Start by preheating your oven to 350 degrees. Grease and flour a bread loaf pan. Do this by spraying it with cooking spray oil, then place some flour into the pan and shake it around until the flour coats all sides of the pan; then dump excess flour and set it aside.

Take a mixing bowl or medium-sized bowl with a potato masher and mash the bananas until all smashed. Then add your melted vegan butter, vanilla extract, salt, baking soda, baking powder, cinnamon, nutmeg, vinegar, and plant milk; mix this until combined. Now add your sugars and stir until combined. Last, add your flour and stir until just everything is combined.

Pour the batter into your greased loaf pan and cook for 50-60 minutes until a toothpick comes out mostly clean in the middle. Let this cool in the pan for 10 minutes before removing it to a cooling rack. Let cool and then enjoy!
