Ingredients
Scale
- ½ cup salted butter
- ¾ cup brown sugar
- ½ cup granulated sugar
- 1 large egg (room temperature)
- 1 teaspoon vanilla
- ½ tsp baking soda
- ¾ tsp salt
- 1 cup + 2 tbsp all-purpose flour
- 1½ cups rice krispie cereal
- ⅔ cup mini marshmallows
- flaked salt for topping
Instructions
- Preheat your oven to 350°F (175°C). While it's heating, line a baking sheet with parchment paper to prevent sticking and make cleanup easier.
- In a medium saucepan, melt ½ cup of salted butter over medium heat. Stir continuously until the butter foams and then turns a rich golden brown, about 5-7 minutes. Once browned, remove it from the heat and let it cool in the fridge or freezer for 10 minutes.
- In a mixing bowl, combine the cooled brown butter with ¾ cup brown sugar and ½ cup granulated sugar. Mix on low speed until well blended, which should take about 30 seconds.
- Add 1 large room-temperature egg and 1 teaspoon of vanilla to the mixture, mixing until smooth.
- Carefully add ½ tsp baking soda and ¾ tsp salt to the mixture, followed by 1 cup + 2 tbsp all-purpose flour. Mix just until combined; be cautious not to over-mix.
- Fold in 1½ cups of rice krispies and then ⅔ cup of mini marshmallows. Use a spatula to gently incorporate these ingredients without breaking the marshmallows.
- Using a 3 tbsp cookie scoop, portion out the dough onto the prepared baking sheet, leaving plenty of space between each cookie.
- Bake in the preheated oven for 10-13 minutes. Look for a light golden brown color around the edges while the centers should still appear slightly soft.
- Immediately after removing from the oven, sprinkle a pinch of flaked salt on top of each cookie for added flavor. Let the cookies cool on the baking sheet for 5 minutes before transferring them to a wire rack to cool completely.

Keywords: Be mindful of browning your butter; it's a delicate process. Use a cookie scoop for uniformity, and don't skip the flaked salt for enhanced sweetness. Watch the baking time closely to avoid overbaking.
