On a baking sheet, add as many graham crackers as you plan to use. Then, layer on the chocolate and marshmallow.
Broil for 1-2 minutes. This will broil fast! So keep a close eye.
Once the tops of the marshmallows are toasty, remove from the oven and add a graham cracker on top.
Air Fryer Method
Add a small piece of parchment paper (optional). Then, add one to two graham crackers, or as many as you have space for in your air fryer basket. Then, add the marshmallow.
Air fry at 390°F for 3-4 minutes. Once the marshmallow looks toasted, turn the air fryer off.
Add the chocolate on top of the toasted marshmallow and place the basket back in the (off) air fryer for 10+ seconds to melt the chocolate slightly.
Add the final graham cracker on top.
On a microwave-safe plate, add as many graham crackers as you want to make. Then layer on chocolate and marshmallow.
Microwave for 10-15 seconds. The marshmallow will puff up, but not necessarily turn gold-brown or toasted looking like the other methods.
Add the top graham cracker and enjoy.
Oven method - Do not use parchment paper under a broiler.Microwave method - Do not use Stuffed Puff marshmallows as I found the centers tended to ooze out or burn in the microwave method. Regular, unstuffed marshmallows are best.
