For an extra layer of flavor, lightly toast the graham cracker crumbs in a dry skillet before adding them to the cake batter. If you don't have Zinfandel wine, you can substitute another red wine like Merlot or Pinot Noir. The macerated strawberries can be made a day in advance. For a non-alcoholic version, substitute the Zinfandel wine with an equal amount of grape juice or cranberry juice. Use high-quality, fresh strawberries for the best flavor. Garnish with fresh mint leaves or a dusting of powdered sugar for an elegant presentation.
