I got this recipe from the TOH site..I just took them out of the oven...they are great! (Sorry, I didn't print out who posted it.)

1 c. butter (no subs) softened
3/4 c. packed brown sugar
1/3 c. sugar
1 egg
2 t. vanilla extract
2 1/4 c. all purpose flour
2 T. Nestle's Quik (choc. drink mix)
1 t. baking soda
1/2 t. salt
2 c. malted milk balls, crushed (Whopper's)
I did mine in the food processor.

With mixer, cream together sugars and butter. Beat in egg and vanilla. Combine the flour, Nestle Quik, baking soda , and salt. Add gradually to the creamed mixture. Stir in the malted milk balls. Shape into 1 1/2 in. balls and place 2 in. apart on greased baking sheets. Bake at 375 for 10-12 mins. (mine did not take that long)..Cool for 2 mins. before removing from pans. Makes about 3 doz.
