- Place 8 biscuits on top of each cake, press them gently into the cake batter, so that they are semi submerged but still visible.
- Bake for 40 minutes on the middle shelf of the pre heated oven.
- To see if the cake is cooked, insert a skewer and if it comes out clean the cake is ready, there should also be a spring to thecae we touched gently.
