In a microwave safe mixing bowl, melt chocolate chips and coconut oil until smooth. (around 90 seconds for me) Be careful not to burn. Check every 30 seconds to stir.

Once the coconut oil and chocolate are melted, add in the olive oil, vanilla extract, sugar, and brown sugar.

Use a whisk to combine well

Whisk in 3 eggs one at a time until combined

In a separate bowl, whisk together the dry ingredients: oat flour, coconut flour, cocoa powder, baking soda, and salt

Add the dry ingredients to the wet, and use a rubber spatula to mix until just combined (do not over mix)

Line an 8 X 8 baking dish with parchment paper

Pour in the batter and spread out evenly

Bake at 350 degrees for 28 - 33 minutes, until the center is cooked and no longer jiggly

Allow to cool 10 minutes in pan

Lift the edges of the parchment paper to remove the brownies from the pan

Allow to cool before cutting, to avoid crumbling
