As far as I know, Mernels keep their secret why their chocolate cake was very in in Los Baños. They just have opened its branch located at SM Calamba to cater the need of Calambeños which is a good thing for them not to go to LB when craving for Mernels.
Its perfect for birthday cakes, monthsary, anniversary or even just a pasalubong. They have simple designs for the cakes and very affordable price. They have also brownies which was also very yummy! You could also try that one and I assure you, you'll never forget the magic taste of Mernels.
