
Bake for 40-45 minutes until golden and springing back to the touch. Cool for 15 minutes in the tin before removing from tins.
Cool completely before finishing cake as directed.
Layer the cake using a double batch of the Chocolate Ermine Frosting in between each layer and you can naked frost it or go full on like we did. Don’t be afraid to use plenty of frosting.More is always better. Decorate the top of the cake with flowers, chocolate curls, Easter eggs, a dusting of cocoa or whipped cream rosettes.
