Preheat oven to 350 degrees F.
Stir together flour, baking soda, baking powder and spices.
In a separate bowl, cream together the butter and sugar until light and fluffy.
Beat in the egg and then slowly add a portion of the dry ingredients, then a little of the applesauce and continue alternating wet and dry ingredients, beginning and ending with dry ingredients.
Add the raisins, walnuts and vanilla at the end.
Turn into a greased and floured pan, and bake 35 to 40 minutes or until cake tests done. To test for doneness, insert a toothpick into the center of the cake - it should remain clean when removed.
Cool the cake in the pan.
Dust with confectioner's sugar after removing from the pan, when cake is cool.
