Chocolate Guinness Brownies

Rich, dense, fudgy chocolate Guinness brownies: 

Guinness Brownies

Something not a lot of people in the blogworld know about me:

I happen to really love beer.


My first beer experience took place in Sapporo, Japan, and it wasn’t exactly a wonderful welcome into the alcoholic world. I was six years old, eating dinner with my family, and the only drinks on the menu were beer and soda. I loathe soda… and I asked for apple juice, which they sadly did not carry.

So I ordered the next best thing: a pint of beer.

I still remember my mom’s face… and how she asked my dad with alarm, “They’re not really going to bring her a beer, are they??”

Guinness Brownies

Yes, they really did bring me a beer.

They set the glass right down on the table in front of me, and my mother was completely horrified. As were the people at the next table.

But my dad was amused.

He told me, “Go ahead and drink it, Katie.” So, feeling all grown-up and important, I took a sip. Just one sip. Then I made a face and pushed the glass across the table. The waiter laughed and brought me a water.

And it would be almost twenty years before I’d change my opinion of beer.

Fudge Brownies

While Guinness is not normally my beer of choice (I’m an IPA girl), it does extraordinary things to these chocolate brownies, adding over-the-top richness and deep chocolate flavor.

I am in love.

Question of the Day: Beer: do you love it or hate it?

I used to think I hated it… But that was back in college when my idea of beer was 6-packs of Bud Light (I call it “beer water”) being downed 8 or 9 at a time by people who really didn’t care about the flavor and were only drinking to get drunk. Craft beer is an entirely different experience: in each beer, it’s not uncommon to detect three or four (or five or six!) distinct flavors all at once, setting your tastebuds on an exciting adventure as they try to pick up on each flavor.

*Edit for vegans:

I’ve just been informed that, depending on where you live, not all Guinness is vegan, although the company is in the process of changing their filtering system so that all Guinness will be vegan. Feel free to use your favorite vegan stout in this recipe. If you’re gluten-free, you can use gluten-free beer.

Print This Recipe 5/5


  • 2 tbsp milk of choice (30g)
  • 1 cup Guinness or your favorite stout (240g)
  • 2 tbsp flaxmeal (11g)
  • 1/2 cup plus 3 tbsp olive oil or vegetable or coconut oil (110g)
  • 1 tbsp pure vanilla extract (15g)
  • 1 cup spelt, all-purpose, or Bob’s gf flour (120g)
  • 1 cup unsweetened cocoa or cacao powder (80g)
  • 1/4 tsp plus 1/8 tsp salt
  • 1/2 tsp baking powder
  • 1/2 cup brown sugar or date sugar (115g)
  • only if using Bob’s flour, add 1/4 tsp xanthan gum
  • 1/3 cup stevia baking blend OR regular sugar (you can reduce to 1/4 cup if you have no sweet tooth and are used to healthy desserts)
  • 2/3 cup mini chocolate chips, optional


Guinness Brownies Recipe: Preheat oven to 330F and grease a 9×13 pan. Set aside. In a large mixing bowl, whisk together all liquid ingredients and flaxmeal. In a separate bowl, thoroughly combine all remaining ingredients. Pour wet into dry, stir to combine, and pour into prepared pan. Bake 13-17 minutes (13 for fudge-like brownies, 17 for cakey brownies). Brownies will look underdone when they come out but this is okay! Let cool, then refrigerate overnight and the texture will firm up nicely. DO NOT eat until the next day, as the taste and texture will change while they set.

    I made these brownies yesterday. They are absolutely divine! Maybe even my go-to brownie recipe. Very easy to make and so-so-so delicious! I used all the optional chocolate. As I’m not vegan I didn’t have to worry about the beer, so I used a dark cherry flavoured beer and it resulted in a slight cherry taste. Highly recommended!

    Hello Katie, I just baked your Black Bean Brownies and as you say they are Awesome, moist and chocolaty! However, the brownies are less than 1/2″ high, actually they didn’t rise at all while baking. I followed the recipe exactly and used an 8″X8″ pan with the oven (temp. checked & correct) at 350 degrees. Can you explain or offer any help? Many thanks. We are already addicted to your chocolate chip cupcakes so I think we may be tempting fate to perfect this recipe! Penny

    About the “Guinness isn’t vegan” discussion….according to The Chicago Tribune website and, Guinness Extra Stout brewed in North America does not use isinglass. I made these brownies with it and they were delicious! I am not vegan or even vegetarian but I respect other people’s lifestyle choices so I am glad there’s an alternative.

    Katie, I’m a Guinness girl. Do you have a recipe for this with out sugar with stevia or honey and coconut flour or almond flour instead of the GF flours?

    • Jason Sanford says

      You can definitely sub in extra brown sugar. But do not omit the sugar without subbing in brown sugar, as they would not be sweet enough nor would their texture be correct.

  5. Saz says

    Ummm, think the “quick and easy” in the title is a bit misleading when you then say at the very bottom of the post to NOT eat until the following day. Who wants to make something only to eat it a day later.

  6. Katie says

    I searched around the internet for a vegan beer brownie recipe and they all seemed to call for expensive ingredients.
    This recipe was perfect! It turned out great with a dark lager! Thanks Katie!

  7. Shilpa says

    These were terribly bitter! Assuming that was from the Guinness. Even the beer lovers thought so. I was so embarrassed to have served these.

    • Jason Sanford says

      I’ve made these and never had that problem. Guinness brownies are quite a common thing so adding it to a chocolate recipe should not be bitter unless the beer was bad. Can you tell me more about the other ingredients you used and if you changed the recipe at all, such as cutting back on the sugar or oil or using a different flour?

      • Shilpa says

        Did not make any substitutions and bought the Guinness the same day so I doubt it went bad. I used 1/2 cup brown sugar, 1/3 cup white sugar, all purpose flour, almond milk, and recommended amount of vegetable oil. I also baked for 17 minutes and they still came out fudge-y, not cakey. I tasted the leftover Guinness and am certain this was the reason for the bitterness. Perhaps these are better suited for Guinness lovers.
