How to Make It: Step-by-Step
The secret to perfect pretzel bars is pressing the base firmly into the pan. If the pretzel crust is packed too loosely, the bars will crumble when sliced.
1- Build the Pretzel Base
Preheat your oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper, leaving a slight overhang for easy removal later. In a medium bowl, toss the 3 cups of crushed pretzels with the ½ cup of melted butter until the crumbs are thoroughly coated. Dump the mixture into your pan and press it down into a firm, even layer using the bottom of a flat measuring cup.
Place the pretzel crust into the preheated oven and bake for 10 minutes. This quick bake helps set the butter and pretzels so they hold their shape against the heavy toppings. Once done, remove the pan from the oven and set it aside.
3- Melt and Pour the Caramel
While the crust bakes, place the 11 ounces of unwrapped caramels and 2 tablespoons of heavy cream in a microwave-safe bowl. Microwave in 30-second bursts, stirring vigorously between each interval, until the caramel is completely smooth and melted. Pour the hot caramel evenly over the warm pretzel crust, smoothing it out with a spatula.
4- Layer Chocolate and Set
Immediately sprinkle the 1 ½ cups of chocolate chips over the hot caramel layer. Let the pan sit undisturbed for 3 to 5 minutes so the residual heat softens the chocolate. Once shiny and melted, use the back of a spoon to spread the chocolate into a smooth, glossy top layer. Bake the assembled bars for an additional 5 minutes to fully set the layers, then transfer the pan to the refrigerator for at least 1 hour to chill completely before slicing into squares.
Pro Tip: To make slicing an absolute breeze, run a sharp chef's knife under hot water, wipe it dry, and cut through the chilled bars. The warm blade will glide effortlessly through the chocolate and sticky caramel without tearing the layers apart!
