Don't have a great apple cake or bread for you, but as for other things to do with a riches of apples:

Add some chopped apple and walnuts to any regular or bran muffin recipe you have lying around. That would be as good as bread to butter, with much less grief.

Peel and mince a tart one, and stir into your pancake batter with a
little cinnamon or pie spice.

Peel and grate one (or just a half of a good sized one) into a small pot of oatmeal while it cooks, with a a spoonful of raisins and some cinnamon.

Make homemade applesauce, it's like pie without the calories, and keeps well for a while in the fridge. Peel, chunk or slice any kind of apples, mixed bags and leftovers are the best. Put in a covered pot with maybe 1/3 cup water, not much. Cook down, and about halfway to soft, stir in sugar to taste (doesn't take much, go easy), cinnamon is optional but good. When the slices are very soft, use a potato masher to break them down sort of half-heartedly. You want to leave plenty of little chunks, not puree the stuff.
