If there’s one thing about Australians, it’s that we love a good old combo of some of our favourite desserts. I grew up eating my Grandma’s baked goods, but some were always my favourite above all others: Anzac biscuits, ripple cakes and her signature custard and apple pie. So I thought to myself, let’s create the ultimate dessert! Aside from being undeniably delicious, one of the most amazing parts of this recipe is that it only uses 5 ingredients! Using these Anzac biscuits to make your ripple cakes adds great texture to your cakes with oats. The hidden apple inside offers a sweet fruity kick. The longer you leave your cakes the more soft and spongy your layers become. Using vanilla custard to flavour the mascarpone adds sweetness and a hint of vanilla. Make sure to refrigerate overnight to really let those flavours soak through.
