What You’ll Need
- 1/2 cup rolled oats
- 1/2 cup unsweetened almond milk (or milk of choice)
- 1/2 ripe banana, mashed
- 1/2 teaspoon ground cinnamon
- 1 tablespoon chia seeds (optional, for thickening)
- 1 teaspoon maple syrup (optional, adjust to taste)
- 1/4 teaspoon vanilla extract
- Pinch of sea salt
Optional Toppings:
- Sliced banana
- Granola or chopped nuts
- Almond or peanut butter
- A sprinkle of cinnamon
- Greek yogurt (for extra protein)
Pro Tips
- Use very ripe bananas – The spottier, the better. They’re naturally sweet and mash easily into the oats.
- Chill overnight for best texture – While you can eat them after 2–4 hours, overnight chilling gives the oats a perfectly creamy consistency.
- Make it thicker or thinner – Adjust the milk amount based on your texture preference. More milk = looser oats; less = thicker oats.
- Add a protein boost – Stir in Greek yogurt, protein powder, or a spoonful of nut butter.
- Layer your toppings – Keep sliced banana or granola on top (not mixed in) for better texture and presentation.
Tools You’ll Need
- Mason jar or airtight container
- Measuring spoons and cups
- Small bowl and fork (for mashing banana)
- Spoon or spatula for mixing
Substitutions and Variations
- Gluten-free? Use certified gluten-free oats.
- Dairy-free? Stick with almond, oat, soy, or coconut milk.
- No banana? Use mashed pear or applesauce for a similar texture and sweetness.
- No maple syrup? Skip it entirely or use honey, agave, or date syrup.
- Add-ins: Mix in raisins, chopped apples, or flaxseed for a little variety.
Make-Ahead Tips
These overnight oats are designed for make-ahead convenience. They’ll stay fresh in the fridge for up to 4 days, so you can prep a few jars on Sunday night and have breakfast ready all week long.
If you’re prepping multiple servings, keep toppings like banana slices or granola separate until just before serving to keep them fresh and crunchy.
How to Make Banana Cinnamon Overnight Oats
1. Mash the Banana
In a small bowl, mash half of a ripe banana with a fork until smooth.
2. Combine the Ingredients
Add the mashed banana to a mason jar or container. Add oats, almond milk, cinnamon, chia seeds, maple syrup, vanilla, and salt. Stir until well combined.
3. Chill Overnight
Seal the jar and refrigerate for at least 4 hours, ideally overnight, until thick and creamy.
4. Add Toppings and Serve
In the morning, give the oats a quick stir. Add your favorite toppings like fresh banana slices, granola, nut butter, or a sprinkle of cinnamon.
Leftovers and Storage
Store your banana cinnamon overnight oats in the fridge for up to 4 days. They’re perfect for meal prep and just get creamier the longer they sit.
If the oats thicken too much, stir in a splash of milk before serving to loosen them up. Add fresh toppings right before eating to keep them from getting soggy.
