I really don’t know how to describe this cake to you other than to say that this is the best tasting cake I’ve ever eaten! How’s that for a recommendation? To help celebrate St. Patrick’s Day you can use that good Irish Guinness beer to plain ol’ drink, make into some Guinness braised short ribs or for the best use you will make this Guinness cake. Did I mention it’s Guinness CHOCOLATE cake? And just to give it a little more Irish joie di vivre there’s some Irish whiskey in there too. Erin go braugh!

If you gave up chocolate or booze for Lent, you are seriously shit outta luck on this one. Although, isn’t there some kind of exception rule in the Catholic church if St. Patrick’s day happens during Lent? Forgive me for being stupid on this, but it’s been a long time since I donned my old Catholic school girl uniform. I think it was Halloween 1992 when I last wore it. It’s now packed away somewhere at my parents house.

Guinness Cake for a great St Patricks Day Recipe

You’re also pretty screwed if you’re doing some kind of sea kelp cleanse, the maple syrup and cayenne pepper detox and/or eschewing all white foods (for whatever reason…be it sane or insane). But if you’re on the see food diet…you’re all good. This Guinness cake is ENORMOUS! Trust me when I say these pictures don’t do it justice. It’s full of butter, flour, sugar, Guinness beer and a touch of Irish whiskey (just to stay in the theme of the day).

I realize that this is not my normal type of posting, but I was informed that I would lose my food blogger status if I didn’t post a St Patricks Day recipe. And, to be fair…I thought I needed to post up a Guinness recipe this time because last year I posted a mint chocolate brownies recipe that didn’t use Guinness, and used a (GASP) boxed brownie mix (pure blasphemy…I know – whatever). They’re really good…so if you haven’t made them, you’re really missing out. But don’t make those before you make this Guinness chocolate cake.

Guinness Recipe

I make no claims that any part of this recipe is mine. The Guinness cake recipe comes from an old issue of Bon Appetit. The frosting, which is Italian meringue (and my new favorite recipe) is a Julia Childs recipe. I did bastardize modify it a touch by replacing some of the water with whiskey (I think Julia would be proud). And the chocolate ganache recipe is one that I’ve used in numerous recipes here on the site. I will claim, however, that the original recipe called for the cake to be coated in just chocolate ganache. I wanted to introduce a bit more Irish in it with the addition of whiskey (why just make a plain Guinness cake when you can make a Whiskey Guinness cake?) and thought the Italian meringue would be a tasty delivery vehicle for said booze. Plus it adds a nice touch of contrast, don’t you think?

So get baking and don’t skimp on the quality of your ingredients. The better the chocolate and butter, the richer the flavor. The actual whiskey you use is up to you. I used Bushmill’s whiskey because firstly, it’s Irish and secondly, I had it on hand.

What is your favorite St Patricks Day recipe? And yes, you can say making reservations or hitting your favorite Irish pub on the 17th. Those both count in my book.

YES – I SEE HOW LONG THE INSTRUCTIONS LOOK ON THIS RECIPE – DO.NOT.FREAK.OUT. The reason they seem so long is because there are actually 3 recipes that make up this cake. Also, I gave some really basic instructions on how to frost the cake. I understand that most people know how to frost a cake, but some don’t. To save those people lots of frustration (and having to make 2 batches of Italian meringue to frost their cake) I opted to give some helpful instruction. Most of you can skip the “How to Frost the Cake” set of instructions.

Prep time
Cook time
Total time
This Guinness cake is full of so much chocolatey boozy goodness you'll be grinning for days.
Recipe type: Dessert
Cuisine: American
Serves: 12
  • For the Cake
  • 2 Cups Guinness Stout
  • 4 Sticks Unsalted Butter (2 cups)
  • 1½ Cups Unsweetened Cocoa Powder (best if you use Dutch Process)
  • 4 Cups Flour
  • 4 Cups Sugar
  • 1 Tablespoon Baking Soda
  • 1½ Teaspoons Salt
  • 4 Large Eggs
  • 1⅓ Cups Sour Cream
  • For the Italian Meringue
  • ⅔ Cup Egg Whites (4 to 5 whites)
  • Pinch of Salt
  • ¼ Teaspoon Cream of Tartar
  • 1⅓ Cups Sugar
  • ¼ Cup + 1 Tablespoon Water
  • 3 Tablespoons Irish Whiskey
  • For Chocolate Ganache
  • 1 Cup Heavy Whipping Cream
  • 1½ Cups Dark Chocolate (not to exceed 72% cocoa)

