Step 1

Preheat oven to 350 degrees. Grease a 9x13'' baking pan.

Step 2

Add oil, granulated and brown sugars to a mixing bowl and beat well to combine. Add pineapple, eggs, vanilla and sour cream. Stir in grated zucchini.

Step 3

In a separate mixing bowl whisk together flour, baking powder, baking soda, salt, cinnamon, nutmeg and ginger. Add to the wet mixture, stirring just until combined.

Step 4

Pour batter into prepared pan and bake for 30 - 35 minutes or until a toothpick inserted into center comes out clean. Allow to cool completely before frosting.

Step 5

Add the cream cheese and butter to a mixing bowl and cream together until pale and fluffy. Add powdered sugar and vanilla and whip until fluffy, about 3-4 more minutes.

Step 6

Spread frosting over cooled cake. Sprinkle a little bit of cinnamon sugar on top, if desired.
