For a lighter shortcake, make sure to handle the dough gently to avoid overworking it. Overmixing can result in a tough texture. Also, try to use fresh, ripe strawberries for the best flavor. If you want a sweeter shortcake, you can increase the sugar in the dough. The whipped cream can also be flavored with a hint of lemon zest or a few drops of almond extract for extra depth of flavor.
