How to Make It
Preheat the oven to 350º. In a large mixing bowl or stand mixer, cream the peanut butter, butter, sugars and vanilla. Add eggs, one at a time, beating well after each addition. Set aside.
In a separate bowl, whisk together the flour, baking soda and salt and slowly mix into batter. Stir in the oats, chocolate chips and butterscotch chips.
Form the dough into roughly 1/4-cup balls and gently flatten each on a greased cookie sheet. Bake for 15 minutes, or until the edges are lightly browned. Remove from the oven and let the cookies cool for a few minutes before transferring to a wire rack to cool completely.
