Preheat oven to 350F. Lightly grease a 9 x 5 inch baking loaf pan with cooking oil spray.
Add all ingredients except chocolate chips into a blender. Blend on high until everything is thoroughly mixed. Add in the chocolate chips and stir them into the batter.
Pour batter into baking pan. Scrape sides of blender with a spatula to make sure you get all the batter. Bake for about 40-50 minutes, or until toothpick inserted comes out clean and top of bread bounces back slightly when touched. Allow bread to cool before cutting and serving. Bread will sink and shrink down a little when cooling.
