Select 6 tall stemmed glasses (8-ounce wine glasses or champagne glasses are ideal).
In a small bowl, mix cherries, 2 tablespoons Splenda, and almond extract. Set aside.
In another small bowl, mix graham-cracker crumbs, 2 tablespoons Splenda, cocoa powder, and butter. Set aside.
In a medium mixing bowl, beat cream cheese with an electric mixer until creamy. Add sour cream and remaining Splenda (1/4 cup) and stir until smooth. Fold in whipped topping with a spoon.
In the bottom of each glass, place 1 tablespoon graham-cracker mix. Press down with spoon. Place about 3 tablespoons of cream cheese mix on top of each. (You will use only half of the cheese mixture for the 6 glasses). Divide the cherries among the glasses, placing them on top of the cream cheese layer. Add one more layer of cream cheese. Finish the parfait by topping each with 1 tablespoon of crumbs.
Enjoy immediately or place in the refrigerator until you are ready to serve.
