This recipe for Oatmeal Chocolate Chip Cookies has been around for years and is a proven winner.  The thing is, I don’t really like to make cookies (I know, it’s awful), which means my twist on this recipe is right up my alley.

I guess it was just that impatient part of my soul showing out, when I decided to make the recipe into cookie bars.  It worked beautifully. I love that I can cut them into any size and customize the flavors. I often add raisins for my one guy and coconut for the other, and then there’s Mr. SS, who will eat them any ‘ol way.

Successful Tips For Making Oatmeal Cookie Bars

Here are a few tips that can help ensure your oatmeal chocolate chip cookie bars turn out perfectly:

  • Make sure your butter is at room temperature before beginning the recipe. Softened butter will mix more easily with the other ingredients, resulting in a smoother dough.
  • Don’t over-mix. Over-mixing the dough can result in tough bars. Mix the dry ingredients with the wet until just combined for the best texture.
  • Allow the bars to cool completely in the pan before slicing. This will help them hold their shape and prevent them from falling apart.

Often Asked Questions And Answers

Can I use quick oats instead of old-fashioned oats?

Yes, but the texture may be slightly different.

How can I keep the bars from sticking to the pan?

Line the pan with parchment paper or coat it with non-stick cooking spray.

How To Store Leftovers

Store the bars in an airtight container at room temperature for 3-4 days. You can freeze the bars for up to 3 months and thaw them at room temperature before serving.

Ways To Serve Oatmeal Chocolate Chip Cookie Bars

  • Warm: Heat a bar in the microwave for 10–15 seconds, then add a scoop of vanilla ice cream. The warm cookie bar and sweet ice cream are a match made in heaven!
  • With Coffee: Enjoy a bar with a hot cup of coffee or tea for a cozy afternoon snack.
  • Lunchbox: Pack a bar in your or your kiddo’s lunchbox for a sweet, healthy dessert.
  • On-the-go: Take a bar with you as you head out the door on a busy morning.
