This banana bread overnight oats recipe transforms your morning routine into a delightful experience with minimal effort. The combination of creamy oats and sweet banana creates a nostalgic banana bread flavor in a nutritious breakfast jar that's ready when you wake up.
I started making these overnight oats during especially busy weeks when I needed breakfast ready to grab and go. Now my family requests them regularly, especially when fresh bananas are ripening too quickly on our counter.
Ingredients
- Banana: the star ingredient providing natural sweetness and that classic banana bread flavor
- Rolled oats: choose thick cut old fashioned oats for the best texture rather than quick oats
- Milk: creates the perfect creamy consistency as it soaks into the oats overnight
- Walnuts: add healthy fats and a satisfying crunch that mimics traditional banana bread
- Maple syrup: provides a touch of natural sweetness that complements the banana perfectly
- Vanilla extract: enhances the dessert like flavor profile without adding sugar
- Cinnamon: adds warmth and that classic banana bread spice flavor
- Nutmeg: a pinch brings depth and complexity to the overnight oats
- Kosher salt: balances the sweetness and enhances all other flavors
Step-by-Step Instructions
- Mash the Banana:
- Take a medium banana and thoroughly mash it with a fork until mostly smooth with some small chunks remaining for texture. Place the mashed banana at the bottom of your mason jar or container to create a flavorful base layer.
- Combine All Ingredients:
- Add rolled oats, milk, chopped walnuts, maple syrup, vanilla extract, cinnamon, nutmeg, and salt to the jar containing the mashed banana. Stir everything thoroughly until well combined, making sure there are no dry pockets of oats.
- Refrigerate Overnight:
- Secure the lid on your jar or container and place in the refrigerator for at least 6 to 8 hours, or overnight. This resting time allows the oats to soften and absorb the flavors of the spices and banana, creating that magical banana bread flavor profile.
- Serve and Enjoy:
- When ready to eat, give the oats a good stir. Top with fresh banana slices and an extra drizzle of maple syrup if desired. Enjoy cold straight from the fridge or warm it up in the microwave for 30 to 60 seconds if you prefer a warm breakfast.

The maple syrup in this recipe is my secret ingredient that truly elevates these oats from good to exceptional. I discovered its importance when I ran out one morning and used honey instead. While still delicious, the maple syrup adds that distinctive warm sweetness that perfectly complements the banana and really captures the essence of banana bread in oatmeal form.
Meal Prep Magic
These overnight oats are perfect for batch preparation. Simply multiply the recipe and prepare several jars at once for a week of ready to go breakfasts. The mixture stays fresh in the refrigerator for up to 4 days, making this an excellent Sunday prep option for busy weekday mornings. The flavors actually continue to develop and improve after the first day.
Dietary Adaptations
This versatile recipe easily accommodates various dietary needs without sacrificing flavor. For dairy free versions, substitute almond milk, oat milk, or coconut milk for traditional dairy milk. Each alternative adds its own subtle flavor profile to complement the banana. For a gluten free option, ensure you use certified gluten free oats. To make it vegan, simply use plant based milk and check that your maple syrup is purely sourced.
Customization Ideas
The beauty of overnight oats lies in their adaptability to personal preference. Try adding a tablespoon of chia seeds for extra omega 3 fatty acids and a pudding like texture. For a protein boost, stir in a spoonful of your favorite nut butter before refrigerating. Chocolate lovers can add a teaspoon of cocoa powder or a few chocolate chips. For added freshness, mix in berries just before serving to contrast with the banana flavor.
