Preheat oven to 350F (180C) and grease a 9 x 5-Inch loaf pan.
In a large bowl, whisk together the applesauce, brown sugar, honey, yogurt, egg and vanilla extract until smooth.
Sift the flour, cocoa powder, baking soda, baking powder, and salt together to avoid clumps. Add the dry ingredients to the wet ingredients and slowly stir them together, being careful not to overmix. Fold in the chocolate chips.
Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean.
Allow to cool for 15 minutes in the loaf pan, then transfer to a wire rack.
This Chocolate Chip Bread tastes best on the second day. Freeze leftovers for up to three months.
