Chocolate Guinness Cake that's been sliced into and you can see the layers of chocolate cake, chocolate ganache, and Irish Cream Buttercream against a blue background.

This Chocolate Guinness Cake is made with a rich and tender chocolate cake laced with smooth stout with a chocolate ganache filling and a decadent Irish Cream Frosting!




  • 4 ounces semi-sweet chocolate
  • 4 ounces heavy cream



  • Preheat oven to 350 degrees F and line and grease two 9 or 8-inch round cake pans with parchment paper and cooking spray and set aside. Click for the photo instructions for lining round pans with parchment paper.
  • Combine the sugar, flour, cocoa powder, baking soda, baking powder, and salt in a large bowl or stand mixer fitted with a whisk attachment and mix together.
  • Beat in the eggs, buttermilk, Guinness, oil, and vanilla and beat on medium speed for 2 minutes, the batter is going to be very thin.
  • Evenly divide the batter between the two pans and bake the cakes for 40-45 minutes until toothpick comes clean from center.
  • Cool in pans for at least 10 minutes and loosen from sides of pan before transferring to a cooling rack to cool completely. I like to use Bake Even Strips for a nice and evenly baked cake, but if your cakes dome, you'll need to gently slice the tops of the cake off so they are level before assembling.
  • While the cakes are cooling, prepare the ganache by chopping the chocolate and placing it in a medium bowl. Heat the heavy cream in a small saucepan just until simmering around the edges then pour over the chocolate and let sit for 4 minutes. Once the time has elapsed, whisk until a rich chocolate ganache forms. 
  • Allow the ganache to cool and thicken a bit before spreading on the top of one of the layers of cake about 1/4-inch from the edge of the cake, and set aside.
  • Prepare the Irish Cream Frosting, by creaming the butter in a large bowl or stand mixer fitted with a paddle attachment. Add in the powdered sugar and Irish Cream liqueur a little at a time alternating between each. If frosting seems too stiff, add a little more liqueur.
  • Pipe a line of the frosting around the outer edge of the ganache to seal it in before adding the top layer. Then apply a thin crumb coat of the frosting to the entire cake and place in the fridge for 20 minutes or the freezer for 5 minutes.
  • Use the remaining frosting to finish frosting the cake. Add chocolate sprinkles or other sprinkles as desired.
