Preheat oven to 350 degrees f.
Spray your 8x8 brownie pan with nonstick spray, or wipe your pan with coconut oil.
Pulse oats in blender or food processor until finely ground. (dry oats are measured BEFORE grinding...always get lots of questions about this)
In a separate bowl, sift or whisk dry ingredients together; cacao powder, ground oats, baking soda, and sea salt; until well combined.
Using your mixer, cream peanut butter, applesauce, egg, maple syrup and vanilla until smooth.
Add shredded zucchini, mix until combined.
Add dry ingredients into wet, mix just until combined...do not over mix.
Stir in half of the chocolate chips.
Pour batter into your prepared baking pan and sprinkle remaining chips on top.
Bake for 23-26 minutes in your preheated oven.
Cool before slicing into squares.
