Not just for the holidays, this festive chocolate Yule Log is perfect when you need to make an easy, last-minute dessert that would impress. This Jaffa Log needs to be made the night before or on the morning of the day you’re going to serve it, to allow the flavours to develop and the biscuit to become rich and cake-like. It only needs four ingredients, and there’s no baking needed – it just needs to be refrigerated.
