Notes

    • Use 60% cacao or higher bittersweet chocolate: Chocolate with a high cacao will give these cookies a rich, chocolaty flavor and result in a smoother melt. Because we’re adding sugar, we don’t need to worry about the chocolate being bitter.

    • Bringing cold eggs to room temperature quickly: If you need to bring your eggs to room temperature quickly for this recipe, fill a bowl with hot water from your tap and place the eggs in it for about 5 minutes.

    • Whip the eggs/sugar for the full 5 minutes: This is the step that gives the cookies their crinkled brownie appearance so be sure to whip for the full 5 minutes.

    • Scooping: Try to scoop the batter so that the marshmallow fluff is at the bottom of the scoop. This will ensure you get a nice visible swirl that will toast and that will keep it from sticking to the parchment which could potentially tear the cookie when it’s moved.

    • Fold in the dry ingredients: Once you whip the eggs and sugar, you want to minimize the amount of work the batter experiences so the eggs don’t deflate.

    • Storage: These cookies can be kept in an air tight container at room temperature for up to a week or frozen (I like to individually wrap mine in plastic wrap) for up to 6 months.
