Preheat your oven to 350°F (175°C). This ensures that your banana bread bakes evenly.
Grease your loaf pan with a little canola oil or line it with parchment paper for easy removal.
In a large mixing bowl, mash the very ripe bananas with a fork until smooth. You want them completely mashed to incorporate fully into the batter.
Add the granulated sugar, dark brown sugar, canola oil, eggs, and vanilla extract to the mashed bananas. Whisk until the mixture is well combined and smooth.
In a separate bowl, whisk together the all-purpose flour, baking soda, ground cinnamon, and fine-grain sea salt until thoroughly mixed.
Gradually add the dry ingredients to the wet ingredients, folding gently with a rubber spatula until just combined. Be careful not to overmix; a few lumps are okay!
Pour the batter into the prepared loaf pan and smooth the top with your spatula.
Bake in the preheated oven for 50-60 minutes or until a toothpick inserted into the center comes out clean. If the top is browning too quickly, cover it loosely with aluminum foil.
Once baked, remove the banana bread from the oven and let it cool in the pan for about 10 minutes. Then, transfer it to a wire rack to cool completely before slicing. Enjoy your Easy Dairy-Free Banana Bread warm or at room temperature!
