  • 2 large ripe bananas
  • 3/4 cup rolled oats
  • 1 cup water or your vegan milk of choice I used regular soy milk.
  • 1/2 teaspoon cinnamon
  • 4 tablespoons peanut butter
  • 0-3 teaspoons maple syrup to taste


  • In a large bowl, mash together all of the ingredients except the maple syrup until the bananas are as smooth as possible.
  • Taste and add maple syrup, 1 teaspoon at a time, until you get the desired sweetness
  • Divide the mixture between two mason jars, and stick them in the fridge. Go to sleep. Wake up, and eat your oats!


You can make these overnight oats up to a day ahead, but you definitely want them to soak for at least 6-8 hours before you eat them. If they don’t soak long enough, the texture is…less than pleasing.
