Caster Sugar 200 g
Dark Brown Sugar 120 g
Vanilla Bean Paste 2 Teaspoon
Eggs 150 g

1. Start by bringing all the liquid ingredients, eggs and butter to room temperature.
2. Line two 18 cm cake rings/pans with parchment paper around the borders and the bottom.

4. Cream the mix until light and fluffy in texture.
5. Add in the eggs, one at a time until well incorporated before adding in the next egg.
6. Whisk to combine the yogurt, Lemon juice and milk together. In a separate bowl, sift all the dry ingredients together.
7. Once all the eggs have combined and the mix is smooth, alternatively, add in the yogurt/milk mix and the dry ingredients in 3 additions, starting with the liquid, ending with the dry mix.
8. When all the ingredients have come together, divide the cake mix in to two tins/rings (roughly around 670 g per ring/tin). Using a spoon or a small offset spatula, smooth out the top and tap the pans until they are even and to rid of any large gaps in the mix.
9. Bake in a preheated oven at 175°C for 45 - 50 minutes or until when tested with a skewer in the centre, it comes out clean.
Do not worry too much if the cake has a dome or crack at the top because you will be trimming them off later on.
10. Let the cake cool slightly, then remove from the tin/pan. Wrap the cake while still slightly warm and place in the fridge to cool fully. This will help keep the cake keep moist.
11. When the cakes are fully cooled, trim off the top then divide each cake in to 2 even slices horizontally with a serrated knife. You will have 4 portion in total.
