Ingredients

Scale
  • 1/2 cup (45g) rolled oats
  • 1/2 cup (120ml) milk (whole, 2%, or dairy-free)
  • 1/4 cup (60g) plain Greek yogurt
  • 2 tablespoons (32g) creamy peanut butter
  • 1 medium ripe banana, sliced
  • 1 tablespoon (15ml) honey or maple syrup
  • 1 tablespoon (12g) chia seeds (optional)
  • 1/2 teaspoon vanilla extract
  • Pinch of salt

Instructions

  1. In a small bowl, whisk together the milk, Greek yogurt, honey or maple syrup, and vanilla extract until smooth.
  2. If peanut butter is thick, microwave for about 10 seconds to soften.
  3. In a clean mason jar, add 1/4 cup of the rolled oats to the bottom.
  4. Sprinkle chia seeds (if using) over the oats.
  5. Pour about half the milk-yogurt mixture over the oats. Tap the jar gently to settle.
  6. Arrange about half the sliced banana in a single layer over the oats.
  7. Spoon about 1 tablespoon of peanut butter over the banana.
  8. Add the remaining 1/4 cup oats, then pour the rest of the liquid mixture over the top. Tap again.
  9. Layer the remaining banana slices and finish with the remaining tablespoon of peanut butter on top.
  10. Optionally, gently swirl the top layer of peanut butter into the top oats with a knife or skewer.
  11. Screw the lid on tightly and refrigerate for at least 4 hours, preferably overnight.

Notes

Use room-temperature ingredients for better absorption. Don’t overmix to keep layers distinct. Slice bananas right before layering to prevent browning. For thinner oats, add an extra tablespoon of milk. Jars keep in the fridge for up to 5 days. Not recommended for freezing.
