Instructions:

1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with butter or nonstick spray. Line the pan with parchment paper, leaving some overhang on the sides, and grease the parchment paper as well. Set the pan aside.
2. In a large bowl, stir together the melted butter, both sugars, eggs, and vanilla extract until smooth and well combined.
3. Sift in the flour, cocoa powder, and salt into the bowl with the wet ingredients. Stir until just combined, being careful not to overmix. Fold in 1 cup of the chocolate chips until evenly distributed throughout the batter.
4. Spread the batter evenly into the prepared baking pan. Sprinkle the remaining chocolate chips on top of the batter.
5. Bake in the preheated oven for 25-30 minutes or until the brownies are just set. A toothpick inserted into the center should come out with a few moist crumbs attached.
6. Remove the brownies from the oven and allow them to cool completely in the pan before slicing and serving. This will help them set and become easier to slice into neat squares.
7. Enjoy! These fudgy cocoa brownies are best enjoyed with a cold glass of milk or a scoop of vanilla ice cream on top.

These one-bowl fudgy cocoa brownies are sure to become a favorite in your household. They’re incredibly simple to make yet yield deliciously rich and decadent brownies that everyone will love. Enjoy!
