Peanut butter cup overnight oats that taste like you’re having dessert for breakfast! They’re delicious and perfect for meal prep.
Overnight oats will forever be my favorite summer breakfast. I love being able to throw breakfast together the night before and wake up to a delicious, filling, chilled breakfast to enjoy!
I have so many recipes for overnight oats on Eating Bird Food — everything from strawberry overnight oats (that taste like strawberry shortcake) and chocolate banana overnight oats to zucchini bread overnight oats.
That said, you can never have too many overnight oat recipes and recently I was inspired to create a new recipe using one of my favorite flavor combinations ever… peanut butter + chocolate.
- 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 chocolatey flavor. I use a plant-based chocolate protein powder that is sweetened with stevia. If your protein powder isn’t sweetened, you’ll likely want to add a little sweetener, like maple syrup.
- almond milk – I like using unsweetened vanilla almond milk, but any type of milk will work.
- vanilla extract – just a touch!
- 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.

Peanut Butter Cup Overnight Oats
- Mix ingredients: Add oats, protein powder, milk, vanilla, sea salt and ½ Tablespoon of peanut butter to a bowl or jar. Stir or shake well to combine, until all the protein powder has dissolved and peanut butter has disperse.
- Refrigerate: Seal container with a lid and place in the fridge overnight.
- Remove from refrigerator: In the morning, remove bowl or jar from the fridge and stir/shake the mixture. You’ll notice that the oats soak up a lot of the liquid, so you may want to add a little more milk before serving.
- Serve: Top oats with chocolate chips and remaining peanut butter for serving.
- Store: Overnight oats will keep for up to 5 days in the fridge in a sealed airtight container.
- Chocolate chips – I like using Lily’s dark chocolate chips, but I’ve also made this recipe with a chopped up Lily’s peanut butter cup. It 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.
- Chocolate protein powder – I use chocolate protein powder, but you could also use peanut butter protein powder.
