If you are making the mini cups:
Layer 1 tablespoon graham cracker crumbs in glasses. Top with 1 to 2 tablespoons filling (pressed down).
Bake about 20 minutes, until top is firm to the touch and a toothpick inserted comes out clean. Top with 1 tablespoon fruit or whipped cream.
If you are making a pie:
Press ¾ cup graham cracker crumbs into the bottom of the prepared pie pan. Spoon filling on top. Bake about 25 to 30 minutes, until top is firm to the touch and a toothpick inserted comes out clean. Top with fruit or whipped cream.
Note: The parfaits freeze well. Serve parfaits with a variety of topping combinations.
