Preheat oven to 350. Line baking sheets with parchment, if using.
In a small bowl, combine the flour, cocoa, baking powder, baking soda and salt. In a large bowl, combine the margarine, fruit juice, applesauce and vanilla and mix until it looks fairly combined.
In batches, add the dry ingredients to the wet until well incorporated. Add the chocolate chips.
Scoop cookies by the tablespoon, approximately 2 inches apart, onto the prepared baking sheet.
Bake for 9–10 minutes, until the cookies have spread and edges are set.
Remove from oven and let cool on sheets, on a cooling rack, for 10 minutes before removing from sheet to finish cooling on rack.
Store leftover cookies loosely covered at room temperature.
