The perfect fall overnight oats
Imagine the perfect fall morning. Waking up to the smell of a fresh apple crumble baking in the oven. Watching the leaves fall from inside a cozy house with a book. These are all the feelings you're going to be feeling when you take a bite of these apple crumble overnight oats.
The only difference? You'll probably be running out the door when you're eating these.
Sadly, I don't have as many of those slow mornings as I wish could happen. Which is why easy meal prepped overnight oats like these have become a staple in my life! So here's a run down of what you can expect from these apple crumble overnight oats:
- A cozy cinnamon base. By combining our oats with milk, yogurt, chia seeds and lots of cinnamon we create the perfect base to get us into the fall mood.
- The perfect apple crumble topping. The best part about an apple crumble is obviously the cinnamon sugar covered apples and crisp topping. Which is why I knew I had to recreate that for these apple crumble overnight oats!
- A balanced breakfast. These apple cinnamon overnight oats not only taste amazing they are also Dietitian approved! These protein overnight oats contain multiple sources of protein including- milk, Greek yogurt, chia seeds and protein powder! Combined with the fibre from the oats- these are sure to keep you full all morning long.

How to make overnight oats with protein powder
As a Dietitian whenever I'm making a new breakfast recipe I always want it to have two things.
- Fibre
- Protein
Or as I like to remember it 'protein for power and fibre for fullness.' These two nutrients will always make up the base of most of my meals and snacks but especially my breakfasts!
If you've been around here awhile you might know how much I love oats. Oats will forever be my number one fibre source for breakfast. They are one of the few breakfasts that will actually keep me full longer than a few hours so they are a staple in my life. The problem is, they don't contain ton of protein on their own. As someone who is always wanting to boost protein wherever I can to help replenish my muscles, protein powder has become my new favourite addition to overnight oats. All you have do do is add one scoop (about 2 tablespoons) of your favourite protein powder to your next batch of overnight oats
You might be wondering... doesn't the protein powder make your overnight oats gritty?
The answer is NOPE! As long as you are using the right protein powder I find that not only can you not even tell there's added protein, but the overnight oats with protein powder actually taste better than they do without it.
My personal favourite protein powder is Nuzest vegan protein. I've been using it for years in all my recipes including smoothies, baked oats, baked goods, and protein overnights oats and have found it's one of the only ones that doesn't have a weird aftertaste or gritty texture.

Ingredients needed for apple crumble overnight oats:
Oats- Duh! You can't have apple cinnamon overnight oats without oats. This is arguably the most important ingredient in the recipe....quick, minute or rolled oats all work. The only thing I recommend is that if you are gluten free please make sure the oats you use are certified gluten free!
Apple- The ingredient that turns these cinnamon overnight oats into apple cinnamon overnight oats! Any apples will work however I like to go for sweeter, less sour apple varieties when I'm using them in recipes. My personal favourites are royal gala, pink lady, honeycrisp or jonagold!
Cinnamon- This recipe uses LOTS of cinnamon to get that create the perfect fall overnight oats.
Protein powder- I talked a bit above about how much I love overnight oats with protein powder. I personally love using Nuzest smooth vanilla vegan protein. However if you don't want to use protein feel free to leave it out and add an equal amount of oats!
Brown sugar- We use a tiny bit of brown sugar while sauteeing the apples for these apple crumble overnight oats. If you don't want to use it feel free to leave it out and simply sautee your apples in just the cinnamon! Another option if using coconut sugar!
Chia seeds- I always use chia seeds in my overnight oats to help soak up some of the excess moisture and create the perfect, thick overnight oat consistency.
Milk- Any milk will work!
Greek yogurt- An extra bit of creaminess and protein to make these TRUE protein overnight oats! I use plain Greek yogurt (either 0 or 2% typically). Any yogurt will work if you don't have Greek yogurt. I would personally recommend sticking with a thicker yogurt if you have the option to but if not- no worries!
Toppings- Chopped walnuts or pecans are totally optional but I love them to really bring these oats together!
How to make these apple cinnamon oats
Apple cinnamon overnight oats are incredibly simple to make. PLUS the recipes makes enough for 5 portions meaning all you need is 10 minutes and you have breakfast for the entire week!
Step 1: Prepare your oat base by mixing together oats, chia seeds, coconut (if using), vanilla extract, maple syrup, milk, and cinnamon. Mix until fully combined and then evenly divide your oat mixture amongst five jars (since this is a meal prep recipe it makes 5 servings! Feel free to halve the recipe if you aren't needing 5).
Step 2: Prepare your yogurt topping by mixing yogurt, maple syrup and cinnamon in a medium bowl. Once fully combined, divide about ¼ cup of the mixture into each of the five jars. The yogurt should just sit ontop of the oats (or feel free to mix it all together).
Step 3: Arguably the best part- making your cinnamon coated apples! In a small pan over medium-high heat add some coconut oil. Allow the coconut oil to melt, once hot add your diced apple, brown sugar and cinnamon and mix. Allow the apples to cook for about 3 minutes, stirring occasionally. You'll know they're done when you can smell them and their beginning to soften and brown! Divide the apples between the five jars (it should be about ¼ cup in each jar)!
Step 4: Top with chopped walnuts and seal up your jars and place them in the fridge for at least 2 hours but preferably overnight. This allows the chia seeds to expand and the oats to soften, giving it the creamiest pudding-like texture.
