Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

milk (almond, oat, cashew, or dairy—whatever I have on hand)
Greek yogurt or a non-dairy alternative like coconut yogurt
old-fashioned rolled oats (I use gluten-free if needed)
vanilla or unflavored protein powder (whey, pea, or plant-based)
chia seeds
vanilla extract
flavor add-ins like bananas, apples, cinnamon, nut butter, coconut, berries, or maple syrup

Directions

I add the base ingredients (oats, yogurt, milk, protein powder, chia seeds, vanilla) into a mason jar or small container.
I stir well to make sure the oats are fully submerged. If things look dry, I add a splash more milk.
Next, I pick a flavor and mix in the add-ins—like mashed banana, peanut butter, diced apple, or pumpkin puree.
I seal the jar and pop it in the fridge to soak overnight (or at least 6 hours).
In the morning, I stir, add a little more milk if I want, and top with extra fruit or nut butter.

I enjoy it cold straight from the fridge, but I can warm it up in the microwave for 30–60 seconds if I’m craving something cozy.

FAQs

What type of oats should I use?

I stick to old-fashioned rolled oats for the best texture. Quick oats work too but are a little softer. I avoid steel-cut oats because they don’t soften enough overnight.

Can I use any kind of protein powder?

Yes! I’ve made this with whey, pea, and plant-based protein powders. I like vanilla the best for flavor, but unflavored works too.

Are these overnight oats healthy?

Definitely. They’re packed with protein, fiber, and healthy fats, especially when I add chia seeds, fruit, and nut butter. Plus, they keep me full for hours.

Can I heat them up?

I usually eat them chilled, but I’ve warmed them in the microwave and they’re just as good. I just give them a stir and add a splash of milk before heating.

Can I skip the yogurt?

If I want to skip yogurt altogether, I use a thicker plant-based alternative like coconut or almond yogurt. If I’m avoiding all dairy and substitutes, I increase the milk slightly and add extra chia seeds for creaminess.

Conclusion

These high-protein overnight oats are a breakfast game-changer. I love how easy they are to prep and how versatile the flavors can be. Whether I want something sweet like Banana Bread or fruity like Apple Pie, I can make it in minutes and be set for the week.
