You’re going to love these delicious and creamy peanut butter overnight oats. They’re easy to prep and pack in a good amount of protein from the Greek yogurt and peanut butter.
I’ve made (and shared) so many different overnight oat variations, but I’ve been loving this flavor lately. It’s based off my easy overnight oats recipe, but we’re adding peanut butter directly into the overnight oat mixture instead of just using it as a topping. This ensures every bite has a little peanut butter flavor.
If you’re a peanut butter lover like me, you’ll know that I pretty much like to drizzle all of my overnight oats with peanut butter (or another nut butter) and I already have several pb inspired overnight oats combos — everything from peanut butter cup overnight oats to peanut butter and jelly overnight oats. All that said, sometimes it’s nice to get back to basics and that’s what this recipe does!
The base “recipe” for overnight oats is so simple! The hardest part is getting the right ratio of oats to liquid, but if you follow my recipes you’ll be set!
I aim for a 1:1 ratio of rolled oats to milk, plus half as much yogurt. So for 1 cup of oats, I use 1 cup of milk + 1/2 cup of yogurt (or an additional 1/2 cup of milk). This seems to give the oats the perfect consistency, not too thick, but not soupy. For the liquid, I usually go for non-dairy milk like almond milk, but you can use whatever milk you have on hand and if you really want to experiment you can try using different liquids like fruit juice.
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.
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.
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.
