Deliciously light, fluffy and moist sponge. Highly recommended. Mine took 35 mins so keep an eye on it!
Also tried this out without any lemon but added a teaspoon of vanilla essence instead. Made a lovely vanilla loaf with butter icing on top. Secret is not to mix all 5 ingredients together at once but to cream sugar and butter first, then add eggs and whisk in well, then fold in flour. Add milk right at end. YUMMY!
Just a note about the topping...for a crunchier topping try 175g granulated sugar mixed with the juice of 2 lemons. Pour over the cake while it is still just warm. Delish!!
