Ingredients
Scale
Wet Ingredients
- 1 cup unsalted butter
- 1 cup brown sugar
- 1/2 cup granulated sugar
- 2 teaspoons vanilla extract
- 1 large egg
Dry Ingredients
- 1 3/4 cups all-purpose flour
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
Add-ins
- 1 1/2 cups mini marshmallows
- 1 1/2 cups Rice Krispies cereal
Instructions
- Cream the sugars and butter: In a large bowl, beat the unsalted butter with brown sugar and granulated sugar until the mixture is light and fluffy, creating a smooth base for the cookie dough.
- Add egg and vanilla: Mix in the large egg and vanilla extract until fully combined, ensuring the wet ingredients are well incorporated.
- Combine dry ingredients: In a separate bowl, whisk together the all-purpose flour, baking soda, and salt to evenly distribute the leavening agents and seasoning.
- Mix dry into wet: Gradually add the dry ingredient mixture to the wet ingredients, stirring just until combined to avoid overmixing and developing too much gluten.
- Fold in marshmallows and cereal: Gently fold mini marshmallows and Rice Krispies cereal into the cookie dough to evenly distribute the add-ins without crushing them.
- Chill the dough: Cover the dough and refrigerate for at least 30 minutes to firm it up, which helps the cookies keep their shape while baking.
- Scoop dough balls: Using a tablespoon or cookie scoop, portion out 2-tablespoon-sized balls of dough onto a parchment-lined baking sheet, spacing them evenly apart.
- Bake the cookies: Bake in a preheated oven at 350°F (175°C) for 10–12 minutes until the cookie edges are golden brown and the centers are still slightly soft and underbaked for a chewy texture.
- Cool on baking sheet: Let the cookies cool on the baking sheet for 5 minutes to firm up before transferring them to a wire rack to cool completely.
- Serve and store: Enjoy the cookies warm or allow them to fully cool before storing in an airtight container to maintain freshness.
Notes
- Chilling the dough is crucial for maintaining cookie shape and enhancing flavor.
- Do not overbake; cookies should remain soft in the center for the best texture.
- Use mini marshmallows to ensure even distribution with the Rice Krispies cereal.
- If you prefer less sweetness, adjust the sugar quantities slightly or try different types of sugars, such as coconut sugar.
- Store cookies in an airtight container at room temperature for up to 5 days.