  1. For the Cake
  2. Preheat oven to 350 degrees Farenheit.
  3. Butter 2 9 inch round cake pans (or original recipe calls for three 8-inch round cake pans) with 2 inch high sides.
  4. Line the bottom with parchment paper and butter the parchment paper as well. (Make sure that the part where the sides meet the bottom are well buttered so that the cake doesn't stick there.)
  5. Add 2 cups of Guinness, and the butter to a large saucepan and bring to a simmer over medium heat.
  6. Once simmering, gradually whisk in the cocoa powder (add the cocoa in thirds to help keep it from clumping up.
  7. Remove from heat and let cool a bit.
  8. In a large bowl whisk flour, sugar, baking soda, and 1½ teaspoons salt to make sure everything is blended well.
  9. In the mixer, beat eggs and sour cream until they just come together.
  10. Add the warm stout mixture to the egg mixture and beat until just combined.
  11. Add flour mixture (in fourths) and beat briefly on slow speed until just barely combined. (This makes A LOT of batter.)
  12. Use a spatula and fold the batter until everything is completely combined.
  13. Divide batter equally among prepared pans.
  14. Bake cakes until tester inserted into center of cakes comes out clean, about 35 minutes (mine, in the 9 inch pans took almost 50 minutes).
  15. Let cakes cool for 10 minutes, while resting on top of cake racks, then turn the cakes out onto the racks and let cool completely. (I let mine rest overnight.)

  16. For the Italian Meringue
  17. Beat the egg whites at slow speed until they foam throughout the bowl.
  18. Add the salt and cream of tartar.
  19. Gradually increase the mixer speed and beat until soft peaks form.
  20. Turn the mixer speed down to 'slow' as you make the sugar syrup.
  21. Bring the sugar, water and whiskey to a simmer in a heavy saucepan.
  22. Swirl the pan to dissolve the sugar completely.
  23. Using a candy thermometer, bring the temperature to 234 - 240 degrees Farenheit (soft ball stage). Do not stir the mixture.
  24. While the mixer is still on slow, slowly (and carefully) pour the boiling syrup down the side of the mixing bowl (be careful not to pour it on the whisk).
  25. Increase the mixer speed to moderately fast and beat until cool and the egg whites form stiff, shiny peaks.
  26. You are now ready to frost the cake.
  27. For Chocolate Ganache
  28. Finely chop the chocolate and dump into a large, heat resistant bowl.
  29. Heat the cream, in small heavy saucepan, over medium heat until bubbles begin to form around the edges.
  30. Pour half of the cream over the chocolate and let sit for 30 seconds.
  31. Whisk the chocolate and cream mixture until you see that the chocolate is being mixed with the cream.
  32. Pour in the rest of the warm cream.
  33. Continue whisking until all of the chocolate has melted.
  34. Set chocolate ganache aside.

  35. Frosting the Cake
  36. Determine how many layers you want your cake to be.
  37. Cut your cakes into the number of layers you would like.
  38. Make sure that your cake layers are even. If not, cut them with a serrated knife to make them even.
  39. Set the first layer of cake onto your cake plate.
  40. To make the cake plate clean, cut 4 strips of parchment paper and arrange part of them under the cake and rest on the cake plate. When you're done icing the cake, you just carefully pull them away and your cake plate is nice and clean.
  41. Spoon about ¾ cup of the meringue onto the first layer (this is what I used for 4 layers on a 9 inch cake).
  42. Smooth meringue into an even layer and leave about ½ inch all around that layer without meringue (when you add the next layer, the meringue will work its way out to the edge).
  43. Continue doing this on the rest of the layers.
  44. Once you get to the top layer, you can use more of the meringue.
  45. I smoothed the top layer of meringue to give a better surface for the ganache.
  46. As you work down the sides of the cake, with the meringue, you can make a smooth or rough finish. (I went with rough on my cake.)
  47. Check the temperature of your ganache. You don't want it too hot or too cold.
  48. Re-whisk the ganache and pour it into a pitcher or measuring cup with a spout (makes pouring easier).
  49. Carefully pour the ganache in a circle on the top layer of the cake. Start in the center of the cake and work your way to the edge. (Don't use all of the ganache.)
  50. Now smooth the ganache with an offset spatula. Again, start in the center and work your way out.
  51. As you get closer to the edge, you'll push the excess over the sides and form the drips.
  52. Use the leftover gananche to pour more on top and gently push the excess over the edge to form more drips.
  53. Let stand for a couple of hours so that the ganache has time to set up.
I used 2 9 inch pans, each filled half way, and had enough batter left over to make 6 really nice cupcakes. You could also use this recipe and just make cupcakes with it. You should get about 24 cupcakes (possibly 30).

So my cake is slipping and sliding any suggestions??

Pamela March 15, 2017 at 3:36 pm

Hi Nicole, You could cut wooden skewers to the height of your cake and insert 4 of them (in the shape of a square) into your cake. Just remember that they’re in there when you go to serve it.

Thanks for sharing this great recipe and notes! I am making for a St. Paddy’s gathering coming up and it needs to feed approx. 35+ lads and laddies. So, I upped it to 1-1/2 times (3 cups stout, 6 cups folur/sugar, etc.) and baked on 3 large sheet pans for 20-22 minutes each. Came out perfectly! Now chilling for “stage two” – the meringue – which I will add a “wee bit ‘o green” coloring to appease the leprechauns. Then I will trade out that yummy ganache (which I love) with a Bailey’s Irish Cream frosting and use the ganache to makes cake topping decorations. (May need a liquor license to serve!) Just thought I’d add this comment as it pertains to pans and cooking size. These 3 layers with filling and frosting will definitely and amply feed the Irish crowd with corned beef and cabbage-filled bellies. (As long as I quit tasting all the yummy batter and crumbs!) Thanks & a pot ‘o gold at the end of the rainbow to you!

