Ingredients

• 6 tablespoons Butter
• 10 cups Mini marshmallows
• 1 teaspoon Vanilla extract
• 6 cups Rice cereal (e.g., Rice Krispies)
• 0.25 teaspoons Salt (optional)

Directions

Step 1

Grease a 9x13-inch pan with butter or nonstick cooking spray. Set aside.

Step 2

In a large pot over medium-low heat, melt the butter, stirring frequently to avoid browning.

Step 3

Once the butter is fully melted, add the mini marshmallows to the pot. Stir constantly until the marshmallows are completely melted and smooth.

Step 4

Remove the pot from heat. Stir in the vanilla extract and salt (if using) until well combined.

Step 5

Gently fold in the rice cereal using a spatula or wooden spoon, ensuring all pieces are evenly coated with the marshmallow mixture.

Step 6

Transfer the mixture into the prepared pan. Use a greased spatula or lightly buttered hands to press the mixture evenly into the pan, without compressing it too firmly.

Step 7

Allow the marshmallow squares to cool at room temperature for about 30-45 minutes, or until set.

Step 8

Once cooled, use a sharp knife to cut into 16 squares or your desired size. Store in an airtight container for up to 3 days.
