How do you make vegan banana-baked oatmeal without eggs and sugar?

  1. Mash bananas and mix wet ingredients

    First, mash the bananas with a fork (you’ll need about 2 full cups). In the meantime, preheat the oven to 356°F / 180°C. Lightly grease an 8-inch square baking pan with neutral oil. I used sunflower oil. Set it aside.
    Next, in the bowl with the mashed bananas add the milk, peanut butter, maple syrup, and vanilla extract. Mix it all together until well combined.

Can you bake mashed bananas?

Certainly! Mashed bananas act as a binding ingredient in many baking recipes (I use them instead of eggs), provide a tender and moist texture for baked goods, and give a unique aroma to them. They really are so amazing, that’s why we love them so much!

I would say beyond good! Oatmeal, banana, peanut butter, and walnuts are a fantastic combo that even picky-eaters approve of.

Notes

  • Since the sweetness of this recipe depends on the sweetness of bananas we use, it’s best to use ripe/overripe bananas. Keep in mind that this banana bake isn’t overly sweet, if you prefer it sweeter add a tablespoon or two more maple syrup.
  • You can totally omit the walnuts for a nut-free vegan baked oatmeal.
  • You can use any dairy-free milk of choice although I don’t recommend coconut milk because it’ll affect the flavor.
