1/2 cup granulated sugar

2 large eggs

2 teaspoons vanilla extract

2 1/4 cups all-purpose flour

1 teaspoon baking soda

1/2 teaspoon salt

2 cups mini marshmallows

2 cups crispy rice cereal

1. Cream the butter, brown sugar, and granulated sugar until light and fluffy.

2. Add eggs one at a time, then mix in vanilla extract.

3. In a separate bowl, whisk together flour, baking soda, and salt. Gradually combine with the wet mixture.

4. Fold in mini marshmallows and crispy rice cereal gently.

5. Scoop dough onto lined baking sheet, spacing evenly.

6. Bake at 350°F (175°C) for 10–12 minutes until edges are golden.
