Preheat oven to 375 degrees Fahrenheit. Spray an 8x8 baking dish with avocado oil or vegetable oil spray and set aside.

Blend oats in a high-speed blender so that turn into an oat flour.

In a large bowl, combine oat flour, baking powder, salt, cinnamon, shredded coconut (if using), chia seeds/basil seeds, ground flaxseed, and protein powder.

In a medium bowl, combine peanut butter, maple syrup, eggs, and almond milk.

Pour wet ingredients into the flour mixture and mix until fully combined.

Transfer breakfast bar dough into the baking dish and spread out evenly using a rubber spatula or a spoon.
