Mix dry ingredients in a large bowl.
In a large measuring cup, mix oil and bananas.
Stir banana mixture into flour mixture, and add apple juice (may need a bit more than 2 Tbsp) until mixture is moist.
Put into 8″ cake pan and bake at 350 °F for 25-30 minutes until golden brown.
May instead be baked as muffins at 350 °F for 18-20 minutes. Will make 18 muffins.
Be sure to use unbuffered vitamin C crystals and not buffered. Most vitamin C crystals are corn-derived. The vitamin C crystals are to activate the baking soda, so another equivalent acid could be substituted. This could be vinegar, lemon juice, cream of tartar, etc.
