In a large bowl, whisk together flour, brownie mix, baking powder, baking soda and salt until evenly combined. Beat in eggs, milk and vanilla. Fold in chocolate chips.
Heat a large nonstick pan over medium heat. Grease the pan with cooking spray, then spoon about ¼-cup pancake batter into the pan. When little bubbles appear and start to pop, flip (about 1-2 minutes). Cook until browned on both sides.
Drizzle with chocolate syrup and top with sprinkles, if desired.
