4. Make a hole in the centre of the dry ingredients and pour in the mixture of the liquid ingredients.
5. Use a metal spoon and mix together to make the batter.
6. Remove the First Choice Custard cubes from the freezer and remove them from the tray – keep aside.
7. Spoon one large tablespoon of batter into each muffin hole.
8. Add a frozen First Choice Custard cube to each muffin hole.
9. Add another large spoon of cake batter to each muffin hole, covering the custard cube.
10. Bake for about 16-18 minutes until the lava cakes are cooked and golden brown.
11. Allow cooling for at ±15 minutes before removing the cakes from the muffin pan, taking care not to break the cakes.
12. Serve with scoops of ice-cream and garnish with lemon slices. Dust with icing sugar.
