Although I first came up with this recipe because I had someone coming for supper who - genuinely - couldn't eat wheat or dairy, it is so meltingly good, I now make it all the time for those whose life and diet are not so unfairly constrained, myself included.
It is slightly heavier with the almonds - though not in a bad way - so if you want a lighter crumb, rather than a squidgy interior, and are not making the cake for the gluten-intolerant, then replace the 150g ground almonds / 1½ cups almond meal with 125g plain flour / ¾ cup plus 1 tablespoon all-purpose flour. This has the built-in bonus of making it perhaps more suitable for an everyday cake.
Made with the almonds, it has more of supper-party pudding feel about it and I love it still a bit warm, with some raspberries or some such on the side, as well as a dollop of mascarpone or ice cream.
