The Ultimate Guinness Chocolate Brownies
If you want a dessert that is fudgy, rich, and unapologetically indulgent, these Guinness Chocolate Brownies deliver. Inspired by the classic Guinness cake, this version is baked as a dense brownie and finished with a thick cream cheese frosting that looks just like the head on a freshly poured pint.
It’s simple, bold, and incredibly satisfying.
How To Make Guinness Brownies
Ingredients
This recipe uses straightforward measurements that make it easy to remember and repeat.
Brownie base
- 300g golden caster sugar
- 300g butter
- 3 large eggs
- 150ml Guinness
- 200g chocolate
- Flour (as used in the method)
Cream cheese frosting (“pint head”)
- 225g butter (room temperature)
- 225g caster sugar
- 225g cream cheese
Method
1. Make the brownie batter
- Cream the 300g butter and 300g golden caster sugar together until smooth.
- Add the eggs one at a time, beating well after each addition.
- If the mixture looks like it’s splitting, add a small spoon of flour and continue mixing.
- Pour in the 150ml Guinness, add the 200g chocolate and flour, then mix until fully combined.
2. Bake
- Line a tin with parchment paper.
- Pour in the batter and bake at 170°C for 35–45 minutes.
3. Make the frosting
- Beat the butter and caster sugar together until very pale and fluffy.
- Add the cream cheese and mix until smooth.
- If the frosting becomes too soft, place it in the fridge to firm up slightly.
4. Assemble
- Allow the brownies to cool for 20–30 minutes before frosting.
- Spread the frosting thickly over the brownies, creating gentle peaks so it resembles the head of a Guinness.
- Slice into squares and serve.
Tips for best results
- Adding eggs slowly keeps the batter smooth.
- Let the brownies cool fully before frosting or it will melt.
- A chilled frosting spreads more cleanly and holds its shape better.
Final thought
These brownies are rich, striking, and deeply chocolatey, with just enough Guinness flavour to give them depth. If you love the look of a pint of stout and want that feeling in dessert form, this recipe is a winner.
