How to Make Loaded Brownie Mix Cookies Recipe
Step 1: Preheat and Prepare Your Baking Sheet
Get your oven warmed to 350°F (175°C) and line a baking sheet with parchment paper. This simple step ensures non-stick baking and easy cleanup, setting the stage for cookie perfection.
Step 2: Mix the Dry Ingredients
In a large bowl, whisk together your brownie mix, flour, and salt. This combination forms the foundation of your cookie dough, making sure every bite has that rich, chocolaty essence you crave.
Step 3: Add the Wet Ingredients
Pour in the vegetable oil, crack in the eggs, and add the vanilla extract. Stir everything until the batter is uniform and smooth. This step brings your dough to life, promising a tender yet chewy texture after baking.
Step 4: Fold in the Fun Mix-Ins
Gently fold in chocolate chips, chopped walnuts, and if you’re feeling adventurous, those colorful M&Ms or gooey mini marshmallows. These loaded mix-ins elevate the cookie experience, adding bursts of texture and flavor that surprise and delight with every bite.
Step 5: Scoop and Bake the Cookies
Use a spoon or cookie scoop to place dollops of dough about 2 inches apart on your prepared baking sheet. Bake them for 8-10 minutes, watching closely until the edges get set but the centers remain soft and inviting—this balance creates the ultimate chewy-fudgy texture.
Step 6: Cool and Enjoy
Allow the cookies to rest on the baking sheet for a few minutes before transferring to a wire rack. This resting period lets them firm up just enough without losing their gooey charm, making every bite pure bliss.
How to Serve Loaded Brownie Mix Cookies Recipe

Garnishes
Sprinkle a pinch of flaky sea salt on top just as the cookies come out of the oven for a sophisticated contrast that makes the chocolate sing. Alternatively, drizzle melted white or dark chocolate over the cooled cookies for an elegant finish that’s perfect for gifting.
Side Dishes
Pair these loaded treats with a cold glass of milk or a steaming cup of coffee to balance the richness. For a fun twist, serve alongside a scoop of vanilla ice cream for an indulgent dessert that’s sure to impress any crowd.
Creative Ways to Present
Arrange them on a festive platter with extra nuts and candies sprinkled around for a vibrant look. Or sandwich two cookies with a layer of frosting or peanut butter inside for a delightful cookie sandwich that takes this recipe to the next level of yum.
Make Ahead and Storage
Storing Leftovers
Keep your leftover cookies fresh by storing them in an airtight container at room temperature. They’ll maintain their chewy texture for up to 4 days, making them perfect for snacking or last-minute dessert cravings.
Freezing
If you want to enjoy these cookies later, freeze unbaked dough balls separated on a baking sheet, then transfer them to a freezer bag once solid. You can bake straight from frozen, adding a couple of extra minutes to the bake time, so you always have homemade goodness on hand.
Reheating
To refresh your cookies, warm them briefly in the microwave for about 10-15 seconds or pop them in a low oven for a few minutes. This revives that fresh-baked softness and gooey chocolate that makes them irresistible every time.

What if I’m allergic to nuts?
Feel free to omit the walnuts or replace them with seeds like sunflower or pumpkin seeds for a nut-free crunch, or simply increase the chocolate chips and marshmallows for extra indulgence.

With some simple swaps such as flax eggs or a vegan egg replacer and dairy-free chocolate chips, you can adapt this recipe to suit vegan or dairy-free diets while still keeping all the indulgent flavors.

They strike the perfect balance of chewy and fudgy, with slightly crisp edges and soft, gooey centers that melt in your mouth. Timing your bake just right is the secret to this delightful texture.
