Prepare the flax egg: In a small bowl, combine 1 Tbsp. flax seed meal and 3 Tbsp. water. Place in the refrigerator to firm up for about 15 minutes.
Preheat oven to 350 degrees and grease a 13 x 9-inch baking dish with cooking spray.
In a large bowl, combine all dry ingredients: oats, flour, coconut, chocolate chips, and salt. Mix in coconut extract, vanilla, honey, almond milk, vegetable oil, and flax egg. Spread in prepared pan, pressing down firmly to smooth.
Bake about 30 minutes. Let cool 10 minutes, then slice into 16 bars. Store covered at room temperature.
