I have spent the better part of the last couple weeks of my life on these brownies, no joke. I wanted the most perfect version of a guiness brownie to share with you.

But before I dive into all that, I have a confession. Get ready.

I don’t like beer.

I know, I know. How can I post a recipe with beer in it when I don’t like beer. I can’t explain it except to say that it’s my dad’s fault. I clearly got my taste buds from him – he also does not like beer. It’s a thing and he passed it on to me. I have tried so many times to like it. It just won’t work.

So I fully expected to not like these brownies. I have a coworker who loves Guiness like I love cake, so I knew he’d help out with the taste testing.

Crazy thing is, I’m super in love with these brownies. I can taste the Guinness, but it mostly just enhances the flavor of the chocolate in the best way possible. Seriously amazing. And they seem to get moister the second or third day.

So back to the whole testing these thing. I started with these Quick and Easy Brownies. They are the jam, and pretty much everyone that tries them loves them. So I started with those.

But oh my, the bubbles in Guinness! The first version was basically like chocolate cake. No good.

I proceeded to make like 6 or 7 more versions – I lost count. Messing around with the amount of Guinness, eggs and some other ingredients to get the perfect amount of fudgy and cakey. I am totally in love with the final texture of them.

I also wanted them to have plenty of Guinness flavor. Truth is, I was never totally able to please my Guinness loving coworker. I added almost an entire beer and he still didn’t think it tasted that much like Guinness. He and his family (and everyone else) loved the brownies, but I decided I’d have to drown a brownie in Guinness before he’d think it tasted enough like it. Craziness.

I still think they taste like Guinness, but maybe I’m just sensitive to beer taste. I guess you’ll just have to make them and decide for yourself. 🙂 They’re totally worth it.

    I absolutely love this recipe. The only reason I ever buy alcohol is to cook, and Guiness is a staple in my house for brownies, cake, stew, etc. I have to bake for a touch longer than called for, but really, not much. Everyone I have served these to have raved and have asked for the recipe. My older son really only want these now.
    Thanks so much for the recipe!!!!
