Preheat oven to 375F, and line two cookie sheets with parchment or silicone liners.
In a medium bowl, stir together the cake mix, 2 eggs, vegetable oil, and lemon extract until a soft dough forms.
Place the powdered sugar in a small bowl. Using a spoon or cookie scoop, make balls of dough about 2 tablespoon big, and roll into the powdered sugar. Shake off the excess, and place on prepared pan, about 2 inches apart from each other.
Bake for 9-11 minutes, until puffy, dry, and the powdered sugar has cracked.
Serve immediately or store at room temperature.
