Simple Spice Cake With a Hint of Grapefruit
This cake is good when you don't want to make something too sweet with cream and icing and stuff. The sweetness comes from just cinnamon, sugar, and a little grapefruit. Use grapefruit slices for garnish. You can use honey with grapefruit zest instead of the powdered sugar and water if you don't like sugary glazes.
