PB&J Overnight Oats (Single Serving, 29g Protein)
These PB&J overnight oats taste like a peanut butter and jelly sandwich in jar form — single serving, 29 grams of protein, ready in 5 minutes of prep. One of the highest-protein PB&J overnight oats recipe online.
PB&J overnight oats (also called peanut butter and jam overnight oats) are cold soaked oats with peanut butter mixed into the base, topped with mashed raspberries (or jam) and a dollop of Greek yogurt — the make-ahead breakfast version of a peanut butter and jelly sandwich. This recipe has 29 grams of protein per serving (most PB&J overnight oats recipes have 11-18g) and takes 5 minutes to prep.
This recipe is one of the highest-protein PB&J overnight oats recipe I’ve found anywhere online. The trick is using both peanut butter cookie protein powder AND adding Greek yogurt as a topping.
The mashed fresh raspberries on top are actually better than store-bought jelly here because they keep the sugar count low and the flavor bright. Pure PB&J nostalgia, but engineered to keep you full until lunch.

Ingredients You’ll Need
(Exact measurements are in the recipe card below. These are notes only.)
For the oat base:
- Rolled oats or quick oats — old-fashioned rolled or quick oats both work. Skip steel-cut (too chewy) and instant (turn to mush). Certified gluten-free if you need to keep it GF.
- Chia seeds — they thicken the oats and add fiber, protein, and healthy fats. Don’t skip them or you’ll get soupy oats.
- Peanut butter — natural creamy peanut butter is my go-to. Crunchy works for extra texture. Check the label for xylitol (sweetener) if you’ve ever bought a “natural” peanut butter — most are fine but worth a glance.
- Peanut butter cookie protein powder — the protein workhorse and adds even more PB flavor. I use PEScience Peanut Butter Cookie (code BAILEY for a discount). Vanilla protein powder works too if you can’t find PB-flavored.
- Unsweetened almond milk — any milk works. Dairy milk adds more protein; oat or cashew milk add creaminess.
- Pinch of salt — this is the secret. Salt brings out the peanut butter flavor and gives that “authentic PB&J” taste. Most recipes skip it. Don’t.
For the jam layer and toppings:
- Fresh raspberries — mashed with a fork to make a fresh “jam” without the added sugar of store-bought. Strawberries work too. Frozen works in a pinch — just thaw and drain liquid first.
- Plain Greek yogurt — adds 10+ grams of protein and creamy texture. Thick coconut yogurt for dairy-free.
- Chopped peanuts — for crunch. Skip if nut-free, or use sunflower seeds.
Optional add-ins: drizzle of maple syrup or honey if your protein powder isn’t sweet enough, chocolate chips (chocolate PB&J = elite), banana slices, hemp hearts, flax seeds, sunflower seed butter (nut-free swap for peanut butter).
How to Make PB&J Overnight Oats
- Mix the oat base. In a jar or bowl, stir together rolled oats, chia seeds, peanut butter, protein powder, almond milk, and a pinch of salt. Make sure the peanut butter is fully integrated — if it’s clumpy, microwave the PB for 15 seconds first to loosen it.
- Chill. Cover and refrigerate at least 4 hours (overnight is better). The chia seeds and oats absorb the milk and thicken into pudding-like texture.
- Mash the raspberries. Just before serving, put fresh raspberries on a small plate and mash with a fork until jammy. For frozen raspberries, microwave for 20-30 seconds first to soften.
- Top and serve. Pull the oats from the fridge. Add a dollop of Greek yogurt on top, then the mashed raspberries, then a sprinkle of chopped peanuts. Add a drizzle of extra peanut butter if you want full PB intensity. Eat cold.
Tips for the Best PB&J Overnight Oats
- Don’t skip the salt. This is the move. A pinch of salt brings out the peanut butter flavor and gives you the authentic PB&J taste. Without it, the recipe tastes generic. With it, it tastes like an actual sandwich. (Hat tip to Eat With Clarity who originally clued me in.)
- Use fresh raspberries instead of store-bought jam. Store jam has 20-30g of added sugar per serving. Fresh mashed raspberries give you the same flavor with a fraction of the sugar.
