It's so hard to find baking materials and ingredients in manila like buttermilk and baking powder. Do you have any idea where I can purchase them?

You can go and visit Chocolate Lover Inc located at P.Tuazon Blvd, Cubao. It's my go to place for all my baking needs! Price is also a bit cheaper compared to malls and supermarkets. Here's their website so you can also check their other products: http://achocolatelover.com/products_baking_basics

Our go-to baking shop would also be Chocolate Lovers, although we prefer the one located near Tomas Morato since it's nearer to our place. If you have other concerns abour baking, join Bake Happy Manila. It's a Facebook group for baking fanatics like me! ☺️

Try visit All About Baking! Their newest branch is now open in BGC (Uptown Mall). You can find all sort of baking materials here. Here's their FB page you may want to follow for updates: https://www.facebook.com/allaboutbakingph/
