Have you ever tried an Irish Coffee? If the answer is yes then imagine that Irish coffee in the form of an airy chocolatey mousse. This dessert is based on my vegan chocolate mousse. It’s irresistibly good and goes down super easy, I mean, my partner polished off 3 in one sitting as a “taste test”.

What’s more is these deliciously creamy pots come together in just 4 easy steps! Try serving this chocolate mousse with some homemade vegan ladyfingers (which can be used in place of cutlery!)


An Irish Coffee is a classic Irish cocktail which consists of whiskey and coffee sweetened with sugar and then topped with fresh cream. The idea is that the hot boozy coffee is drank through the cold fresh cream, making it a delicious combo of hot and cold. The thing with Irish Coffee is that they need to be made fresh, it’s not the kind of treat you can have hanging around in your kitchen or fridge. So that’s why I wanted to incorporate the amazing flavours of an Irish Coffee into a dessert that can be made ahead of time, meaning you can pull them out of the fridge right before entertaining and not have to worry about making any finicky cocktails!

We already know that coffee and chocolate are a match made in heaven. Mocha is one of the most delicious flavour combinations if you ask me. But then there’s adding whiskey to the mix, this is a whole new level of indulgence.

  • Full fat coconut milk or coconut cream: If using coconut milk, refrigerate the can overnight and then only use the thick part from the top of the can.
  • Instant coffee granules: The intense flavour of instant coffee is will give a deep espresso flavour to the mousse.
  • Dark chocolate: this will form the base of the chocolate mousse. The flavour will come through so make sure you choose a good quality chocolate, look for one with a cacao content of 70% or higher with no added dairy in the ingredients.
  • Whiskey: You can use your favourite whiskey, I normally use Jameson.
  • Pure maple syrup: The recipe calls for a little maple syrup to lift the sweetness of both the chocolate mousse and the coconut cream. If you prefer a more bitter chocolate mousse you can omit the maple syrup from the chocolate mousse part of the recipe.
  • Sea salt: a touch of salt helps to balance the sweetness and enhance the flavour of the dessert.
  • Aquafaba: This is the star of the show, aquafaba is the viscous liquid leftover from cooking chickpeas or other white legumes and is the ingredient that will create the air bubbles and “mousse” effect of the dessert.
  • Cream of tartar: This is optional but it helps to stabilise the whipped aquafaba.
  • Vanilla extract: A little vanilla is used to flavour the coconut cream topping.  I’d recommend Neilsen Massey pure vanilla extract and Taylor and Colledge vanilla bean extract.

First prepare the chocolate ganache base for the mousse. Add the coconut milk and coffee granules to a saucepan and bring to a simmer until all of the coffee has dissolved. Meanwhile, chop the chocolate very finely and add to a heat resistant bowl. Then pour the hot coconut milk mixture on top of the chocolate and allow it to sit for five minutes or so. Add in the whiskey, maple syrup and sea salt and give the ganache a good stir to combine all of the ingredients. It’s important that the ganache is not hot when you mix it with the aquafaba so set it aside for 10-20 minutes until it reaches room temperature.

Meanwhile, prepare the aquafaba by adding it to a large bowl with the cream of tartar. You can use an electric handheld whisk or stand mixer to beat the aquafaba for approximately 8 minutes, until it reaches stiff peaks.

Next you’ll combine the chocolate ganache and aquafaba. When incorporating the whipped aquafaba into the chocolate ganache, do so in small increments and be careful not to over-mix as you will deflate the bubbles that have formed in the aquafaba. Use a spatula to gently fold the aquafaba into the cooled ganache, one large spoonful at a time. Transfer the chocolate mousse to serving jars and refrigerate for 4 hours or until set.

While the mousse sets in the fridge you can go ahead and prepare the cream topping. This part couldn’t be easier, you simply whisk the ingredients together in a bowl until smooth, and then spoon or quenelle the cream on top of the chocolate mousse.

    Couldn’t believe when I had all these things in my press already! They came out so nice even my non vegan mother loved them. Thank you!

  2. Hi Christina, I have these setting in the fridge overnight – are they nicer to take out of fridge and serve at room temperature and to just add the topping before serving? Thanks so much for all the recipes

    1. Hi Siobhán,

      They’re best served chilled, and yes topping them before serving is perfect. If you wanted to, you could prepare the cream topping ahead of time and refrigerate it in an airtight container so it’s ready to go for serving! Hope you enjoy them x
