Why You’ll Love This Recipe

I love how a serving of this plum overnight oats recipe has 20 grams of protein! I always try to get as much protein in as possible in the mornings so not only do I feel full for longer, but it’s also easier to hit my protein goals if I start early in the day.
By blending the plums into the milk, the plum flavor is evenly incorporated throughout. It’s also much easier to sneak in fruit in the overnight oats for breakfast than it is to snack on fruit throughout a busy day.
It’s super easy to make! Blend everything together and stir in the rolled oats and chia seeds, and then the fridge does the rest!

Ingredients You’ll Need

Ingredients needed to make plum overnight oats.

milk — you can use any water of your choice, from cow’s milk to non-dairy milk such as cashew milk or almond milk. If you don’t have milk, you can make it with water, like my overnight oats with water recipe. You can even get high protein milk where you can get 18 grams of protein per cup.
plums — I love the sweet and tart flavors of plums and they’re pretty nutritious! You can use red or black plums. Red plums are more sweet-sour whereas black plums are sweeter as is. You can peel them or not. You get a little extra texture if you don’t peel them plums. I prefer mine peeled.
yogurt — the yogurt works with the chia seeds to give the overnight oats a creamy texture. This recipe uses Greek yogurt as it is a great way to add a boost of protein to your overnight oats.
maple syrup — maple syrup is my preferred sweetener, but you can use your favorite one. Make sure you’re using real maple syrup and not pancake syrup in your overnight oats. Real maple syrup comes straight from trees, whereas pancake syrup is usually made with corn syrup.
vanilla extract – I prefer real vanilla extract.
salt — a pinch of salt helps balance out the flavors.
rolled oats — make sure you are using old-fashioned rolled oats. Instant oats and quick oats do not hold up as well after they’re soaked for a few hours, so I do not prefer the texture of the oats after soaking.
chia seeds — chia seeds come in both black and white seeds, but there is no difference in nutritional content. Chia seeds are also an excellent source of plant-based protein and are high in omega-3 fatty acids and fiber! When they absorb the milk and yogurt, it helps thicken the overnight oats.

Add milk, plums, Greek yogurt, maple syrup, salt, and vanilla extract to a high-powered blender and blend until smooth. I use a Vitamix.

Recipe Tips and Notes

Add a drizzle of almond butter or peanut butter on top to add a little extra protein to the overnight oats.
You can add additional Greek yogurt to add even more protein to the overnight oats.
Toppings such as chopped nuts, hemp seeds, pumpkin seeds, and sunflower seeds also add protein naturally to the overnight oats.
For an on-to-go meal, mason jars are great. 16-ounce wide-mouth mason jars are great if you plan on adding toppings, so you don’t spill anything. I also LOVE a good weck jar.
If you want some extra sweetness? Consider stirring some jam into the overnight oats!

Make Ahead Tips

Meal prep: store the plum overnight oats without any toppings in an airtight container for up to 5 days in the fridge.
Freezer: to freeze overnight oats, portion out the oats in small containers, then freeze! Thaw the overnight oats in the fridge for 6-8 hours/overnight before you’d like to eat them. You can store the overnight oats in the freezer for up to 2 months.

What are overnight oats?

Overnight oats are a no-cook method of preparing oatmeal! It’s made by soaking rolled oats in some liquid, such as milk, overnight so they become soft and digestible without having to cook it.

Are overnight oats healthy?

I would consider this plum overnight oats recipe to be healthy as the ingredients are rich in fiber, protein, and antioxidants. They also contain a wide range of vitamins and minerals!

Can you use steel-cut oats for overnight oats?

While you can use steel-cut oats, keep in mind that steel-cut oats will need to be soaked longer, and the texture will be dense and chewy in comparison. This plum overnight oats recipe, in particular, uses rolled oats, so I recommend following the recipe if this is your first time making overnight oats.
