Chocolate fudge yellow cake

This was the Chocolate fudge yellow cake which we had for our Saturday dinner. But because we were so full after our dinner, my lil boy decided to skip it, and T and me shared a slice.

I had baked this cake only because there were some egg yolks left-over, and it's quite an eye-sore to see the egg yolks sitting in the fridge. It will be a waste to throw them away either. Yes, this is a pure egg yolk cake!

As my cake doomed quite a fair bit, I was eating the "scraps" after trimming the cake. Comparing, I actually like the cake better on its own, without the frosting. It tasted like good ol' butter cake! T likes the chocolate frostings, and wished I had slabbed more (and more)! Yumz
