5-Minute Peanut Butter Banana Oatmeal

Creamy, naturally sweet, and ready before your coffee cools, this peanut butter banana oatmeal is the breakfast that gets you out the door.

It is one bowl, a handful of pantry staples, and five minutes on the stove or in the microwave. No measuring marathon, no sink full of dishes.

Why you’ll love it

• Five minutes from pantry to bowl.
• Naturally sweet from ripe banana – little or no added sugar.
• Filling – oats, peanut butter and banana keep you full for hours.
• Endlessly swappable – any nut butter, any topping.

Ingredient notes

• Rolled oats give the creamiest texture; quick oats work but go softer.
• Ripe banana does the sweetening – the browner, the better.
• Peanut butter – natural, unsweetened keeps it balanced.
• Milk or water – milk makes it creamier, water keeps it light.

How to make it

Simmer oats with milk and mashed banana until thick and creamy, stir in peanut butter, and top however you like. Full quantities are in the recipe card below.

Tips

• Mash the banana well for even sweetness.
• Stir the peanut butter in off the heat so it stays smooth.
• Add a splash more liquid if it thickens too much.

Storage & reheating

Best fresh, but leftovers keep in the fridge for up to 3 days. Reheat with a splash of milk to loosen it back up.
