Coffee and Walnut Cake

I found out my firm's canteen started selling this coffee walnut cake the day before I went on holiday, I bought a slice to try for breakfast although I am not a big fan of coffee, it surprised me because it taste like tiramisu and I really like it!

I was thinking of this cake throughout my whole holiday, the first thing I wanted to do after coming back was to make this cake! so glad it is very simple to make, didnt have to wait too long to have a slice ;-d
