Tips
Repress the indentations while cookies are still warm from the oven to ensure they're deep enough for the filling.
Chill the key lime filling thoroughly before piping to prevent it from being too runny and overflowing the cookies.
Use a piping bag or small spoon to neatly fill the indentations without making a mess on the cookie surface.
