Just in time for Saint Patrick’s Day
Although this Irish Cream Mousse Cake is great all throughout the year
If you need a stunning cake to impress just about everyone
Simple four ingredient Irish Cream Mousse Cake is the way to go!
I’ve baked my best recipe for fudge brownies as the base for this cake
But you can use just about anything you like the best!
To avoid turning on the ovens altogether and keep this dessert 100% no bake
You can make up a quick chocolate sandwich cookie crust instead, just like you would for a cheesecake!
Irish cream buttercream icing is completely optional
However since this is a no sugar added recipe for the Irish Cream Mousse
The buttercream really added a perfect compliment to that rich deep triple chocolate
That’s right ~ Triple Chocolate!
Fudge brownie base, chocolate mousse and Irish Cream ganache too!
Let’s talk about Irish Cream
Even though Bailey’s now makes a vegan Irish Cream, I’ve made a homemade recipe anyway
It’s so incredibly easy and I saved a ton of money by doing it this way!
Jameson is my whiskey of choice for baking (and in my younger days ~ for drinking too! Shhh!)
So buying a bottle of whiskey versus buying a bottle of Irish Cream was a no brainer
I can use the whiskey in so many more baking recipes rather than being chained to just Irish Cream that I would probably only use once a year
Substitutions & Notes for Success:
For those who cannot use alcohol in their baking I would suggest to use coffee as a substitute
Those who do not use coffee either
I would suggest to click through to my Ferrero Rocher Mousse Cake recipe instead of this one
I am using cashews as the base for this mousse recipe
So if you must stay away from nuts I would recommend to use this recipe for chocolate mousse instead
In addition to the vegan chocolate couverture and cashews it is simply Irish Cream and whipped cream folded in!
Silk brand makes my life so much easier now with their vegan heavy whipping cream in a carton *not sponsored
Silk®
However if you are not fortunate to get your hands on that product I have several other homemade options for you here!
To make a no bake crust for this mousse cake simply combine 1½ cups of your favorite cookie
Crushed up with 4 Tablespoons of melted vegan butter
Press it into the bottom of a spring form pan and refrigerate while you prepare the mousse recipe
I have this Irish Cream Mousse Cake listed as serving 16 people because this is one rich cake!
One small slice is all you need!

An especially wonderful thing about your recipes Gretchen is how many options you give people to take part in making one of your delicious plant based desserts. You rock.
You never cease to amaze me! This looks and sounds DELICIOUS!
Hi Gretchen, would it be possible to substitute the cashews for a different kind of nut like almond or something else? Thank you, the recipe looks amazing.
I was able to find unsalted cashews and made this and it was absolutely amazing
