It’s my Dad’s birthday and this is his birthday cake! I’ve been planning it for a while and I’m so pleased with how delicious it turned out. It’s an intense chocolate-y and stout-y cake with an amazing “Baileys” buttercream frosting.
The frosting was inspired by my vegan Irish Cream Ice Cream which uses Irish whiskey, a little bit of cocoa powder and a little bit of coffee to recreate the flavour of Baileys. You wouldn’t know the difference! And the cake itself is slightly adapted from a recipe I found over at Fat Girl Trapped in a Skinny Body.
Apparently Guinness isn’t (generally) vegan but there is a vegan option; Foreign Extra Guinness. It’s a lot stronger and more bitter but I think it works better in this cake as the flavour comes through a lot more. I was able to find it in my local supermarket but you can also purchase it online or use another vegan-friendly stout.
Vegan Guinness Chocolate Cake with "Baileys" Buttercream Frosting
For the Chocolate Guinness cake (adapted from Fat Girl Trapped in a Skinny Body)
- 250 g / 2 cups plain flour
- 120 g / 1 cup unsweetened cocoa powder
- 2 tsp baking soda
- 220 g / 1 cup caster sugar
- 100 g / 1/2 cup light brown sugar
- 1/2 tsp salt
- 480 ml / 2 cups Foreign Extra Guinness this is apparently the only vegan Guinness
- 120 ml / 1/2 cup vegetable oil I used mild olive oil
- 1 tsp vanilla extract
For the "Baileys" buttercream frosting
- 250 g / 1 cup vegan butter I used 'Pure' sunflower butter
- 1 tsp vanilla extract
- 600 g / 5 cups icing sugar
- 2-3 tbsp Irish Whiskey I used Jamesons
- 1/2 tsp cocoa powder
- 1/2 tsp very strongly brewed coffee
Preheat oven to 170c / 350f. Grease and line two 8 inch sandwich tins.
In a bowl sift the flour, baking soda, cocoa powder, salt and sugars. Make a well in the centre, pour in the beer, oil and vanilla. Whisk until there are no lumps.
Pour into the prepared tins and bake for 25-30 minutes, until a cake tester comes out clean.
Once baked, let them cool for 15-20 minutes in their tins before transferring them onto a cooling rack.
To make the buttercream, cream the vegan butter and vanilla extract together in a stand mixer. Add the icing sugar in a large tbsp at a time until well mixed.
Beat in the whiskey, cocoa powder and brewed coffee. Taste and adjust quantities if needed until it tastes just like Baileys!
Once the cake has completely cooled, spread the frosting on top of one layer, sandwich the two layers together and then top the cake with the rest of the frosting.
Serve and enjoy! It will keep in the fridge for up to 3 days, covered.
