- Start beating at lowest speed setting until ingredients come together. Increase the speed to maximum and beat until the batter is completely smooth - about 30 seconds to one minute. Stop the mixer and scrape the bottom and sides of the bowl halfway through.
- Transfer batter to the prepared cake tin and level using a spatula.
- Bake for 30-35 minutes or until the cake is golden and feels springy to the touch. A skewer or knife inserted in the centre should come out clean – if not cook for a further 5 minutes.
- Lift the cake out of the tin using the overhanging paper and transfer to a wire rack to cool.
Make the Biscoff Buttercream

Notes
- If you are using self raising flour then add only 1 tsp baking powder (no baking soda).
- Unless specified otherwise all your ingredients including butter eggs and milk should be at room temperature in order to achieve a smooth batter. If one or more of the ingredients are cold they will cause your batter to split or look curdled.
- If your milk is cold from the fridge then heat briefly in the microwave or saucepan until just tepid. Make sure the milk is body temperature - not too hot!
- Place cold eggs into warm water for five minutes to bring them back to room temperature.
- Cut cold butter into cubes and leave for an hour on your counter to warm up or use margarine (Stork).
- This is a great cake for bake sales and parties as it serves a big crowd. It keeps well in an airtight container for 2-3 days if you want to keep it all to yourself!
