Stir together graham cracker crumbs, Splenda Magic Baker Sweetener, and melted spread. Divide graham cracker mixture among 12 mini-parfait glasses.
In a small bowl, add cornstarch and 2 tablespoons cold water, stirring until cornstarch is fully dissolved. Set aside.
In a small saucepan, add 1 cup finely sliced strawberries along with sweetener and ¼ cup water and bring to a boil. Using the back of a fork, gently mash strawberries up against the side of the pan. Reduce heat to medium, and stir in cornstarch mixture. Cook, stirring constantly, and bring mixture back to a low boil. Cook just until mixture thickens.
Pour strawberry sauce over the rest of the sliced strawberries and lemon zest and fold to combine. Divide strawberry mixture into parfaits, carefully spooning it over the crust layer. Refrigerate 1 hour or until serving.
Top with sugar-free whipped topping or vanilla yogurt and a strawberry if desired!
Note
Pie Parfaits are perfect for a summer party, bridal shower, or brunch.
