Directions
Make the Cupcakes
Preheat oven to 350°F (175°C).
Line a cupcake tin with liners.
In a small saucepan, heat Guinness and butter over medium heat until butter melts.
Remove from heat and whisk in cocoa powder and 2 oz chopped dark chocolate until smooth.
Let cool slightly.
In a large bowl, whisk together flour, sugar, baking soda, and salt.
In another bowl, whisk eggs, sour cream, and vanilla until smooth.
Gradually mix the slightly cooled Guinness mixture into the egg mixture.
Slowly fold in the dry ingredients until just combined. Avoid over-mixing.
Gently stir in the remaining ¾ cup chopped dark chocolate to create pockets of melted chocolate inside the cupcakes.
Fill cupcake liners about ⅔ full.
Bake for 18–22 minutes or until a toothpick inserted in the centre comes out with a few moist crumbs.
Cool completely before frosting.
Make the White Chocolate Ganache Frosting
Heat heavy cream in a small saucepan until just simmering (don’t boil!).
Pour over the white chocolate in a bowl.
Let sit for 2 minutes, then stir until smooth.
Cool to room temperature (about 30 minutes).
Beat butter in a mixing bowl until creamy.
Gradually mix in powdered sugar, salt, and vanilla.
Slowly add the cooled ganache, beating until fluffy.
Chill for 10–15 minutes if it’s too soft to pipe.
Assemble & Decorate
Pipe or spread the frosting onto the cooled cupcakes.
Garnish with dark chocolate shavings, gold sprinkles, or a drizzle of Guinness caramel sauce for extra indulgence.
Serve with a pint of Guinness or a strong espresso.

Why Does Guinness Work in Baking?
Guinness works in baking because its rich, malty flavor and slight bitterness enhance the depth of chocolate, amplifying its taste in recipes like these cupcakes.
The stout’s carbonation acts as a natural leavening agent, contributing to a lighter, more tender crumb in baked goods.
Its acidity also reacts with baking soda, helping the batter rise and creating a moist texture that pairs well with dense ingredients like cocoa and sour cream.
Additionally, the roasted barley in Guinness adds a subtle coffee-like note, complementing dark chocolate and balancing the sweetness of the cake and frosting.
Overall, it brings a unique complexity and moisture to baked goods that water or milk alone can’t replicate.
