Preparing the brown butter takes a little more time and effort but it adds a nutty flavour to this indulgent layer cake that makes it extra-special.
Preheat the oven to 160°C. Grease a large loaf tin or 23cm square baking tin well with nonstick spray and line the bottom with baking paper.
1. Cake Heat the butter in a small saucepan over medium heat until melted, then reduce the temperature and simmer slowly until the butter is light brown. Pour the browned butter into a glass bowl or jar and set aside for at least 2 hours or until solid again.
