Preheat the oven to 350 degrees F.
Line two baking sheets with parchment paper.
In a large bowl, whisk together melted coconut oil, brown sugar, and granulated sugar until well combined.
Add the egg, egg yolk, and vanilla extract, mixing until combined.
Add the flour, oats, brewers yeast, flaxseed meal, baking soda, and salt, and mix well until combined.
Fold in shredded coconut and chocolate chips.
Let the dough sit for 10 minutes.
Scoop dough balls with a cookie scoop and place on prepared baking sheets, about 6 per baking sheet.
Bake in the preheated oven for 9-10 minutes, until the edges are golden brown. Don't over bake! They will set up more after cooling.
Cool completely, and enjoy!
