Press the crushed Oreos into the bottom of four one-cup serving glasses.
In a medium bowl, beat the cream cheese and butter together until creamy.
Turn the mixer to low and add the powdered sugar until it is completely combined. Fold in cool whip. Pipe or spread cheesecake mixture over the Oreo crust in each glass.
Spoon an even portion of chocolate pudding over the cheesecake mixture, then top each with whipped topping and chocolate shavings.
Refrigerate for about 30 minutes and serve cooled.
Notes
These chocolate cheesecake dessert cups start with a crushed oreo base, then piped with a smooth, no-bake cheesecake mixture. You can make your Oreo base as crushed or as whole as you desire.
