Irish Car Bomb 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."

Directions

Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.

  1. Heat the oven to 350°F (175°C). Grease two 9-inch round cake pans with a little of the vegetable oil.

  2. Combine the stout beer, 1/4 cup butter and the first 1/2 cup white sugar in a saucepan over medium heat. Simmer until reduced by about half, then let it cool.

  3. In a large bowl, beat the cake mix, water, remaining vegetable oil, eggs, 3/8 cup of the Irish whiskey and the cooled stout mixture until smooth, about 2 minutes.

  4. Divide the batter evenly between the pans. Bake 25 to 30 minutes, until a toothpick inserted in the centers comes out clean.

  5. Cool the layers in the pans for 10 minutes, then turn them out onto a rack to cool further.

  6. Heat the remaining 3/8 cup Irish whiskey with the second 1/2 cup white sugar, stirring until the sugar dissolves. Brush this syrup over the cooled layers.

  7. Beat the softened butter, confectioners' sugar and salt until light and fluffy. Beat in the Irish cream liqueur until smooth.

  8. Place one cake layer on a plate, spread with frosting, top with the second layer and frost the top and sides.
