Caramel Oatmeal Cookie Bars, also known as Mountain Bars are thick, chewy bars filled with chocolate chips, oatmeal and caramel with an irresistible crunchy topping.

We were first introduced to these bars when we dined at local favorite, Ingredient in Kansas City. Chris couldn’t resist their Caramel Oatmeal Cookie Bars.

I recreated this magical treat, also known as Mountain Bars or Carmelita Bars. No matter what you call it, they’re amazing. Fortunately they’re incredibly quick and easy to make, too!

They’re made with a thick oatmeal cookie base, topped with a layer of chocolate and creamy caramel and crumbly topping that browns to perfection. The result is a decadent, easy-to-serve dessert that you can take to tailgates and bonfires or serve hot and a la mode for an evening entertaining at home!

I love cookie bars like Sugar Cookie Bars and Chocolate Chip Salted Caramel Cookie Bars because they’re quicker and easier than having to make individual cookies. Not to mention, every bite is like the deliciously chewy center! Instead of dropping dough onto cookie sheet after cookie sheet and spending your afternoon baking, you just drop it all into a 9×9 baking dish and slice!

  • Butter – Salted or unsalted.
  • Brown Sugar – Adds great caramelized flavor and sweetens the bars.
  • Flour – All purpose flour makes the cookie base and crumb topping.
  • Oats – Rolled oats for added texture.
  • Baking Soda – The leavening agent.