- If using crunchy peanut butter, save extra peanuts for topping. The extra crunch contrast is what takes it from “good oats” to “actual PB&J sandwich experience.”
- Make 3-4 jars at once. This recipe scales perfectly for meal prep. Just multiply ingredients by the number of servings and divide between mason jars.
- Microwave the peanut butter first if it’s firm. Cold or stiff peanut butter won’t mix evenly into the oats. 15 seconds in the microwave makes a huge texture difference.
- Add toppings right before eating. The Greek yogurt and raspberries are best fresh. The base can be made up to 5 days ahead, but toppings should be added day-of.
- Try chocolate PB&J. A teaspoon of cocoa powder in the base + mini chocolate chips on top = elite Reese’s-meets-PB&J energy.
Variations and Substitutions
- Vegan: Use plant-based peanut butter protein powder, coconut yogurt instead of Greek yogurt, and dairy-free milk.
- Higher protein still: Use a full scoop of protein powder (instead of half) and dairy milk. Bumps from 29g to 40g+.
- Lower sugar: Skip the maple syrup and use fresh raspberries (already lower sugar than jam).
- Nut-free (PB&J without the PB): Swap peanut butter for sunflower seed butter (SunButter), peanut butter cookie protein powder for vanilla, and chopped peanuts for sunflower seeds.
- Strawberry PB&J: Swap raspberries for fresh strawberries. Classic PB&J flavor.
- Grape PB&J: Use a tablespoon of all-fruit grape jam for a truly nostalgic flavor (and yes, the OG PB&J flavor).
- Chocolate PB&J: Add 1 teaspoon cocoa powder to the base and a tablespoon of mini chocolate chips on top.
- Banana PB&J: Add sliced banana on top with the raspberries. Banana + peanut butter is undefeated.
- Almond butter and jelly: Swap peanut butter for almond butter, peanuts for sliced almonds. Lighter, more “fancy adult version.”
- Chia jam version: Cook ¼ cup raspberries with 1 tsp chia seeds and 1 tsp maple syrup in a small pan for 3 minutes. Cool. Use as the jam layer for a true homemade jam experience.
Storage and Make-Ahead
These PB&J overnight oats keep for 4-5 days in an airtight container in the fridge. The base (oats + peanut butter + protein powder + milk) is best on days 1-3 but stays good through day 5.
Store the toppings separately. Mashed raspberries, Greek yogurt, and peanuts should be added right before eating to keep textures distinct. Pre-topped oats get soggy by day 2.
Freezer: You can freeze the oat base (without toppings) for up to 2 months. Thaw overnight in the fridge, then add fresh toppings.
FAQs
How much protein is in PB&J overnight oats? This recipe has 29 grams of protein per serving — one of the highest of any PB&J overnight oats recipe online. The protein comes from peanut butter cookie protein powder, Greek yogurt, peanut butter, chia seeds, oats, and almond milk. Most PB&J overnight oats recipes have 11-18 grams of protein, so this version is 2-3x the standard.
Can I use jelly instead of mashed raspberries? Yes — store-bought jelly or jam works as a 1-to-1 swap. Just know it’ll add 20-30g of sugar per serving compared to fresh raspberries. Strawberry, grape, or any flavor jelly works.
Can I make PB&J overnight oats without protein powder? Yes. Replace the protein powder with an additional ¼ cup Greek yogurt and 1 extra tablespoon of peanut butter. Macros change significantly — drops from 29g protein to around 22g.
How long do PB&J overnight oats last in the fridge? 4-5 days in an airtight container. The base is best days 1-3 but stays good through day 5. Add fresh toppings (yogurt, raspberries, peanuts) right before eating to keep textures crunchy and fresh.
Can I warm up PB&J overnight oats? Yes, though most people eat them cold. To warm: remove the toppings first, then microwave the base for 30-45 seconds. Add toppings after warming. The warm peanut butter + cold raspberries combo is actually really good.
Can I use crunchy peanut butter? Yes — crunchy adds great texture. If using crunchy, you might want to skip the chopped peanut topping (or keep it for extra crunch). Both work.
