Combine flour, cocoa, baking soda, baking powder and salt. In a different bowl, beat the margarine (softened) with the sugars. Mix in the eggs and bananas. Stir in the dry ingredients. Fold in the chocolate chips. Pour into 3 greased mini loaf pans (or one large loaf pan). Bake at 350° for 40-45 minutes (or 60-70 for the large size). Cool in pans for 10 minutes, then remove. Drizzle with chocolate glaze if desired.
