Easy P.B. Cheesecake

This is an easier version of a peanut butter cheesecake that I posted a year ago.  It is excellent!  It also it a less expensive.  The other recipe is only slightly better so if you have the time and money use that one.  Here's the recipe.  I found it online somewhere...I don't remember where.

Ingredients:
1 package cream cheese, softened
1 cup white sugar
1 teaspoon vanilla extract
2/3 cup creamy peanut butter
1(8 ounce) container frozen whipped topping, thawed
1 graham cracker or Oreo pie crust

Directions:
1. Beat the cream cheese, sugar and vanilla together.  Add the peanut butter and mix well.  Fold in the whipped topping until completly blended.
2. Fill the pie crust with the peanut butter mixture and chill in the freezer until ready to serve.
