A quick, no-cook breakfast made with rolled oats, peanut butter, banana, and Greek yogurt, soaked overnight for a creamy, pudding-like texture. Perfect for meal prep and naturally sweetened with ripe banana.

Ingredients

Scale
  • 1 cup (90g) rolled oats
  • 1 cup (240ml) milk (whole, 2%, or oat milk)
  • 1/4 cup (60g) plain Greek yogurt
  • 3 tablespoons (48g) creamy peanut butter
  • 1 medium ripe banana, mashed (about 1/2 cup or 120g)
  • 1 tablespoon (15ml) maple syrup or honey (optional)
  • 1/2 teaspoon vanilla extract
  • Pinch of fine sea salt
  • Optional toppings: sliced banana, chopped peanuts, dark chocolate chips, chia seeds, cinnamon, extra peanut butter

Instructions

  1. In a medium mixing bowl, mash the ripe banana with a fork until mostly smooth with a few small lumps.
  2. Add the milk, Greek yogurt, peanut butter, maple syrup (if using), and vanilla extract. Whisk or stir until fully combined and no peanut butter streaks remain.
  3. Pour in the rolled oats and pinch of salt. Stir until every oat is coated. The mixture will be thin and soupy.
  4. Divide the mixture evenly into jars or airtight containers, leaving about 1/2 inch of headspace. If adding dry toppings like chocolate chips or chia seeds, sprinkle them in now and stir gently.
  5. Seal the jars tightly and refrigerate for at least 6 hours, preferably overnight (8-12 hours).
  6. In the morning, stir the oats. If too thick, add a splash of milk. Top with desired toppings and serve cold or at room temperature.

Notes

Use room temperature ingredients for easier mixing. Do not skip the salt—it balances sweetness and enhances peanut butter flavor. For creamier oats, let the mixture sit in the fridge for 15 minutes before dividing into jars. Add fresh fruit toppings just before serving to prevent browning. Oats keep in the fridge for up to 5 days; texture becomes denser over time. To reheat, warm gently in a saucepan over low heat with a splash of milk.
