An Irish chocolate cake-with a secret ingredient!

karyn ryan


Hello.. In time for Paddy's Day,, this Chocolate cake is a real irish original because it contains a secret ingredient "mashed Potato" - I kid you not. Potato we eat it so much so why not put it in a cake. This is one of my mums recipes which I "borrowed".. I hope you try it out it, it really is moist and delicious. It also has Baileys Irish cream in the filling. You can't get more irish than that.xx
"go n-éirí an bóthar leat" it means have a good journey through life an old irish way of saying Good Luck
