Prepare a large cookie sheet (13” x 18”) by lining it with parchment paper.
Melt 2 cups of chocolate chips in the microwave. (Set aside the remaining ½ cup aside for drizzling later.) Start with 30 seconds on high power, stir well. Then cook for 15 seconds at a time on high power. Only cook them until you can stir the chocolate chips smoothly.
Spread onto the prepared cookie sheet.
Place the pretzels in one even layer all over the top of the chocolate.
Unwrap and melt the caramels in the microwave. Again, start with 30 seconds on high power then stir well. Continue cooking for 15 second intervals stirring well in between. Cook this until it gets bubbly.
Dice the apples, then pat them with paper towels to remove excess moisture.
Mix the diced apples into the melted caramel.
Pour this mixture evenly over the base, then carefully spread. Place the pan into the refrigerator and allow it to cool for half an hour.
Melt the remaining ½ cup of chocolate chips and drizzle it over the bark.
Return the bark to the refrigerator until completely set. (This may take a few hours.) Remove it from the refrigerator and cut it up into pieces.
Notes
You can use any type of apple you'd like.
I did not peel the apples but you can if that is your preference.
Use milk, semi-sweet or dark chocolate.
Caramel sauce can be used but it has to be thick.
You can use regular square caramels instead of bits.
