The Pioneer Woman's St. Patrick's Day Pie requires just four ingredients, including mint ice cream, mint chocolate sandwich cookies, whipped cream, and store-bought chocolate cookie pie crust. To create the pie, use 1.5 pints of mint chocolate chip ice cream and 1.3 cups of crushed Oreos for the topping, then add a layer of whipped cream and more crushed cookies for another two hours. The recipe is available on The Pioneer Woman Magazine.
