Preheat oven to 350 degrees. Line a cookie sheet with parchment paper or lightly grease. Set aside.
In a large bowl or stand mixer, cream butter, brown sugar, white granulated sugar, and peanut butter until smooth and fluffy- around 2 minutes. Stir in eggs and vanilla extract until combined.
In a separate bowl, combine flour, baking soda, salt, and oats. Add dry ingredients to peanut butter mixture and mix until just combined. Stir in chocolate chips. Scoop dough into heaping tablespoon size ball and place on baking sheet.
Bake for 10-12 minutes or until the edges are just slightly browned and the top appears baked through. Remove cookies from cookie sheet and allow to cool. Enjoy!
