Beat the butter in a bowl with an electric mixer until smooth and lump free. Add the cream cheese and beat until well incorporated. Slowly add the icing sugar in three batches, mixing well after each addition. Add the vanilla and beat on high speed for a few minutes until the icing is light in colour and fluffy.
Refrigerate in an airtight container for up to 1 week.
I tried this delightful cake at Kim Evan’s Little & Friday Cafe in Newmarket, Auckland. Not long after my friend, Izaak and I brought the book and began experimenting with Kim’s treats. These lemon cakes would have to be my absolute favourite and very popular amongst friends, family and colleagues. This recipe makes 12 mini cakes or 1 double layer cake. I have made these recipe many times in a range of sizes including mini cakes, a large cake and doubling this recipe to make a six layer cake (pictured below).
