Guinness Brookies

These Guinness Brookies are the dessert I never knew I needed. Guinness beer infuses brownie batter with a unique richness that is leveled up once layered with chocolate chip cookie dough. While they don’t taste of beer exactly, there’s no denying the fun twist the stout imparts on these brookies. They are fudgy, rich, and completely decadent — and they are just the thing to celebrate St. Patrick’s Day (or any time you need a sweet but unique treat)!

If you are looking for a fun and unique treat with some Irish flair, look no further. I got you.

These Guinness Brookies are everything I didn’t know I needed in a dessert.

Stout beer infuses brownie batter with a unique richness and flavor that yields a super fudgy, dense brownie. They don’t taste of beer, per say, but they have a note of something different going on, and it is delicious.

It works so well with the rich chocolate and vanilla flavors. A match made in heaven!

What makes brownies even better?

Layering them with chocolate chip cookie dough, of course!

Brookies – aka, the combination of brownies and cookies in one pan – are one of my favorite creations to come out of the culinary world. It’s the best of both desserts, and they really work so well together.

The bites where you get a little bit of both are the BEST.

Enjoy these with a big glass of milk (or hey, stout beer!), and you’ll be thanking me. I promise!

While these may seem complicated to make, I assure you, they are not.

We make two batters – stout-infused brownie and cookie dough – and layer them together in a pan. That’s really it. The oven does the rest!

Ingredients You Need to Make These Guinness Brookies:

For the Brownie Batter:

• Stout beer (I prefer Guinness but any stout you love will work here)
• Unsalted butter
• Semisweet chocolate
• Light brown sugar
• Granulated sugar
• Eggs
• Vanilla extract
• Salt
• All-purpose flour
• Unsweetened Dutch-processed cocoa powder

For the Cookie Dough:

• Unsalted butter
• Light brown sugar
• Granulated sugar
• Vanilla extract
• Egg
• All-purpose flour
• Salt
• Baking soda
• Baking powder
• Semisweet chocolate chips

How to Make These Guinness Brookies:

For the Brownie Batter:

• Add the beer to a small saucepan and set it over medium heat. Bring to a simmer and cook until it is reduced to roughly ½ cup, about 20 minutes.
• Place the butter in a large microwave-safe mixing bowl and melt the butter in the microwave. Add the chopped chocolate to the hot butter and stir until melted.
• Measure out exactly ½ cup of the reduced beer and add it to the butter mixture.
• Whisk in the sugars, mixing well to combine.
• Whisk in the eggs, vanilla, and salt until the batter is slightly airy, about 5 minutes.
• Whisk in the flour and cocoa powder until the batter is smooth and glossy.

For the Cookie Dough:

• In a mixing bowl, whisk together the melted butter and two sugars until they are smooth.
• Beat in the vanilla and egg.
• Add the flour, salt, baking powder, and baking soda to the wet ingredients and mix to combine, being careful to not overmix.
• Fold in the chocolate chips.

To Assemble:

• Preheat the oven to 350°F and line a 9 x 13-inch baking pan with parchment paper. Spray both the pan and the paper liberally with cooking spray.
• Pour the brownie batter into the pan, spreading it out in an even layer.
• Dollop the cookie dough over the top of the brownie batter, distributing it as evenly as possible. It will be quite a bit thicker than the brownie batter, so be careful when doing this. The idea is for the two to be set in the pan together but not totally combined. Sprinkle over the remaining ⅓ cup of chocolate chips.
• Cover the pan with tin foil and then transfer to the oven and bake for 20-25 minutes. Remove the foil and continue baking for another 15-20 minutes. The brookies are done when the cookie dough is lightly golden.
• Allow the brookies to cool COMPLETELY in the pan before attempting to slice them – they will be very soft while warm.

These brookies are, simply put, insane. They are one of the best things I’ve ever baked.

Baking up a pan of these for friends and family will make you very popular! Especially on St. Patty’s Day!
