Ingredients You’ll Need
Grab a jar, a bowl, or any container that will convince you you’re organized.
- Rolled oats – 1/2 cup (old-fashioned, not instant).
- Milk – 1/2 cup (dairy, almond, oat, your choice).
- Greek yogurt – 1/4 cup (or non-dairy yogurt). Adds creaminess. Don’t be shy.
- Chia seeds – 1 tbsp (for texture and tiny nutritional flex).
- Banana – 1 small, mashed (ripe = sweeter).
- Blueberries – 1/3 to 1/2 cup (fresh or frozen).
- Maple syrup or honey – 1 tbsp (adjust to taste).
- Vanilla extract – 1/4 tsp (sophistication in a drop).
- Pinch of salt – brings flavors to life.
- Optional toppings: chopped nuts, granola, extra banana slices, extra blueberries, a dash of cinnamon.

Step-by-Step Instructions
- Mash the banana.
Use a fork and get it nice and smooshy. A few chunks are fine — texture is good. - Mix the base.
In your jar or bowl, combine oats, chia seeds, and a pinch of salt. Stir. - Add the creamy stuff.
Pour in milk, then add yogurt, mashed banana, maple syrup, and vanilla. Stir until everything looks cozy and evenly damp. - Fold in blueberries.
Gently stir half the blueberries into the mixture. Save the rest for topping so your oats look like you tried. - Seal and chill.
Cover the jar and refrigerate overnight (or at least 4–6 hours). The chia and oats will plump up and become spoon-ready. - Top and enjoy.
In the morning, give it a stir, add remaining blueberries and any toppings you like. Eat straight from the jar, at your table, or while still half-asleep — no judgment.

Common Mistakes to Avoid
- Using instant oats: They turn into mushy sadness. Use rolled oats for the best texture.
- Skipping chia seeds: They help thicken and keep things satisfying—don’t skip unless you hate consistency.
- Over-sweetening: Ripe banana + a little maple = plenty. Taste before you drown it in syrup.
- Forgetting to chill long enough: Give it at least 4 hours. Less time = dry oat regret.
- Adding crunchy toppings too early: Granola goes on right before eating; otherwise it loses its crunch.
Alternatives & Substitutions
- Dairy-free: Use almond, oat, or soy milk and coconut yogurt. Still creamy, still delicious.
- No yogurt? Add an extra tablespoon of chia and a splash more milk for creaminess.
- No banana? Use applesauce or mashed cooked pear for sweetness.
- Blueberry swap: Raspberries, strawberries, or a mixed berry medley work beautifully.
- Protein boost: Stir in a scoop of your favorite protein powder (vanilla is a safe bet).
My two cents: blueberries and banana are a dream team, but don’t be afraid to experiment—this recipe is forgiving.
FAQ (Frequently Asked Questions)
1. Can I use instant oats instead of rolled oats?
You can, but the texture will be softer and more porridge-like. Rolled oats give the best overnight texture.
2. How long do overnight oats last?
Stored in the fridge, they keep well for up to 3 days. After that, the texture changes and magic fades.
3. Can I make a big batch?
Totally. Multiply ingredients and store in a big container or individual jars for grab-and-go breakfasts.
4. Are overnight oats healthy?
Yes—packed with fiber, whole grains, and fruit. Watch added sweeteners if you’re tracking sugar.
5. Can I add nuts or seeds?
Please do. Almonds, walnuts, sunflower seeds, or extra chia make it more satisfying.
6. Can I eat them cold?
Absolutely. Cold is the point. If you prefer warm oats, gently microwave for 30–60 seconds.
7. Will frozen blueberries make it soggy?
If you stir frozen berries in the night before, they’ll release juice and tint your oats purple (cool). If you want intact berries, add them in the morning.
