Greek Spiced Walnut Cake - 希腊肉桂核桃蛋糕

Yesterday was one of my colleague's last working day in the company. To bid farewell, he bought us a delicious hazelnut cream cake. The cake is light and moist with aroma of cinnamon. Everyone likes the cake, and some of my colleagues even said the cake reminded them of my walnut cake ! It's really a compliment to me. Actually, my walnut cake does not have cinnamon in it.
