1tablespoonwhole milk or heavy cream,at room temperature
2teaspoonspure vanilla extract
1 1/2cupscrispy rice cereal,plus extra for topping the cookies
1cupmini marshmallows
Flaky sea salt,for sprinkling on cookies
Instructions
In a medium saucepan, melt the butter over medium heat. Continue cooking, stirring frequently, until the butter foams and turns golden brown with a nutty aroma. This will take 5 to 7 minutes. Remove from heat and pour into a bowl to cool. I place the bowl in the refrigerator for 15 to 20 minutes.
In a medium bowl, whisk together the flour, baking soda, and sea salt. Set aside.
In a large bowl, combine the browned butter, brown sugar, and granulated sugar. Whisk until smooth and glossy. Add the eggs, milk or heavy cream, and vanilla extract. Whisk until fully combined and the mixture is thick and creamy.
Add the dry ingredients to the wet ingredients and stir until just combined, do not overmix.
Gently fold in the crispy rice cereal and mini marshmallows.
Cover and chill the dough for at least 2 hours (or up to 24 hours).
When ready to bake, preheat the oven to 350°F and line baking sheets with parchment paper.
Pour about 1/2 cup of crispy rice cereal in a bowl. Scoop the dough into cookie balls, about 2 1/2 tablespoons per cookie. Roll into smooth balls. Dip the tops extra crispy rice cereal. Place on the prepared baking sheets, spacing them about 2 inches apart.
Bake for 10 to 12 minutes, or until the edges are set and lightly golden but the centers are still soft.
Remove from the oven and sprinkle with flaky sea salt. Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.
