Ingredients
1 (18 ounce) box brownie mix
1/4 cup vegetable oil
2 large eggs
1/4 cup all-purpose flour
1 teaspoon vanilla extract
1 cup semisweet chocolate chips
1 extra egg yolk (optional, for extra tenderness)
Instructions
1-Preheat oven and prepare pan: Preheat oven to 350°F and line a baking sheet with parchment paper.
2-Make the dough: Combine brownie mix, oil, eggs, flour, and vanilla; mix until thick and smooth. Add an extra egg yolk for tenderness if desired.
3-Add chips and portion: Fold in chocolate chips, then scoop 1.5-inch dough balls and place 2 inches apart on the sheet.
4-Chill dough: Chill dough balls on the sheet in the fridge for 30 minutes to prevent spreading.
5-Bake cookies: Bake at 350°F for 8-10 minutes until edges are set and tops cracked. Add 1-2 minutes if needed.
6-Cool and finish: Cool on baking sheet for 10 minutes, then transfer to a wire rack. Press extra chocolate chips on top right after baking for decoration.

💡 Replace vegetable oil with melted butter for the chewiest cookie texture.
❄️ Do not skip the 30-minute chill—it keeps the cookies from spreading into flat puddles.
⏲️ Pull cookies when edges are set but centers look soft and gooey; they firm up as they cool.
