Brownies Mix Cookies: The Easiest Way to Make Fudgy, Crinkle-Topped Treats

If you love chewy, chocolatey desserts that come together in minutes, then Brownies Mix Cookies are about to become your new go-to treat. These quick cookies use a store-bought brownie mix to deliver the best of both worlds: the iconic crinkly tops of brownies and the chewy, bite-sized format of cookies. Whether you’re baking for a party or craving something sweet after dinner, this recipe makes dessert nearly effortless.

While cookies from scratch are great, using a brownie mix saves time and ensures you get that signature fudgy center.

What Are Brownies Mix Cookies?

Essentially, brownies mix cookies are cookies made by adapting a boxed brownie mix. Instead of following the instructions on the box, you tweak the ingredients to create a thicker, dough-like batter that holds its shape during baking. The result is a cookie with a crackly exterior and a soft, gooey center.

This baking hack is loved by home bakers everywhere because:

• It’s faster than baking cookies from scratch

• It requires fewer ingredients

• It produces consistently great results

Plus, you can mix things up with fun flavors like peanut butter, mint, or nuts — and you won’t need fancy kitchen gear.

Ingredients for Classic Brownies Mix Cookies

Here’s what you’ll need:

• 1 (20 oz) box of brownie mix (dry mix only – do not follow box instructions)

• ¼ cup all-purpose flour – helps form a dough-like texture

• ¼ cup vegetable oil – provides moisture like in traditional brownies

• 2 large eggs – acts as a binder and adds richness

• ½ cup chocolate chips – optional, but great for added texture

Clean Ingredient Notes:

• No alcohol: use alcohol-free vanilla if desired

• No pork or gelatin: there are zero animal-based thickeners here

• Suitable for halal and vegetarian diets

How to Make Brownies Mix Cookies (Step-by-Step)

1. Preheat your oven to 375°F and line a baking sheet with parchment paper.

2. In a large bowl, combine the dry brownie mix, flour, eggs, vegetable oil, and chocolate chips.

3. Mix until fully combined using a hand mixer or wooden spoon. The dough will be thick and sticky.

4. Scoop cookie dough using a 2-tablespoon cookie scoop. Place dough balls 2 inches apart.

5. Bake for 8–10 minutes. The edges should look set while the centers still appear slightly doughy.

6. Rest on the pan for 3 minutes, then transfer to a wire rack to cool completely.

Pro Tip: Don’t overbake! The gooey center is the best part.

Why This Recipe Works Every Time

There are several reasons this simple recipe consistently delivers delicious results:

• Added flour gives the mix structure for cookie form

• Oil instead of butter keeps the texture moist and fudgy

• Eggs add stability and richness

• Chocolate chips enhance that brownie flavor and offer melty goodness

Recipe Tips and Tricks

To truly master this recipe, keep the following tips in mind:

✅ Use a 20 oz brownie mix. If your box is smaller, add enough flour to compensate.

✅ For extra fudginess, slightly underbake the cookies.

✅ Always let cookies rest for a few minutes after baking before moving to a rack.

Frequently Asked Questions (FAQs) About Brownies Mix Cookies

Got questions about baking with brownie mix? You’re not alone! Below are answers to the most common queries home bakers have about making Brownies Mix Cookies — whether it’s about texture, ingredient swaps, or baking technique.

Can you make cookies with brownie mix?

Absolutely, yes! Brownie mix isn’t just for brownies — with a few tweaks, it can be transformed into fudgy, chewy cookies that are every bit as indulgent. Instead of following the box directions, you’ll mix in:

• Eggs for richness and binding

• Vegetable oil to mimic traditional brownie moisture

• Flour to give the dough structure and prevent spreading

The result is a cookie that’s part brownie, part chocolate heaven, and all kinds of delicious.

Why are my brownie mix cookies dry?

Dry cookies usually mean one of two things: either they were overbaked or your brownie mix was too small and not properly adjusted.

• Overbaking: Brownie cookies should be pulled from the oven when the edges are set but the centers still look soft or doughy. Residual heat will finish baking them on the sheet.

• Box size error: Most recipes are designed for a 20 oz brownie mix. If your mix is smaller (many are 18.3 oz or 18 oz), the ratio of wet to dry will be off — resulting in a dry, crumbly texture.

Tip: Always check the mix weight and adjust by adding enough flour to equal 20 oz total, then follow the rest of the recipe as directed.

Can I add peanut butter or nuts to the batter?

Yes, and it’s highly recommended if you want to level up the flavor! Add-ins are a fun and easy way to customize your Brownies Mix Cookies:

• Peanut butter chips for creamy bursts of nutty flavor

• Chopped walnuts or pecans for crunch

• Mini M&Ms or caramel bits for something sweet and playful

• A swirl of peanut butter or Nutella for a rich, gooey core

Mix them directly into the dough or press a few into the tops of the cookies before baking for an extra visual pop.

