Roll out the crescent dough and cut into 6 squares.
Place a couple of squares of chocolate and a tablespoon of graham cracker crumbs in the center of each square.
Brush the egg wash (or use your finger) along the edges of the square and fold the square over diagonally (the top left corner pulled down to the bottom right corner, so it forms a triangle). Press the edges together, you can use a fork to decorate the edges if desired.
Brush the s’mores with more egg wash and sprinkle with sugar if desired.
Place in the air fry toaster oven on the air fry basket and slide into the oven. Turn the dial to air fry and set the time to 6 minutes. Bake until the s’mores are golden brown.
Once done, let cool for a few minutes and then heat up the marshmallow fluff and drizzle over the s’more. You could also use the marshmallow fluff as a dipping sauce for the s’mores.
