1Heat oven to 375°F. In large bowl, mix eggs, 1 cup of the sugar, the butter and shortening. Stir in Bisquick mix and chocolate chips until dough forms.
2In small bowl, mix remaining 1/4 cup sugar, the cocoa and cinnamon. Shape dough into 1 1/4-inch balls. (If dough feels too soft for shaping, place in freezer 10 to 15 minutes.) Roll balls in sugar mixture. On ungreased cookie sheets, place balls 2 inches apart.
3Bake 9 to 11 minutes or until set. Immediately remove from cookie sheets to cooling racks. Store cooled cookies tightly covered.
