Talk about getting caught with your hand in the cookie jar.

The former finance director for the Girl Scout Council of Greater New York was charged yesterday with embezzling $310,000 from the nonprofit over two years.

Yaasmin Hooey, 35, of Manhattan, allegedly used the stolen loot to buy a $13,000 diamond ring, a cosmetic laser procedure, gym memberships, clothes, concert tickets and a cruise with her girlfriend, according to one law-enforcement source.

“Nonprofits are not personal cookie jars,” Manhattan DA Cyrus Vance said in a statement.

Hooey denied the charges.
