Peanut Butter Pie (Π)

What better way to celebrate Pi Day (3.14), which falls in the middle of National Peanut Butter Month, than with a luscious Peanut Butter Pie?  It's so simple and so rich that you'll want it more than once a year; but it's a very fitting dessert for March 14th.

Peanut Butter Pie

Prepared Graham Cracker Crust
8 oz. Cream Cheese, softened
1 c. powdered sugar
1 c. peanut butter
1 8-oz. carton whipped topping, thawed

Cream the cream cheese.  Add powdered sugar and peanut butter and beat until smooth.  Fold in cool whip.
Place in crust.  Refrigerate or freeze.

For added delight, add chopped peanut butter cup candies or chocolate chips; or drizzle melted chocolate on top.

Serve on Π Day to your friends/family/coworkers.  
NOTE: If you have no friends, this pie may help you to obtain friends. 
DISCLAIMER: Having never loved math, I do not observe this day because of 3.14159....But I love pie, and I'll take any excuse to make one.
