These 4-ingredient chocolate meringue cookies are the perfect fancy but easy dessert. Featuring a shatter-crisp exterior and a chewy, fudgy center, these naturally gluten-free treats deliver rich cocoa flavor in every airy bite.
Preheat oven to 225°F. Line a baking sheet with parchment paper. Set aside.
In the clean bowl of a stand mixer fitted with the whisk attachment, beat the egg whites on medium-high speed until foamy.
2 large egg whites
Add the cream of tartar, if using.
⅛ teaspoon cream of tartar
With the mixer still on medium-high speed, slowly add the sugar, about 1 tablespoon at a time. Adding all of the sugar should take about 2 minutes.
½ cup granulated sugar
Beat the egg white mixture until stiff peaks form.
Once the mixture has reached stiff peaks, gently fold in the cocoa powder. Make sure not to deflate the egg whites!
1½ tablespoons dark cocoa powder
Transfer the mixture to a piping bag. Pipe small dollops (about 1-inch in diameter) at least 1 inch apart on the prepared baking sheet.
Bake the meringues for exactly 1 hour. Turn off the oven and slightly open the oven door, but leave the meringues inside! Allow them to slowly cool to room temperature, about another hour.
Notes
*Cream of tartar is an optional insurance policy--it stabilizes the egg whites and adds volume.**Make sure to use high-quality cocoa for the best flavor.Tips:
Bake these cookies on a dry day; humidity will cause them to weep.
Thoroughly clean your bowl, wiping with lemon juice or white vinegar to remove any fatty residue that could inhibit the egg whites.
Add the sugar slowly to avoid deflating the egg whites.
To test for doneness, rub the meringue between your fingers. If it still feels gritty, keep beating. Once smooth, you can gently fold in the cocoa.
I like to double-sift the cocoa powder to ensure a smooth finish.
If you don't have a piping tip set, use a zip-top bag with the corner snipped off.
Don't make your meringues too big, or they will not dry properly.
Don't open the oven while they bake, or they could deflate.
Variations:
Mocha: Whisk in 1 tsp instant espresso powder with the sugar.
Chocolate Chip: Gently fold in ¼ cup mini chocolate chips after the cocoa.
Peppermint: Add ½ tsp peppermint extract with the cream of tartar.
Mexican Hot Chocolate: Add ½ tsp cinnamon and a pinch of cayenne with the cocoa.
Storage: Store meringue cookies in an airtight container at room temperature for up to 3 days.
