This one is easy, for a mini size & quite good. The only thing is that at times you really do have to cut it out of the disposable pan!

It does not call for decorations - although I don't know why you couldn't do something fancy on top.
Sonys Mommys Fruitcake
1½ lb chopped dates
1½ lb pecan halves
½ lb candied cherries
½ lb candied pineapple
½ lb coconut or
½ lb almonds, sliced
2 cans Eagle Brand milk
Mix all ingredients well. Use disposable 8½x4x2½ pans. Grease & flour pans. Bake at 225 for 2 hours. Do not overbake. Cool in pans on rack. Turn pans upside-down on rack for several minutes, then thump bottom of pans to remove. Cut if necessary to remove. Consume immediately, or wrap in cloth soaked in apple cider or cherry brandy, then foil.
I also have this recipe, which I prefer. It calls for mini muffin pans instead of loaf pans. I know that's not why you're looking for, but maybe he could come up with some kind of idea to arrange a bunch of the mini muffins into a decoration? The fruitcake is actually much better than the other one; we like that one a lot - it's just that this one is outstanding...soft, moist, mmmm!

It is more complicated though.

3 eggs
1¼ c flour
1/8 tsp baking soda
