These oven s'mores are gooey, toasty, and ready in just minutes with no campfire needed. Made with a Reese's peanut butter cup instead of a plain chocolate bar, they're the easiest way to enjoy a classic s'more any time of year.
Place half of 8 graham crackers on a baking sheet lined with aluminum foil for easier cleanup. Place one large marshmallow on top of each.
Turn the oven on a low broil and broil the s’mores for about 3-4 minutes, watching the whole time to ensure the marshmallows do not burn, or fall off the crackers.
Once the marshmallows have broiled and are golden, remove from the oven. Add a Reese's peanut butter cup on top of the marshmallow, then place the other half of the graham cracker on top of the peanut butter cup. Press down slightly, and enjoy!
