Prep & Cook Time
Prep Time: 10 minutes
Cook Time: 40 minutes
Total Time: 50 minutes
Servings: 20 cookies
Ingredients
- 1 box brownie mix (fudge variety)
- 2 Tablespoons all-purpose flour
- 2 large eggs (whisked)
- ⅓ cup vegetable oil
- 1 box yellow cake mix (13.25 oz. box)
- 2 Tablespoon flour
- 2 large eggs (whisked)
- ½ cup vegetable oil
- 1 cup mini chocolate chips
Instructions
- Preheat your oven to 350°F (175°C). Line two large baking sheets with parchment paper.
- In a medium bowl, prepare the brownie dough. Combine the box of brownie mix, 2 Tablespoons of flour, 2 whisked eggs, and ⅓ cup vegetable oil. Stir until just combined and a thick dough forms. Set aside.
- In a separate large bowl, prepare the cookie dough. Combine the box of yellow cake mix, 2 Tablespoons of flour, 2 whisked eggs, and ½ cup vegetable oil. Stir until a soft dough forms. Fold in the 1 cup of mini chocolate chips until evenly distributed.
- Using a medium cookie scoop or two spoons, drop alternating scoops of the brownie dough and the cookie dough onto the prepared baking sheets, placing them about 2 inches apart. Aim for 20 portions total.
- Bake for 10-12 minutes, or until the cookie edges are lightly golden and the centers look just set. The cookies will continue to firm up as they cool.
- Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.
Variations
- Cookie Sandwich: Once cooled, sandwich two cookies together with a scoop of vanilla ice cream for an ultimate brookie ice cream sandwich.
- Skillet Brookie: Press all the marbled dough into a greased cast-iron skillet and bake at 350°F for 25-30 minutes for a shareable brookie skillet cookie.
- Stuffed Cookie: Take a scoop of the brownie dough, flatten it, place a small ball of the cookie dough in the center, and wrap the brownie dough around it before baking for a hidden center.
- Bar Form: Press the marbled dough into a greased 9×13-inch pan and bake at 350°F for 20-25 minutes, then cut into squares for easy brookie bars.
Tips for Success
- For the best marbled look, only swirl the doughs 2-3 times on the baking sheet. Over-mixing will result in a uniform, single-color cookie.
- Use a cookie scoop for evenly sized cookies, which ensures they bake at the same rate.
- Let the cookies cool on the baking sheet—they are very soft when hot and will break if moved too soon.
- If your dough seems too sticky to handle, chill it in the refrigerator for 15-20 minutes before scooping.
Storage & Reheating
Store completely cooled cookies in an airtight container at room temperature for up to 4 days. For longer storage, freeze them in a single layer on a baking sheet before transferring to a freezer bag for up to 3 months. To reheat, microwave a cookie for 10-15 seconds or warm in a 300°F oven for 3-5 minutes.
FAQ
Can I use a different flavor of cake or brownie mix?
Yes, you can experiment. A chocolate cake mix will make a double-chocolate cookie, while a blondie mix can be used in place of the brownie mix for a different flavor profile.
Why do I need to add extra flour to the box mixes?
The added flour helps thicken the batters into a scoopable dough suitable for cookies, preventing them from spreading too thin.
My cookies spread a lot. What happened?
This is likely due to the dough being too warm or the oven temperature being off. Ensure your ingredients are at room temperature (not warm) and use an oven thermometer to verify the correct temperature.
Can I make one big batch of dough instead of two separate ones?
No, the two doughs have different ratios of wet to dry ingredients. Mixing all the ingredients together will not create the distinct brownie and cookie textures and will likely result in baking issues.
Can I use melted butter instead of oil?
For this specific recipe, stick with vegetable oil as listed. The box mixes are formulated for oil, and butter has a different water content which can affect the texture and spread.
Can I add nuts or other mix-ins?
Absolutely! While the recipe uses mini chocolate chips, you could substitute or add chopped walnuts, pecans, or even toffee bits to the cookie dough portion for extra crunch and flavor.
