Description
Transform a simple box of brownie mix into decadent, thick cookies featuring a fudgy center and crisp, crackly edges. These chocolate-loaded treats are incredibly easy to whip up and perfect for satisfying intense cravings in under twenty minutes.
Ingredients
- 1 (18-ounce) box brownie mix (such as Ghirardelli)
- 1/2 cup all-purpose flour
- 2 large eggs
- 5 tablespoons vegetable oil
- 2 tablespoons water
- 1/2 cup mini chocolate chips
- 3/4 cup chopped walnuts (optional)
Instructions
- Preheat your oven to 350°F and line a large baking sheet with parchment paper.
- In a large bowl or stand mixer with a paddle attachment, combine the brownie mix, flour, eggs, oil, water, and mix-ins until a thick, sticky dough forms.
- Use a cookie scoop to drop rounded tablespoons of dough onto the prepared baking sheet, spacing them 2 inches apart.
- Bake for 8 to 10 minutes until a thin film forms on top and the batter is no longer glossy.
- Let the cookies cool on the pan for 2 minutes before transferring them to a wire rack to cool completely.
Notes
For the best texture, ensure you do not overbake these cookies; they should still look slightly soft when removed from the oven as they will firm up while cooling. These cookies can be stored in an airtight container for up to 3 days to maintain their fudgy center.

The Candy Arsenal: What You’ll Need\n\nTo make these massive brownie cookies, you only need a handful of ingredients. The star of the show is an 18-ounce box of Ghirardelli Double Chocolate Brownie Mix. Trust me, starting with a premium box mix is the secret to getting that intense, ridiculous chocolate flavor.\n\n* Brownie Mix: Go for an 18-ounce box. Ghirardelli or Duncan Hines works best for that epic fudgy center.\n* All-Purpose Flour: Just a half cup to give the dough that thick, scoopable cookie structure.\n* Eggs & Oil: Two large eggs and 5 tablespoons of vegetable oil bring the rich, chewy magic.\n* Mini Chocolate Chips: A half cup, because more is absolutely more when it comes to chocolate!\n* Chopped Walnuts: Optional, but tossing in 3/4 cup adds a killer crunch to contrast the gooey center.
Monster Steps: How to Make It\n\n### Step 1: Prep Your Cookie Station\nPreheat your oven to 350°F and line a large baking sheet with parchment paper. You want a non-stick surface so these fudgy monsters slide right off.\n\n### Step 2: Mix the Sticky Dough\nIn a large bowl or stand mixer fitted with a paddle attachment, dump in the brownie mix, flour, eggs, oil, water, and mix-ins. Beat it together until fully combined. The dough will be super thick and wildly sticky—that is exactly what you want!\n\n### Step 3: Scoop and Space\nUse a small cookie scoop to drop the dough onto your prepared baking sheet, keeping them about 2 inches apart. If you want giant, NYC-style bakery cookies, use a medium scoop, but remember to add 1 to 2 extra minutes to your bake time.\n\n### Step 4: Bake to Fudgy Perfection\nBake for 8 minutes to start. Look for a thin film on top; the batter should not be glossy anymore but you might see small ripples of dark batter. Do not overbake! They cook fast and will keep setting up on the hot pan.\n\n### Step 5: Cool and Devour\nPull them from the oven and let them chill on the pan for a couple of minutes. Transfer these loaded beauties to a cooling rack and eat them warm while the chocolate is still oozing!
Riley’s Wild Tips for Brownie Cookies\n\nThe absolute most important rule here: watch your baking time like a hawk! These cookies are a little temperamental. One extra minute can steal that gooey, fudgy center we crave. In my gas oven, 8 minutes is the sweet spot, but electric ovens might need 9 or 10 minutes. Always bake a test cookie first to nail down your exact timing!\n\nAlso, do not try to mix this beast of a dough with a whisk! The batter is incredibly thick and sticky, so a paddle attachment or a sturdy wooden spoon is your best friend. For more brilliant shortcuts, check out my quick cookie solutions.

Mashup Ideas: Go Even Bigger\n\nWho says you have to stop at mini chocolate chips? We are all about breaking the rules! Stuff a mini Reese’s cup or a chunk of Snickers right into the center of the dough ball before baking. When you bite in, the candy will ooze out and absolutely blow your mind.\n\nYou can also swap the walnuts for M&Ms, crushed Oreos, or white chocolate chips for a massive color explosion! If you love playing around with simple bases, try turning these into a sandwich cookie with peanut butter frosting. For another wild twist, check out how we load up our classic cake mix gingerbread to make them epic!
Party Mode: How to Serve\n\nThese massive, loaded brownie cookies demand attention! Serve them warm right out of the oven so the chocolate chips are visibly oozing when you break them apart. Stack them high on a sharing platter and watch your friends completely lose their minds.\n\nFor an over-the-top dessert, smash a warm cookie into the bottom of a bowl and drown it in vanilla bean ice cream and hot fudge! If you are building an epic dessert table for a party, pair these alongside our insane cookies and cream cookies to really bring the house down!
