How to Make Loaded Brownie Mix Cookies Recipe
Step 1: Prep Your Oven and Baking Sheet
Start by preheating your oven to 350°F (175°C) and lining a baking sheet with parchment paper. This simple step ensures your cookies bake evenly, and the parchment paper prevents sticking, making cleanup a breeze.
Step 2: Mix the Dry Ingredients
In a large bowl, combine the brownie mix, all-purpose flour, and salt. This blend is the foundation for your cookie dough, balancing sweetness and structure for the perfect bite.
Step 3: Add the Wet Ingredients
Pour in the vegetable oil, eggs, and vanilla extract, then stir everything together until fully combined. The mixture will be thick and glossy, primed for those delicious mix-ins that make this cookie so loaded.
Step 4: Fold in Your Mix-Ins
It’s time to add the chocolate chips, chopped walnuts, and your choice of colorful M&Ms or mini marshmallows. Gently fold them into the dough to evenly distribute all those delightful flavors and textures.
Step 5: Scoop and Bake
Use a spoon or cookie scoop to drop dough balls onto the prepared baking sheet, spacing them about 2 inches apart. This spacing gives the cookies room to gently spread, creating just the right shape and thickness.
Step 6: Bake to Perfection
Bake the cookies for 8-10 minutes. You’ll know they’re ready when the edges look set while the centers still appear soft—this ensures that signature chewy brownie texture inside each cookie.
Step 7: Cool and Enjoy
Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack. Cooling helps them firm up slightly without losing that decadent softness you want in every bite.
How to Serve Loaded Brownie Mix Cookies Recipe

Garnishes
To elevate your Loaded Brownie Mix Cookies Recipe, sprinkle a pinch of flaky sea salt on top right after baking. The contrast of salty and sweet is heavenly and enhances the chocolate’s richness. For extra indulgence, drizzle melted white or dark chocolate over the cookies just before serving.
Side Dishes
These cookies pair beautifully with a simple glass of cold milk or a scoop of vanilla ice cream. For a grown-up twist, try serving them alongside a rich espresso or your favorite nutty liqueur to complement their deep chocolatey notes.
Creative Ways to Present
Make cookie sandwiches by spreading creamy peanut butter or marshmallow fluff between two cookies. Or arrange them on a festive platter garnished with fresh berries and mint leaves for a show-stopping dessert at your next gathering.
Make Ahead and Storage
Storing Leftovers
Keep any leftover cookies fresh by storing them in an airtight container at room temperature. They’ll stay soft and chocolaty for up to 3-4 days, perfect for a quick treat throughout the week.
Freezing
If you want to enjoy these cookies later, freeze individual baked cookies in a single layer on a baking sheet, then transfer them to a freezer bag. They freeze beautifully for up to 2 months without losing their charm.
Reheating
For that freshly-baked feel, pop frozen or stored cookies in the microwave for 10-15 seconds or warm them in a low oven (300°F) for about 5 minutes. This brings back that melty, gooey goodness you love.
FAQs
Can I use any brownie mix for this recipe?
Absolutely! Whether it’s fudgy, double chocolate, or even gluten-free brownie mix, feel free to use your favorite brand. Just keep in mind that variations might slightly affect texture but never the delicious flavor.
What can I substitute for walnuts if I have a nut allergy?
You can swap walnuts for seeds like pumpkin or sunflower seeds for crunch, or simply leave out nuts altogether. The cookies will still taste amazing with all the chocolate and other add-ins.
Is it possible to make these cookies vegan?
With a few tweaks, yes! Use a plant-based brownie mix, substitute eggs with flaxseed or chia seed egg replacer, and swap vegetable oil for coconut oil. The cookies will be just as indulgent and satisfying.
Why do you add flour to the brownie mix?
Adding flour helps provide extra structure and chewiness to the cookies, preventing them from spreading too much while keeping that perfect brownie-like texture.
Can I add other mix-ins besides chocolate chips and nuts?
Definitely! Feel free to mix in dried fruit, toffee bits, shredded coconut, or any other favorite treats. The Loaded Brownie Mix Cookies Recipe is very versatile and encourages your creativity.
