In a large mixing bowl, whisk together the eggs, flour, milk, honey, baking powder, and salt. Stir until you achieve a smooth, lump-free batter.
Fold in the crushed graham crackers for added flavor and texture.
Preheat your waffle iron, lightly greasing it if necessary, to prevent sticking.
Pour the batter into the hot waffle iron, filling but not overloading it. Cook for around 3-4 minutes, or until the waffles are golden brown and fluffy.
While the waffle is still warm, cut it in half and spread Nutella generously on both sides.
Layer one side with mini marshmallows. Fold the other half over to sandwich the marshmallows inside.
Place the sandwich back in the waffle iron and press for 3-4 minutes to melt the marshmallows and bind the layers.
Top the finished waffle with a drizzle of pancake syrup, a sprinkle of toasted coconut, and extra crushed graham crackers for the perfect finish. Serve immediately!
