Butter a 8x8 baking pan and set aside.
In a large mixing bowl, beat the butter with an electric mixer until fluffy. Slowly add the sugar, continuing to beat.
In a saucepan, combine sugar, water, vanilla, cinnamon, juice, rind, and cloves.
Bring to a boil and simmer for around 30 minutes, or until slightly thickened. Strain syrup into small bowl.
Once cake is done, cut into desired pieces, and ladle hot syrup over hot cake. (Keep cake in pan)
Cover and let cool before serving.
Place cake on a dessert plate, add blood orange syrup, and serve.
