In the bowl of an electric mixer, cream together coconut oil, softened butter, and sugars on medium speed. Add eggs one at a time, then vanilla extract, mixing in between.
In a separate bowl, mix flour, baking soda, salt and oats. Gradually add to the wet ingredients on low speed until a dough forms.
Stir in chocolate chips and mix until incorporated into the dough.
Roll the dough into 1 1/2 inch balls, and place them on a Silpat or parchment lined baking sheet.
Bake at 350 times 8-10 minutes, then cool on a cooling rack.
