Step 1
Start by heating your oven to 350°F (175°C). Prepare your muffin tin by either greasing and flouring the cups or lining them with paper liners. In a big bowl, whisk together the whole wheat flour, brown sugar, cocoa powder, and a pinch of salt. In another bowl, mix the water, mashed banana, canola oil, and apple cider vinegar until well combined. Pour the wet ingredients into the dry ones and stir until you have a smooth batter. Fold in the chocolate chips, then spoon the batter evenly into your muffin cups.
