I know it's only August, but I'm already dreaming of fall recipes! I live on a subtropical island, which means fall here is pretty much identical to summer. Never-ending sunshine, temperatures constantly around 105F and non-stop sweating. But that doesn't stop me gazing at all the gorgeous fall-inspired photos on Pinterest. Piles of crunchy leaves just begging you to jump in, hands in thick winter gloves wrapped around a steaming latte and couples snuggling up to each other as they go pumpkin picking. You know the ones I'm talking about.

But since I don't get to experience any of that stuff myself unless I get off and travel way north of the equator (which isn't going to happen any time soon - sigh!) I'm stuck with experiencing fall through food. Which, too be honest, is one of the best parts of the season! These brown sugar cinnamon cookie overnight oats is the perfect healthy breakfast to help you transition from summer into fall. They're chilled overnight oats perfect for summer, because nobody can handle bowls of steaming hot oatmeal right now! But with the cinnamon and brown sugar, they've got all the snuggly, cuddly flavours of fall.

Would it be too corny to say these cinnamon cookie overnight oats are like a hug in a jar? Well that's just tough because that's definitely the descriptive phrase I'm going with. Because it's so true! I'm telling you, make yourself a jar and you'll totally agree with me. All you've got to do is round-up the 6 simple ingredients, mix them altogether and then let the fridge to the rest of the work until you're ready to eat. That's what I love about overnight oats. They're crazy simple. And super yummy!

These cinnamon cookie overnight oats were inspired by my healthy cinnamon roll overnight oats. It's one of my all-time favourite overnight oats recipes of all time and I know you love it to because it's one of my most popular recipes year-round. These oats are really similar to the cinnamon roll ones, but they're a bit healthier and less fuss, since you don't have to bother with making a cream cheese swirl. And when the sky is blue and the sun is shining, we could all do with a little less fuss in the kitchen, don't you think?

    It's almost autumn weather already where I live in Sweden, so I'll be envying your tropical temperatures soon enough! These overnight oats look great. I love the cinnamon flavour, and am always collecting low FODMAP recipes to share with my nutrition clients. Thanks!
