Note: I didn't have 9" pans so used 8" ones. It worked, but I cooked it a lot longer and it was still undercooked.
Two 9" round spring-form pans, greased and lined with baking parchment
160°C | 315°F
70-75 minutes (or until a toothpick comes out clean)
Share mixture between both tins. Tap on counter to settle mixture.
Bake until toothpick comes out clean.
Leave to cool in the tins completely before removing.
Cut each cake in half so you have 4 layers.
Spread 3 spoonfuls of icing between each layer.
Spread the remaining icing on the top and sides.
