Start preparing your coffee and heating it up low heat with the coffee and a tablespoon of sugar and let it cool. You can skip this step if you prefer to soak your ladyfingers in stout beer without coffee.
Separate the egg whites and yolks. We will use the yolks in the recipe.
Beat the egg yolks with the sugar until you have a creamy texture, you can use a whisk to help you.
Soft your mascarpone cheese with a fork and whisk it with the cream, low speed. You will have a creamy texture similar to whipped cream.
With the help of a spatula incorporate the egg yolks to the mascarpone cheese cream.
Soak the ladyfingers or savoiardis in the mix of stout beer and coffee (or just stout beer)
Start placing a layer of ladyfingers, a layer of cream, another layer of ladyfingers, and another of cream, until you have your beautiful beer tiramisu. The number of layers will depends on the recipient you use. You can use a pipping bag to place the cream or two spoons.
Finally, dust generously with cocoa powder on top.
Let the beer tiramisu cool into the fridge for 4-12 hours, and enjoy!
