These are a low-fat & tasty little treat that make for a teriffic breakfast or snack. (This recipe is from the 2009 Milk Calendar). I made them using all whole wheat flour and a very dark cocoa powder, and they turned out great! Cooking Tip: Be sure to use very ripe bananas with brown spots for the best flavour and texture. Wrap cooled muffins in plastic wrap and freeze in resealable bag or airtight container for up to 1 month. For the Adventurous: Replace chocolate chips with 1/2 cup (125 mL) dried blueberries or chopped dried cherries.
