Ingredients
Method
- Choose your container: Use a 12–16 oz jar or a sealable container to leave room for stirring and toppings.
- Mix dry ingredients: Add rolled oats, protein powder, chia seeds, and a pinch of salt to the container. Stir to distribute the protein powder evenly.
- Add wet ingredients: Pour in milk, Greek yogurt, vanilla extract, and sweetener if using. Stir thoroughly until no dry pockets remain.
- Fold in blueberries: Gently mix in the blueberries. If using frozen, add them now; they’ll thaw overnight and lightly tint the oats.
- Adjust thickness: If it looks very thick, add a splash more milk. The chia and protein will thicken it as it rests.
- Cover and chill: Seal and refrigerate for at least 4 hours, but overnight is best for maximum creaminess.
- Serve: In the morning, stir, taste, and adjust sweetness. Top with more blueberries, a sprinkle of nuts, or a spoonful of yogurt if you like.
Why This Recipe Works
Overnight oats soften in the fridge, so the texture turns creamy without any cooking. The vanilla protein powder blends with milk and yogurt to create a thick, pudding-like consistency with a pleasant sweetness.
Blueberries add bursts of freshness and antioxidants without overpowering the flavor. It’s a make-ahead breakfast that lets you control sweetness, protein, and fiber in one simple jar. Plus, it’s portable and tastes great straight from the fridge.
What You’ll Need
- Old-fashioned rolled oats (1/2 cup) – the best texture for overnight oats
- Vanilla protein powder (1 scoop, about 25–30 g) – whey or plant-based
- Milk (1/2 to 3/4 cup) – dairy or unsweetened almond, oat, or soy milk
- Greek yogurt (1/4 cup) – for creaminess and extra protein
- Chia seeds (1 teaspoon) – helps thicken and adds fiber
- Vanilla extract (1/2 teaspoon) – boosts the vanilla flavor
- Blueberries (1/2 to 2/3 cup) – fresh or frozen
- Maple syrup or honey (1–2 teaspoons, optional) – sweeten to taste
- Pinch of salt – sharpens the flavors
- Optional toppings – extra blueberries, sliced almonds, coconut flakes, or a dollop of yogurt

Storage Instructions
Store your overnight oats tightly covered in the refrigerator for up to 3 days. If the mixture thickens too much, stir in a little milk before eating.
For meal prep, make multiple jars at once and add fresh toppings right before serving. Avoid freezing; the texture becomes grainy and the berries weep when thawed.

What Not to Do
- Don’t use quick oats only: They can turn mushy. Stick to old-fashioned rolled oats for the best texture.
- Don’t skip mixing well: If the protein powder clumps, you’ll get chalky bites.
Stir thoroughly.
- Don’t add too little liquid: Protein and chia thicken overnight. Add enough milk to keep it creamy.
- Don’t add crunchy toppings too early: Nuts and granola will soften. Add them right before serving.
- Don’t overload sweetener: Vanilla and blueberries already add sweetness.
Start small and adjust.
Recipe Variations
- Lemon Blueberry Cheesecake: Add 1–2 teaspoons lemon zest and swap half the Greek yogurt for whipped cream cheese. Sprinkle with crushed graham crackers before serving.
- Almond Crunch: Use almond milk, add 1 tablespoon sliced almonds, and a few drops of almond extract. Top with extra almonds for texture.
- Coconut Vanilla: Use coconut milk, add 1 tablespoon unsweetened shredded coconut, and top with toasted coconut flakes.
- High-Protein Boost: Add 2 tablespoons powdered peanut butter or an extra 2 tablespoons Greek yogurt.
Ensure enough milk to keep it creamy.
- Low-Sugar: Skip the sweetener and use unsweetened milk. Add a few more blueberries or a dash of cinnamon for natural sweetness.
- Warm It Up: Microwave the set oats in 20–30 second bursts with a splash of milk, stirring between intervals. Add fresh blueberries after warming.
FAQ
Can I use steel-cut oats?
Not for this exact method.
Steel-cut oats don’t soften enough overnight and stay chewy. If you prefer them, par-cook first or use quick-cooking steel-cut oats and add more liquid.
What kind of protein powder works best?
Choose a vanilla flavor you enjoy on its own. Whey blends smoothly and sets thick and creamy.
Plant-based powders work too but may need an extra splash of milk to prevent a dense texture.
Can I make this dairy-free?
Yes. Use a non-dairy milk and a dairy-free yogurt or skip yogurt and add a bit more milk plus 1–2 teaspoons nut butter for creaminess.
How do I prevent clumps of protein powder?
Mix the dry ingredients first, then add liquids gradually while stirring. You can also whisk the milk, yogurt, and protein in a separate bowl before pouring over the oats.
Are frozen blueberries okay?
Absolutely.
They’re convenient and budget-friendly. Add them frozen; they’ll thaw overnight and color the oats slightly purple, which tastes great.
What’s the best jar size?
A 12–16 oz jar or container is ideal. It gives room to stir and add toppings without spills.
How much protein is in a serving?
It varies by brand, but with 1 scoop of protein powder and Greek yogurt, expect roughly 25–35 grams of protein per serving.
Can I prep a week’s worth at once?
Make up to three days ahead for the best texture.
If you need the full week, prep the dry mix in jars and add milk, yogurt, and fruit two to three days at a time.
