A melted butter and marshmallow mixture binds crisp rice cereal into soft, chewy squares. Use gentle heat to keep the marshmallows from hardening, then work quickly once the cereal goes in. Press the mixture lightly into a lined pan; heavy packing makes dense bars. Allow it to set at room temperature before cutting, rather than chilling it for hours. Line a 23 cm square pan with parchment and lightly grease it. Melt butter in a large heavy saucepan over very low heat; add marshmallows and stir until just smooth, then take off heat. Stir in vanilla and crisp rice cereal quickly until evenly coated. Transfer to lined pan and press gently into an even layer without compacting tightly.