What if my brownie mix is less than 20 oz?

That’s a great question — and a common situation!

Many boxed brownie mixes on the market come in 18.3 oz or smaller, but cookie recipes usually assume a full 20 oz. To fix this:

1. Weigh your dry mix using a kitchen scale

2. Add enough all-purpose flour to bring it up to 20 oz total

3. Then, add the additional ¼ cup of flour the recipe calls for — this extra bit is still needed to create cookie dough texture

Pro tip: Skipping this step leads to cookies that spread too thin and lack structure.

Can I make Brownies Mix Cookies without eggs?

Yes, but you’ll need a reliable egg substitute. If you’re baking for someone with an egg allergy, or if you follow a plant-based diet, try one of the following:

• Flax eggs – Mix 1 tablespoon ground flaxseed with 3 tablespoons water per egg. Let sit for 5 minutes to gel.

• Chia eggs – Same method as flax, using chia seeds

• Commercial egg replacers – Follow package directions

• Unsweetened applesauce – Use ¼ cup per egg for a softer cookie

Keep in mind: Egg-free cookies may be slightly softer or less chewy, but they still taste great!

Bonus FAQ: Do I need to chill the dough before baking?

No chilling required! One of the major benefits of using brownie mix cookies is that they’re fast and no-fuss. The dough is slightly sticky but firm enough to portion and bake immediately.

However, if your kitchen is very warm or the dough seems too soft to hold shape, a 10-minute chill can help reduce spreading.

Can I use gluten-free brownie mix?

Yes! Many brands now offer gluten-free brownie mixes that work beautifully for cookies too. Just make sure to:

• Follow the same flour adjustment (up to 20 oz dry mix)

• Add the ¼ cup additional flour — use gluten-free all-purpose flour

• Double-check the label for other allergens or fillers

Tip: Gluten-free versions may bake a bit faster or have slightly different textures — so keep an eye on them in the oven!

Common Mistakes to Avoid When Making Brownies Mix Cookies

Even though Brownies Mix Cookies are incredibly simple to make, a few small missteps can keep your cookies from reaching that perfect crackly top, fudgy center, and soft texture. To help you get flawless results every time, here’s a deeper look at the most common baking mistakes — and how to avoid them like a pro.

Following the Instructions on the Brownie Box

Why it’s a problem:
Brownie mix cookie recipes require only the dry brownie mix, not the eggs, water, or oil listed on the box. Those are meant for traditional brownies, not cookies.

What to do instead:
Ignore the back of the box. Follow the custom cookie recipe and add your own specific ingredients — usually flour, eggs, oil, and chocolate chips — to achieve the ideal cookie dough consistency.

Tip: You’re transforming brownie batter into cookie dough — it needs structure, not pourability.

Using Margarine Instead of Oil

Why it’s a problem:
Margarine behaves differently in baking and often results in a greasier, less chewy texture. The fat content and water levels don’t match those in traditional brownies.

What to use:
Stick with vegetable oil, canola oil, or a neutral-tasting sunflower oil. These oils mimic the fats used in boxed brownies, contributing to that soft, moist bite we love.

Skipping the Flour Adjustment

Why it’s a problem:
Boxed brownie mixes are designed to make batter — not dough. Without additional flour, your cookies will likely spread too thin, lack structure, and won’t hold that signature crinkle top.

The fix:

• If your brownie mix is less than 20 oz, add flour until the total weight is 20 oz.

• Still add the ¼ cup of flour listed in the cookie recipe, even if your mix is already 20 oz.

• Use a kitchen scale for accuracy.

Flour provides the body your cookies need — without it, expect a puddle instead of a puff.

Overbaking the Cookies

Why it’s a problem:
These cookies are meant to have fudgy centers. If baked until fully firm, they lose moisture and become cakey or dry.

What to do instead:

• Bake for 8–10 minutes, or until the edges are set but centers still look slightly doughy.

• Let cookies rest on the baking sheet for 3–5 minutes to finish setting.

Remember: residual heat continues cooking them. Pull early for gooey magic.

Not Spacing Cookies Properly

Why it’s a problem:
The dough expands during baking. If cookies are placed too close together, they’ll run into each other and bake unevenly.

Solution:

• Use a cookie scoop for consistent size.

• Place cookies 2 inches apart on a lined baking sheet.

• Bake in batches if necessary to avoid overcrowding.

Visual appeal matters too — spacing gives each cookie room to shine (and spread).

💡 Bonus Pro Tips

• Use parchment paper for easy removal and even baking.

• Don’t refrigerate the dough unless you’re dealing with a hot kitchen — it’s not necessary and can make cookies too dense.

• Use a cookie scoop (size 40 or 2 tablespoons) to create uniform balls for even baking time and consistent texture.
