No-Bake Marshmallow Crispy Squares

In a large saucepan over low heat, melt the butter.

Add the marshmallows and stir until fully melted and combined. Cook for 2 minutes longer, stirring constantly.

Remove from heat and stir in the crispy rice cereal until evenly coated.

Press the mixture evenly and firmly into a buttered 9x13-inch pan using a buttered spatula or waxed paper.

Let it cool before cutting into 2-inch squares.
