Preheat the oven to 350°F and grease a 9x13-inch baking pan with cooking spray.
In a medium bowl, combine the softened butter, brown sugar, flour, oats, baking soda, and salt. Beat with an electric hand mixer until well mixed.
Press three-quarters of the dough evenly into the bottom of the prepared pan to form a thin crust layer.
Bake the crust for about 15 minutes or until lightly browned. Avoid overbaking.
While the crust bakes, melt the remaining butter, heavy cream, and unwrapped caramels over very low heat, stirring constantly until smooth.
Pour the melted caramel mixture over the warm baked crust.
Sprinkle milk chocolate chips evenly over the caramel layer.
Crumble the remaining cookie dough evenly over the chocolate and caramel layers.
Return the pan to the oven and bake for another 15 minutes.
Remove from oven and cool completely before cutting into bars.
Serve and enjoy your decadent Binge Bars.
