Equipment

Ingredients

This recipe (without toppings) yields 3 cups of overnight oats.

  • 2 large Bananas
  • ¼ cup Peanut Butter *See recipe note
  • 1 cup Old Fashioned Rolled Oats (uncooked)
  • 2 tablespoons Chia Seeds
  • ½ teaspoon Vanilla Extract
  • 1 teaspoon Ground Cinnamon adjust to taste
  • 1 tablespoon Maple Syrup (or Honey) adjust to taste
  • ⅛ teaspoon Salt adjust to taste
  • 1 cup Milk plant-based or dairy milk

Optional Toppings

  • Banana Slices
  • Peanut Butter
  • Dark Chocolate Chips

Instructions

  • In a medium bowl, add the BANANA, PEANUT BUTTER, ROLLED OATS, CHIA SEEDS, VANILLA EXTRACT, GROUND CINNAMON, MAPLE SYRUP, and SALT. Mash and stir until the mixture is smooth and creamy.
  • Add the MILK and stir again until well combined.
  • Store the oats in the bowl with a fitted lid or portion the mixture into jars with fitted lids for individual servings.
  • Cover and refrigerate for 8 hours, then use within 4 or 5 days.
  • Serve cold with optional toppings.

Notes

Use ripe or overripe bananas. A ripe banana works well, but an overripe banana adds even more natural sweetness and mashes easily into the oats.
Peanut butter type. I prefer natural, creamy peanut butter, but if you’re using a sweetened variety, consider skipping the maple syrup so your oats aren’t too sweet.
Use any milk you like. I love soy milk when keeping this plant-based, but dairy or non-dairy milk at any fat level works well in this recipe.
Sweetness is intentionally mild. This recipe relies on the combination of natural banana sweetness and maple syrup (or your sweetener of choice), so taste and adjust after chilling if needed.
Toppings and add-ins are flexible. Shredded coconut, fresh or frozen berries, or chocolate chips can be stirred in before chilling or added on top just before serving. Add a scoop of nonfat yogurt for a protein boost.
Expect a thicker texture after chilling. These oats set up creamy, but they also could use a quick stir before serving to distribute the ingredients, if needed. Add a splash of milk if you want them looser.
