PB & J Overnight Oats are one of those breakfasts that feel a little nostalgic and a lot satisfying.
You get the creamy peanut butter, sweet jam, and hearty oats all in one bowl.
The best part? You mix everything in just a few minutes at night, put it in the fridge, and breakfast is ready when you wake up.
It’s creamy, a little nutty, slightly sweet, and super filling. I make this all the time when I want something easy but still comforting.

Why I Love This Recipe
The first time I made this was during a busy week when I needed something fast in the morning. I had oats, peanut butter, and a jar of jam in the fridge. It reminded me of a PB&J sandwich, so I tried mixing it into overnight oats.
The next morning it tasted like dessert for breakfast.
Now it’s one of my go-to meal prep breakfasts because it’s:
- Ridiculously easy – mix, chill, eat
- Creamy and satisfying
- Packed with protein and fiber
- Great for meal prep
- Tastes like a classic PB&J
And the texture after soaking overnight is perfect—soft oats, thick peanut butter, and sweet ribbons of jam.
What You’ll Need
- 1 cup rolled oats
- 1 ½ cups milk
- 2 tablespoons peanut butter
- 2 tablespoons strawberry jam
- 1 tablespoon chia seeds
- 1 tablespoon honey
- ½ teaspoon vanilla extract
- Pinch of salt
Tools
- Medium mixing bowl
- Spoon
- Measuring cups
- Measuring spoons
- 2 jars or containers with lids
Pro Tips
- Stir well before chilling. Peanut butter can clump. Mixing well helps it blend into the oats.
- Use old-fashioned rolled oats. Quick oats get too soft overnight.
- Add jam last for swirls. This gives you those classic PB&J ribbons instead of everything blending together.
- Adjust sweetness. Taste the mixture before chilling and add more honey if you like it sweeter.
Substitutions and Variations
- Almond butter instead of peanut butter
- Raspberry or grape jam instead of strawberry
- Oat milk or almond milk instead of dairy milk
- Greek yogurt (¼ cup) for extra creaminess and protein
- Mashed banana for natural sweetness
Make Ahead Tips
These overnight oats stay fresh in the fridge for up to 4 days, so they’re perfect for meal prep. Make a few jars at once and breakfast is ready all week.
PB & J Overnight Oats Recipe
Step 1: Mix the Base
In a medium mixing bowl, add 1 cup rolled oats, 1½ cups milk, 1 tablespoon chia seeds, 1 tablespoon honey, ½ teaspoon vanilla extract, and a pinch of salt. Stir until everything is evenly combined and the oats are fully coated in the milk.
Step 2: Add the Peanut Butter
Add 2 tablespoons creamy peanut butter to the oat mixture. Stir until the peanut butter melts into the oats and the mixture becomes creamy and slightly tan in color.
Step 3: Portion and Add Jam
Divide the oat mixture evenly between two jars. Spoon 1 tablespoon strawberry jam into each jar and gently swirl it into the oats so you see streaks of jam.
Step 4: Chill Overnight
Place lids on the jars and refrigerate for 6–8 hours or overnight. The oats will absorb the milk and thicken into a creamy texture.
Step 5: Stir and Serve
In the morning, stir the oats. If they’re too thick, add 1–2 tablespoons milk and mix. Top with an extra drizzle of peanut butter or jam if you like.

Why This Recipe Works (Quick Science)
Overnight oats work because oats absorb liquid slowly.
- Rolled oats absorb milk overnight, softening without cooking.
- Chia seeds act like a thickener, absorbing liquid and creating a creamy texture.
- Peanut butter adds fat, which makes the oats taste richer and more satisfying.
By morning, everything blends into a thick, spoonable texture.
Common Mistakes
Using quick oats
They turn mushy overnight.
Not mixing well
Peanut butter can clump if it isn’t stirred fully.
Too little liquid
Oats need enough milk to soften properly.
Skipping salt
A small pinch balances the sweetness.
What to Serve With
PB & J overnight oats are filling on their own, but they pair nicely with:

- A smoothie
- Hot coffee or tea
Leftovers and Storage
- Store in sealed jars in the fridge
- Keeps fresh for up to 4 days
- Stir and add a splash of milk before eating if thick
