Hi Ironchef, that looks like biko (a different kind of rice cake) to me because of the consistently dark topping (brown sugar & coconut) and the texture of the filling which looks like dense sticky rice.
a close-up picture of a cassava cake slice. Cassava cakes normally have yellowish toppings with brown spots (which is scorched coconut milk & condensed milk).
What with so many different kinds of rice cakes, it could be that the term 'Bibingka' is being used as a convenient generic term by Filipino immigrants and their descendants to refer to any rice cake. Within the Philippines however, people normally call each dessert by its correct name. So there's pichi-pichi, maja-blanca, sapin-sapin, biko, puto-bumbong, palitaw, kutsinta, puto, cassava cake and bibingka (the thick pancake kind). The generic term for all these desserts is 'Kakanin' and not Bibingka.
Dina, there are many Cassava cake recipes on Google. I hope you find what you are looking for.
