While I absolutely adore crafting chocolate cookies from scratch, there are those times when nothing beats the sheer convenience of a boxed mix. It’s a fantastic shortcut that streamlines the baking process, cutting down on both ingredients and prep time. Over the years, I’ve successfully transformed a simple box of cake mix into a variety of treats, from delightful cake mix brownies to an assortment of easy cookies. This time, the star of the show is boxed brownie mix, elevated into the most delectable brownie mix cookies you can imagine. These chocolate cookies are a symphony of rich, fudgy texture, generously studded with melty chocolate chips, boasting soft-baked centers and irresistibly crispy edges. With just 4 core ingredients and the magic of a single mixing bowl, baking cookies simply doesn’t get any easier or more satisfying!

What You’ll Need for the Perfect Brownie Cookies

You won’t believe how lusciously fudgy these cookies turn out with such a minimal list of ingredients! It all boils down to just 4 simple items, plus the optional but highly recommended chocolate chips. These are ingredients you likely already have in your pantry, making spontaneous cookie baking a reality. I’ve added a few quick notes on each below, but for the exact measurements, be sure to refer to the comprehensive printable recipe card further down this page.

  • Brownie Mix: The cornerstone of this recipe! You’ll need one standard 18-19 ounce box of your preferred store-bought brownie mix. The beauty of this recipe is that it works wonderfully with any brand you love, whether it’s a fudgy-style mix or one designed for cakier brownies. If you’re feeling ambitious and happen to have some on hand, my homemade brownie mix can also be used for an even more personalized touch.
  • All-Purpose Flour: Just a quarter cup of all-purpose flour is added to the brownie mix. This isn’t to make them cakey, but rather to give the cookies a bit more structure and prevent them from spreading too much in the oven, ensuring those perfectly thick and chewy results we all crave. It helps balance the richness of the brownie mix and creates that ideal cookie texture.
  • Vegetable Oil: A neutral-flavored oil, such as canola or standard vegetable oil, is recommended here. It contributes to the fudgy texture of the cookies without imparting any unwanted flavors. You could also experiment with melted coconut oil (if you like a subtle coconut flavor) or even melted unsalted butter for a richer taste, though vegetable oil consistently delivers excellent results for this recipe.
  • Large Eggs: We’re using two large eggs in this recipe. The addition of an extra egg (compared to what many brownie mix cookie recipes might call for) is key to achieving that wonderfully chewy, almost gooey, texture that makes these cookies so irresistible. Ensure your eggs are at room temperature if possible, as this helps them incorporate more smoothly into the batter.
  • Chocolate Chips: While technically optional, I honestly can’t resist adding an extra half cup of chocolate chips to these already chocolate-packed cookies! They melt into glorious pockets of chocolate, enhancing the fudgy experience. You can use semi-sweet, milk chocolate, dark chocolate, or even white chocolate chips. If you’re looking to branch out, these cookies are also fantastic with other add-ins like chopped nuts (pecans, walnuts), colorful M&Ms, Heath Bar toffee bits, or even mini peanut butter cups.

How to Make Brownie Mix Cookies: Step-by-Step Guide

Crafting this brownie cookie dough is incredibly quick, taking just a few minutes of active prep time. The recipe does call for a crucial chilling period, but trust me, the wait is absolutely worth it for those perfectly shaped, fudgy cookies! Here’s a detailed breakdown of how to transform a simple brownie mix into chewy, chocolatey perfection. For the complete, printable directions and ingredient list, please scroll down to the recipe card.

  • Combine the Ingredients: Start by adding the entire box of brownie mix, the all-purpose flour, vegetable oil, and both eggs into a large mixing bowl. Using a sturdy spoon or a rubber spatula, mix all these ingredients together until they are just combined and no dry streaks of flour or mix remain. Be careful not to overmix; just combine until the dough forms. At this point, gently fold in your chosen add-ins, such as chocolate chips, ensuring they are evenly distributed throughout the rich, dark dough.
  • Chill the Dough Thoroughly: This step is non-negotiable for achieving perfect brownie mix cookies! Once your dough is mixed, cover the bowl with plastic wrap and place it into the refrigerator to chill for at least 30 to 60 minutes. Chilling the dough is crucial because it helps solidify the fats, which in turn prevents the cookies from spreading too much in the oven, resulting in beautifully thick, chewy, and perfectly shaped cookies. Don’t be tempted to skip this vital step, or you might end up with thin, flat cookies.
  • Portion and Bake to Perfection: After the dough has sufficiently chilled, preheat your oven to 375°F (190°C). Line a baking sheet with parchment paper or a silicone baking mat for easy cleanup and to prevent sticking. Scoop out portions of the firm cookie dough, about 1 to 1.5 tablespoons each, and roll them into smooth, tight balls with your hands. Arrange these dough balls onto the prepared baking sheet, leaving about 2 inches of space between each to allow for spreading. Bake for 9-11 minutes. You’ll know they’re ready when the edges are set and lightly crisp, and the tops begin to crack and look somewhat dry, though the centers will still appear very soft and slightly underdone.
  • Cool for Optimal Texture: Once baked, remove the cookies from the oven and let them cool on the baking sheet for at least 5 minutes. This crucial cooling time allows the cookies to continue setting and firming up without overbaking. After 5 minutes, carefully transfer them to a wire rack to cool completely. This ensures they develop that irresistible fudgy, chewy interior and slightly crispy exterior.

