1. Make the Pretzel Crust:

• In a medium mixing bowl, stir together the crushed pretzels, melted butter, and 1/2 cup of peanut butter until the mixture resembles wet sand.
• Press it firmly and evenly into the bottom of a parchment-lined 9×9-inch baking pan to form your crust. Pop it in the fridge while you work on the next layer.

2. Make the Peanut Butter Layer:

• In another bowl, blend the remaining 1/2 cup of peanut butter with the powdered sugar until smooth and thick.
• Spread this mixture evenly over the chilled pretzel crust. Use the back of a spoon or an offset spatula to smooth it out.

3. Make the Caramel Layer:

• Combine the caramel candies and heavy cream in a microwave-safe bowl. Heat in 15-second bursts, stirring each time, until the caramel is melted and silky.
• Pour this warm caramel over the peanut butter layer and gently spread it to the edges.

4. Top with Chocolate:

• Melt the chocolate chips in the microwave (30-second intervals, stirring in between) or over a double boiler until completely smooth.
• Pour the melted chocolate over the caramel and spread it evenly with a spatula.

5. Chill and Slice:

Place the pan in the fridge for at least 1–2 hours, or until the bars are fully set. Once firm, lift them out of the pan using the parchment paper and slice into squares or bars.
