Set your oven to 275°F and line a baking tray with parchment paper for easy cleanup.
Lay your pretzel snaps on the tray, making sure they’re spaced out. Place a caramel square on top of each pretzel.
Slide that tray into the oven for about 10-15 minutes, just until the caramel softens. Be careful not to over-bake! You want the caramel to be gooey and soft, not a total melty mess.
While the caramel is doing its thing in the oven, core and cube your granny smith apples into 1-inch pieces. To keep them from turning brown, soak the apple cubes in lemon juice or salt water for a few minutes, then pat them dry.
When the pretzels and caramel come out of the oven, quickly press an apple cube onto each caramel pretzel. This will help the apple stick to the warm caramel.
Melt your chocolate chips or wafers in a microwave-safe piping bag, using the defrost or low setting to prevent burning. Once melted and smooth, snip the tip of the bag and drizzle the chocolate over the caramel pretzel bites.
Sprinkle chopped peanuts (or your choice of nuts) over the drizzled chocolate before it sets.
Allow the bites to cool completely so everything can set, and you’re ready to dig in!
