Pour in mini marshmallows and stir until melted. Season with a pinch of salt if desired. Remove from heat and stir in cereal until it's fully coated in marshmallow.
Line a bowl with plastic wrap, then press Rice Krispie treat mixture into the inside of the bowl to create a new bowl. Repeat until you have used up all of the Rice Krispie mixture, then freeze bowls, 1 hour.
Pop Rice Krispie treat shells out of the bowls and serve with your favorite ice cream.
