Make the crepe batter

• Whisk the milk, eggs, sugar and vanilla extract in a mixing bowl.
• Add the flour and melted butter and whisk until smooth.

Rest the batter

• Cover the batter and let it sit so the flour hydrates.

Cook the crepes

• Heat a buttered frying pan over medium heat.
• Pour in a thin layer of batter and swirl to coat the pan.
• Cook until set, then flip and cook the other side.

Fill with s'mores

• Scatter chocolate and marshmallows over each crepe.
• Fold the crepe and warm until the chocolate and marshmallows melt.

Serve

• Top the crepes with crushed graham crackers and serve warm.
