Melt butter in small saucepan until it begins to clarify. The fat solids will fall to the bottom and begin to brown; scrape them from the bottom of the pan and remove from burner. Liquid should be caramel in color.
In standing mixer, beat browned butter and sugars together for about 3 minutes.
Mix in the vanilla along with the eggs.
In a separate bowl whisk together the flour, baking soda, baking powder and sea salt. Blend into butter/sugar mixture just until incorporated.
Stir in caramel bits, broken pretzels, chocolate chips and toasted pecans until equally distributed.
Preheat your oven to 350°F.
Using a cookie scoop, drop them 2" apart on a parchment paper lined baking sheet.
