Ingredients for Easy Brownie Mix Cookies

This basic recipe starts with a standard box of brownie mix and a handful of everyday ingredients, making it easy to throw together at any time.

  • 1 (19.8 ounce) package brownie mix (any brand or flavor)
  • 1/4 cup all-purpose flour
  • 1/4 cup vegetable oil
  • 2 large eggs
  • 3 tablespoons water
  • 1 cup semisweet chocolate chips (optional for extra chocolatey goodness)

Step-by-Step Directions

  1. Preheat the oven: Set your oven to 350°F (175°C). Line baking sheets with parchment paper or lightly grease them for easy removal.
  2. Mix dry ingredients: In a large bowl, combine the brownie mix and all-purpose flour. Stir until evenly blended.
  3. Add wet ingredients: Add the vegetable oil, eggs, and water to the dry mixture. Stir until a thick, even dough forms. Avoid overmixing for the best cookie texture.
  4. Stir in extras: If desired, add the chocolate chips and gently fold them into the dough for extra flavor and texture.
  5. Scoop dough: Drop dough by rounded tablespoonfuls onto your prepared baking sheets. Leave at least 2 inches of space between cookies to allow for spreading.
  6. Bake: Bake in preheated oven for 8–10 minutes, or until set around the edges but still soft in the center. Avoid overbaking to keep them chewy.
  7. Cool: Let cookies cool on the baking sheet for 2–3 minutes, then transfer to wire racks to cool completely.

Expert Tips for Brownie Mix Cookie Success

  • Choose your favorite brownie mix: Classic chocolate, dark chocolate, or even flavored varieties (like mint or caramel swirl) all work well.
  • Don’t overbake: Brownie mix cookies are best when soft and chewy. Remove them from the oven when the edges are set but the centers still look slightly underdone—the residual heat will finish baking them.
  • Customize with mix-ins: In addition to chocolate chips, try chopped nuts, peanut butter chips, or white chocolate chips. Swirl in a little peanut butter or caramel before baking for a gourmet twist.
  • Uniform size: Use a cookie scoop for even, consistent sizing, which helps with even baking.
  • Storage: Store cooled cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze cookies between layers of wax paper for up to 2 months.

Possible Variations and Add-Ins

  • Nutty Brownie Cookies: Add 3/4 cup of chopped walnuts or pecans to the batter before baking.
  • Double Chocolate: Use dark chocolate chips or chunks for even more intense chocolate flavor.
  • Salted Caramel: Press a caramel candy into the center of each dough ball before baking, and sprinkle lightly with sea salt when warm.
  • Peanut Butter Swirl: Drop small dollops of creamy peanut butter onto each cookie before baking and swirl gently with a toothpick.
  • Holiday Treat: Roll dough balls in colored sprinkles or crushed peppermint candies before baking for festive flair.
  • Brookie Cookies: Combine half cookie dough and half brownie mix dough for a “brookie” mashup.

Baking Tips and Troubleshooting

  • Why are my cookies spreading too much? If cookies turn out flat, too much oil or insufficient flour may be the cause. Make sure to measure ingredients carefully and consider chilling the dough slightly if your kitchen is warm.
  • Why are my cookies too cakey? Overmixing the dough or using more eggs than called for can create a cakier result. For chewier cookies, stir just until combined and stick to the recommended egg amount.
  • How to fix dry dough? If your cookie dough seems dry or crumbly, add a tablespoon of water at a time, mixing gently until the dough comes together.
  • Sticky dough? Lightly grease your hands or use a cookie scoop sprayed with nonstick spray to handle sticky dough with ease.

Frequently Asked Questions (FAQs)

Can I use any type of brownie mix?

Yes! While the classic fudge brownie mix is most common, you can use your favorite box brand or flavor—such as dark chocolate, gluten-free, or even flavors with swirls or mix-ins. Adjust liquid amounts as needed if your mix weight is different.

Can I make these cookies dairy-free or gluten-free?

Yes. Choose a gluten-free brownie mix and substitute with a gluten-free flour blend. For dairy-free, ensure your brownie mix and chocolate chips do not contain milk ingredients.

My cookies are dry or crumbly. What did I do wrong?

Dry cookies can result from overbaking or using too much flour. Check your measurements and baking time, and try reducing flour slightly if needed.

Can I freeze the dough or baked cookies?

Absolutely. Freeze unbaked dough balls on a baking sheet, then transfer to a freezer bag. Bake directly from frozen, adding 1–2 minutes to bake time. Baked cookies can be frozen for up to 2 months—just thaw at room temperature before enjoying.

How should I store leftover cookies?

Store cooled cookies in a tightly sealed container at room temperature for up to 5 days. Add a slice of bread to the container to help keep cookies extra soft.
