Preheat oven to 350 degrees. In a large bowl, mix together the flour, ginger, baking powder, and baking soda. In a separate bowl, combine the eggs, carrot, zucchini, brown sugar, coconut, walnuts, oil, honey, and vanilla.
Add wet ingredients to flour mixture and stir until fully combined. Grease a 13x9 inch baking dish lined with parchment paper and pour batter in, making sure it is level.
For the Cream Cheese Frosting, whisk together the ingredients into a creamy consistency.
Bake for 30-35 minutes or until a toothpick comes out clean. Once cooked, place in refrigerator until completely cooled, cover with Citrus-Cream Cheese Frosting and sprinkle over some cinnamon.
Notes
Make sure that it is completely cooled before you add the frosting, otherwise it will melt.
