Step 1

Preheat the oven to 400 degrees F. Line a standard muffin pan with liners and spray them lightly with oil.

Step 2

Mash the bananas in a large mixing bowl. Measure to make sure you have about 1 1/4 cups mashed banana.

Step 3

Add the non-dairy milk, oil, sugar, vinegar and vanilla to the bowl and whisk with the bananas until well combined.

Step 4

To the wet mixture, add the flour, then sprinkle the baking powder and salt on top of the flour. Stir to mix with a large spoon until just combined; be careful not to over mix. Some small lumps are fine.

Step 5

Fold in chopped walnuts or chocolate chips, if using. Using a 1/4 cup measuring cup, add batter to the liners in the pan almost all the way full. Sprinkle more walnuts/chocolate chips on top if desired.

Step 6

Bake for 20-24 minutes, until golden on top and a toothpick comes out clean. Let cool for 5 minutes in the pan, then transfer to a cooling rack. Enjoy!
