I can never choose between fudgy brownies and chewy cookies, so these Brownie Mix Cookies are my favorite shortcut to both. Rich, chocolatey, and dangerously easy to love, they disappear fast every single time.

Jump to Recipe

I’m obsessed with these brownie mix cookies because I get that dense, fudgy brownie bite in cookie form, with chewy edges that actually fight back a little. I love how rich they taste without feeling fussy, and yes, I absolutely want the crackly tops.

Every batch feels like my shortcut to serious chocolate cravings, especially when I toss in semisweet chocolate chips and let a boxed brownie mix do its thing. But the best part?

They taste like I tried way harder than I did. Thick, chocolatey, gooey in the center.

And dangerously easy to keep “testing” from the plate.

Print Recipe (No Advertisments)

Brownie mix does the heavy lifting, giving you that fudgy bakery-style cookie base.
Eggs help everything hold together and keep the cookies soft, not crumbly.
Vegetable oil brings that chewy, bendy middle you’ll want in every bite.
Vanilla makes the chocolate taste deeper, warmer, and just a little more homemade.
Chocolate chips add melty pockets, because more chocolate is basically the whole point.
Plus, a tiny pinch of salt keeps the sweetness from getting too loud.
Chopped nuts bring crunch, a little richness, and that classic brownie-shop vibe.

Ingredient Quantities

1 (18 to 20 ounce) boxed brownie mix

2 large eggs, at room temperature

1/3 cup vegetable oil

1 teaspoon vanilla extract

1 cup semisweet chocolate chips

Pinch of fine salt (optional)

1/2 cup chopped nuts, such as walnuts or pecans (optional)

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 350°F and line a baking sheet with parchment paper or silicone baking mat.

2. In a large bowl whisk the boxed brownie mix, eggs, vegetable oil, and vanilla extract until a thick, glossy dough forms and no dry streaks remain.

3. If using, stir in the pinch of fine salt to enhance flavor.

4. Fold in the semisweet chocolate chips and the chopped nuts if using, distributing evenly through the dough.

5. Scoop dough by rounded tablespoons or using a small cookie scoop, spacing mounds about 2 inches apart on the prepared baking sheet.

6. For fudgier centers, gently press each mound down slightly with the back of a spoon or your fingers.

7. Bake for 8 to 10 minutes, or until edges are set and centers look just slightly underbaked for a chewy, fudgy texture.

8. Remove from oven and let cookies cool on the baking sheet for 5 to 10 minutes to finish setting.

9. Transfer cookies to a wire rack to cool slightly more, then serve warm or at room temperature.

FAQ

Can I use a different size boxed brownie mix? Yes, but size affects liquid and egg ratios. For smaller 10 to 12 ounce mixes reduce eggs to 1 and oil to 2 tablespoons; for larger mixes follow the same proportions listed but expect more cookies and slightly longer bake time.

Can I omit the chocolate chips or nuts? Yes. Omitting chips yields a fudgy chocolate cookie; swap chips for M&M, butterscotch, or dried fruit for variation. Nuts are optional and can be left out for nut free cookies.

How do I know when cookies are done? Edges should be set and slightly cracked while centers remain soft. They will firm as they cool. Bake a minute or two less for chewier texture, a minute or two more for cakier cookies.

Can I make the dough ahead or freeze it? Yes. Chill dough up to 48 hours in an airtight container or freeze shaped dough balls for up to 3 months. Bake from frozen, adding 1 to 2 minutes to baking time.

How should I store leftovers? Store cooled cookies in an airtight container at room temperature for up to 4 days or refrigerate up to 1 week. For longer storage freeze up to 3 months.

Can I make these gluten free? Use a gluten free boxed brownie mix labeled for baking. Texture may vary slightly but results will still be chewy and fudgy.

Chewy & Fudgy Brownie Mix Cookies – So Easy & Delicious! Recipe Substitutions and Variations

Eggs: Substitute each large egg with 1/4 cup unsweetened applesauce for a moist cookie, or 1/4 cup mashed banana for a slightly sweeter, fruitier note; for vegan option use 1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg, let sit 5 minutes to gel.
Vegetable oil: Swap 1:1 with melted coconut oil for a subtle coconut flavor or with neutral-tasting melted butter for richer, more buttery cookies; for lower fat, use 3/4 cup plain Greek yogurt in place of 1 cup oil adjusting bake time slightly shorter.
Vanilla extract: Replace 1 teaspoon with 1 teaspoon almond extract for a nutty twist, or use 1 teaspoon strong brewed espresso for deeper chocolate notes; for alcohol free, use 1 teaspoon vanilla paste or scraped vanilla bean.
Semisweet chocolate chips: Use equal amounts of chopped dark chocolate for a more intense flavor, milk chocolate for creamier sweetness, or white chocolate chips for contrast; to reduce sugar, use 3/4 cup sugar-free chocolate chips keeping total volume the same.

Pro Tips

1. Let the eggs come fully to room temperature before mixing; they help the batter come together into a glossy, cohesive dough and give a nicer texture than cold eggs.

2. Mix just until the batter is smooth and there are no dry streaks. Overmixing can make cookies cakier instead of fudgy, so stop as soon as it looks combined.

3. For thicker, chewier cookies, chill the scooped dough in the fridge for 15 to 30 minutes before baking. If you want flatter, crisper edges, bake right away and press the mounds down a little.

4. Sprinkle a tiny pinch of flaky sea salt on each cookie as they come out of the oven and cool for a minute. That bright pop of salt makes the chocolate taste much richer.