Recipe Tips and Variations for Customizing Your Cookies

These brownie mix cookies are fantastic as is, but a few key tips and creative variations can elevate them even further. Here are some pointers to ensure your cookies are nothing short of perfect every time, along with ideas for customizing them to suit any craving:

  • Always Chill Your Dough to Prevent Overspreading: This is arguably the most important tip for achieving thick, chewy, and perfectly formed cookies. The cookie dough absolutely must be cold and firm directly from the fridge when it goes into the hot oven. If the dough is too warm, the butter or oil will melt too quickly, causing the cookies to spread out excessively and become thin and crispy rather than fudgy and chewy. Shape the dough into tight, uniform balls for the best results.
  • Handling Brownie Mix Syrup Packets: Some brands of brownie mix come with a small packet of chocolate syrup or extra chocolate chunks. For this specific cookie recipe, you won’t need the syrup packet for the dough itself. You can either discard it or, even better, save it to drizzle over your baked and cooled cookies for an extra decadent touch! The solid chocolate chunks, however, can be added directly into the dough along with any other mix-ins.
  • Explore a World of Add-Ins: The versatility of these cookies is one of their best features! Don’t limit yourself to just chocolate chips. Get creative with your flavor combinations:
    • Nuts: Stir in chopped pecans, walnuts, or even toasted almonds for a delightful crunch and nutty flavor.
    • Different Chocolates: Experiment with white chocolate chips, milk chocolate chunks, or dark chocolate morsels for varied sweetness and intensity.
    • Candies & Toffee: Add colorful M&Ms, Reese’s Pieces, butterscotch chips, or crushed Heath Bar toffee bits for extra texture and flavor bursts.
    • Mint: A handful of chopped Andes Mints or mint chocolate chips can transform these into a refreshing chocolate mint cookie.
    • Peanut Butter: Swirl in a tablespoon or two of peanut butter during mixing for a rich chocolate peanut butter cookie, or add peanut butter chips.
  • Don’t Overbake: For the fudgiest texture, err on the side of slightly underbaking. The cookies will continue to cook slightly from residual heat as they cool on the baking sheet. They should look set around the edges but still soft and slightly puffy in the center with visible cracks on top.
  • Consider a Touch of Sea Salt: A tiny sprinkle of flaky sea salt on top of the warm cookies just after they come out of the oven can dramatically enhance the chocolate flavor and add a sophisticated touch.
  • Prepare Your Baking Sheets: Always use parchment paper or silicone baking mats. This not only prevents sticking but also promotes even baking and easy cleanup.

How to Store Your Brownie Mix Cookies

Once you’ve baked a batch of these irresistible brownie mix cookies, you’ll want to ensure they stay fresh and delicious for as long as possible. Proper storage is key to maintaining their soft, fudgy texture. Here’s how to store them for both short-term enjoyment and long-term convenience:

  • Storing on the Counter (Room Temperature): To keep your baked brownie cookies fresh and moist, store them in an airtight container at room temperature. They will remain wonderfully delicious for up to 4 days. Placing a slice of bread in the container with the cookies can sometimes help keep them even softer by sharing its moisture.
  • Freezing Baked Brownie Mix Cookies: For longer storage, these cookies freeze beautifully. Once completely cooled, arrange them in a single layer on a baking sheet and freeze until solid (about 1-2 hours). Then, transfer the frozen cookies to an airtight freezer-safe container or a heavy-duty freezer bag. They can be stored for up to 1 month. When you’re ready to enjoy them, simply thaw the cookies at room temperature for a few hours, or gently warm them in the microwave for a few seconds for that freshly baked feel.
  • Freezing Unbaked Cookie Dough: You can also prepare the cookie dough ahead of time and freeze it for future baking. After chilling the dough, scoop and roll it into individual balls as directed. Place the dough balls on a parchment-lined baking sheet and freeze until solid. Once frozen, transfer the dough balls to an airtight freezer-safe bag or container. They can be stored for up to 2-3 months. When ready to bake, you can bake them directly from frozen, adding an extra 2-4 minutes to the baking time, or let them thaw slightly in the refrigerator for an hour before baking. This is a fantastic way to always have freshly baked cookies on demand!

Ingredients 

  • 1 18-19 ounce box of brownie mix
  • ¼ cup all-purpose flour
  • ¼ cup vegetable oil
  • 2 large eggs
  • ½ cup chocolate chips (plus more for topping, optional)

Instructions 

  • In a large mixing bowl, combine the brownie mix, all-purpose flour, vegetable oil, and two large eggs.

Gently fold in the chocolate chips until they are evenly distributed throughout the dough.

  • Cover the bowl with plastic wrap and chill the cookie dough in the refrigerator for at least 30 to 60 minutes. This step is crucial to prevent the cookies from spreading too much during baking, ensuring a thick and chewy result.
  • Preheat your oven to 375ºF (190ºC). Line a baking sheet with parchment paper or a silicone baking mat.
  • Scoop the chilled dough into 1 to 1.5 tablespoon-sized balls. Roll them gently between your palms to form smooth, tight spheres. Place the dough balls onto the prepared baking sheet, leaving about 2 inches of space between each cookie to allow for spreading.
  • Bake for 9-11 minutes, or until the edges are set and lightly crisp, and the tops begin to crack and appear slightly dry, even if the centers still look very soft and a bit underdone. Remove the baking sheet from the oven and let the cookies cool on the sheet for 5 minutes before carefully transferring them to a wire rack to cool completely. This helps them firm up and achieve the perfect fudgy texture.

Notes

  • For the best thick and chewy cookies, always ensure your cookie dough is cold when it goes into the oven. This prevents excessive spreading.
  • Chocolate chips are a delicious addition, but feel free to customize! Other excellent add-ins include chopped nuts (pecans, walnuts), white chocolate chips, butterscotch chips, or colorful candies like M&M’s or Reese’s Pieces.
  • If your brownie mix comes with a chocolate syrup packet, save it for drizzling over the baked cookies or discard it, as it’s not needed for the cookie dough.
