1. Beat ice cream in a bowl just until softened. Fold in 3/4 cup sauce, leaving streaks. Transfer to a loaf pan; cover with plastic wrap. Freeze at least 2 hours and up to 2 weeks.

2. Toss strawberries with sugar, lemon juice, and salt in a bowl; let stand 30 minutes.

3. Slice cake 1/2 inch thick, then cut out 2 1/2-inch rounds with a cookie cutter. Place 2 scoops of ice cream in each serving glass. Add a pound-cake round, more sauce, and some sliced-strawberry mixture. Top with another scoop of ice cream, a dollop of whipped cream, and a whole berry; serve.
