Introduction:
If you’re looking for a breakfast that’s healthy, filling, budget-friendly, and requires almost zero effort in the morning, Peanut Butter Banana Overnight Oats is a perfect choice.
This recipe has become incredibly popular on Pinterest and among busy professionals in the US—and for good reason. It combines simple pantry staples like oats, bananas, and peanut butter to create a creamy, naturally sweet breakfast that feels indulgent but is actually very nutritious.
The best part? You prepare it the night before. While you sleep, the oats soak up the milk and flavors, turning into a soft, pudding-like texture. In the morning, all you have to do is grab it from the fridge and enjoy—no cooking required.
It’s also:
- High in fiber (keeps you full longer)
- Packed with healthy fats and protein
- Perfect for meal prep (make 2–3 jars at once)
- Extremely affordable (under $2 per serving)
Whether you’re rushing to work, heading to the gym, or just want a stress-free morning, this breakfast fits perfectly into your routine.
Ingredients (1 serving)
- ½ cup old-fashioned rolled oats (not instant)
- ½ cup milk (any kind — dairy, almond, oat, all work great)
- ¼ cup plain Greek yogurt
- 1 tablespoon peanut butter
- ½ ripe banana, sliced
- 1 teaspoon honey or maple syrup
- ¼ teaspoon cinnamon
- Pinch of salt

Instructions
Step 1 — Build your base. Grab a mason jar or any container with a lid. Add the rolled oats and Greek yogurt first — these go in together because the yogurt coats the oats and helps them soften overnight without getting mushy.
Step 2 — Add your milk. Pour in the milk and stir everything together until it’s well combined. The mixture will look pretty liquid-y right now, and that’s exactly right. The oats will absorb most of it by morning.
Step 3 — Add the flavor. Drop in your peanut butter (slightly warm it in the microwave for 10 seconds if it’s thick — it mixes in way easier), honey, cinnamon, and a pinch of salt. Stir until the peanut butter is fully incorporated.
Step 4 — Add the banana. Layer the banana slices right on top. Don’t stir them in — leave them on the surface so they don’t turn brown from being buried in the mixture overnight.
Step 5 — Refrigerate. Put the lid on and stick it in the fridge for at least 6 hours, but overnight is ideal. 8 hours is the sweet spot.
Step 6 — Morning of. Take it out, give it a stir, and eat it cold straight from the jar. If you like it thicker, add a splash less milk next time. If it’s too thick, just stir in a tablespoon of milk before eating.
Meal prep tip: Make 4–5 jars on Sunday night. They stay fresh in the fridge for up to 4 days. By Thursday morning, the oats are even creamier than on day one.
