Brookies are a fun combination of two classic treats in one. It’s a dessert bar made with a chocolate chip cookie layer over a brownie layer.

Do I want a chewy chocolate chip cookie or a fudgy brownie? So often I can't decide which one of these classic desserts I want more! I don't know who first came up with brookies but combining both into one decadent dessert bar is brilliant. 

This is one of my family's top choice of desserts. Our favorite way of eating these brownie cookie bars is by warming them up in the microwave for 15 seconds and topping it with a scoop of vanilla ice cream. 

How about a dessert sundae made with these bars? It's a great way to serve up something fancy. Pour some chocolate sauce on top of the ice cream and warm brookies and you'll have the ultimate treat! 

So are you excited to make these yet? Let's start with what you will need if you make them completely from scratch. Read on for a shortcut method too! 

Ingredients for Brookie Bars

Common dry ingredients: All purpose flour, baking powder, baking soda, salt.

Unsalted Butter: I always use unsalted butter so I can control the amount of salt. For the brownie batter, you will be using melted butter so it does not need to be room temperature but it's best to use room temperature butter for the cookie batter. 

Cocoa Powder: I use Dutch Process cocoa powder for the best chocolate flavor in my brownie batter. It also reacts better with baking powder. 

White Sugar: The amount of sugar in this brownie recipe is slightly less than other recipes you may see because I've added chocolate chips to the batter which add some sweetness. You will also need sugar for the cookie dough batter.

Brown Sugar: Use either dark or light brown sugar. Brown sugar adds sweetness and also results in soft and chewy chocolate chip cookies.

Vanilla Extract: Adds flavor. Always use quality extract not imitation for best results.

Large Eggs: Eggs provide structure, moisture and richness. Use room temperature eggs for both batters.

Espresso Powder: This is not necessary and can be skipped but I find that a little espresso powder enhances the chocolate flavor. You will not be able to taste the espresso.

Semi-Sweet Chocolate Chips: I do not recommend bittersweet chips for this recipe unless you prefer it to be a lot less sweet. The semisweet chips will balance the amount of sugar in the recipe for both batters. 

How Do You Make Brookies?

You might be thinking this is going to require some extra dishes. While you will have to make two different batters, this doesn’t necessarily mean you will have extra cleanup. You can use one mixing bowl if you like. Just give it a quick rinse in between prepping each batter.

Here's a quick overview but be sure to read the recipe card for full details.

Step 1: You will need to prepare your baking pan first. I use a 9x13 dark metal pan that’s buttered and then lined with parchment paper and buttered again for easy removal. 

Step 2: Prepare the brownie batter according to the details in the recipe below. Spread the batter into the prepare pan.

Step 3: Make your chocolate chip cookie dough according to the recipe below and spread it over the brownie batter to create an even layer. The batter is thick so it may be difficult to spread.

I find it easiest to drop spoonfuls of cookie dough all over the pan and then gently spread it with an offset spatula. Be gentle, it may take some time to get it even. 

Step 4: Once the batters are layered, you can add extra chocolate chips on top if you want. I like the way it looks so I sprinkle on a few.

Step 5: Bake the batters for 25-28 minutes or until a toothpick inserted into the center comes out clean or with a few crumbs on it.

(Tip: You may need to add aluminum foil over it toward the end of baking if it starts to brown too quickly. See recipe notes.)

Want to Take A Short Cut?

I use my own favorite homemade brownie recipe and chocolate chip cookie recipe but you can easily follow this same recipe by taking a slight short cut and using a boxed brownie mix and boxed chocolate chip cookie mix. My preferred boxed mix brand is Ghirardelli Dark Chocolate.

Storage

Store the brookie bars in an airtight container at room temperature for up to one week. You can also freeze the bars in an airtight container between layers of wax paper for up to three months. 

Variations for Making Brookies

• Swirl the two batters before baking instead of having two distinct layers. This is what I did with my pumpkin brookies!
• Add Oreo cookies between the two layers for Oreo Brookies. See my recipe for Oreo brownies for tips on how to arrange the cookies.
• Use butterscotch chips instead of chocolate chips for Butterscotch Brookies.
• Use Reese's Pieces instead of chocolate chips in the cookie dough for some peanut butter flavor and color.
