Grease two 9" x 5" loaf pans with baking spray. Set aside. Preheat oven to 350 degree F.
In a large mixing bowl, combine butter and bananas. Blend until bananas are mashed and mixed with butter. Add in sugars and beat until combined.
Add in flour, baking powder, baking soda, salt, vanilla, cinnamon, nutmeg and milk. Beat until well combined. Add in eggs and beat well. Fold in carrots and apples.
Pour into greased pans. Bake for 60 minutes, until toothpick in center comes out clean.
Remove from oven and cool on rack for 10 minutes. Remove from pans and cool completely.
For frosting: beat cream cheese with sugar, milk and vanilla until smooth (about 3-4 minutes). Spread over cooled bread. Slice and enjoy!
Notes
No need to mash the bananas first! Use an electric mixer to mash the banana as you combine it with the butter.
Want a less sweet apple carrot banana bread? Skip the cream cheese frosting. It's delicious both ways.
This bread is perfect for freezing! If you won't be eating both loaves right away, wrap one in foil and a freezer bag and store in the freezer.
Apple Banana Carrot Bread keeps well in the refrigerator for about 1 week. Frozen bread stays good for about 3 months.
