RM put me onto this recipe a while ago. I had hoped to make it with some fresh limes from Reiver's tree while I was in NZ, but I never quite got to it. Luckily we had a bunch of limes in the freezer here though and Granny Smith apples are easy to come by, so I decided to give it a try after I got home instead.

I cut back the sugar significantly in the cake. And I was tempted to skip the icing altogether. But TF was keen on having a bit of frosting, so I did end up using it in the end.

The icing was good. Although I was definitely glad to have cut back the sugar in the cake once the frosting was added. That said, I think that next time I'd be inclined to swap out the American buttercream for a cream cheese icing. I think the cream cheese tang would complement the other flavours nicely. And cream cheese icings tend to need proportionally less sugar and butter to begin with. So, while still not a health food by any stretch, it would still make for a marginally less sweet and calorific topping.
