preheat oven to 170℉

place pretzels on a baking tray, do not double layer them

place Hershey kisses in center of pretzels

place baking sheet(s) in oven for 5-8 minutes for desired meltiness of kisses

after they have been pulled from oven, place M&M's on top of kisses (if pulled at 5 minute mark, kisses will still be firm except for 1/4in of the tip)

let set and harden ship the M&M's stay in place, you can chill them if you want to, put on plate or tray and serve.
