Preheat the oven to 215 degrees fahrenheit.
Line a 9x13 baking sheet with tin foil and then place a sheet of parchment paper over the top of the foil.
Place the yogurt, cornstarch, and sugar in a small mixing bowl, and mix until fully combined.
2 tbsp Flavored or Plain Yogurt, 2 tbsp Cornstarch, 1 tbsp White Granulated Sugar
Add the egg whites and cream of tartar to a separate medium mixing bowl. Using the hand mixer, beat the egg mixture until it holds shape. Nice and thick.
2 Egg Whites, 1/4 tsp Cream of Tartar
Gently, very gently, add the yogurt mixture to the egg whites and lightly fold the ingredients together using a rubber spatula. Remain very gentle so the mixture holds its texture.
Using a spoon or frosting bag, make small dollops of the yogurt mixture on the prepared sheet. You don’t have to leave a ton of space between each dot. Just a little bit is perfect.
Bake for 30-40 minutes or until lightly golden brown on the bottom.
Remove and let chill on the pan for 15 minutes.
Eat right away or store in a sealed baggie or airtight container in the pantry. Enjoy!
