Preheat your oven to 350°F (175°C). Line a 9x13 inch pan with parchment paper.
In a bowl, mix flour, brown sugar, and melted butter until crumbly. Press this into the bottom of your prepared pan.
Bake the crust for 10 minutes until just set. It’ll smell amazing already.
Sprinkle the pecans and chocolate chips evenly over the warm crust.
Drizzle the sweetened condensed milk over the top—don’t worry about perfection here, just let it rain.
Bake for another 25 minutes or until the edges start to brown and the center looks just barely set.
As soon as it’s out of the oven, drizzle caramel sauce all over the top.
Cool completely in the pan before cutting into bars. If you can wait that long, you’re stronger than I am.
