Peanut Butter Overnight Oats with Jam | These healthy overnight oats are amazing! They're so quick and easy to make and really do remind me of the classic PB&J sandwich. One of the best healthy overnight oats for weight loss recipes out there.

It's finally September! Which means we can forget about beach days, flamingo floaties and ridiculous temperatures of 100F+ and start thinking about crunchy fall leaves, pumpkin spice lattes and fun back-to-school recipes like this one. At least us grown-ups can. I'm pretty sure kids don't get nearly as excited about back-to-school recipes as we do. But we've done the school thing, so we've earned it, right?

These peanut butter overnight oats with jam are my latest breakfast obsession. Although they might sound a little naughty (spoonfuls of fat-loaded peanut butter and sugar-laden jam can't be good for you, right?!) I switched out the bad stuff for healthy alternatives.

PB2 replaces the ordinary peanut butter and contains just 23 calories per tablespoon instead of 94! And for a healthy twist on the jam, I suggest you use my recipe for strawberry chia seed jam. It's much easier to make than traditional strawberry jam, requires just 3 ingredients and is loaded with fibre, thanks to the chia seeds. If you need this to be a low FODMAP breakfast recipe, swap out the honey in the jam for an equal amount of maple syrup or ordinary sugar.

What would you say if I told you I've never, ever had a PB&J sandwich? It's true! Up until I was 18 and moved in with my boyfriend, I'd never even had peanut butter at all! We never had it at home when I was growing up and I guess I just thought it was some weird thing only Americans ate. Turns out it's something delicious that everyone eats. And I missed out on its peanut buttery goodness for a full 18 years!

Why haven't I ever had a PB&J sandwich? The flavours just don't appeal to me. Mix them together so you've got peanut butter overnight oats with jam and I'll devour it and lick the bowl clean. But stick the flavours between 2 slices of bread and I'll be looking in the fridge to see what else there is to eat. Weird, right?

Now peanut butter and Nutella sandwiches - I've had plenty of those! And I combine peanut butter and chocolate together in recipes all the time. Hello chocolate peanut butter cup overnight oats! But I think this overnight oats recipe is the first time I've ever actually mixed peanut butter and jam together and couldn't get enough of it. Maybe it will be the start of a beautiful friendship!

      Thanks so much, Debra! I do love recipes like this that require a teeny tiny bit of prep with a big pay off. Hope you love the jam, too! 🙂

  4. Calleigh Keibler - TheForkBite

    Many years ago, these overnight oats became a "thing" in the blogosphere and to be honest; I was excited to try them out. It's been a while I tried them since, and if circumstances permit, I prefer using steel-cut oats.

    • Nicola

      Can you believe I've never made overnight oats with steel cut oats?! I made steel cut oats ONCE in the slow cooker I don't know what I did wrong but the smell and the texture were terrible. I tried a different recipe and pretty much the same thing happened. I'm sure it was me doing something wrong, but it put me off for life!

  5. Sarah Newman, Vegan Chickpea

    This is definitely my kind of breakfast! No matter how old I am I will never grow out of loving PB&J 😀

    • Nicola

      Glad to hear it, Sarah! Some things are just too good to grow out of! 🙂
