I am a big fan of key lime pie but sometimes they are too sweet or too tart. These are just right and just the right size too. Being as hot as it has been, these little treats are so refreshing and so easy to make as well. Individual Key Lime Pies 1 1/2C graham cracker crumbs, 3 TB sugar, 1/3 C melted butter, 3 eggs whites, beaten, 2 (14oz) sweetened condensed milk, 3/4 C lime juice, 1T lime zest, and 1/3 C nonfat greek yogurt. Mix graham cracker crumbs with melted butter and sugar. Press 1 TB graham cracker mixture into the bottom of a cupcake liner or mini pie pan. Bake for about 8 minutes. In another bowl, mix together egg whites, condensed milk, lime juice, zest and greek yogurt. Fill cupcakes or pine tins about 3/4 full with mixture. Bake for 13-15 minutes and cool completely. Top with a whip cream topping and then garnish with a lime wedge to decorate.
