I first whipped this up on a hectic weekday morning when I had nothing ready and now it has become my go to breakfast that even picky eaters ask for all the time.

Ingredients

  • One cup oldfashioned rolled oats: provides hearty texture and fiber, choose organic for the best quality
  • One cup milk of your choice: regular dairy or plantbased options work great, pick unsweetened to control sugar
  • One ripe banana mashed: naturally sweetens and adds creaminess, ripe ones will mash easier and taste sweeter
  • Two tablespoons creamy peanut butter: adds protein, healthy fats, and rich flavor, use natural peanut butter without added sugar or oil
  • One tablespoon pure maple syrup: a gentle sweetener, opt for real maple syrup instead of artificial syrups
  • One tablespoon flax meal or chia seeds: a boost of omega 3 fats and fiber, fresh ground flaxseed offers the best nutrition
  • Half a teaspoon pure vanilla extract: lifts the flavors and adds warmth, choose a quality extract for the best fragrance
  • A pinch of fine salt: balances sweetness and enhances all flavors
  • Optional toppings: sliced bananas, extra peanut butter, chopped nuts, cacao nibs, or cinnamon provide delicious texture and extra nutrition

Instructions

Mash the banana:
In a medium bowl mash the banana until smooth. This makes the oats creamy and naturally sweetens the mixture.
Combine ingredients:
Add oats, milk, peanut butter, maple syrup, flax or chia, vanilla, and salt. Stir well until everything is evenly combined and creamy. This stage ensures all flavors marry nicely.
Divide and refrigerate:
Divide the mixture among three jars. Seal each jar tightly and refrigerate for at least four hours or overnight to allow the oats to soak up the liquid and soften perfectly.
Stir and serve:
Stir before serving. Add a splash of milk to loosen the texture if desired then finish with your favorite toppings for extra flavor and crunch.

Storage Tips

Store your overnight oats in airtight jars or containers to maintain freshness and texture. Avoid adding fresh fruit before storing as it can cause sogginess. Wait until serving to add any fresh toppings. Use portioned jars to make grab and go breakfasts easy during busy mornings.

Ingredient Substitutions

Swap peanut butter for almond butter or sunflower seed butter for a nut free version. Use kefir instead of milk for a tangy probiotic twist that aids digestion. Replace maple syrup with honey or agave syrup according to your preference and dietary needs.

Serving Suggestions

Top your oats with a scattering of chopped nuts for crunch or a sprinkle of cinnamon to add warmth. Add a spoonful of Greek yogurt on top for extra creaminess and protein boost. Serve chilled or allow to come to room temperature if you prefer a softer texture.
