Ingredients

Scale
  • 1 cup (90g) rolled oats (old-fashioned oats)
  • 1 large ripe banana (about 120g mashed)
  • 1/4 cup (64g) creamy peanut butter
  • 1 cup (240ml) milk (any kind; 2% dairy recommended)
  • 1/2 cup (120g) Greek yogurt (plain or vanilla)
  • 12 tablespoons (15-30ml) honey or maple syrup
  • 1 tablespoon (12g) chia seeds (optional)
  • 1/2 teaspoon vanilla extract
  • Pinch of salt
  • Optional toppings: sliced banana, extra peanut butter drizzle, chopped peanuts, dark chocolate chips, cinnamon, or yogurt

Instructions

  1. Mash the banana: Peel the ripe banana and add it to your jar or mixing bowl. Use a fork to mash until smooth with only tiny lumps remaining (about 30 seconds). If the banana isn’t super ripe, microwave it for 15 seconds to soften first.
  2. Add the peanut butter: Spoon in 1/4 cup of creamy peanut butter. If cold or stiff, microwave for 10-15 seconds to soften. Mix with the mashed banana until well combined into a uniform, tan-colored paste.
  3. Pour in the milk and yogurt: Add 1 cup of milk and 1/2 cup of Greek yogurt. Stir with a fork or whisk until the mixture is smooth and creamy. It will look thin at this point.
  4. Add the oats and chia seeds: Measure 1 cup of rolled oats and 1 tablespoon of chia seeds directly into the jar. Stir thoroughly until every oat is coated. Scrape the bottom and sides to incorporate evenly.
  5. Sweeten and flavor: Add 1-2 tablespoons of honey or maple syrup, 1/2 teaspoon of vanilla extract, and a tiny pinch of salt. Stir one final time to distribute evenly. Taste—it should be slightly sweet but not overwhelming.
  6. Seal and refrigerate: Put the lid on tightly and refrigerate for at least 6 hours, but overnight (8-12 hours) is ideal. The oats need time to soften and absorb the liquid.
  7. Enjoy in the morning: Take the jar out of the fridge. Give it a good stir—chia seeds may have settled. If too thick, add a splash of milk. Top with sliced banana, extra peanut butter, or other toppings. Eat cold or microwave for 30-60 seconds if you prefer warm oats.

Notes

For best texture, use rolled oats (not quick or steel-cut). Mash banana thoroughly to avoid chunks. Stir halfway through soaking time if possible. Let oats sit at room temperature for 5 minutes before eating for better flavor. Adjust liquid based on milk type (almond milk may need extra splash; oat milk may need less). Double peanut butter for extra richness. Make 3-4 jars at once for grab-and-go breakfasts all week; best within 3 days.
