  1. Preheat oven to 350 degrees. Line 9 1/2"x13" baking pan {1/4 sheet pan size} with parchment paper, lightly spray with nonstick cooking spray and set aside.
  2. In medium saucepan, melt oil, chocolate chips, and cocoa together over medium low heat. Remove from heat and stir in sugar, eggs, vanilla and zucchini. Stir in dry ingredients, then pour into prepared pan. Spread out evenly and bake 15-20 minutes or until toothpick comes out clean when inserted in the middle. {A few moist crumbs is fine.}
  3. While brownies are baking, melt butter, cocoa powder, chocolate chips and milk together and simmer gently 1 minute. Remove from heat, then whisk in vanilla and powdered sugar.
  4. Once brownies are pulled from the oven, pour hot frosting over bars immediately. Spread to smooth, if needed. Cool 5-10 minutes before cutting into pieces and serving.
