Ingredients
1 box (18 oz / about 510 g) brownie mix [provides the rich chocolate base and fudgy structure for these chocolate brownie cookies]
1/2 cup (about 60 g) all-purpose flour [adds stability to the thick dough, preventing spreads and ensuring cookie shape]
2 large eggs [act as binders for lift and moisture, creating that signature fudgy center]
5 tablespoons (75 ml) vegetable oil [delivers chewiness and tenderness without butter]
1 tablespoon (15 ml) water [helps blend the sticky dough smoothly]
1/2 cup (about 85 g) chocolate chips [melts into pockets of intense chocolate flavor]
3/4 cup (about 90 to 100 g) optional add-ins (walnuts, peanut butter chips, etc.) [customizes texture and taste bursts]
Instructions
1-First Step: Mise en Place Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper. Measure out all ingredients: 1 box brownie mix, 1/2 cup flour, 2 eggs, 5 tbsp oil, 1 tbsp water, 1/2 cup chocolate chips, and 3/4 cup add-ins. For vegan or gluten-free brownie mix cookies, prep flax eggs or grab GF mix now. This quick setup keeps things speedy.
2-Second Step: Combine Dry and Wet In a large bowl or stand mixer with paddle attachment, add everything: brownie mix, flour, eggs, oil, water, chocolate chips, and add-ins. Mix until fully combined. The dough stays thick and sticky, perfect for fudgy brownie cookies. Skip whisks; use paddle or hand mixer beaters. For low-calorie, add 1 tbsp plant milk if stiff.
3-Third Step: Fold-Ins and Portioning Gently fold in any extra chocolate chips or nuts if not already added. Use a small cookie scoop (1.5 tbsp) to drop dough 2 inches apart on the sheet. Smaller scoops bake faster; medium ones need 1-2 extra minutes. This portions soft and chewy brownie mix cookies evenly.
4-Fourth Step: Shape and Chill (Optional) The thick dough needs no chilling; bake right away for 15-minute treats. If too sticky, chill 15 minutes for easier handling and thicker fudgy brownie cookies. For busy schedules, skip it no problem.
5-Fifth Step: Bake with Timing and Temperature Bake at 350°F (175°C) for about 8 minutes. Check small scoops early; gas ovens hit 8 minutes, electric 9-10. Done when a thin film tops the surface, no gloss, but darker ripples remain. Pull slightly underbaked for fudgy centers. Convection: drop 25°F and check 1 minute early. High-altitude: add 1-2 tbsp flour.
6-Sixth Step: Cool and Finish Rest cookies on the pan several minutes to set, then move to a rack. Finish with powdered sugar dust or flaky salt. Serve warm for gooey bliss.
7-Final Step: Serving and Storage Notes Enjoy at room temp or warm. Reheat 10-15 seconds in microwave. Store airtight at room temp up to one week. Perfect for travelers or apartment dwellers.

⏰ Timing is crucial: small scoops in gas ovens often bake in about 8 minutes; electric ovens may need 9-10 minutes
🧁 Some brownie mixes that lack baking soda can produce flat cookies; in those cases, add 1 teaspoon baking soda to the dry mix
🍫 Because the dough is thick, chilling is unnecessary; you can mix and bake within about 15 minutes
