In a small saucepan, bring the sugar and water to a boil. Simmer for approximately 5 minutes or until you've reached your desired syrup consistency. Add the remaining ingredients and stir until combined. Take the syrup off the heat and set aside.

Poke 10 to 15 holes into the bottom of the cake with a toothpick when the cake is just out of the oven. Once the syrup has cooled, brush the syrup onto the bottom of the warm cake. The syrup will soak into the cake while it's cooling and add lots of moisture and flavour.
