Beat all ingredients except chocolate chips together until stiff peaks form. Fold in one cup of chocolate chips. Drop by spoonfuls (small) on foil-covered pans. Preheat oven to 350 degrees. Put kisses in oven and Immediately Turn Oven Off. Leave in oven at least 5 hours or overnight.

(note: my mother in law makes these with little mint chocolate chips in them, and says making it both ways is quite a treat!)
