Mom baked it! But this kind of cookie is very booming these days, dozens of online shops sell this kind of cookie too :) but here I live in Jakarta. Where do you live?
I suggest better you bake ones instead of buying; for your health and for your wallet too $.$
Well, why don't try to bake some? It's gonna be the rainbow cookies a la Lina Peck; you'll be the trendsetter and you can even sell them (:
Is Red Velvet or Rainbow slice of cake not happening enough in sg? Ppl in jkt are so crazy with them, as now almost every cafe have their own style of red velvet cake, or the rainbow.
