Did you know Guinness is the worldwide drink of choice to celebrate Irish culture? I've been to the Guinness factory in Dublin and it was such an interesting and fun experience! These delicious moist Guinness Chocolate Brownies are the perfect way to celebrate St Patrick's Day (or any day you fancy a tasty chocolate brownie!) The addition of Guinness to the brownies intensifies the flavour and makes them super gooey and rich. I absolutely love Guiness in cakes and baking, my Chocolate Guiness Cake with Baileys Buttercream is my favourite cake ever!
For the full recipe with measurements, head to the recipe card at the end of this post.
How to make Guinness Chocolate Brownies
Start by melting dark chocolate, butter and Guinness in a pan on a low heat until glossy and smooth. Let the mixture cool for 10 minutes. In a bowl whisk together eggs and light brown sugar.
Then add the chocolate mixture to the egg mixture and whisk it together. Finally add plain flour and baking powder, and mix in. Pour the mixture into a baking tin and bake for 30 minutes.
When the Guinness Chocolate Brownies are baked, leave them to cool before slicing into squares.
The Guinness Chocolate Brownies are so incredibly moist and fudgey! And warning, they're rather addictive too!
I highly recommend eating them warm! They would be amazing with ice cream too.

I love the idea of Guinness brownies. Bet they taste yum. Unfortunately Guinness is off our menu on account of the malted barley....... Darn!!!
Kat BakingExplorer
Ah that's a shame, maybe there is a barley free stout you could use?
Stuart Vettese
Guinness really adds a certain something to chocolatey cakes doesn't it? These look well lush 🙂
Kat BakingExplorer
It goes so perfectly with chocolate 🙂 thank you!
Alice Lau
Chocolate & stout are two favourites of mine. Coupled with brownies and you have a winning recipe! Ever tried them as a base for bread before. Equally tasty!
Kat BakingExplorer
Never thought of using it in bread before, thanks for the tip!
Simran
Any substitute for eggs in the recipe ?
thebakingexplorer
Hi Simran, I have never made this cake without eggs, however there are many common egg substitutes you could try!
Maha
Is there a way I can substitute Guinness out and make them the same texture. Also how do you bake your brownies so evenly throughout (from the outer edge to the inner part)
thebakingexplorer
I've only ever made them with the Guinness. You could try a non-alcoholic beer if you're trying to avoid alcohol. I don't have a particular technique to make them even, I just follow the recipe and they turn out that way.
Jason
Does the alcohol get retained in these? Or baked out. I don’t think I could make brownies in my house without the kid wanting some!
thebakingexplorer
Hi Jason, based on a quick google search, the general information seems to be that around 35% of the alcohol remains after 30 mins of baking. Which would be 70ml of guinness, spread amongst 12 slices would be less than 6ml per slice. So a very tiny amount!
