  5. Place them in the oven and let them bake for 8 to 10 minutes, they will look light and white, they won’t necessarily get golden, so remove them from the oven once the timer is off.
  6. Let them cool for a couple of minutes and then prepare your icing. Use a spoon to spread your icing, and dust some crushed crackers for garnishing. Wait for the icing to harden before eating.

These cookies are so easy to make and so nice and soft, make sure they don’t overbake as it will result in really hard and crunchy cookies and not the nice and melty texture that they should have. So remove them looking light and white, avoid brown edges, as this will be a sign of overcooked cookies.

Preferably to consume the same day, as they won’t have the same melty consistency if you freeze them. These are refreshing, quick to make, and perfect for the summer days. These lime cookies are like a taste of heaven in your mouth. Enjoy!
