Preheat the oven to 350 degrees and spray a large cookie sheet with cooking spray. Set aside.
In a medium-sized bowl, stir together the flour, baking soda, ground cinnamon, and salt. Set aside.
In a 2-quart mixing bowl, stir tougher the oil, granulated sugar, and brown sugar. Next, stir in the eggs and vanilla. Mix well until eggs are completely incorporated.
Add the flour mixture and stir until just combined. Next, add the grated zucchini and mix well, making sure there are no clumps of zucchini.
Bake at 350 degrees for 20-25 minutes or until a toothpick inserted in the center comes out clean.
Let cool completely before frosting. I like to cool it in the fridge or freezer to lock in more moisture. Once it is completely cooled, mix up the frosting.
FROSTING:
In a medium-sized bowl using a hand mixer, mix the cream cheese and butter together until they are completely incorporated.
Next, add the powdered sugar, vanilla, and 2 tbsp of milk. Mix until nice and creamy. Add more milk if you feel it is too thick.
Frost the cake and ENJOY!
