Preheat the oven to 325 F.

Line a 9x13” baking pan with foil and then spray with nonstick cooking spray. Add a layer of broken pretzels evenly over the bottom of the pan. Be sure that the extra salt crumbs from the bottom of the bag don’t fall in the pan, or your brownies will end up being too salty!

In a pot, set over medium low heat, melt the chocolate chips along with the butter. Off the heat, whisk in the sugars. Let the mixture cool slightly.

Whisk in the eggs, one at a time, and add in the vanilla. Stir in the flour and salt. Mix well.

Spread the batter carefully into the pan, making sure that the pretzels remain in an even layer. Bake for 45 minutes, or until a toothpick inserted into the batter comes out clean. Cool and cut into bars.
