Preheat oven to 375°. Spray a muffin pan with non-stick oil spray.
In a large bowl, mash the ripe bananas with a fork.
Add the non-dairy milk, vanilla extract, apple cider vinegar, oil, and sugar to the mashed bananas and stir with a fork to combine. You can also whisk it.
Add the flour, baking powder and salt to the wet ingredients and stir until combined. Do not over mix.
Fold in the Craisins and Grape Nuts with a spatula.
Fill the muffin tin about ⅔ full. Bake in the preheated oven for about 21-23 minutes.
Take the muffins out of the oven and let them cool in the pan for about 5 minutes.
Remove the muffins from the pan and place on a cooling rack to cool completely.
Store any leftovers in an airtight container at room temperature for up to 3 days.
Notes
You can use any non-dairy milk you like. I like to use unsweetened soy milk or oat milk the best.
Make sure the bananas are very ripe for best texture and added sweetness.
Do not overmix the batter or the muffins won't be as fluffy.
Feel free to customize - Instead of craisins you can use other dried fruit like raisins or fresh fruit like blueberries.
