In a large bowl cream the butter. Add in the eggs and beat till creamy. Alternately add the jar of battered Raisin Bran mix with the 1 cup of milk. Mix thoroughly. Pour batter into a large loaf pan and bake in a 375F preheated oven for 40 minutes. Or, till a knife is inserted in the center and it comes out clean. Cool for 10 minutes before removing from pan.
