Line a baking sheet with wax paper and set aside. In a medium-sized pot, melt butter over medium heat. Add 4.5 cups of your mini marshmallows and stir until completely melted. Remove from heat.

Add rice cereal to the melted marshmallow and fold. Continue folding until both ingredients are completely combined.

Shape the cereal treats into flat circles, about ½ inch in thickness and 3 inches in diameter. Curl each one around a wooden dowel. Place on lined baking sheet and allow to set.

Once your taco-shaped cereal treats are set, add a layer of chocolate buttercream in it. Then, add a layer of graham cracker crumbs and mini marshmallows. Top with chocolate syrup and enjoy!
