I often had this last year, especially during the entire run of the Baker's Fair in Powerplant Mall. I can even finish the entire cake in one sitting.
As I miss eating it, I had the chance to have it again, when I went to Kublai's Rock in Magallanes. The Shell - Select in Magallanes sells Polly's Chocolate Cake for P380.
I was supposed to buy just a slice, which they sell for P30, but I find it too little, so I bought a whole cake instead.
Polly's chocolate cake never fails to amaze me. They're always consistent with the taste of their cake. It's always fudgy & chocolatey.
