Juice carrots and apple to get pulp. Put into a mixing bowl and set aside. In another bowl, mix eggs, apple butter, oil, milk, sugar and vanilla until smooth. Add flour, cinnamon, baking powder, salt and raisins. Mix thoroughly. Add carrot and apple pulp and mix until blended. Spoon into greased or paper-lined muffin tins, filling about 3/4 full. Bake at 400 degrees F for 20 to 25 minutes.
