Preheat the oven to 350 degrees. Line an 8x8 or 9x9inch baking pan with parchment paper (2 pieces to wrap up both sides), or foil to cover the sides, then nonstick spray. Set it aside.
Add the butter, brown sugar, and vanilla extract to a large mixing bowl and stir them together. 3/4 cup Unsalted Butter, 3/4 cup Brown Sugar, 1 TBS vanilla extract
Add in the flour, oats, baking soda and salt and stir it together until you have a nice soft cookie dough.1 cup all purpose flour, 1 cup Old Fashioned Oats, 1 tsp baking soda, 1/2 tsp salt
Press half of the oatmeal cookie mixture into the prepared pan. And set the other half aside.
Bake the bottom layer for 10 minutes, and remove it from the oven.
Add the cookie butter to a microwave safe bowl. Microwave for 30 seconds, stirring afterwards until its creamy and pourable. 1 cup Creamy Cookie Butter
Sprinkle the chocolate chips over the cooked crust. 1 cup chocolate chips
Pour the cookie butter evenly over the chocolate chips and crust.
Press pieces of the remaining oatmeal cookie dough between your hands to flatten, and place them around the top of the caramel, covering the caramel as much as you can.
Return the pan to the oven and bake the bars for another 14 to 16 minutes, or until the edges are lightly golden.
Remove the bars from the oven and let them cool completely, this may take 3 to 4 hours. If you want to speed up the cooling time, let the pan cool to touch, then add it to the fridge to chill for another hour or two.
