Frozen Lemonade No-Bake Cupcakes

Cut pound cake into 18 slices, about 1/3-inch thick. Using a 1 ¾-inch-round cookie cutter, cut slices into rounds (scraps can be discarded or saved for another use). Place cake rounds into 18 paper cupcake liners; place on baking sheet.

Beat whipping cream in a medium mixer bowl until soft peaks form. Add lemon juice; beat until mixture is stiff. Fold in sweetened condensed milk and grated lemon peel. Spoon evenly into paper liners.
