Making Rice Krispie Treats is straightforward. Follow these simple steps to ensure success:

1. Prepare the Pan: Grease a 9×13-inch baking dish with butter or line it with parchment paper for easy removal.
2. Melt Butter: In a large saucepan, melt the butter over low heat.
3. Add Marshmallows: Once the butter is melted, add the mini marshmallows to the saucepan. Stir continuously until the marshmallows are completely melted and smooth.
4. Add Vanilla and Salt: If using, stir in the vanilla extract and a pinch of salt to enhance the flavor.
5. Combine with Cereal: Remove the saucepan from the heat and quickly stir in the Rice Krispies cereal. Mix until all the cereal is evenly coated with the marshmallow mixture.
6. Press into Pan: Pour the mixture into the prepared baking dish. Using a buttered spatula or wax paper, gently press the mixture down evenly into the pan. Avoid packing too tightly.
7. Cool: Allow the Rice Krispie Treats to cool at room temperature for about 30 minutes or until set.
8. Cut into Squares: Once cooled, cut into squares or rectangles and serve.
