Apple-Cinnamon Crumble Cake

I have always been a fan of Apple Crumble and hence when I chanced upon a similar recipe in a book, I told myself to give a try on it.

For the crumbs, it is just unsalted butter rubbed in self-rising flour (sifted with cinnamon powder). For the base, it is a layer of butter cake which is thinner than usual). I was lucky that the results was very good (according to my husband). The sourness of the apple gave the whole cake a nice taste when the crumbs and the butter cake were mixed with sugar. Luckily I reduced the sugar a whole lot :)
