Step-by-Step Instructions
My first step is always to prep the pan, because once the caramel is ready, everything moves fast. I line my 9×13 inch baking pan with parchment paper, leaving an overhang on two sides to create a sling for easy removal. I give the parchment a light spritz of cooking spray—this ensures the bars will release perfectly. Then, I measure out my pretzels. I place them in a large zip-top bag and use a rolling pin to crush them. I aim for a mix of textures: some crumbs, some small pieces, and a few larger chunks for that signature pretzel bite.
Now, for the magic: the caramel. In my medium saucepan, I combine the butter and brown sugar over medium heat. I stir constantly with my heatproof spatula until the butter melts and the mixture comes to a boil. The moment it reaches a full, rolling boil, I set a timer for exactly 1 minute (90 seconds if you’re at high altitude). I stir continuously during this boil. This is non-negotiable—it cooks the flour out of the butter and allows the sugar to properly caramelize without burning. The smell is rich, buttery, and absolutely heavenly.
As soon as the timer goes off, I immediately remove the pan from the heat. I quickly pour the hot caramel over the crushed pretzels in my large mixing bowl. Working fast with my spatula, I fold and stir until every single pretzel piece is thoroughly coated in the glossy, amber-colored caramel. It will be thick and sticky, and you’ll hear a wonderful sizzle as you mix.(See the next page below to continue…)
