1. Make the Crepe Batter. Whisk the flour and eggs together in a large bowl. Gradually add the milk and water, stirring until smooth. Mix in the melted butter and salt. Let the batter rest for 15 minutes.

2. Cook the Crepes. Heat a non-stick skillet over medium heat. Lightly butter it. Pour 1/4 cup of batter into the center, tilting the pan to coat the surface evenly. Cook for about 2 minutes, flip, and cook for another minute. Repeat until all batter is used. Stack cooked crepes on a plate.

3. Create the Treat Filling. In a large saucepan, melt the 3 tbsp of butter over low heat. Add the marshmallows and stir until completely melted and smooth. Remove from heat and immediately stir in the cereal until well coated.

4. Assemble the Crepes. Place a crepe flat on a surface. Spoon a line of the cereal mixture down the center. Fold the sides over the filling, then roll it up like a burrito. Place it seam-side down.

5. Design the Web. Melt the chocolate chips. Transfer to a piping bag or a zip-top bag with a tiny corner snipped off. Pipe a spiral of chocolate onto each crepe. Immediately drag a toothpick from the center outwards to create the web effect. Let the chocolate set.
