Preparation

Step 1

Preheat oven to 350 degrees. Spray a bar pan (10 x 15) liberally with cooking spray.*
In the bowl of a stand mixer fitted with the paddle attachment, cream together the butter and brown sugar until fully incorporated and creamy. Add in sweetened condensed milk & peanut butter. Mix together until fully incorporated. With the mixer on low, add in flour, baking soda & salt until combined. Add in oats and mix until combined. Add in chocolate chips and stir until evenly distributed.
Pour batter into prepared pan (if using 9 x 13 pan reserve 1 cup of the dough for cookies). Spread dough evenly. Bake for approximately 30 minutes until lightly golden brown and set in the middle. Remove pan from oven and place pan on a cooling rack. Let cool completely in the pan, then cut into bars and store in an airtight container.

* You can use a 9 x 13 pan but you will need to remove about one cup of the dough and set it aside so that the bars cook more evenly-I did this and my bars were still a little underdone in the center but done on the edges. I made some individual cookies with the extra dough and baked them for 8 to 10 minutes. Even though my bars were a tad underdone they set up as they cooled and made the bars have a great texture and since there’s no egg there is no worries about them possibly being underdone.
