Begin by microwaving 1¾ cups of milk chocolate chips in a large, microwave-safe bowl. Heat the chocolate in 15-second intervals, stirring vigorously between each interval until fully melted and smooth, which should take about 1-2 minutes total.

Once the chocolate is melted, pour it onto a sheet of parchment paper laid out on a baking tray. Using a spatula, spread the chocolate into a rectangle shape, about ¼ inch thick.

Press pretzels firmly into the melted chocolate, covering the surface evenly. Ensure the pretzels are partially submerged in the chocolate.

Dice a green apple into small, bite-sized pieces and pat the diced apples dry with a paper towel.

In a separate microwave-safe bowl, combine 35 individually wrapped caramels or 13.5 ounces of caramel dip. Microwave the caramels in 15-second intervals, stirring well until completely melted and creamy.

Spread the caramel-apple mixture evenly over the pretzel layer and chill for about 30 minutes. Melt additional milk chocolate chips to drizzle over the top and chill again for an hour.

Remove your Caramel Apple Bark from the refrigerator and use a sharp knife to cut it into bite-sized pieces.
