Brownie mix cookies are my go to when I need a dessert that tastes like I spent hours in the kitchen but really only took me about 30 minutes start to finish! These double chocolate beauties have that crackly outer shell with a fudgy, chewy center that just makes everybody smile. I brought a batch to our neighborhood cookie exchange last Christmas and they disappeared before the sugar cookies even had a chance. The plate came back completely empty y’all!
They are perfect for after school snacks, potluck parties, holiday trays, or just a Tuesday night chocolate fix. You can dress them up with a little sprinkle of flaky sea salt or keep them classic with extra chocolate chips pressed right into the tops. Trust me, once you try these, you’ll always keep a box of brownie mix in the pantry!
But Can You Make Cookies From A Boxed Brownie Mix?
Absolutely yes! And I promise it is super duper easy. You just take that standard 18 ounce box of brownie mix sitting in your pantry and doctor it up a little bit. The result? A cookie with a crunchy outside and a fudgy center that will make you feel like a baking rockstar. My family could not stop grabbing them straight off the cookie sheet the first time I made them.
You only need one big bowl and a handful of extra ingredients. The batter comes together thick and glossy. A quick 30 minute chill in the fridge keeps the cookies from spreading into sad puddles, so don’t skip that step! The whole recipe, including baking, takes less than half an hour. Betty Crocker can’t compete with this shortcut.
Adding Variety to Cookies
Now the fun part: you can totally customize these cookies to match any craving. Swap out the regular semisweet chocolate chips for creamy white chocolate chips or peanut butter chips. Toss in some butterscotch chips for a caramel y twist, or fold in chopped pecans or walnuts for a little crunch. I love adding a handful of caramel bits and then sprinkling the tops with a pinch of sea salt right before they go into the oven.
During the holidays, red and green M&M’s turn them into the cutest festive treats. For an extra decadent dessert, serve a warm cookie with a scoop of vanilla ice cream and a drizzle of chocolate syrup. If you want a more intensely fudgy experience, my Super Fudgy Brownie Cookies recipe is the bomb too. And when you crave a classic, you can always bake up a batch of my Thick Chewy Chocolate Chip Cookies. The possibilities are endless!
The Perfect Cookie for Chocolate Cravings
There are days when only a deep, dark chocolate flavor will do. These brownie mix cookies hit that spot hard! The texture is a magical cross between a chewy brownie and a crisp edged cookie. When you pull them out of the oven, the edges are set but the center still looks a little soft and gooey. That’s exactly what you want because they firm up as they cool on the baking sheet.
Do not overbake them! I repeat, do not overbake. If you leave them too long, you’ll lose that dreamy fudgy center and end up with a cakey cookie. Nobody wants that. For those gorgeous crackly tops that make the cookies look like bakery jewels, roll your dough balls in powdered sugar before baking. It tastes amazing and gives them the prettiest crinkle finish. In under 30 minutes, you can be holding a warm cookie that tastes like it came from a fancy bake shop.
Step By Step Instructions
Let me walk you through it. The batter is thick, so have your hand mixer or a sturdy wooden spoon ready.
Preheat your oven to 350°F and line a baking sheet with parchment paper.
In a large bowl, combine one 18 ounce box of brownie mix, 1/4 cup vegetable oil, 2 large eggs, 1/4 cup all purpose flour, and 1 teaspoon vanilla extract. Mix until a thick, smooth dough forms. If you want extra tenderness, add an extra egg yolk.
Fold in about 1 cup of chocolate chips. The dough will be very stiff. Use a cookie scoop to portion out 1.5 inch balls and place them 2 inches apart on the prepared sheet.
Chill the dough balls on the sheet in the fridge for 30 minutes. This is key to prevent spreading.
Bake for 8 to 10 minutes. The edges should be set and the tops slightly cracked. Add 1 to 2 minutes only if they look extremely underdone.
Let the cookies cool on the baking sheet for 10 full minutes, then transfer to a wire rack to cool completely. Press a few extra chocolate chips into the tops right after baking for that picture perfect look!
Pro tip: For the chewiest cookies, replace the vegetable oil with melted butter. It makes a world of difference!
How Do You Store The Cookies?
Keep your baked cookies in an airtight container at room temperature and they’ll stay fresh for up to 5 days. Toss a slice of plain sandwich bread in the container and it works like magic to keep the cookies soft.
You can also refrigerate them if you prefer a colder, firmer treat. For longer storage, freeze the baked cookies in a freezer safe bag for up to 3 months. You can even freeze the unbaked dough balls on a sheet first, then pop them into a bag and bake straight from frozen, just add a couple extra minutes to the bake time.
