• The cake can also be made in an oven by cooking it on Fan Plus at 160°C for 50 minutes or until golden and cooked through.

• If you can’t source buttermilk, you can quickly make your own at home by mixing together 1 tbsp of lemon juice through 1 cup of milk and allowing it to sit for at least 10 minutes.
• If you don’t have a tube pan, a 26cm cake tin will give the same fantastic result.
