Brownie Mix Cookies

I still remember the day I turned a box of brownie mix into cookies. It wasn’t planned—I had a craving for something chocolaty but didn’t want to wait for a full batch of brownies to bake and cool.

So, I tweaked a few things, scooped the dough onto a baking sheet, and hoped for the best. What came out of the oven was a revelation: soft, fudgy cookies with that signature brownie chew, but in perfect handheld form.

Since then, these brownie mix cookies have been my go-to when I need a quick chocolate fix. They’re ridiculously easy, come together in minutes, and require just a handful of ingredients.

They’ve also saved me on more than one occasion when unexpected guests dropped by or when I needed a last-minute treat for a gathering. No one ever suspects they start from a boxed mix. They taste just as rich and indulgent as homemade!

I’ll walk you through each step, share some pro tips, and even give you a few creative twists to make them your own. Let’s get baking!

Short Description

Brownie mix cookies are soft, chewy, and packed with rich chocolate flavor. Made with just five simple ingredients, these cookies come together quickly and taste just like homemade brownies in cookie form.

Key Ingredients

• 1 box (18 oz) brownie mix
• 1/4 cup all-purpose flour
• 2 large eggs
• 1/4 cup vegetable oil .
• 1 cup chocolate chips (optional)

Tools Needed

• Large mixing bowl
• Whisk or spatula
• Baking sheet
• Parchment paper or silicone baking mat
• Cookie scoop (optional)

Cooking Instructions

Step 1: Preheat Your Oven

Set your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking and make cleanup easier.

Step 2: Mix the Dough

In a large bowl, whisk together the brownie mix and flour until evenly combined. Add the eggs and vegetable oil, then stir until a thick, sticky dough forms. The batter will be denser than typical cookie dough—this is normal!

Step 3: Add the Chocolate Chips

Gently fold in the chocolate chips (if using). Try not to overmix, as this can make the cookies tough.

Step 4: Scoop and Space

Using a spoon or cookie scoop, drop tablespoon-sized portions onto the prepared baking sheet, leaving about 2 inches of space between each cookie. This ensures they don’t spread into each other as they bake.

Step 5: Bake

Bake for 8–10 minutes, or until the edges look set but the centers remain soft. The cookies will continue firming up as they cool, so don’t overbake!

Step 6: Cool and Serve

Let the cookies rest on the baking sheet for 5 minutes, then transfer them to a wire rack to cool completely. Enjoy warm or at room temperature!

Mistakes to Avoid & Solutions

1. Overmixing the Dough

Overmixing can make the cookies dense and tough. Stir just until everything is combined.

2. Overbaking

The cookies should look slightly underbaked in the center when removed from the oven. They’ll firm up as they cool.

3. Using a Brownie Mix with Syrup Packets

Some mixes contain syrup or multiple packets, which can alter the texture. Stick to a classic dry mix.

4. Skipping the Parchment Paper or Silicone Mat

This prevents sticking and ensures even baking. If you don’t have one, lightly grease your baking sheet.

5. Not Letting the Cookies Cool on the Baking Sheet

If you move them too soon, they might fall apart. Let them set for at least 5 minutes before transferring to a wire rack.

Serving and Pairing Suggestions

With a Glass of Milk: The ultimate classic pairing!

Drizzled with Caramel or Chocolate Sauce: Extra indulgence for special occasions.

Ice Cream Sandwiches: Place a scoop of vanilla or chocolate ice cream between two cookies.

Topped with Sea Salt: A pinch of flaky sea salt enhances the rich chocolate flavor.

With Coffee or Espresso: The bitterness balances the sweetness beautifully.

Storage and Reheating Tips

At Room Temperature: Store in an airtight container for up to 4 days.

Freezing: Freeze baked cookies in a zip-top bag for up to 3 months.

Reheating: Warm in the microwave for 10–15 seconds to bring back the gooey texture.

FAQs

2. How do I make these cookies more fudgy?
