The most delicious and gooey chewy oatmeal chocolate chip cookie bars that are quick and easy to mix up. So much easier than individual cookies and easy to serve to a crowd.
Line a 9x9 pan with parchment paper and set aside. Preheat your oven to 350℉.
In the bowl of a stand mixer or large mixing bowl, add your butter and sugars. Beat them together on medium speed for 3-4 minutes until creamed together.
Add in your egg and mix in on low speed. Then mix in the vanilla extract on low speed.
Then add in the flour, oats, baking soda, baking powder and salt. Mix on low speed until fully combined. Then add the chocolate chips and mix on low speed until combined.
Dump the dough into your prepared pan and with wet fingers, push the down into all the corners so it's spread evenly in your pan. Bake for 19-21 minutes or until the top has started to turn golden brown. Don't overbake to keep the cookies soft.
Allow to cool for at least 10 minutes before slicing into squares. Let them fully cool before storing leftovers in an airtight container and enjoy!
