So rather than giving in to my first (probably-heading-for-diabetes) impluse and just throwing all those ingredients into my blender and making sweet fluffy lemon butter icing and eating it out of the bowl with a teaspoon while watching some equally soft fluffy movie, I looked up 'lemon cake' and came across a cooking blog and a really great story that sounds like it came directly from that aforementioned fluffy movie.
Thereby coming close to ticking both my boxes.
And here is 'her' cake, just out of my oven. It smells divine. It's one of those ones you pour lemon and sugar over the top the instant it comes out of the oven, so it has that lovely crisp, tart topping.
