Preheat the Oven: Preheat your oven to 375°F (190°C).
Cream Butter and Sugars: In a mixing bowl, cream together the butter, granulated sugar, and brown sugar until light and fluffy.
Add Egg and Vanilla: Beat in the egg and vanilla extract until well combined.
Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
Mix Wet and Dry Ingredients: Gradually add the dry ingredients to the wet ingredients, mixing until just combined.
Add Rice Krispies and Chocolate Chips: Fold in the Rice Krispies cereal and chocolate chips.
Scoop and Bake: Using a medium cookie scoop, drop dough onto a parchment-lined baking sheet, spacing cookies about 2 inches apart. Bake for 8-10 minutes, or until lightly golden brown.
Cool: Allow cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack to cool completely.
Notes
For a festive twist, try adding butterscotch chips, peanut butter chips, or M&M candies.
To make gluten-free, substitute the all-purpose flour with almond flour or coconut flour.
For a dairy-free version, use dairy-free chocolate chips and a butter substitute.
