Lemon Drizzle Cake is a always a favourite, but if you bake two rounds, drizzle, then sandwich with a deep layer of cool creamy mascarpone mixed with tangy, buttery lemon curd, you are on to a real winner. I made this for a cake sale at work today, and I think I could have made another couple of cakes and it would still have sold. Really, REALLY good, just make it, eat it and ignore the calories! I found this recipe on Waitrose's site. This recommends using home-made lemon curd, which would be perfection, but I didn't have the time. Instead, I used Wilkinson's of Tiptree's bought stuff - it is very good, made with whole egg, butter and Sicilian lemons. Not cheap. But worth it. Also, forgive the picture. I was too knackered to take photos last night, and it disappeared this morning before I thought to ask someone to take a snap, so this pic from Waitrose will have to do.
