Ingredients

For the oats:

• 1 cup rolled oats (not instant; old fashioned oats hold their texture overnight)
• 2 tbsp chia seeds (they thicken the mix into a pudding)
• 2 tbsp peanut butter, plus more for drizzling (natural or regular both work)
• 1 cup milk of choice (dairy, almond, or oat milk)
• 1/2 cup Greek yogurt (adds creaminess and protein)
• 1 tbsp honey or maple syrup (adjust to taste)
• 1/2 tsp vanilla extract
• 1 pinch salt (sharpens the peanut flavor)

For topping:

• 1 banana, sliced
• 1 tbsp peanut butter, warmed for drizzling
• 2 tbsp chopped peanuts

How to Make Peanut Butter Overnight Oats

1. Combine. Add oats, chia seeds, peanut butter, milk, yogurt, honey, vanilla, and salt to a large bowl.
2. Stir well. Mix until the peanut butter is fully incorporated and no dry oats remain. The mixture will look thin. It thickens overnight.
3. Portion. Divide the peanut butter overnight oats mixture between 2 jars or airtight containers. Seal with lids.
4. Chill. Refrigerate at least 8 hours, or overnight. The oats soften and the chia swells into a thick pudding.
5. Top and serve. Stir each jar. Add sliced banana, a drizzle of warm peanut butter, and chopped peanuts. Eat cold, straight from the jar.

Tips for the Best Peanut Butter Overnight Oats

• Use rolled oats. Instant oats turn mushy. Steel cut oats stay too hard.
• Stir the peanut butter in well. Natural peanut butter separates, so mix thoroughly to avoid oily pockets.
• Chia is not optional for texture. It gives peanut butter overnight oats their thick pudding body. Without it the mix stays thin.
• Sweeten to taste. Start with 1 tbsp honey. Add more after chilling if you like it sweeter.
• Loosen if needed. If the oats are too thick in the morning, stir in a splash of milk.
• Warm the drizzle. Ten seconds in the microwave makes peanut butter pourable.
• Double the batch. This recipe scales easily. Use a big bowl and 4 jars.

Easy Variations

• Chocolate peanut butter overnight oats. Add 1 tbsp cocoa powder to the mix.
• Berry version. Swap banana for fresh blueberries or strawberries on top.
• Crunchy style. Use crunchy peanut butter instead of creamy.
• Higher protein. Add a scoop of vanilla protein powder and an extra splash of milk.
• Apple pie oats. Replace banana with diced apple and a pinch of cinnamon.
• Nut free. Use sunflower seed butter instead of peanut butter.

Storage and Make Ahead

Peanut butter overnight oats keep 4 days refrigerated in sealed jars. Make a full batch on Sunday for easy weekday breakfasts.

Since this recipe uses dairy, get the jars into the fridge within 2 hours of mixing, per USDA food safety guidelines. Do not leave them on the counter overnight.

Add fresh toppings just before serving. Banana browns if added the night before. The base itself improves with a full overnight rest.

Serving Ideas

Eat these peanut butter overnight oats straight from the jar for the fastest breakfast. A jar also packs well for work or school.

For a weekend brunch spread, serve jars alongside our blueberry muffins. The muffins bake while the oats chill, so everything lands on the table together.

Peanut butter overnight oats keep 4 days in sealed jars in the fridge. The texture is best in the first 2 days.

You can, but they are designed to be eaten cold. Warm them gently in the microwave if you prefer, then add toppings.
