Preheat your oven to 300 degrees and line a baking sheet with parchment paper or a silicone baking mat.
Place half of the Ritz crackers upside down on your prepared baking sheet, then top each cracker with a Rolo.
Bake for 4 minutes to soften the Rolos, then sandwich another Ritz cracker on top, pressing down slightly to flatten the Rolos, then place in the freezer to allow the Rolos to set.
In the meantime, lower your oven temperature to 200 degrees F and spread a thin, even layer of nonpareils sprinkles onto a baking sheet.
Place the Hershey's Kisses on top of the sprinkles, evenly spaced apart and bake for 10 minutes to fully soften the kisses.
Remove the tray from the oven and gently press a Rolo stuffed Ritz cracker onto each softened kiss.
Return to the fridge or freezer for 15 minutes or until the chocolate is firm.
