Method
In a large mixing bowl, combine the egg, oil, water, vinegar, sugar, salt, and mahlep. Whisk until well combined.
Stir in the cornmeal first, then add the baking powder and the all-purpose flour gradually.
Knead until you have a smooth dough that is slightly firmer than bread dough and doesn't stick to your hands.
In one shallow bowl, mix the water and molasses. Place the toasted sesame seeds in another bowl.
Pinch off tiny, marble-sized pieces of dough and roll them into smooth balls.
Dip each ball into the molasses-water mixture to ensure the sesame seeds stick perfectly.
Roll the wet ball in the toasted sesame seeds until completely covered.
Arrange the bites on a baking sheet lined with parchment paper.
Bake in a preheated oven at 170°C (340°F) for 20–25 minutes until golden brown and crispy.
Notes
For the most authentic flavor, ensure your sesame seeds are well-toasted before coating the cookies. If you can't find Mahlep, you can omit it, but adding it provides that signature "Turkish bakery" scent that defines this recipe.
