Excusing the stereotyping that may or may not occur in this particular episode we can promise that the cake is divine! Rich, heavy chocolate cake with a hint of Guinness and a gorgeous Guinness frosting that'll have you running for the end of the rainbow!
Preheat the oven to 350°F (180°C).2.
Melt the Butter and Guinness: Melt the butter in a pan along with the Guinness. Beat in the brown sugar, sunflower oil and cocoa powder until smooth and lump free.3.
Finish the Cake Mixture: Mix the eggs with the yogurt in another bowl. Whisk in the chocolate and Guinness mixture. Fold in the flour and baking powder.4.
Divide and Bake: Divide between 4 half pint Guinness glasses so they are three-quarters full, allowing for a rise and frosting. Bake for 40 minutes until risen and cooked through (test with a skewer in the center of each). Allow to cool fully.5.
Level the Cake: Level off the top of the cake where it may have risen unevenly and blitz the cake pieces up to a crumb and wedge back into the gaps in the glass.6.
Make the Frosting: Dump all the frosting ingredients (cream cheese, icing sugar and 25 ml Guiness) into a bowl and beat until smooth and fluffy. Spoon the frosting onto the top of each cake to look like head on a pint. Garnish with a shamrock made from fondant icing or mint leaves.
