Ingredients Needed for Peanut Butter Cup Overnight Oats
- old fashioned rolled oats – rolled oats are the best for overnight oats. Instant/quick oats and steel cut oats don’t work the same because they don’t absorb liquid like rolled oats do.
- chocolate protein powder – this is what gives the overnight oats their rich, chocolatey flavor and most of the protein.
- milk – I like using unsweetened vanilla almond milk, but any type of milk will work.
- vanilla extract – just a touch for a hint of vanilla sweetness.
- sea salt – a pinch of sea salt is the perfect flavor enhancer and brings out the nutty flavor of the oats.
- chocolate chips – I like using Lily’s dark chocolate chips because they’re sugar-free and low in carbs. I’ve also made this recipe with a chopped up Lily’s peanut butter cup instead of the chocolate chips. If definitely takes the pb cup overnight oats to a whole new level!
- peanut butter – I highly recommend using peanut butter for this recipe since it is peanut butter cup inspired, but if you want to swap it for a different nut butter, go right ahead.
How Long Do Overnight Oats Need to Soak?
Given the name, you’d assume overnight oats need to soak overnight, but you can actually make them in 2-4 hours if you’re in a rush. While it does take some time for the oats to absorb the liquid, they don’t necessarily have to be soaked overnight.
I recommend at least 8 hours for true overnight oats, but there have been mornings where I decide I want overnight oats for breakfast even though I didn’t prep them the night before. When this happens I’ll make them the morning of and let the oats soak for just 2-4 hours. With this quick soak, they’re not as soft as overnight oats that have soaked longer and they’re a bit more liquidy, but they’re still delicious.
Can You Eat Overnight Oats Hot?
Short answer, yes! You can definitely warm up overnight oats, but the whole point of overnight oats is to eat them cold like muesli. Even if you think cold oats sound strange, I recommend giving it shot before you write them off. Of course, if you simply can’t do the cold oats you can always heat them up. Just pop the overnights oats in your microwave, cooking in 30 second increments until the oats are warm throughout and enjoy.
How Long Do Overnight Oats Last?
When stored in an airtight container in the fridge overnight oats should last for up to 5 days. They will soften more the longer they sit so I find they’re best on days 1-3, but they’re still safe to eat on days 4 and 5. With this said, overnight oats are great for meal prep. Feel free to make a whole batch for the week on Sunday. I like prepping them in wide mouth 16 oz mason jars.

Soooo good! It seems like a classic flavor, which means you can never go wrong with it. Simple, yet filling and delicious. Be mindful if calorie intake is important for you, since it can be a bit high due to the peanut butter.

I’m so glad to hear you enjoyed this recipe, Venkat! Thanks for the review :).
The perfect thing to have for the best meal of the day! So satisfying! I did not have chocolate protein powder, so I used half a scoop of plain protein powder and about 2 tsp of some chocolate spread stuff (I’ve also done this using cocoa powder). I did top with cocoa nibs instead of chocolate chips, and I would highly recommend because it adds such a satisfying crunch!
Ah yay! I’m so glad this recipe was a hit, Madeline! Thanks so much for the review. I really appreciate it!
