Line a 9x13-inch baking dish with parchment paper, leaving extra over the edges for easy removal. Spread the crushed pretzels evenly over the bottom of the pan.
Step 2: Make the Caramel Layer
In a saucepan over medium heat, melt the butter and brown sugar, stirring until combined. Add the sweetened condensed milk and bring to a gentle boil, stirring constantly to prevent burning. Allow the mixture to cook for about 5-7 minutes until thickened and caramel-colored.
Step 3: Pour Caramel Over Pretzels
Pour the caramel mixture evenly over the crushed pretzels, using a spatula to spread it out smoothly.
Step 4: Add the Chocolate Layer
Sprinkle the semi-sweet chocolate chips over the warm caramel layer. Allow them to sit for a few minutes to melt, then spread the chocolate evenly over the caramel.
Step 5: Optional White Chocolate Drizzle
If using, melt the white chocolate chips in a microwave-safe bowl in 30-second intervals until smooth. Drizzle the melted white chocolate over the chocolate layer for a decorative touch.
Step 6: Chill and Slice
Refrigerate the bars for at least 1 hour, or until firm. Once set, lift the bars out using the parchment paper and slice into squares. Serve and enjoy!
Notes
Melting the Chocolate: If the chocolate doesn’t spread easily, you can microwave it for a few seconds until smooth.
Extra Crunch: Add chopped peanuts or almonds to the pretzel layer for added crunch and flavor.
Avoid Sticky Bars: Ensure the caramel is fully set before cutting to avoid overly sticky bars.
