Guinness Brownies

I love these Guinness brownies. Originally I had no plans of eating them but one thing led to another and here we are a few hours later with an empty pan in front of me and a glass of milk in my hand. I know, they have BEER in the batter. Gross, right?

Actually, not so much. The dark brew brings in an unbelievable richness that pairs oh-so well with the chocolate. Almost like blow your mind good. I was so skeptical when I put them into the oven because it had a super strong aroma, but the baking brownies filled my home with a beautiful chocolate sent that had me almost drooling as I waited for the timer to go off. I cut off the smallest corner to nibble on and by the time I was ready for pictures half of them were missing. >insert embarrassed chocolate covered face here<

So give them a try. These are a fun, and festive, way to celebrate St Patrick’s day and I hope you give them a chance.

I’ll walk you through the steps. Seems like you guys enjoy the posts where you see how I made the recipe so I’ll try to do those types of posts more often. For this one you want to start with a bottle of dark beer. I chose Guinness since it is an Irish dry stout and these are for St. Patrick’s day. Pop that sucker open and set it aside.

Next you want to combine your dry ingredients. This should be fairly simple since there are really only two; flour and dark cocoa.

Guinness Brownies dry ingredients

Set those aside and grab your stand mixer. Toss in some softened butter with a bit of sugar and beat until it’s nice and fluffy. You’ll want to make sure you scrape down the bowl so it all stays nice and cozy in the middle.


Stir in some eggs and a dash of vanilla…


And move on to the best part. CHOCOLATE. Well, chocolate and butterscotch. You’re going to combine the two in a heat safe bowl.


Microwave for one minute, give it a stir, and continue to heat it until melted. Make sure you stir it every 20 seconds to keep it from burning.


Fold that, along with your dry ingredients, and Guinness into your butter and egg mixture until you’ve got a wonderful batter.


Pour into a paper lined pan and stick it into the oven.

Guinness Brownies recipe

I mixed in some chocolate chips but you probably don’t really need to. It’s plenty rich all on it’s own. Wait until these have cooled slightly, cut, and enjoy. They are especially delicious with a generous scoop of ice cream plopped right on top!

I would probably eat the whole pan and then have to explain to my bf how I got drunk off a pan of brownies... Although, I guess that does sound like a reasonable way to spend St Patricks Day! Thanks for the recipe, and the warning about the smell before they bake. That probably would have freaked me out!
