These flourless chocolate cookies have crisp, crackly tops and soft, fudgy centers. Chewy, rich, and naturally gluten-free, they’re made in one bowl with just a few ingredients.
Preheat the oven to 350°F (175°C). Line a large baking sheet with parchment paper or a silicone baking mat. If you're using parchment paper, lightly spray it with nonstick cooking spray.
Make the cookie dough
In a large bowl, whisk together powdered sugar, cocoa powder, and salt.
Add the vanilla and one egg white, then stir until the batter is thick and fudgy. If it feels too dry, mix in the second egg white a little at a time.
Fold in the chocolate chips.
Scoop and bake
Use a cookie scoop to drop the batter onto your prepared baking sheet, leaving space between each cookie.
Bake for 12-14 minutes, until the tops look glossy and slightly cracked. Rotate the baking sheet halfway through.
Let the cookies cool completely on the baking sheet before removing them with a metal spatula.
Notes
Egg whites: Start with one and check the batter's consistency before adding more.
Cocoa powder: Natural or Dutch-process, both work.
Parchment paper: Even if it’s nonstick, give it a light spray to prevent sticking.
Spacing: These spread as they bake, so don’t crowd the tray.
Don’t overbake: They’re ready when the tops look dry. Centers will firm up as they cool.
Storage: Keep in an airtight container at room temperature for up to 4 days, or freeze for up to 3 months.
Gluten-free: Check that your powdered sugar and chocolate chips are certified gluten-free.
Dairy-freeoption: Swap the chocolate chips for chopped roasted nuts or dried fruits.
