Before getting started, pre-heat your oven to 350° F and prepare your loaf pan by spraying it with non-stick cooking spray.
Using a fork, mash up the bananas, and cream (or mix) them with the sugar.
Add the egg to the sugar mixture, mixing well.
Mix the dry ingredients and the canola oil into the sugar mixture.
Gently fold 1 cup of the chocolate chips into the bread batter, mixing them in well.
Pour or scrape the batter into the prepared loaf pan, and sprinkle the top with the extra 1/4 cup of chocolate chips.
Bake at 350° F for about 1 hour, or until the top is a deep golden-brown and a toothpick or cake tester inserted into the center comes out clean.
Let it cool in the pan for a good 10 to 15 minutes; then run a knife around the edge, and plop it out onto a wire rack to cool completely.
Slice and serve.
