Guinness Brownies Recipe

Bow down to all that is rich chocolaty goodness. I came across this recipe for Guinness Brownies a few months back, but this is the first opportunity I’ve had to try it out.

They have a slightly different texture and taste to normal brownies, but by god do they taste good!

The only recipe I can find uses US measurements. I converted as much as I could and the recipe I’ve posted here is the metric version I worked out while making them. I ended up using quite a different assortment of chocolate as I didn’t have enough of one kind. The original recipe says to put 3/4 cup of cocoa which is far too much (is cocoa different in the US compared to here?) Next time I may add a bit more flour to give a drier texture.

  • 2 tsp cocoa
  • 290ml Guinness
  • icing sugar


1) Preheat oven to 190oc and line 8 inch square baking pan with baking parchment.

2) Combine eggs and sugar. On a medium heat melt chocolate and butter until smooth. Allow to cool for about 3 mins.

3) Beat chocolate mix into egg mix. Sift in flour and cocoa. Beat until well combined.

4) Whisk in Guinness, then pour into pan. Bake for 25 min until a skewer comes out just abour clean. It will continue to cook slightly after being taken out of oven.
