Preheat the oven to 200°F and line a large baking sheet with paper.
Unwrap the Hershey's Kisses, setting them aside for easy access. You’ll need one for each pretzel.
Lay out a single layer of pretzels on the prepared baking sheet, using the desired amount of treats you prefer, or however many kisses you have.
Place a Hershey's Kiss onto the center of each pretzel.
Bake at 200°F for about 4-5 minutes. Keep an eye on them: the Hershey Kisses should become glossy and soft, but they should not fully melt into puddles. The goal is to soften the chocolate just enough for the next step.
Remove the baking sheet from the oven and immediately press an M&M candy into the center of each softened Hershey’s Kiss. The M&M will gently sink into the chocolate, and allow the chocolate to sink into the pretzel, helping it stick to the pretzel when the chocolate is hard.
Place the baking sheet in the fridge for about 15-20 minutes, or until the chocolate has fully set and hardened.
Once chilled, remove the Hershey's Kiss Pretzels from the fridge. Serve them up at your next gathering or enjoy them as a sweet snack to satisfy your cravings!
