    I prepared this recipe 3 time a week sometime following your recipe , or a little different adding Greek yogurt or any yogurt in stead of the maple syrup and mix mash banana with any other fruits. Really delicious.

  2. 5 stars
    I made this recipe twice, first exactly the same, second I mixed mashed bananas with mashed blueberries and add yogurt, continue with your recipe at the end a mixture of fresh fruit.
    Was delicious.

      1. Iโ€™m in the uk and measurements are different. Is a cup of oats the same as a cup of milk??
        Also as I live alone if I half recipe can I keep the other half in the fridge

      2. Hi Sue. For UK measurements, one cup of oats will be about 90 grams. and yes you can save overnight oats in the fridge for a few days.
