Chocoate Truffle Cookies

By popular request, here is the recipe for the cookies I made for the Mansfield Downtown Holiday Mingle last weekend. They are perfect for a cookie exchange because they make so many (you might even have some to keep!)
Enjoy!
Chocolate Truffle Cookies
Beat together: 1 1/4 c. softened butter, 2 1/4 c. confectioners sugar, 1/3 c. baking cocoa powder. Stir in: 1/4 c. sour cream, 1 Tablespoon good vanilla extract.
Stir in: 2 1/4 c. general purpose flour.
Mix in 2 c. semi-sweet chocolate chips.
Refrigerate for 1 hour. Pre-heat oven to 325 degrees F.
Scoop dough into 1" balls and dip tops in chocolate sprinkes (you will need approximately 1/4 c. of sprinkles for all of the dough). Place on ungreased cookie sheets about 2" apart and bake for 10-12 minutes or just until set. Let cool 5 minutes then remove to rack and let cool completely. Makes approximately 5 1/2 dozen yummy, fudgy cookies!
