What Are Brookie Bars?

Brookies have been making the rounds for several years now. Whoever the genius was who first looked at two of the finest foods – brownies and cookies — and decided to combine them into a third awesome thing, we salute her or him!   

Brookies come in many shapes and sizes, from bars to cupcakes, from regular to peanut butter to red velvet. This Brookies recipe teaches you the basics of a standard Brookie Bar, which is a layer of brownie baked over and into a layer of cookie.

Check out U.S. History Scene’s article on the history of the brownie to learn more about the rich and scandalous backstory of half of this treat!

What Ingredients Do You Need To Make Brookie Bars?

This easy Brookie recipe is made in two layers. The cookie layer requires softened butter, dark brown sugar, granulated sugar, vanilla, an egg, flour, salt, baking soda, and a cup of semisweet chocolate chips.

The brownie layer, a close cousin of Cosmic Brownies, uses granulated sugar, melted butter, vanilla, three eggs, cocoa powder, flour, baking powder, and salt. All items you likely already have in your pantry and fridge, so no running around town required!

Brownies and cookies are the yin and yang of this treat. First, whip together a batch of cookie dough, blending wet and dry ingredients, then spread them over the bottom of your baking pan. Next, mix up some brownie batter, and pour it on top of the cookie base! Finally, bake to perfection.

Ingredients

Cookie Layer:

  • 3/4 Cup Butter, Softened
  • 3/4 Cup Dark Brown Sugar, Packed
  • 1/2 Cup Granulated Sugar
  • 1 Teaspoon Vanilla
  • 1 Large Egg
  • 1 3/4 Cups All-Purpose Flour
  • 3/4 Teaspoon Salt
  • 3/4 Teaspoon Baking Soda
  • 1 Cup Semisweet Chocolate Chips

Brownie Layer:

  • 1 1/2 Cups Granulated Sugar
  • 3/4 Cup Butter, Melted
  • 2 Teaspoons Vanilla
  • 3 Large Eggs
  • 2/3 Cup Cocoa Powder
  • 3/4 Cup All-Purpose Flour
  • 1/2 Teaspoon Baking Powder
  • 1/4 Teaspoon Salt

Instructions

  1. Preheat the oven to 350 degrees. Spray a 9X13 inch baking dish with nonstick cooking spray. Set aside.

Make the Cookie Layer:

  1. In a large mixing bowl, cream together butter, brown sugar, granulated sugar, and vanilla using an electric mixer on medium speed, until the mixture is well combined and creamy.

  2. Add the egg and continue to cream the mixture until it becomes light and fluffy, or for about 2 minutes. Set mixture aside.

  3. In a medium mixing bowl, whisk together flour, salt, and baking soda until evenly combined. Gradually mix flour mixture into butter mixture until just combined. Mix in chocolate chips.

  4. Spread cookie dough evenly into the bottom of the prepared baking dish covering the pan completely. Set aside.

Make the Brownie Layer:

  1. In a medium mixing bowl, mix together granulated sugar, melted butter, and vanilla. Add eggs and mix until completely combined.

  2. Stir cocoa powder into sugar/butter mixture and mix until well combined. Add flour, baking powder, and salt and mix until incorporated.

  3. Pour brownie mixture evenly over cookie dough, covering the dough completely.

  4. Bake in preheated oven until a toothpick inserted into the center comes out with just a few moist crumbs (not batter, just a couple of crumbs), about 40-45 minutes. Allow to cool completely. The brownies need this time to finish setting. I prefer to cool them then refrigerate them overnight before serving.

Recipe Notes For Brookie Bars:

Duration of baking: I like my brownies to be more on the fudgy side of done. To achieve this consistency, I bake them until a toothpick inserted in the center comes out with a few moist crumbs. In my oven, the Brookies reach that point in about 45 minutes in my oven. If you like your brownies a little more set, bake until the toothpick comes out clean, 47 minutes in my oven. Just don’t over bake, or both layers will be ruined!

Brookie cupcakes: To turn these bars into cupcakes, bake your brookies in a muffin pan. The recipe remains the same, but baking times will vary according to your oven and pan. In general, you can expect to cut the cook time in half. Remember to test for the desired level of doneness using a toothpick. This variation is a great option for parties and bake sales!

Brookie Bars with brownie mix: If you are in a rush or if you have run low on cocoa powder, feel free to use a store-bought brownie mix. This will save a couple of minutes and conserve your cocoa supply! My family prefers the homemade version, but shortcuts like ready-made mixes have certain perks as well, especially on busy evenings!

Egg selection: You may have noticed that stores sell both grade AA and grade A eggs. There are a total of three grades — grade B being the third — but grade B eggs are only used for powdered or liquid egg products. Egg grades are determined by examining both the shell and the interior (using a process called “candling.”) Grade A eggs have smaller air pockets and firmer whites. Both AA and A eggs are intact, smooth, clean, and regularly shaped. The good news is that both grades are also fine for baking! Take a gander at Southern States’ article on grading for more in-depth information about egg evaluation. 

Melting butter: While I enjoy the convenience of melting my butter in the microwave, it is important not to overdo it, or you could scorch the other ingredients and accidentally pre-cook your eggs! Keep an eye on the melting butter (or let it cool for a minute after melting), and always avoid pouring boiling liquid into your brownie mixture.

Can You Make Brookie Bars Ahead Of Time?

You can indeed! Brookies will keep in the fridge for three to four days, and in the freezer for up to a month. If you are planning ahead for a family gathering or social event, Brookie Bars are the way to go. As an added bonus, they stack and store neatly, which is ideal for conserving fridge or freezer space.

How Do You Freeze Brookie Bars?

You can store this dessert for several weeks in the freezer. Place leftover bars (or cupcakes, see below!) in a resealable bag or container for optimal freshness. You may want to separate layers with wax paper for easy thawing and arranging. Some people think they taste even better straight out of the freezer!
