I've always loved applesauce cake. James Beard gives a wonderful recipe in American Cookery and there is also a nice one in The Joy of Cooking. This is my version. I've added blueberries because I love the flavors of blueberries and apples together. If berries are not in season, use 1 cup of golden raisins as a substitute. I also use both whole wheat and white flour because it makes me feel that I'm making something healthy. whether any cake made with butter and brown sugar can be healthy is questionable, but regardless, people seem to like the way this tastes. —sweet enough
sift all the dry ingredients together and set aside
using an electric hand mixer or a mix master or whatever you usually use to make cake batter, cream together the butter and brown sugar until light and fluffy. add the eggs one at a time and then add the vanilla extract and the lemon zest.
at a low speed, blend in about half of the flour mixture. alternate blending in the applesauce and the rest of the flour until just blended.
using a spoon or spatula mix in the blueberries, apples and the walnuts.
spoon batter into pan and bake for 50 minutes or until cake springs back when touched.
