Slice pound cake into 4 (1-inch) slices. With a medium-sized heart-shaped cookie cutter, cut out hearts from each slice of pound cake. Set aside.
In a medium bowl combine 1/2 the raspberries and the sugar. Crush berries with a fork. Add remaining raspberries to the bowl. Add the lemon juice and mix well. Whip chilled cream until the soft peak stage.
Using 2 dessert plates, place 1 heart on each plate. Pour 3/4 of the raspberry mixture over each cake. Cover cakes with another pound cake heart. Top with whipped cream and remaining raspberry mixture.
