INGREDIENTS FOR BROOKIES BROWNIES

Here are some notes about the ingredients. For a full list of ingredients, check out the recipe card at the bottom of the page.

All purpose flour - regular all-purpose flour is perfect to make fudgy brownies and chewy cookies. I only ever use unbleached flour.
Unsalted butter - the best brownies and chocolate chip cookies that have a chewy texture are made with butter.
Pure vanilla extract - vanilla does wonders to enhance the flavor of the chocolate and it is a very important ingredient in chocolate chip cookies. I like this Madagascar Bourbon Vanilla extract.
Granulated sugar - simple fine white granulated sugar keeps these brownies moist. There is slightly less sugar than my typical brownie recipe to account for the additional sugar in the cookie dough.
Brown sugar - you can use light brown or dark brown sugar. I like the added flavor the molasses gives with dark brown sugar.

Egg - 2 whole eggs will provide majority of the structure in these brownies and 1 egg yolk is just right to make the small batch of cookie dough.
Salt - don't skip this otherwise the these brookies will be too sweet.
Dark chocolate - anything between 60 and 85% cocoa solids will work. I prefer bittersweet chocolate with 70% cocoa solids or extra dark chocolate for the brownies, and these bittersweet chocolate callets are great for the cookie dough.

STEP BY STEP INSTRUCTIONS: HOW TO MAKE BROOKIES

STEP 1.) First make the cookie dough. Combine butter and sugars. Melt the butter in the microwave or on the stovetop until it is JUST melted so it is still pale yellow and creamy-looking. Basically, gently melt it until there is still some solid butter left and then stir off the heat until the residual heat gently melts the remaining solid butter. Combine melted butter with brown sugar and granulated sugar in a large bowl and mix to combine.
STEP 2.) Add remaining ingredients. Mix in egg yolk and vanilla. Sprinkle in flour, baking soda and salt and fold it in. Fold in chocolate chips.
STEP 3.) Make dough balls. Roll cookie dough into about 18 small balls, transfer them to a lined plate or tray, cover and refrigerate while you make the brownie batter.
STEP 4.) Make the brownie batter. Melt chocolate. Combine chocolate and butter in a heatproof bowl over a saucepan of simmering water and stir frequently until melted, or you can do this in the microwave gently with frequent stirring so it doesn't burn.
STEP 5.) Mix eggs and sugar. Combine eggs with sugar and whisk until very thick, pale and lightened up a bit. Mix in vanilla and salt.
STEP 6.) Combine eggs and chocolate. Add the warm chocolate mixture to the egg mixture and mix it in well.
STEP 7.) Add dry ingredients. Sprinkle in the flour and fold it in until evenly combined.
STEP 8.) Bake. Scrape about half of the brownie batter into prepared pan and spread it out evenly. Flatten half (9) of the chilled dough balls into discs and lay them over the batter in three rows of three. Spread remaining brownie batter on top to cover the cookie dough, and then place remaining flattened dough balls over top. Bake for 20 minutes, then reduce temperature to 325°F and bake for another 15-20 minutes until a skewer comes out with a few moist stick crumbs attached.

EXPERT BAKING TIPS

Measure flour accurately. Too much flour leads to a dry brownie and crumbly cookie so be sure to use a scale or use the spoon and sweep method without packing the flour into the measuring cup.
Mix the eggs with the sugar first to make glossy brownies instead of stirring the sugar into the melted chocolate. Sugar cannot dissolve in fat, but it can dissolve in the water within egg whites.
Do not under-bake. These brookies will take longer than normal to bake since there is a lot of dough/batter in one pan, but be cautious not to over-bake as the edges will dry out and become too hard. A skewer inserted into the brownie portion should come out with a few moist sticky bits attached. If it comes out clean then the brownie portion may be over baked, and if it comes out with wet batter then they are not cooked through yet.

RECIPE FAQ

What type of chocolate should I use for brookies brownies?

I use bittersweet chocolate with 70% cocoa solids which makes perfectly chocolaty brownies. Semisweet chocolate will be too sweet when combined with the cookie dough.

What makes brownies chewy vs. fudgy?

Brownies can be chewy or fudgy, or a blend of both. Brownies get their chewiness from the right amount of sugar, and a higher ratio of sugar:butter, as well as a higher ratio of chocolate:butter. More butter gives a softer fudgier texture, while more chocolate and more sugar gives a chewier texture thanks to the hard cocoa butter content. Cocoa butter is harder than butter at room temperature so it will give more resistance to the bite, creating the perception of chewiness. More butter will make brownies soft and melting for a fudgier texture.

How to make brownies with a shiny crust on top?

It's all about dissolved sugar. Whisk the sugar into the eggs first. This will help it dissolve some, and also the bonds between sugar and egg proteins is what creates the thin tissue like crust. To help this along, always use room temperature (not cold) eggs. The warmer temperature helps sugar dissolve. The longer you whip the eggs with the sugar, the thinner and shinier the crust will be.
TIP: to bring eggs to room temperature quickly, submerge them in warm water for 10 minutes.

Can I use all cocoa powder to make brookies brownies?

This recipe requires melted chocolate for the brownie portion. Melted chocolate gives a fudgier texture because of the cocoa butter content that has a higher melting point. If you prefer to make brownies with cocoa powder only, then check out my Better Than Box Brownie Mix recipe which have a chewier texture.

How do I know when brownies are finished baking?

If your brownies turn out dry, then it is most likely because they are over-baked. These brookies are ready when a skewer inserted into the center where there is brownie batter comes out with a few moist sticky crumbs attached - not wet batter, and NOT clean. If the skewer is clean then the brownies are over-baked and if the skewer has wet batter then they are still raw.

Why are my brookies dry?

The number one reason why these would turn out dry is if they are over-baked. Check on them at 25 minutes. Also, take care to measure the flour accurately.

How do I store brookies brownies?

Brookies keep really well at room temperature as long as they are stored in an airtight container to prevent drying out. If you plan to keep them for more than a couple of days, then store them in the fridge.

Why did my brownies sink in the middle?

Brookies will sink in the middle if you over-beat the eggs and sugar for the brownie batter, if there is not enough flour or if they are under-baked. When you beat the eggs, you are incorporating a lot of air which will cause the batter to soufflé or puff up in the oven. As the brownies cool, the air bubbles will collapse and they will fall. To prevent this, be sure to only beat the eggs for about 2 minutes and then bake the brownies evenly. If you think your oven runs hot, then bake at a slightly lower temperature for a longer time because if the temperature is too hot, the brownies will puff up and over-cook on the edges while the center is still raw.
