5 min 1 servings 400 kcal

Ingredients

  • 60 g Rolled oats
  • 1½ tbsp Peanut butter
  • 150 ml Milk
  • 1 tbsp Chia seeds
  • ½ medium Banana
  • 1 tsp Honey

Instructions

1

Mix everything

In a jar or container, combine oats, peanut butter, milk, chia seeds, and honey. Stir well until the peanut butter is evenly distributed.

2

Refrigerate

Cover and refrigerate for at least 6 hours or overnight. The oats absorb the liquid and become thick and creamy.

3

Top and eat

In the morning, top with sliced banana and an extra drizzle of peanut butter. Stir if you like it mixed, or eat layered.

Why this recipe works

Peanut Butter Overnight Oats are an ideal solution for busy mornings. This recipe combines rolled oats, peanut butter, chia seeds, and banana, delivering a nutrient-rich meal that’s both filling and flavorful. The creamy texture ensures a delightful experience, while the addition of chia seeds provides fiber and omega-3 fatty acids. The natural sweetness from honey and banana elevates the taste without overwhelming the palate, making this dish not just nutritious but also enjoyable.

Meal preparation tips

Preparing these overnight oats is a breeze. Simply mix the ingredients in a jar, let them sit overnight, and you’ll have a delicious breakfast ready to go by morning. The oats will soften and absorb the delicious flavors, resulting in a thick and satisfying dish. For those who meal prep, this recipe is convenient as it can be made in advance and stored in the refrigerator.

Stir before you eat it

The peanut butter sits on top overnight and looks split in the morning. A hard stir pulls it through the oats. If the jar is stiff, add a splash of milk. Do not add more honey to fix the texture.

Rolled oats work. Instant oats turn to paste. One jar is about 400 kcal and 18 g protein before any extra toppings. A scoop of protein powder will change those numbers, so weigh it instead of guessing.

Recipe Notes & Tips

  • Stir the peanut butter in well — cold PB can clump. Warming it for 10 seconds helps.
  • Use a mason jar for easy transport and portion control.
  • Add chocolate chips and banana for a "PB&J" variation.

Variations

  • Low-carb version: Reduce or swap the carb source for extra vegetables or cauliflower rice.
  • Higher protein: Add an extra serving of protein or a side of Greek yogurt.

Common Mistakes to Avoid

  • Overcooking: Watch the timing carefully — overcooked ingredients lose texture and nutrients.
  • Under-seasoning: Healthy food should still taste great. Don't skip the seasoning step.

How to Store

Refrigerate overnight and up to 2 days. Serve cold. Stir before eating; add a splash of milk if it thickened.

What to Serve With This

  • Coffee: The jar is sweet enough. Skip the flavored creamer.
  • Berries: Add them in the morning so they stay firm.
  • An apple: Extra volume if 400 kcal is not enough to hold you to lunch.

Make the jars the night you shop

Four jars on Sunday cover weekday breakfasts. Keep banana slices out until the morning or they brown in the jar. Chia thickens the mix. If you skip it, use a little less milk or the oats stay soupy.

Frequently Asked Questions

Can I use powdered peanut butter?

Yes. Mix powdered PB with water first, then add to the oats. It cuts calories and fat significantly while keeping the peanut butter flavor.

How long do PB overnight oats last?

Up to 4 days in the fridge without the banana topping. Add banana fresh each morning to prevent browning.

Are peanut butter overnight oats good for weight gain?

At 400 calories with healthy fats and complex carbs, yes. Add extra peanut butter, whole milk, or a scoop of protein powder to increase calories further.

Can I make these oats vegan?

Absolutely! Use almond milk or your favorite plant-based milk, and select a vegan-friendly sweetener like agave syrup.

How can I adjust the sweetness of the oats?

You can increase or decrease the honey or substitute it with maple syrup based on your taste preference.
