Skinnymixers Guinness Cake

skinnymixer’s Guinness Stout Cake

Sharing is caring!

This Guinness Stout Cake is a decadent delight, with its luscious chocolatey richness and velvety cream cheese frosting.

You’ll never guess what makes this chocolate cake so moist… the Guinness! 

It’s a true indulgence that’s perfect for any celebration.

My friend Mez has been baking this heavenly treat for my birthday for a number of years now and has finally agreed to share the recipe with the Skinnymixers Community

This recipe is inspired by and adapted to Thermomix from Nigella Lawson’s Chocolate Guinness Cake that is featured in her cookbook Feast. You can find the original recipe and conventional cooking instructions here. 

Mez has been a massive Nigella fan for a number of years. I’m confident that Mez’s love of cooking came directly from the pure joy Nigella has for food.
