Guinness stout chocolate brownies

These are the best brownies I’ve ever had in my entire life – Read the text I received few hours after I dropped a plate with a couple of these fudgy guinness stout chocolate brownies at my neighbor’s door.

The nuttiness of the stout enhances the flavor making these Guinness stout chocolate brownies so rich and fudgy, it will be love at first bite.

I mentioned in a previous post  we don’t really drink but I do happen to love making grown up treats, like these out of this world stout brownies. Now of course, some might say “why on Earth would you ruin a good batch of brownies just by adding stout to it?” or even worst “why opening a bottle of stout just for a pan of brownies?”. My lovelies, if you have never tried stout brownies, you are missing out.

While you can hardly taste the beer in these brownies, the stout enhances the flavor making these one of the richest and moistest brownies in the whole wide world!

Fudgy Guinness stout chocolate brownies recipe from

I’ve made these stout chocolate brownies for the first time last year on St. Patrick’s day and have had a post-it note in my office ever since to make them again and share my thoughts with you.

The recipe comes from Bon Appetit and I pretty much kept it the same. Actually, the only thing I did not do was the stout chocolate frosting. As soon as I removed my brownies from the oven I grated about 1 ounce of dark chocolate over let and let the warmth of the brownies to slowly melt it. I did play a little bit with some melted chocolate on few of them once they were cooled, but whatever you decide to do, these brownies will soon become one of your favorite!

Keep in mind, because these are really rich and moist, it’s best to cut the brownies in 20 pieces. A little bite will satisfy your cravings.

Of course, the hardest part is actually waiting for the brownies to cool down so you can cut them. You need a lot of will powder. My suggestion is to make them the night before and just let cool overnight on the kitchen counter. You might end up waking up in the middle of the night thinking about them, but don’t give it. Let them cool completely before digging in.

If you do not have any stout on hand and don’t feel like buying a six-pack  just for these brownies, go to your local (cost plus) World Market. They sell individual bottles.

    Loving these moist fudge-stouty brownies, Roxy! We’ve been on a major chocolate kick at our house (putting off the inevitable diets for spring until after St. Patty’s Day), so I must make these…this weekend! Thanks for sharing, girl. Pinning!

    I might believe you if you didn’t always say, introducing a new recipe, that these were the best brownies ever. I fell for that once and ended up quite disappointed so I will be more cautious from now on.

    I tend to keep Guinness, Jameson’s and Bailey on hand to sip and to cook with. I tend to be a bit biased coming from an Irish heritage. The one thing I have not made is brownies because my family is very particular about their brownies. Between your recipe and another I saw that had stout and baileys, I can’t figure out which one to try first! I have pinned this to my “Good to Be Irish” board and am now a new follower!

    Of all the booze-related treats I’ve made, why oh why have I never put stout in my brownies?! This is a genius idea and the way you describe them is just drool-worthy. Checking out the rest of your blog! So happy to connect through Marvelous Mondays. xx Danni

    I made these for work the other day and I’ve just had the last piece which I had kept aside for myself. Aaamazing. I have a go-to basic brownie recipe I use that is cocoa powder based. This will be my other go-to for a super chocolatey brownie. Now that I’ve made this one, I can’t wait to make it again. It’s a brownie on a different level. I’ve baked with Guinness for a few years so I know how great it is in desserts. I put a small layer of cream cheese icing on these so that I could color it green. So good.
