In a medium mixing bowl, combine applesauce, butter, eggs, half-and-half and granulated sugar.
Mix and beat with an electric mixer for 30 seconds.
In a separate mixing bowl, combine flour, cocoa, baking soda, salt and baking powder.
Add dry ingredients to applesauce mixture.
Beat on low speed of electric mixer for 30 seconds, then on high speed for 2 ½ minutes.
Scrape the bowl with a rubber spatula occasionally.
Reserve one-half cup chocolate chips and set aside.
Fold in remaining chocolate chips and walnuts.
Pour batter into four well-greased and floured miniature loaf pans or one greased and floured 9x5” loaf pan.
Sprinkle about 2 tablespoons chocolate chips evenly over top of each miniature loaf pan.
Bake miniature pans approximately 45-50 minutes at 350° or loaf pan for 60-70 minutes at 350°.
A bamboo skewer or knife inserted in the center should come out clean when bread is fully baked.
Cool in pan(s) 10 minutes before removing to a wire rack to cool completely.
