A quick note on peanut butter: natural peanut butter works beautifully here, but any variety does the job. If you’re nut-free, almond butter or sunflower seed butter are great swaps.
For the jelly, don’t overthink it. Use whatever jam or preserve you love — strawberry and grape are classic, but raspberry or mixed berry take these oats to a whole new level.
Step-by-Step Instructions
This peanut butter and jelly overnight oats recipe comes together in just three simple steps. Grab two mason jars (or any lidded containers) and let’s go.
Step 1: Fill the Jars
Add 1/2 cup of old-fashioned oats to each jar. Pour in 3/4 cup of milk, then add 1 tablespoon of peanut butter and 1 1/2 teaspoons of jelly.
Give everything a good stir until the peanut butter starts to swirl through the oats. Don’t stress about getting it perfectly mixed — a few streaks of jelly are actually beautiful.
“The trick is stirring enough to combine, but leaving some swirls of jelly so every bite has a little surprise pop of sweetness.”
If you’re adding chia seeds, flax meal, or hemp hearts, toss them in now and stir again. These add a nice nutritional boost without changing the flavor.
Step 2: Refrigerate Overnight
Seal the jars with lids and pop them in the fridge for at least 4 hours, though overnight is ideal. The oats will absorb the milk and transform into a thick, pudding-like texture.
By morning, the peanut butter will have mellowed and softened into the oats beautifully. Trust the process — the wait is absolutely worth it.
Step 3: Serve and Top
In the morning, pull your jars from the fridge. You can enjoy them cold straight from the jar, or warm them up for 30 seconds in the microwave if you prefer a cozy, warm breakfast.
Top with a handful of fresh berries — strawberries, blueberries, or raspberries all work wonderfully. A little drizzle of honey adds extra sweetness if you like it on the sweeter side.
Grab a spoon, dig to the bottom of the jar, and enjoy every single layer.
Expert Tips for the Best Peanut Butter and Jelly Overnight Oats
Use Old-Fashioned Oats, Not Quick Oats
This is the biggest tip I can give you. Old-fashioned rolled oats soak up the milk overnight and create a wonderfully chewy, creamy texture. Quick oats go mushy and lose their bite.
Steel-cut oats can work too, but they need a longer soak — plan for at least 8 hours or up to 24. The result is chewier and more textured, which some people love.
Adjust the Liquid Ratio to Your Liking
The recipe as written gives you thick, spoonable oats. If you like them thinner and more pourable, just add an extra splash of milk in the morning before serving.
Like them even thicker? Use slightly less milk or add a teaspoon of chia seeds, which plump up overnight and help thicken the mixture naturally.
Warm Peanut Butter Mixes More Easily
If your natural peanut butter is stiff or separated, give it a quick stir and let it sit at room temp for a few minutes before adding it to the jar. It’ll blend in so much more smoothly.
Meal Prep Multiple Jars at Once
This peanut butter and jelly overnight oats recipe scales perfectly. Make four to five jars on Sunday and you’ve got breakfast sorted for the whole work week. Future you will be extremely grateful.

Variations to Try
Go Chocolate PB&J
Swap 1 teaspoon of jelly for chocolate spread or add a small spoonful of cocoa powder. It sounds indulgent, but it’s honestly not that far off from a balanced breakfast.
Make It Vegan
Use oat milk, almond milk, or any plant-based milk. All other ingredients are already plant-based, so this is an effortless swap. Full vegan breakfast, zero effort.
Add a Protein Boost
Stir in a scoop of vanilla protein powder with the oats and milk. You might need a tiny splash of extra milk since protein powder absorbs liquid. It keeps you full for hours.
Swap the Jelly
Try different flavors of jam each week to keep things fresh. Peach preserves with peanut butter are an underrated combination. Blueberry jam is also incredible if you want a slightly more tart flavor.
According to Healthline’s breakdown of oat varieties, old-fashioned rolled oats offer a great balance of fiber and texture — making them ideal for overnight oat recipes like this one.
Troubleshooting Common Issues
Oats Too Thick or Dry
If your oats come out thicker than you’d like, just stir in a splash of milk before eating. Start with 2 tablespoons and add more until you hit the consistency you love.
Oats Too Watery
If the oats are thinner than expected, add a teaspoon of chia seeds next time before refrigerating. They’ll soak up the extra liquid overnight and thicken everything up naturally.
Peanut Butter Too Thick to Mix
Cold peanut butter straight from the fridge can be stubborn. Let the jar sit on the counter for 10 minutes or briefly microwave the peanut butter portion for 10 seconds to loosen it.
Storage Instructions
One of the best things about this peanut butter and jelly overnight oats recipe is how well it keeps. Here’s what you need to know:
| Storage Method | Container | Duration |
|---|---|---|
| Refrigerator | Sealed jar or airtight container | Up to 5 days |
| Freezer | Freezer-safe jar (leave headspace) | Up to 3 months |
Reheating
To reheat from the fridge, simply microwave the jar (without the lid) for 30–60 seconds. Stir halfway through and add a splash of milk if needed to loosen the oats.
From frozen, thaw overnight in the fridge and then warm up in the microwave as above. The texture holds up surprisingly well after freezing.
No-Waste Kitchen Ideas
Got oats that have gotten a little too thick after a few days? Thin them out with milk and blend them into a smoothie with banana and frozen berries. Waste nothing.
Leftover jelly about to expire? This is the perfect recipe to use it up. Older jam that’s lost a little freshness is totally fine once it’s stirred into overnight oats.
What to Serve With These Overnight Oats
These jelly overnight oats are a complete breakfast on their own, but if you’re hosting a brunch or want to build a bigger spread, they pair beautifully with other morning favorites.
For a special weekend brunch, consider serving alongside a classic eggs Benedict with rich, buttery homemade hollandaise sauce. A bright mimosa recipe on the side makes it feel like a proper celebration.

Peanut Butter and Jelly Overnight Oats FAQs
Can I use quick oats instead of old-fashioned oats?
You can, but the texture will be softer and more mushy. Quick oats break down faster, so the oats won’t have much chew after soaking overnight. Old-fashioned rolled oats give you a much better bite and creamier result overall.
How long do peanut butter and jelly overnight oats last in the fridge?
They keep well for up to 5 days in a sealed container. Make a batch at the start of the week and breakfast is handled Monday through Friday. The flavor actually deepens a bit by day two or three.
Can I make this peanut butter and jelly overnight oats recipe gluten-free?
Yes, absolutely. Just use certified gluten-free oats, which are widely available at most grocery stores. All the other ingredients in this recipe are naturally gluten-free, so it’s an easy swap.
What kind of milk works best?
Any milk works — dairy, oat, almond, soy, or coconut milk all soak into the oats nicely. Oat milk gives a slightly creamier, richer result. Coconut milk adds a subtle tropical flavor that pairs surprisingly well with fruity jam.
Can I add protein powder to this recipe?
Yes, and it works great. Stir in one scoop of vanilla or unflavored protein powder along with the oats and milk. You may need to add a small extra splash of milk since protein powder absorbs liquid. It keeps you full well into the afternoon.
