Preheat the oven to 350℉. Line baking sheets* with parchment paper and set aside.
In a large bowl, mix together the oats, flour, sugars, baking soda and salt. Add in the oil, eggs and vanilla, and mix until fully combined.
Fold in the chocolate chips and butterscotch chips.
Using a medium cookie scoop, scoop the cookie dough onto the prepared baking sheets and bake in the preheated oven for 10-12 minutes, or until set and golden.
Notes
This recipe makes a lot of cookies, so you will need to make them in quite a few batches.
