Mom's Famous Peanut Butter Balls

My mom has been making these forever and they are always a huge hit!  They are simply delicious, and the recipe makes a ton so they're great for a cookie party or for Christmas favors.

Makes about 5 dozen

Ingredients:

1 stick butter
2 cups plain creamy peanut butter
1 box powdered sugar
1/2 tsp vanilla
1 large pkg semi-sweet chocolate chips
1/2 stick parrafin wax

Method:

Set butter out to soften.  Mix butter with peanut butter, vanilla and powdered sugar.  Form into small balls (smaller than a golfball) and chill.  In a double-boiler, melt chocolate chips and wax.  Dip balls into chocolate mixture with a toothpick and set aside on wax paper.  Store in refrigerator.
