You’re going to love these brownies topped with a cookie dough layer and a chocolate fudge drizzle!
This recipe starts with a rich fudgy brownie with a thick layer of eggless cookie dough and an extra layer of chocolate. Just because everything is better with extra chocolate.

Cookie Dough Brownies
But these cookie dough brownies also rank up there as one of my all time favorites. I just can’t say no to brownies or chocolate chip cookies and here I get both.
I’m a person who loves cookies but I’m all about the dough first. Cookie dough is the best therapy for me.
I don’t need fancy flavor profiles and gourmet ingredients, just give me a bowl and let me eat to my heart’s content. I promise I’ll love you forever.
A version of these cookie dough brownies has been around my family ever since I was a little girl. It was always a favorite at our house.
Chocolate Chip Cookie Dough Brownies
However, I thought the original brownies could be even better. I switched up the brownie base to my favorite fudgy brownies ever!!
And then, to make them even more awesome, I added mini chocolate chips to the cookie dough. Somehow when we were little we never noticed the cookie dough didn’t have any chocolate chips.
But now in my cookie dough connoisseur days, their absence is very apparent and easily remedied. I also swapped out a chocolate shell topping for a fudge drizzle.

The only downside to making these is waiting for them to cool enough to spread on the dough and top chocolate layer on, and then waiting for that chocolate layer to set up.
But they are oh-so amazing when they are done.
Some more of my favorite chocolate recipes are these Chocolate Cookies stuffed with caramel, Chocolate Caramel Shortbread Bars, and Chocolate Dipped Chocolate Chip Cookies.

Cookie Dough Brownie Recipe
To Make The Brownies
- To make the brownies, preheat oven to 350 F. Grease and flour a 9 x 13 inch pan. Melt the butter in a large microwave safe bowl. Whisk in the oil, sugar, eggs, vanilla extract.
- Beat in the cocoa, flour, salt and baking powder. Spread batter into prepared pan. Bake for 25-30 minutes or until an inserted toothpick comes out with a few crumbs. Let cool completely.

To Make The Cookie Dough Topping
- In a medium mixing bowl, cream together the butter and sugar. Stir in milk alternately with the flour. Add the mini chocolate chips and stir until they are well distributed.
- Spread the cookie dough mixture on top of the brownies. Cover and place in the refrigerator.
To Make The Fudge Drizzle
- Melt the butter in a medium microwave-safe bowl. Stir in the cocoa powder, corn syrup, powdered sugar, and enough milk or heavy cream to make a smooth consistency. Microwave to 20 seconds and stir.
- Drizzle the warm chocolate on top of cooled brownies. Let cool and cut into bars.

In case you’ve made these brownies before and remember them differently, this is what the original recipe looked like.
If you want, you can melt a bag of chocolate chips with a couple of tablespoons of oil and spread it over the cookie dough. But, personally, I like the fudge drizzle better.

BEFORE YOU MAKE BAKE THE FLOUR! Raw flour can give you salmonella so make sure you microwave/bake before you use it in the cookie dough. Other than that great recipe.?
Tate – Good point. Thank you for that reminder.
Very delicious! A big step up from regular brownies. I recommend eating it with vanilla ice cream because that makes it even more delicious! Also, don’t pack the dry ingredients because then it isn’t the right amount, I made that mistake, but it was still delicious and tastes better after you let it chill.
I’m so glad you like the brownies, Anna!
I dont have a big enough tin for it since it is only a 8×12 inches pan. Will this size still work? Thanks!!
That will work fine, Claire.
Hi, these are delicious! Glad I tried the recipe (:
Very upsetting that this recipe appeared under an “eggless” search. There are eggs in the brownie.
Hi! I am baking these tonight! Is the T tablespoons? New baker here 🙂
Hi Olivia! Yes the “T” stands for tablespoon. I hope you enjoy.
