Step 1: Prepare your workstation. Lay out your four large flour tortillas. If using large marshmallows, have them ready. If using mini marshmallows, measure out 2 cups. Melt your chocolate chips, chocolate bars, or prepare your hazelnut spread.
Step 2: Spread chocolate. On each tortilla, spread about a quarter cup of chocolate spread, leaving a 1-inch border around the edge.
Step 3: Add marshmallows. Distribute 3-4 large marshmallows or about half a cup of mini marshmallows evenly over the chocolate on each tortilla.
Step 4: Fold the crunchwrap. Starting from one side, fold the edge of the tortilla inwards over the filling, creating a small pleat. Continue folding around the perimeter, pleating the tortilla until you have a sealed package. Ensure the filling is completely enclosed.
Step 5: Cook the crunchwrap. Heat a non-stick skillet or griddle over medium heat. Place the crunchwrap seam-side down on the hot skillet. Cook for 3-4 minutes until golden brown and crispy.
Step 6: Flip and finish. Carefully flip the crunchwrap and cook for another 3-4 minutes on the other side until golden and the marshmallows and chocolate are melted and gooey.
Step 7: Serve immediately. Transfer the S'mores Crunchwraps to a plate, let cool for a minute or two (the filling will be very hot), then slice and enjoy!