Robin, I’m coming to your house for dinner!!!!!! Your cake version sounds divine. 🙂

Wendy February 13, 2015 at 9:35 am

I’d like to make this cake for a neighborhood St. Patrick’s day party but my 9″ pans are not 2″ high… they are just over 1.25″ high so my question is, does this cake raises a lot? I just want to make sure I leave enough room at the top if it does.

Pamela February 13, 2015 at 9:50 am

Hi Wendy, the cake does rise quite a bit. I’d fill your pans half way, then bake. You’ll end up with 3-4 layers without having to go through the torture that is trying to cut cakes in half. LOL (or maybe that’s just my torture) #manyalopsidedcakeinmykitchen

amallia March 24, 2013 at 12:57 am

Can I have a piece of the cake please……..:)

Pamela March 17, 2013 at 7:18 pm

Jenni, you.are.a.rockstar! That’s the same kind of thing I do when a part of a recipe doesn’t quite come out like it should. I’ll bet those cupcakes filled with that Jameson meringue were AMAZING! Hostess who? Thanks for letting us know how it worked. 🙂

Jenni C March 17, 2013 at 6:49 pm

Ahh..I screwed up the cake. I cooked the cake too long. I didn’t want to go through all of that again, lol, so I just used a box of Devil’s Food Cake and subbed the Water for Guinness. It came out delicious. I did however follow the instructions for everything else. I made them into cupcakes also. They were a HUGE hit, and everyone LOVED the creamy Jameson centers.

I saw this on Pinterest. So glad I found your blog. Love your sense of humor, and I often say the same thing as your blog name. I seduced my husband with massage (my former profession) and my cooking. Since we got married, he gets a lot of cooking, but no more massages. Ha! I love to bake, and have always wanted to make an Italian meringue. Yes, this makes for a beautiful contrast, and breaks up the chocolate factor just right. Repinning on my own board, so I can make this. I’m looking for a dessert for tonight, and debating if I can pull it off in a few hours. It would certainly make a statement!

Pamela March 16, 2013 at 10:50 am

Thanks for the kind words. 🙂

I get the massage thing. After we got married, Craig stopped massaging my feet and cleaning up after himself (which was a MAJOR turn on for me). ARGH!

Don’t let the length of instructions deter you from making it. Everything actually comes together really quickly and the directions are pretty easy. (That Italian meringue was a lot easier to make than I had thought it would be.) As long as you can get the cake cooled down in time, it’s a dessert than can definitely be made in a few hours. By not smoothing the meringue, and letting it be all rough, you’ll save a ton of time putting it together. ENJOY!

Emanuelle March 12, 2013 at 5:31 pm

Looks unbelievably good!!!

Pamela March 12, 2013 at 5:36 pm

Thanks Emanuelle, it tastes even better than it looks. ENJOY!

Jenni C March 10, 2013 at 11:56 am

So glad I found this! My fiance’s bday is the day after St. Patrick’s Day and it’s also his favorite holiday of the year. He is Irish and is very into his heritage. I’m totally making this to go with his favorite dinner of Corned Beef, Cabbage and Potatoes. I’ve also signed up to your blog..can’t wait to see more great recipes!

Pamela March 10, 2013 at 12:16 pm

Hi Jenni,

You are going to LOVE this cake…so is your fiance. 😉 Sounds like you are having the ultimate St. Paddy’s day spread! Thanks for signing up to the blog. I think you’re going to really like the things I have coming up. ENJOY!

Kat March 8, 2013 at 7:08 pm

You will be pleased to know that during lent you are allowed to ditch your lenten fast (chocolate or liquor or whatever you gave up) on Sundays and major feast days 😉 Seeing as St Patty’s this year is BOTH, well, eat all the amazing looking choco whiskey cake you like 😀

Pamela March 8, 2013 at 7:10 pm

Hi Kat,

I did really think there was some kind of dispensation regarding St. Patrick’s day. But I had NO idea about getting Sunday’s off. I hope you get your fill of this cake next Sunday. ENJOY! 🙂

Belinda @zomppa March 8, 2013 at 6:09 pm

I’m sorry, but I could barely read your post. Why? Because my eyes just kept focusing on that CAKE!!

Pamela March 8, 2013 at 6:14 pm

Thanks Belinda,

You are totally excused from reading. LOL (I completely understand.) You should have seen me staring at that cake in my kitchen. I couldn’t believe I had made that monstrous dessert.Thankfully, I had lots of willing bellies to share it or I would have been writing this from the hospital after suffering an enormous food coma. 😉
