Nothing can completely replace sugar in a recipe, (particularly in meringue or jam recipes, don't even try!). Sugar is used for taste, to give volume, and to give softness/moistness, and caramel colour, so is usually vital in baking recipes. However some recipes may substitute the puree of some fruit/vegetable in the place of some sugar, since the puree will add moistness and flavor. Think carrot cake, or chocolate beetroot cake, or apple puree in chocolate brownies. The cookbook "Red Velvet Chocolate Heartache, by Harry Eastwood" contains a lot of recipes using fruit/veg purees, however I've never tried any of them out so I cannot recommend it personally.
