I’ve been baking these flourless chocolate cookies for years, ever since I came across François Payard’s famous chocolate walnut cookies.

They remind me of brownies, with their thin, crackly tops and chewy centers. I especially like making them around Christmas to share with friends and family, or whenever I have leftover egg whites from another recipe.

Recipe Highlights

  • Simple to make: No mixer needed, and the batter takes a few minutes to prepare.
  • Rich and chocolatey: Full of chocolate flavor from cocoa powder and chocolate chips.
  • Perfect for gifting: Great for Christmas cookie boxes alongside cantucci and baci di dama.
  • Customizable: Add chopped nuts or swirl in peanut butter.
  • Naturally gluten-free: Made without flour, so they’re a great option for anyone avoiding gluten.

For more gluten-free desserts, try my tofu chocolate pudding or 2-ingredient chocolate mousse.

Key Ingredients & Substitutions

  • Powdered sugar: Also called confectioners’ or icing sugar, it helps give the cookies their structure. Sift it before mixing, and don’t substitute granulated sugar, honey, or liquid sweeteners.
  • Cocoa powder: Both natural and Dutch-process work well. Dutch-process gives a darker color and milder flavor. I usually use Hershey’s Special Dark.
  • Egg whites: Fresh or from a carton. One large egg white equals about 2 tablespoons (30 g). Whole eggs or flax eggs won’t give the same texture.
  • Chocolate chips: You can also leave them out or replace them with chopped walnuts, pecans, or hazelnuts.
  • Vanilla extract: Almond, peppermint, or orange extract are good alternatives.
  • Salt: A pinch helps balance the sweetness and brings out the rich chocolate flavor.

How to Make Flourless Chocolate Cookies

  1. Mix the batter: Whisk together the powdered sugar, cocoa powder, and salt. Add the vanilla and one egg white, stirring until thick and glossy. If needed, add the second egg white a little at a time, then fold in the chocolate chips.
  2. Scoop and bake: Drop spoonfuls of batter onto a prepared baking sheet, leaving space between them. Bake at 350°F (175°C) for 12–14 minutes, until the tops are slightly cracked.
  3. Cool completely: Leave the cookies on the baking sheet until they’ve firmed up, then gently remove them.

Elena’s Tips

  • Measure carefully: Use a kitchen scale to measure the powdered sugar and cocoa powder accurately.
  • Start with one egg white: Add the second a little at a time only if the batter is too thick.
  • Don’t overmix: Stir just until everything is combined.
  • Prepare the baking sheet: Line it with parchment paper and lightly spray with nonstick cooking spray.
  • Keep the cookies even: Use a cookie scoop or small ice cream scoop to make them the same size so they bake evenly.
  • Leave enough space: These cookies spread during baking, so don’t crowd the tray.
  • Don’t overbake: Remove them when the tops are cracked and the centers are still soft.
  • Cool completely: The cookies are delicate while warm. Let them firm up before removing them from the baking sheet.

Troubleshooting

  • Cookies spread too much: Too much egg white can make the cookies spread. Add the second egg white a little at a time.
  • Cookies are dry: They may have baked too long. Check them at 12 minutes.
  • Batter is too runny: You may have added too much egg white. The batter should be thick enough to scoop, not pour.
  • Cookies stick to the baking sheet: Let them cool completely, then gently lift them with a thin metal spatula.

Storage & Freezing

Storage: Keep the cookies in an airtight container at room temperature for up to 4 days. They taste even better the next day.

Freezing: Once completely cooled, freeze the baked cookies in a freezer-safe container or bag for up to 3 months. Thaw at room temperature. They may soften slightly after thawing.
