1 (19.5 to 19.8 ounce) package brownie mix
1/3 cup vegetable oil or melted unsalted butter
2 large eggs
1 1/2 cups semisweet chocolate chips or chunks1 cup chopped nuts, any variety, sprinkled on top of cookies before baking (optional)
Preheat oven to 350 degrees F. Spray cookie sheets with nonstick cooking-spray.
In a large mixing bowl combine brownie mix, oil, and eggs with wooden spoon until just blended and all dry ingredients are moistened; stir in chocolate chips. Drop dough by heaping tablespoonfuls, 2 inches apart, onto prepared cookie sheets. Sprinkle with nuts, if desired.
Bake 11—14 minutes until cracked in appearance and just barely set at center when lightly touched. Cool 1 minute on sheets. Transfer to wire racks with spatula and cool completely.
