Cornstarch gives the cookies their melt-in-your-mouth texture by softening the dough.

Can I skip the powdered lemonade mix?

Yes. It adds extra tang but lemon zest and powdered sugar are enough for a great coating.

How do I keep the cookies from spreading?

Chill the dough for 15–30 minutes before baking if your kitchen is warm or the dough is too soft.

Do these cookies have a crisp or soft texture?

They’re soft and tender, not crispy, with a slight crumbly bite.

Do I need to coat the cookies twice?
