Prepare the cups by selecting three clear cups or glasses, ensuring they are cleaned and dried.

In a medium bowl, beat together the cream cheese, marshmallow creme, and Cool Whip until creamy and fluffy.

In a food processor, combine crushed graham crackers, flour, sugar, and melted butter. Pulse until crumbs form.

Layer the graham cracker crust in the bottom of each cup, pressing down to create a solid base.

Add a layer of the cheesecake mixture over the crust, smoothing the top.

Top the cheesecake layer with a colorful layer of mixed berries.

Repeat the layering process to create three layers in each cup.

Cover the parfaits and refrigerate for at least 1 hour before serving.
