  • 1 ¾ sticks unsalted butter
  • 1 cup white sugar
  • 1 cup light brown sugar packed
  • 1 egg
  • 1 egg yolk
  • 1 tablespoon vanilla extract
  • ½ teaspoon baking powder
  • ¾ teaspoon baking soda
  • pinch nutmeg
  • 1 teaspoon kosher salt
  • 2 cups all-purpose flour
  • 1 ⅓ cup dark chocolate chips
  • 20 marshmallows


  • Place your marshmallows in the freezer for at least 1 hour.
  • In a small saucepan over medium-low heat, melt the butter. Once melted, increase the heat to medium and let the butter begin to foam. Keep cooking and stirring with a spatula, until the butter begins to brown and gives off a nutty smell (2-3 minutes). Pour into the bowl of a stand mixer, making sure you scrape out all of the brown butter stuck at the bottom of the pan. Let cool.
  • Add the sugars, salt, nutmeg, vanilla, baking soda, and baking powder to the stand mixer and beat with the paddle attachment. Beat for about 5 minutes until it is light and fluffy. Add the egg + yolk, and beat until the batter is smooth
  • Add in the flour and beat until smooth, but don’t overmix. Fold in the chocolate chips, but keep a small handful to the side for later.
  • Form the dough into balls (about 2 ½ tablespoon each), and press each one flat, then place the marshmallow. Fold the dough over the marshmallow.
  • Place the cookie dough balls on a large plate or baking sheet lined with parchment paper. Chill for at least 1 hour or up to overnight. You can place in a freezer bag and freeze for later if you wish!
  • Heat oven to 350°F/180°C and line three baking trays with parchment paper.
  •  Place the cookie dough balls on your baking sheet, leaving at least 2 inches between them. Bake the trays one at a time in the middle rack. Bake for 10-12  minutes for soft cookies, a minute or two longer if you want them crispier. Once out of the oven, place your extra chocolate chips on top. Allow the cookies to cool for 5-10 minutes before using a spatula to carefully take them off and place on a wire rack to cool completely.


My recipes have been developed and tested in metric grams. I highly recommend using a weighing scale and measuring out your ingredients the metric way. Just click on ‘Metric’ above the ingredients. 
Butter: I use European style butter, like Kerry Gold, in my recipes. This will make your finished bake much creamier and richer.
Salt: If you don’t have kosher salt, halve the amount of salt called for in the recipe. 1 teaspoon kosher salt = ½ teaspoon fine salt.
Storage: keep the baked cookies in an airtight container for up to 5 days at room temperature. Freeze unbaked cookie dough balls, when ready to bake just bake for an extra minute or two.
