• Step 1: Line a 9×13-inch baking pan with parchment paper, ensuring there’s an overhang on the sides for easy removal.
• Step 2: Distribute the crushed pretzels evenly across the bottom of the pan to form a solid base.
• Step 3: In a medium saucepan, heat the sweetened condensed milk, butter, and brown sugar over medium heat. Stir continuously until smooth and starting to bubble. Keep cooking for 3-5 minutes until slightly thickened.
• Step 4: Pour the caramel mixture over the crushed pretzels, using a spatula to spread it evenly.
• Step 5: Drizzle the melted chocolate over the caramel layer, smoothing it out with a spatula. Optionally, sprinkle sea salt flakes on top for added flavor.
• Step 6: Refrigerate the bars for at least 2 hours or until the chocolate is firm and the layers have set.
• Step 7: Lift the bars from the pan using the parchment paper. Cut into squares and serve.

Variations

• White Chocolate Version: Substitute the semi-sweet chocolate chips with white chocolate for a different taste.
• Nutty Add-in: Mix in chopped nuts like pecans or almonds into the caramel layer for extra crunch.
