This recipe for Oatmeal Chocolate Chip Cookies has been around for years and is a proven winner. The thing is, while cookie recipes like Peanut Butter Oatmeal and Jam Thumbprints are so, so good, I’m a big fan of cookie bars.

I love the fact 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.
- Prepare the pan by lightly greasing a 9 x 13-inch baking dish with cooking spray or line it with parchment paper.
- Allow the bars to cool completely in the pan resting on a wire rack, before slicing. This will help them hold their shape and prevent them from falling apart.
Often Asked Questions And Answers
Yes, but the texture may be slightly different.
Line the pan with parchment paper or coat it with non-stick cooking spray.
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!
