Add the rolled oats and pecans to a small food processor. Pulse until the mixture looks like coarse crumbs.
Transfer the oat and pecan mixture to a bowl. Add cinnamon, melted coconut oil, and 2 tablespoons sweetener or honey. Stir until evenly moistened.
Divide the crust mixture between small serving cups or jars. Press it down gently to form a base.
Add the softened light cream cheese to a large mixing bowl. Beat or whisk until smooth.
Add the vanilla Greek yogurt, vanilla extract, vanilla whey protein, and 1/4 cup sweetener, honey, or agave. Mix until smooth and creamy.
Spoon the filling over the crust layer and smooth the tops.
Refrigerate for at least 2 hours, or until cold and slightly set.
Top with berries or mixed fruit before serving.
