Use a grater to shred the zucchini. Let it sit for 10 minutes, then squeeze out the excess moisture.1 cup shredded zucchini
In a bowl whisk together the eggs, oil, milk, vanilla, cinnamon and brown sugar, until smooth. I like to use my hand blender to do this.3 large eggs, 1 1/2 cups milk, 1/4 cup oil, 1 tsp vanilla extract, 1 1/4 tsp ground cinnamon, 1/2 cup brown sugar
Stir in the shredded zucchini.
In a separate bowl, whisk together the oats, sugar, baking powder, and salt.3 cups quick oats, 2 tsp baking powder, 1/4 tsp salt
Combine the egg mixture and the oat mixture.
Pour into an 8 X 8 baking dish. At this point you can do 1 of 2 things: cover and refrigerate overnight then bake in the morning, or let it rest for 15 minutes and bake right away.
In the morning put the dish, uncovered, into a cold oven and bake at 350 degrees F for 40 – 45 minutes. If you are baking it the same day you make it, bake it at 350 degrees F for 40 minutes.
