Lemon Icebox Pie

"Lemon Icebox Pie is a Southern dessert named “icebox” because in old times it was set in the refrigerator rather than baked. This is a no bake, eggless and lower-in-fat version. There are many variations of this recipe. Usually it is made using condensed milk. My version uses firm low-fat yogurt or Greek yogurt. I also added some lemon juice and finely grated lemon zest to give it more intense, tangy lemon flavor. The low-fat whipped topping helps to maintain a creamy, ice-cream like texture to the filling. This filling is poured into a cookie crumb crust made of graham crackers or other types of cookies, like vanilla wafer cookies. After refrigeration, Lemon Icebox Pie is served with whipped cream topping."
