Mix softened vanilla ice cream with partially thawed pink lemonade concentrate. I just let them both sit on the counter for 10 minutes while I mashed Arrowroot cookies and mixed them with melted butter until moist. With a little bit of brown sugar too. The recipe called for graham crackers but the arrowroot was nice and calm.
Push into wax paper lined casserole dish and put in freezer while you mash and mix ice cream and lemonade. Once just combined smooth onto crust, cover loosely with plastic wrap. Freeze for 6-8 hours. Cut with a large pizza cutter or cookie cutter. Run cutter under warm water before slicing.
