Preheat oven to 350 degrees F. Lightly grease and flour a 9x5 inch loaf pan.

Cream together canola oil, brown sugar, eggs and vanilla with an electric mixer, scraping sides with a rubber spatula as you go.

Add mashed bananas and stir until well blended (do not overbeat).

Add flour and baking powder and stir again to blend well with a spatula so the batter stays “airy”.

Pour batter into prepared loaf pan.

Bake in preheated oven for 40 to 45 minutes, until a toothpick inserted into center of the loaf comes out clean.

Let bread cool in pan for at least 15 minutes, then turn out onto a wire rack.
