Brownie Mix Cookies – Chewy, Fudgy, and Easy to Make!

If you love chewy brownies and soft cookies, then these Brownie Mix Cookies are the perfect treat! With just a few simple ingredients, you can turn a box of brownie mix into thick, fudgy cookies that taste like a cross between a brownie and a cookie.

They’re quick, easy, and require only one bowl—making them perfect for last-minute dessert cravings, bake sales, or holiday cookie platters.

Ingredients

• 1 box (18-20 oz) brownie mix
• 2 large eggs
• ⅓ cup vegetable oil (or melted butter for a richer taste)
• 2 tablespoons all-purpose flour
• 1 teaspoon vanilla extract (optional, but adds great flavor)
• ½ cup chocolate chips or chunks (optional, for extra chocolatey goodness)

Instructions

Step 1: Preheat the Oven

• Preheat your oven to 350°F (175°C).
• Line a baking sheet with parchment paper or lightly grease it.

Step 2: Make the Dough

1. In a large mixing bowl, combine the brownie mix, eggs, oil, flour, and vanilla extract.
2. Stir until the dough comes together—it will be thicker than brownie batter but softer than traditional cookie dough.
3. Gently fold in the chocolate chips (if using).

Step 3: Scoop & Shape the Cookies

4. Use a cookie scoop or spoon to drop tablespoon-sized dough balls onto the prepared baking sheet.
5. Space them 2 inches apart, as they will spread slightly.

Step 4: Bake the Cookies

6. Bake for 9-12 minutes, or until the edges are set but the centers are slightly soft.
7. Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

Notes

• For extra fudgy cookies, slightly underbake them and let them firm up as they cool.
• For crispier edges, bake for an extra 1-2 minutes.
• Chill the dough for 20 minutes before baking if you want thicker cookies.

Helpful Tips for the Best Brownie Mix Cookies

1. Chill the Dough for Thicker Cookies

• If your dough feels too soft or sticky, chill it for 20-30 minutes before baking.
• This helps prevent spreading and makes chewier, thicker cookies.

2. Don’t Overbake – They Will Continue to Set!

• Cookies should look slightly underbaked in the center when you take them out.
• Let them cool on the baking sheet for 5 minutes before transferring them to a rack—they will firm up as they cool.

3. Use Butter Instead of Oil for Richer Flavor

• Swap vegetable oil for melted butter to get a richer, more homemade taste.

4. Add Extra Chocolate for More Fudginess

• Mix in chocolate chips, chopped chocolate, or cocoa nibs for a double chocolate cookie.

5. Space Cookies Properly on the Baking Sheet

• These cookies spread slightly, so leave at least 2 inches between each cookie.

6. Experiment with Different Mixes

• Use dark chocolate, salted caramel, or triple chocolate brownie mix for different flavors.

7. Make Stuffed Cookies for an Extra Treat

• Flatten a dough ball and place a piece of chocolate, peanut butter cup, or marshmallow inside before sealing and baking.

8. Turn Them Into Brownie Crinkle Cookies

• Roll dough balls in powdered sugar before baking to create a crackly, crinkle-top effect.

9. Store Properly for Freshness

• Keep at room temperature in an airtight container for up to 5 days.
• Freeze dough balls and bake from frozen for fresh cookies anytime!

10. Reheat for a Fresh-Baked Taste

• Warm cookies in the microwave for 10-15 seconds to make them soft and gooey again.
