Cinnamon Raisin Overnight Oats

If you love oatmeal raisin cookies you’re going to go crazy for these cinnamon raisin overnight oats. Loaded with cinnamon flavor and studded with raisins, these oats are vegan, gluten-free and packed with protein.

I’m back with another overnight oats recipe! Anyone complaining? Didn’t think so! I love making new overnight oats recipes because the flavor combinations are endless!

I always make sure I get plenty of healthy fat, protein and fiber into all of my meals — especially breakfast. This helps satisfy my taste buds and keeps me fuller, longer. Oatmeal used to be one of those breakfasts that didn’t fill me up for long – mainly because I would eat sugary instant oats a.k.a carb overload without much protein or healthy fat. 

But now things are different. When I make overnight oats I strategically add protein so they’ll keep me full until lunch. For these oats I’m using vanilla protein powder because the flavor lends itself well to the cookie flavor I’m going for.

On to the rest of the recipe! Inspired by an oatmeal raisin cookie (the best!) and this regular oatmeal raisin oatmeal, I wanted to create an overnight oats version. I personally prefer overnight oats in the summer because I want all of the cold, refreshing foods instead of warm, comforting foods (which I prefer in the fall and winter).

Ingredients Needed For Cinnamon Raisin Overnight Oats

  • 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
  • vanilla protein powder – I use a plant-based vanilla 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 to your oats
  • almond milk – I like using unsweetened vanilla almond milk, but any type of milk will work
  • chia seeds – these little seeds add a bit of fiber, protein and omega-3 fatty acids and they help absorb some of the liquid which gives the oats a thicker consistency
  • vanilla
  • cinnamon
  • raisins
  • maple syrup – pure maple syrup is the perfect natural sweetener to use because it’s liquid so it blends in nicely with the oat mixture and I personally love the flavor. Honey or another natural liquid sweetener will work here. If you want to reduce the sugar in this recipe, feel free to use a sugar alternative like stevia or monk fruit

There’s a good chance you have all of these ingredients on hand so bookmark this recipe for when you feel like you don’t have anything for breakfast meal prep. This recipe is extra easy because you can throw all of the ingredients in the container the night before so in the morning you only have to stir and enjoy! Bonus points: it takes less than five minutes to prep. Everyone has time for this healthy breakfast!

Overnight Oats Ratio

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 /2 cup of oats, I use 1/2 cup of milk + 1/4 cup of yogurt (or an additional 1/4 cup of milk). For this recipe, I’m skipping the yogurt and using extra 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.

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.

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.

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.

If you love oatmeal raisin cookies you’re going to go crazy for these cinnamon raisin overnight oats. Loaded with cinnamon flavor and studded with raisins, these oats are vegan, gluten-free and packed with protein.


Ingredients

  • 1/2 cup old-fashioned rolled oats (affiliate link)
  • 1 scoop vanilla plant-based protein powder
  • 1 cup unsweetened vanilla almond milk
  • 1 Tablespoon chia seeds (optional)
  • ½ teaspoon vanilla
  • ¼ teaspoon cinnamon
  • ¼ cup raisins
  • 12 teaspoons maple syrup (optional)

Instructions

  2. Take the container out of the fridge the next morning and stir the mixture. You’ll notice that the oats soak up a lot of the liquid so you may want to add a little more almond milk before serving. Top oats with a few extra raisins and a drizzle of maple syrup (if using) and enjoy.
  3. Overnight oats will keep for up to 5 days in the fridge in a sealed container.

  1. Hi,
    I made this last night and I must say it’s amazing!!!! I thought it would be good but still better than I imagined, so easy to make and yes like you said I had everything in the cupboard. I didn’t use the protein powder instead I put a large dollop of Greek yogurt and I used the maple syrup. This is definitely a keeper! Thank you so much for the recipe x

    • Yay!! I am so happy to hear that you enjoyed these overnight oats. 🙂 I love it when you already have everything you need at home. Thanks for coming back to leave a comment, I really appreciate it!

  2. This recipe looks delicious! But would it work without the protein powder (or is there a good alternative) as I don’t really like protein powder and its not easily accessible where I live.
    Thanks!

    • Yes! It will definitely work without the protein powder. A couple things to note if you simply leave out the protein powder — you might want to use a little less liquid because the protein powder does soak up some of the liquid. And you might also want to add the optional maple syrup because the vanilla protein powder adds a little sweetness that you might be missing without it. Another idea is to use 1/4 cup of yogurt in place of the protein powder if you still want the added protein boost. Hope this helps. Let me know if you try the recipe!
