Chocolate Guinness Cupcake Recipe

Cook Time30 mins
Author: Sarah Sibley


  • 100 g Self Raising Flour
  • 50 g Cocoa Powder
  • 200 g Caster Sugar
  • 115 g Butter Stork
  • 1 x Egg
  • 115 ml Guinness / Stout
  • 75 g / 75ml Buttermilk
  • 200 g Softened Unsalted Butter
  • 400 g Icing Sugar
  • 4 tsp Milk


  • Pre-heat the oven to 325° F / 160° C / 140° Fan / Gas 3
  • Line a muffin tray with 12 large black muffin cases
  • Place the flour, cocoa & sugar in a large bowl and mix together
  • In a separate bowl melt the butter (1min in the microwave should be fine)
  • Add the egg and mix thoroughly
  • Next add the Guinness and mix again
  • Then add the buttermilk and mix. It will look like a curdled mess at this point, but that's fine!
  • Make a well in the dry ingredients and add some of the liquid
  • Mix it in with a spatula or wooden spoon
  • Add some more and again mix it in
  • Then finally add the rest of the liquid and mix to a smooth batter
  • Carefully spoon the mixture into the cases
  • Bake for around 30mins or until a cocktail stick comes out clean
  • Transfer to a wire rack to cool
  • For the frosting, mix the softened butter and vanilla in a large bowl
  • Add the sifted icing sugar and start to mix
  • Then add the milk and continue to mix until you have a smooth frosting
