A fun crust of vanilla wafers is easy for kids to make and holds an eye-catching fluffy filling that's refreshing in summer. "Use different flavors of Kool-Aid to very the pie's taste," suggests Ledia Black of Pineland, Texas.
Pour milk into a small metal or glass bowl. Add beaters to the bowl. Cover and chill for at least 2 hours. Coat a 9-in. pie plate with cooking spray. Line bottom and sides of plate with wafers. Beat milk until soft peaks form. Add sugar and drink mix; beat until thoroughly mixed. Spoon over wafers; freeze for at least 4 hours. Garnish with whipped topping if desired.
