Frequently Asked Questions
Can I use a different size brownie mix?
Yes, you can use a larger or smaller box, but you’ll need to adjust the other ingredients proportionally. A standard family-size box is about 18 ounces. If you use a larger box (like 19.5 ounces), you may want to increase the flour slightly and add an extra egg yolk for moisture. If you use a smaller box, reduce the flour and oil slightly. The dough should be thick, scoopable, and hold together when pressed. If it seems too wet, add a little more flour. If too dry, add a tiny splash of milk. The recipe is forgiving, so trust your instincts and adjust as needed. You can also find many brownie mix cookie recipes online that are specifically tailored to the size of the mix you have.
Can I make these cookies without the extra flour?
You can, but the cookies will spread much more and be thinner and crispier, almost like a lace cookie. The extra flour gives the cookies structure, so they bake up thick and chewy. If you prefer a thinner, crispier cookie, you can omit the flour, but keep a close eye on the baking time—they’ll likely need only 6–8 minutes. Some people actually prefer this version. If you’re using a brownie mix that already contains extra thickeners, you might get away with less flour. Experiment and see what texture you like best. The recipe is flexible enough to accommodate both preferences.
Why did my cookies turn out cakey instead of fudgy?
Cakey cookies can result from overmixing the dough, overbaking, or using too much flour. Be sure to mix just until the ingredients are combined, and avoid overbaking—the cookies should look slightly underdone in the center when you pull them from the oven. Also, make sure you measure the flour accurately; too much flour can create a drier, cakier texture. Using oil instead of butter also tends to produce a fudgier cookie, as butter contains more water. If you prefer an even fudgier texture, you can replace the oil with an equal amount of melted butter, but be aware that butter can cause the cookies to spread a bit more. The key is to treat the dough gently and to respect the power of underbaking.
Can I make these dairy-free?
Yes. Many brownie mixes are accidentally dairy-free (check the label, but a lot of them contain no milk products). Use a neutral oil like canola or vegetable oil instead of butter. The eggs are not dairy. If the mix contains chocolate chips that are not dairy-free, simply use a dairy-free mix or pick out the chips and add your own dairy-free chocolate chips. The rest of the ingredients are naturally dairy-free. The cookies will be just as fudgy and delicious. You can also use a dairy-free brownie mix to be sure. This is a great option for those with dairy allergies or lactose intolerance. No one will be able to tell the difference.
How do I get that shiny, crackled top on the cookies?
The shiny, crackled top is a hallmark of brownies and brownie-based cookies. It comes from dissolving the sugar in the brownie mix with the eggs and oil. To enhance this effect, you can beat the eggs and oil together until they’re slightly frothy before adding the dry mix. Chilling the dough also helps, as it slows the spreading and allows the top to set into that beautiful crackle. Avoid overmixing, which can incorporate too much air and disrupt the crackle. The brownie mix is already formulated to create that shiny top, so following the recipe as written should give you great results. If your cookies don’t have the crackled top, they’ll still taste amazing—it’s primarily a cosmetic feature. But that glossy, crackled surface is part of what makes them so irresistible.

Prep Time:
10 minutes
Chill Time:
15–20 minutes
Cook Time:
8–10 minutes
Total Time:
35–40 minutes
Yield:
20–24 cookies
Ingredients
- 1 box (18 oz) brownie mix (any variety)
- ¼ cup all-purpose flour
- 2 large eggs
- ⅓ cup vegetable oil (or melted unsalted butter)
- Optional: 1 cup chocolate chips, ½ cup chopped nuts, 1 teaspoon vanilla extract, or 1 teaspoon instant espresso powder
- Optional for topping: flaky sea salt
Instructions
- Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
- In a large bowl, whisk together the brownie mix and flour to break up any lumps. Add the eggs and vegetable oil (or melted butter). Stir with a spatula or wooden spoon until a thick, sticky dough forms. If the dough seems too dry, add a teaspoon of water; if too wet, add a little more flour. Fold in any desired mix-ins.
- Cover the bowl and refrigerate the dough for 15–20 minutes. This helps prevent the cookies from spreading too much.
- Scoop the chilled dough by rounded tablespoons (about 1½ tablespoons each) and place on the prepared baking sheets, leaving about 2 inches between each cookie. Gently flatten the tops just slightly with your palm.
- Bake for 8–10 minutes, until the edges are set and the tops are shiny and crackled. The centers may look slightly underdone. Do not overbake. If desired, sprinkle with flaky sea salt immediately after removing from the oven.
- Cool on the baking sheets for 5 minutes, then transfer to a wire rack to cool completely. Store in an airtight container at room temperature.
Notes
- Use any flavor of brownie mix: dark chocolate, milk chocolate, or even red velvet. The recipe works with them all.
- Chilling the dough is essential for thick, chewy cookies. If you’re short on time, pop the bowl in the freezer for 5–10 minutes.
- For extra fudgy cookies, use melted butter instead of oil. For a dairy-free version, use oil and ensure your brownie mix is dairy-free.
- Dough balls can be frozen on a baking sheet, then stored in a freezer bag for up to 3 months. Bake directly from frozen, adding 2–3 minutes to the bake time.
- Store baked cookies in an airtight container at room temperature for up to 5 days, or freeze for up to 3 months.
