I was honoured when asked to bake the birthday cake for a friend's party. I had just the thing for it too! Having just made Smoked Chocolate, I knew that I had to use it in this cake. The cake was a huge hit... it was also huge. I doubled this recipe for a two layer cake. I put a fudge-y chocolate layer in the middle and topped it all off with a marshmallow and cream cheese frosting. The recipe here makes one 9-inch, single layer cake. You will need a kitchen scale to weight out the chocolate.

Pretty cake!

Smoked Chocolate Guinness Cake

Serves: 8       Total Time: 65


  • 1 cup + 3 tbsp. unsalted butter
  • 1 cup packed, dark brown sugar
  • 100 g Smoked Chocolate, melted
  • 2 large eggs
  • ¾ cup + 2 tbsp. Guinness
  • 2¼ cups flour
  • ¼ cup of cocoa
  • 1 tsp. baking powder
  • 1 tsp. baking soda
  • 12 Fudgeo or  Oreo cookies
  • 1 tbsp. butter, melted
  • 1½ cups icing sugar
  • 1 tbsp. cocoa powder
  • 1 to 2 tbsp. milk
Marshmallow Cream Cheese Icing
  • 1 8oz. block of cream cheese
  • 1 7½oz. jar of fluff marshmallow spread
  • 1 tsp. vanilla extract


Step 1
Preheat your grill (or oven) to 320°F. Grease a 9-inch cake pan.
Step 2
Melt the Smoked Chocolate over a double boiler, on medium-low heat with the 3 tbsp. of butter. Be careful not to let the chocolate scorch, or over heat, it will get grainy. If it goes grainy, lower the heat a little and add more butter.
Step 3
Beat the sugar and 1 cup of butter until light and fluffy, about 2 minutes. Gradually beat in the melted chocolate. Then add the eggs, beating them in one at a time. Gradually whisk in the Guinness.
Step 4
In a separate bowl, sift together the dry ingredients, then fold them gently into the batter, it will resemble the lightest mousse you have ever seen at this point.
Step 5
Pour the batter into the prepared cake pan (or cupcake tin if you like). Bake over indirect heat for 35 to 45 minutes, or until a cake tester comes out clean.
Step 6
Allow the cake to cool in the tin, then turn it out onto a cake plate.
Step 7
If you want to do a small layered cake, slice the cake in half horizontally. Or double the recipe to make a two tiered cake.
Step 8
Break the cookies into small chunks, but do not let them become dust. You want them recognizable as cookie bits
Step 9
In a small bowl combine the icing sugar, the cocoa and the crumbled cookies.
Step 10
Mix in the melted butter. Add the milk, one tbsp. at a time until you have a thick paste.
Step 11
Spread this between two layers of cake.
Step 12
In a large bowl, allow the cream cheese to come to room temperature.
Step 13
Beat in vanilla until smooth. Add the whole jar of Fluff and beat with a hand mixer until the mixture is smooth. Spread over your cake.
These beautiful photos of the cake were graciously done by my friend Kelly. I can’t thank her enough for stepping up to the plate! I totally forgot to bring the camera in all the party excitement.

Happy Grilling!
