Subtlety has never been one of my strongest qualities. Case in point: today’s Flourless Whiskey Cake. The intensity of the chocolate and booze that’s jammed into this eight-inch, chocolate ganche-topped circle of fudgy euphoria is anything but indirect.

I blame my Irish heritage for my inability to understate. I met one of my best friends in college because I was chatting too loudly to the girl beside me, and he turned to me and said, with no subtlety of his own, “Will you be quiet so the rest of us can hear already?”

As it turns out, he is Irish too. Also, I was under the impression that I was whispering—I was not.

This “Irish whisper” of mine has followed me into adulthood, where I regularly speak at inappropriate volumes, while believing that I am using normal tones. It’s a work in progress. If someday you catch me in a restaurant waxing poetically about the dessert in an explosive manner typically reserved for campaign speeches, feel free to tell me to pipe down. I’ll probably thank you.

About This Fudgy Flourless Chocolate Cake

Flourless chocolate whiskey cake is not the sort of dessert that lends itself to quiet appreciation. Do you like your chocolate and whiskey to be loud and proud? We are long-lost, Irish-whispering twins. I baked this whiskey cake just for you.

And that whiskey chocolate ganache I spread all over the top? That’s for you too.

This flourless chocolate cake with chocolate ganache is the sort of indulgent dessert that will cause you to lean back in your chair, close your eyes, and utter a three-way combination of, “MMMMMMM,” “YAAAASSSSSS,” and “WHOOOOAAA.” I’ll let your imagination put that together, but know this: you will not say it in a whisper.

An incredible flourless chocolate whiskey cake. Rich, dense, and so easy to make! @wellplated

Flourless chocolate whiskey cake is not a hushed dessert for ladies in white gloves. It’s a boisterous, fudgy, and chocolate-ganache-topped bash for serious chocolate (and whiskey) lovers.

Since I added Irish whiskey to the flourless chocolate cake and to the chocolate ganache, I felt it only appropriate to take the Irish reference a step further by adding a sprinkle-shaped shamrock too. It’s super easy to do, even for the least-crafy among us (myself included). You’ll find complete directions to make the sprinkle shamrock in the recipe, and I even made you a free printable shamrock stencil that you can download and use to make your own shamrock chocolate whiskey cake here!

Flourless Whiskey Cake

5 from 1 vote
A decadent flourless chocolate whiskey cake topped with chocolate ganache. Rich and delicious, everyone loves it, and it's gluten free!

Prep: 20 mins
Cook: 20 mins

Servings: 1 9-inch cake (12 slices)


For the whiskey cake:

  • 7 ounces dark chocolate or semisweet chocolate, coarsely chopped*
  • 10 tablespoons unsalted butter (5 ounces) cut into pieces
  • 1/2 cup granulated sugar plus 2 tablespoons
  • 1/4 teaspoon salt
  • 5 large eggs at room temperature
  • 1/2 cup unsweetened cocoa powder plus 2 tablespoons
  • 1 1/2 teaspoons pure vanilla extract
  • 1/3 cup Irish whiskey Jameson is my favorite, although 2 Gingers—what you see in the photos—is also good, and a bit less expensive; if you like, you swap and whiskey, bourbon, or even rum you prefer. To make the cake non-alcoholic, use brewed, cooled coffee

For the whiskey chocolate ganache:

  • 4 ounces dark chocolate or semisweet chocolate, coarsely chopped (about 2/3 cup)
  • 2 tablespoons unsalted butter
  • 1 tablespoon  Irish whiskey see notes in ingredient list above for whiskey brands, or substitute brewed, cooled coffee
  • 1/8 teaspoon kosher salt

If making the shamrock outline:


  • Place a rack in the center of your oven and preheat the oven to 375 degrees F. Grease an 9-inch round cake pan, line the bottom with a circle of parchment paper, then grease again. Set aside.
  • In a large heatproof mixing bowl set over a pan of simmering water (or in a microwave-safe bowl in 15-second bursts), melt together the chocolate and butter. When the chocolate is almost completely melted, remove from the heat and stir until completely melted and smooth. With a mixer on medium low speed, slowly add the sugar and salt and mix until smooth. Mix in each egg one at a time on medium low speed. Completely combine between each addition and stop to scrape down the sides of the bowl as needed. Sift the cocoa powder into the bowl, then add the vanilla extract and whiskey. Mix on low speed until well combined. The batter will be thick, smooth, and glossy.
  • Scrape the batter into the prepared pan, smooth the top, and bake for 18-22 minutes, until a toothpick inserted into the center comes out mostly clean with just a few crumbs clinging to it. (Do not overbake or the cake will become dry!) Allow cake to cool in pan for 5 minutes, run a butter knife around the edge, then gently invert the cake onto a serving plate.
  • While the cake cools, prepare the chocolate ganache. In a small saucepan or a microwave-safe bowl, melt together the chocolate and butter until just a few pieces of chocolate and butter remain. Remove from the heat, then continue stirring until the two are completely melted and smooth. Stir in the whiskey and salt, then spread over the cooled cake.
  • To make the sprinkle shamrock: While the ganache is still wet, lightly place the shamrock cut out on the cake's surface in the center. With a toothpick or the point of a sharp knife, lightly trace around the shape so that you leave a faint outline in the glaze. Carefully life off the cut out. Fill in with colored sprinkles. For clean slicing, refrigerate the cake for a few hours. For immediate (messy) slicing, dive in right away.


Because this cake has so few ingredients, the quality of chocolate that you choose is ultra important, so be sure to pick a good brand.

  1. I’m not a bit Irish, but I can definitely imagine that my exuberance about a cake like this would be anything but quiet! This looks irresistibly fudgy, and I love the shamrock on top, too!

  2. This cake is so cute, and the flavors of whiskey and chocolate sound so bold and delicious! This is so cute for St. Patty’s Day too, love that shamrock!

  3. hey girl- This looks oh so yummy! We have to be related because…… my Dad is just like you! He can’t whisper either (Ha,Ha) My Mom is always telling him to quiet it down! Crazy! 

  4. im not irish but im loud…my boyfriend has to remind me to calm down sometimes..opps 
    i dont have whiskey on hand but i could see myself do this with coffee soon! 

  5. Is it really ganache if there is no cream used to make it?
    I am wondering if there is a typo there somewhere.
    I have made the Flourless Chocolate Torte and am looking for the ganache recipe you linked to it. Thanks!

    1. Hi Jessica! I’ve hard ganache called a few different things, but if what you are looking for is an intensely rich and chocolaty topping, this will do the trick :)

    1. Hi Toni! It’s been a while, so I honestly can’t remember. I love Trader Joe’s pound plus dark chocolate bar, and Lindt is also delicious. I hope you enjoy the cake if you try it!
