I've been searching the recipe of this cake for a very longgggg time. Hmmmm...and there's none. Nobody know this secret recipe from Secret Recipe Cake in Malaysia. Because my mother and 2 of my sister (Najmin & Munirah) really x10 like it, so i try to come out with a recipe that pretty much taste like the cake..i think..:D... I search for the best white cake recipe & white choc mousse recipe in the internet...waalaaa..and then i put some macadamia nuts in the filling like above pic. Yesss, i made it and its yummyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyyy...but please a big slice per day only..:D. All the frosting is from white choc mousse.
