Guinness Brownies

Guinness Brownies

Are you looking for a moist and chewy brownie with a rich, dark chocolate taste? If so, I invite you to whip up a batch of Guinness Brownies!

I normally don’t cook with beer, but this month, I stepped outside of my comfort zone and incorporated this secret ingredient into my recipe as part of the Get Your Chef On Cooking Challenge, hosted by Jen from Four Marrs and One Venus and Julie from White Lights On Wednesday.

I incorporated Guinness – a stout beer – into this recipe because the rich flavor found in stouts complements chocolate, making it a popular choice for dessert recipes.

Legend - What Is This

If you prefer dark chocolate to milk chocolate – and less sugary tasting desserts to overly sweet ones – give this recipe a try. Since I could still taste the stout flavor immediately after baking, I preferred letting the flavors settle in for a day or so before eating – then I enjoyed serving brownies warm. Sprinkled with powdered sugar, they make a beautiful presentation!

Guinness Brownies Recipe


1 Cup Whole Wheat Pastry Flour*
3/4 Cup Unsweetened Cocoa Powder
1/4 Teaspoon Salt
5 Tbsp. Unsalted Butter, Cut Into Cubes
8 Oz. Dark Bittersweet Chocolate Bar(s), Chopped
3/4 Cup Milk Chocolate Chips
4 Large Eggs, At Room Temperature
1 Cup Natural Cane Sugar
1 1/4 Cups Guinness Extra Stout Beer, Room Temperature, No Foam
1 Cup Semi-Sweet Chocolate Chips
1/8 Cup Powdered Sugar For Dusting

*Note: If you don’t have Whole Wheat Pastry Flour on hand, use this substitution:

Pastry Flour = 1/3 Cup Cake Flour Plus 2/3 Cups All Purpose Flour


1. Preheat the oven to 375° and grease a 9 x 13 baking pan.

2. Whisk the flour, cocoa powder and salt together.

    Hey Joy,

    Thanks for this. The brownies sure do look good. I’m wondering if there is an alternative to beer that might give a similar flavor? I don’t drink beer – but they do look fantastic!

    Thanks so much for the recipe!

    • Hi Lisa,

      I did a little research and came across a few suggestions, including red wine and water, as alternatives. I’m not a beer drinker either – my husband had to purchase this for me just for the challenge!

      For the record, he purchased 2 bottles just in case we needed them, but we only ended up using 1 for the recipe. He ended up giving the 2nd bottle away to an appreciative friend!

      Have a great day!

  2. Stopping by from Get Your Chef On~ What a great recipe:) So much fun checking out all the Beer recipes! Have a Great Week~ Lynn @ Turnips 2 Tangerines

  3. Paula says:

    wow! looks yummy. Pinned (and making!)

  4. Love the brownies. I have stout left over and I like using whole wheat flour, so this recipe is on my Easter brunch menu.

    Thanks so much for sharing,
    Joanne (#14)

    • Awesome – I hope your family enjoys them!
      I don’t normally think of brownies as an elegant dessert, but I was really impressed at how lovely a contrast the dark brownies and the powdered sugar – and the “cake cut” – made! 🙂

  5. I bet the guiness makes the brownies taste really rich. I never have guinness in the house because we aren’t really dark beer drinkers…but if I ever come across a bottle I am going to give this recipe a try!

  6. Tereasa says:

    Now, I never would have thought of adding beer to brownies, but you made it sound incredible!

  7. JP @ A Quiet Corner says:

    These look delightful! Although I am not a beer baker either, I may have to see if the Pres will drink it if I buy it!….:)JP

  8. Melanie Goad says:

    I LOVE guiness and I LOVE brownies. I’m pinning this baby.

  9. Beer in brownies??? I never would have put those two together but they look amazing! Thanks for sharing!

  10. Tracey M says:

    Wow, did this recipe catch my eye! I’ve never heard of this combination before. I happen to love Guinness, it’s one of my favorites. I’ve used it in a stew, but never heard of it in baking goods before. Will have to try this one! I’ll be sharing this on my FB page too 🙂 (Love the photo of your kitty with the Guinness too.)

  11. Thanks for the heads up about the taste. If I made them I’d have to let them set and marry as I am not a beer drinker. They do look tasty though.
    Thanks for sharing with us at “In and Out of the Kitchen Link Up Party”

    I had really not thought about using beer in so many recipes, my son would like it if I bought Guinness to use, Im sure he would take care of the leftovers! Not to mention the brownies look awesome and I like that they would not be so sweet!! Thanks for adding this link to the Tasty Tuesday Spots!! Have a great day!

  35. Laurie says:

    Well…these look very rich. I’ve never tried stout and probably never will, so I’ll just have to take your word that the flavors complement each other. I prefer a dark chocolate.

    Thanks for sharing your recipe at the Sunday Sunshine Blog Hop!
