In a small glass bowl, pour the Hershey’s milk chocolate chips, reserving about ¼ cup for later use. Microwave the bowl in 20-second intervals until the chocolate is fully melted and smooth.
Line a baking sheet with parchment paper and spread the melted chocolate evenly onto the parchment paper.
Arrange the mini twist pretzels on top of the melted chocolate, allowing them to overlap slightly to form a single layer.
In another microwave-safe bowl, combine the Kraft caramel bits with 2 tablespoons of water. Microwave the caramel mixture for 1 ½ to 2 minutes, or until fully melted and smooth. Stir occasionally to ensure even melting.
Drizzle the melted caramel over the layer of pretzels, spreading it out evenly with a spatula. Allow the caramel layer to cool slightly.
Microwave the reserved ¼ cup of Hershey’s milk chocolate chips until melted, then drizzle the melted chocolate over the cooled caramel layer.
Repeat the process with the Reese’s peanut butter chips, melting them and drizzling them over the bars.
Let the bars cool completely at room temperature or in the refrigerator until the chocolate and caramel are set.
Once cooled and set, cut the bars into squares or rectangles.
Serve and enjoy these irresistible No-Bake Caramel Pretzel Crack Bars as a sweet and salty treat!
