I have been wanting to make a lemon cake using a whole lemon for a while. The important phytonutrients in lemons are found in the peel - the part we normally throw away (see tip below). This cake remedies this! Since the whole lemon is used this is quite a grown up taste and not massively sweet. I love this lemony, nutty hit – but if you love your cakes very sweet this might not be for you! Be sure to choose organic lemons to avoid wax and pesticide residues.
