Instructions

• Preheat the oven to 350°F. Line one or more baking sheets with parchment paper and set aside.
• In a large mixing bowl, whisk together the 18-ounce box brownie mix and 1/4 cup all-purpose flour until evenly combined.
• Add 1/3 cup vegetable oil and 2 large eggs to the dry mixture. Stir with a spatula or spoon until a thick, uniform batter forms.
• Stir in 1/2 cup of the 1 cup semi-sweet chocolate chips; reserve the remaining 1/2 cup for topping.
• Portion the dough into about 1-inch balls (use a small cookie scoop or a rounded teaspoon). Roll each portion between your palms to smooth, and place the balls on the prepared baking sheets about 2 inches apart.
• Press several of the reserved chocolate chips into the top of each dough ball.
• Bake in the preheated 350°F oven for 8 to 11 minutes, until the edges are set and the centers look slightly undercooked.
• Remove the baking sheets from the oven and let the cookies cool on the sheets until firm enough to lift.
• Transfer the cookies to a wire rack to cool completely before serving.
