Preheat the oven to 275 degrees.
Line a baking sheet with parchment.
Spread the pretzels on the prepared baking sheet in a single layer. Try to space them out giving ½ “ to 1” between each pretzel to allow for the melting of the caramel.
Top each of the pretzels with a caramel square.
Bake for 10-15 minutes or until the caramels have softened but aren’t completely melted. They will expand a bit as they warm, but you don’t want a gooey mess with a tray full of liquid caramel.
Prepare the apples while the pretzels are baking. Chop and then soal in lemon juice or salt water to help to keep them from browning.
Drain the apples from the water and pat dry.
When the pretzels are done baking, remove and immediately add a piece of apple to the top of each melted caramel. Press into the caramel so that once the caramel cools it will hold the apple in place.
Melt the chocolate in a microwave-safe dish on 50% power in 30-second intervals, stirring inbetween each interval until smooth and glossy.
Transfer to a piping bag or decorating bottle fitting with a small round tip.
Drizzle melted chocolate over the top of the bites in any pattern you desire.
Immediately sprinkle with chopped peanuts while the chocolate is warm so that it will hold the peanuts once it sets.
Allow the bites to cool completely before serving.
