Step-by-Step Instructions
We start by prepping our pan. I line my 9×13 inch pan with foil or parchment paper and give it a generous coat of cooking spray. This isn’t just for easy cleanup—it’s essential for getting these rich bars out in one piece later. Then, I take my pretzels. I’ve found the best method is to put them in a zip-top bag and use a rolling pin to crush them. You’re aiming for about 1 ½ cups of crumbs and the rest in small pieces. Dump this into the prepared pan and press it into a fairly even layer. Don’t worry about perfection here, just get it settled.
Now, for the glorious, gooey filling. In a medium saucepan over medium heat, I melt the butter. Once it’s fully melted and just starting to foam, I whisk in the packed brown sugar. This is where the kitchen starts to smell amazing. I whisk it constantly for a full minute until it’s smooth and bubbly. Then, I pour in the entire can of sweetened condensed milk and the vanilla. Here’s a key moment: keep whisking! I let it come to a gentle bubble and then cook, whisking non-stop, for exactly 3-4 minutes until it thickens slightly and turns a beautiful caramel color. I learned the hard way that walking away can lead to scorching on the bottom.
Immediately, I pour this hot, heavenly caramel mixture over the pretzel layer. Working quickly with a spatula, I spread it as evenly as I can. The pretzels will float and shift a little, and that’s okay. Now, walk away. Seriously, let this layer cool and set for at least 30 minutes. I was too eager the first time and melted my chocolate into a hot mess. This cooling time is non-negotiable for clean layers.(See the next page below to continue…)
