Wash the prunes, soak, and cook them as directed previously. Drain, stone, and cut in pieces or chop them.
Break an egg in the mixing bowl. Beat it and add the chopped prunes. Put the water drained from the prunes in a measuring cup and fill up the latter with milk. Add this liquid to the egg and prune mixture. Then proceed as in making Plain Muffins. Turn into an oiled bread pan. Bake in a moderate oven (325 degrees F.) 45 to 60 minutes.
Raisins or dates may be used instead of prunes. These fruits may be cooked before adding to the other ingredients or they may be used uncooked. If the latter plan is followed, use 1 1/4 cupfuls milk instead of 1 cupful liquid.
