Preheat the oven to 350 degrees Fahrenheit. Prepare a 13x9 baking dish with parchment paper. Set aside.

In a large mixing bowl, cream together the brown sugar, granulated sugar, and butter with a hand mixer for about 2 minutes.

Add the eggs one at a time, mixing thoroughly before adding the next one. Add vanilla extract and baking powder. Add the flour gradually while continuously mixing. Mix until all the flour is mixed into the dough.

Mix in the chocolate chips with a spatula or wooden spoon. 

Take about 2/3 of the dough and press it down into the baking dish. Evenly cover the bottom of the dish with dough. Save 1/3 of the dough to top it off after you add the caramel mixture.

Add the caramel sauce and sweetened condensed milk to a saucepan over the stove. You want to warm it up just enough to allow both of the ingredients to mix together well. Pour the caramel evenly over the pressed-down dough. 

Using the rest of the dough, drop small pieces of dough on top of the caramel until it's evenly disbursed in the pan. The dough will cook and spread out, while still allowing caramel to peek through.

Place in the oven on the middle rack for 38-44 minutes. You'll know the bars are done when they are golden brown on top and the bars are fully cooked.  Allow to cool completely before cutting the bars into squares. Enjoy!
