Boozy Irish Cake

"This delicious and moist cake mimics the famous drop-a-shot-into-a-pint flavors: Guinness®, Baileys®, and Jameson®. The whiskey is the dominant flavor. The amount can always be reduced and substituted with water. Additionally, heavy cream can replace the Baileys® in the frosting."

  1. Preheat oven to 350 degrees F (175 degrees C). Grease and flour 2 9-inch cake pans.
  2. Place the cake mix into a large mixing bowl. Pour the water into a 2-cup measure, and add enough Irish whiskey to total 1 1/3 cup of liquid (about 10 1/2 tablespoons). Reserve remaining whiskey. Beat the whiskey and water mixture, vegetable oil, and eggs with an electric mixer on low speed just until cake mix is moistened; increase speed to medium, and beat until the batter is smooth, about 2 minutes. Pour batter into the prepared cake pans.
  3. Bake in the preheated oven until the cakes are golden brown and a toothpick inserted into the center of a cake comes out clean, 25 to 30 minutes.
  4. While the cake is baking, pour remaining Irish whiskey (about 1 1/2 tablespoon) into a saucepan, and stir in 1/4 cup of butter and 1/2 cup of sugar. Bring the mixture to a boil, stirring constantly, until sugar has dissolved; boil until slightly thickened, about 5 minutes.
  5. When cakes are done baking but still hot, poke holes all over the cakes (the end of a chopstick works well for this) and drizzle the whiskey syrup into the holes. Return the cakes to the oven, and bake for an additional 5 minutes.
  6. Remove cakes from oven, allow to cool in pans for 15 minutes, then remove from pans to finish cooling on wire racks.
  7. To make caramel sauce, mix the Irish stout beer with 1/2 cup of sugar in a saucepan over low heat. Simmer the mixture until thickened, about 40 minutes, stirring occasionally, and allow to cool.
  8. To make frosting, beat 1 cup of softened butter in a bowl with an electric mixer on medium speed until smooth, then gradually beat in confectioners' sugar, about 1/2 cup at a time. Beat in salt, then add the Irish cream liqueur, beating until the frosting is light and fluffy.
  9. To assemble the cake, place a layer onto a cake serving dish; pour the Irish stout caramel over the first layer, allowing the caramel to drip down the sides of the layer. Place the 2nd cake layer on top, and top with the buttercream, swirling the frosting into decorative waves. Do not frost sides of cake.

1 1/2 Tablespoons of liquid is not enough to dissolve 1/2 cup sugar into (butter will not dissolve sugar) After following the recipe as it is posted here I ended up with a seized-up sugar-butter-whiskey mass and had to do the syrup part over with changes. My recommendation is to make the cake according to the directions on the box without adding whiskey to the water. Then make the syrup by mixing 1/2 cup whiskey and 1/2 cup sugar stirring to dissolve sugar. Bring to a boil, reduce heat to medium and cook 5 minutes. 1 or 2 Tablespoons butter can then be added, stir until butter melts. Gently apply the syrup over the warm cake layers with a pastry brush until all the syrup is used or poke the cakes all over with a skewer and drizzle the syrup . To me, a whole cup of butter in the frosting is excessive. 1/2 cup is plenty.


This cake is delicious but really time consuming. For those having trouble with the beer caramelizing, it needs a touch more sugar and it has to be cooked at a high heat. Next time I will use a little less sugar in the frosting because it was really really sweet. Everyone loved this. I was prepared to hate it and liked it too.


I had a really hard time with the stout caramel reducing to an actual working consistency, so instead I just drizzled it like the whiskey butter sauce. Also, I added a lot more baileys to my frosting, almost another half cup... It was a lot tastier! I brought them to a party and everyone thought they were to die for! Thank you
