These banana oat breakfast bars turn ripe bananas and everyday pantry ingredients into an easy breakfast you can bake once and enjoy throughout the week.
Old-fashioned rolled oats give the bars plenty of texture, while mashed banana, applesauce, and a little maple syrup provide moisture and gentle sweetness. They’re soft rather than crunchy, easy to portion, and convenient when sitting down to breakfast isn’t happening on schedule.
They also give those increasingly spotted bananas on the counter somewhere productive to go. 😂
Why You’ll Love These Breakfast Bars
- Easy to make: Mix everything in one bowl and bake.

Ingredients
- 2 cups old-fashioned rolled oats
- 3 very ripe medium bananas, mashed
- ½ cup unsweetened applesauce
- ½ cup unsweetened plant milk
- ¼ cup pure maple syrup
- 2 tablespoons ground flaxseed
- 1 teaspoon vanilla extract
- 1 teaspoon ground cinnamon
- 1 teaspoon baking powder
- ¼ teaspoon salt
Instructions
- Preheat the oven to 350°F (175°C). Lightly grease an 8-inch square baking pan or line it with parchment paper.
- Add the mashed bananas, applesauce, plant milk, maple syrup, ground flaxseed, and vanilla to a large mixing bowl. Stir until well combined.
- Add the rolled oats, cinnamon, baking powder, and salt. Stir until everything is evenly incorporated.
- Let the mixture rest for about 5 minutes so the oats can begin absorbing some of the liquid.
- Spread the mixture evenly in the prepared baking pan and gently smooth the top.
- Bake for 28–35 minutes, or until the center is set and the edges are lightly golden.
- Let the bars cool in the pan for at least 15 minutes before lifting them out and slicing.
- Cut into 8 bars and serve warm or allow them to cool completely for meal prep.
Yum’s Tips for Banana Oat Breakfast Bars
Use very ripe bananas. The darker and more spotted they are, the more banana flavor and natural sweetness they’ll bring.
Use old-fashioned rolled oats. Quick oats absorb liquid differently and can change the finished texture.
Give them time to cool. The bars continue to firm as they cool. Cutting them immediately from the oven can leave you with banana oatmeal rubble. Still edible, but we’re making bars. 😂
Don’t overbake them. These should remain soft and moist inside rather than becoming dry and hard.
Banana Oat Breakfast Bar Variations
Add walnuts or pecans: Fold in ½ cup chopped nuts for crunch.
Add berries: Fold in about ½ cup blueberries. Fresh or frozen can work; if using frozen, add them without thawing first.
Add more spice: Try a pinch of nutmeg or ginger with the cinnamon.
Add some crunch: Sprinkle a small amount of chopped nuts or rolled oats over the top before baking.
Make them less sweet: Reduce the maple syrup if your bananas are especially ripe and sweet.
Storage & Meal Prep
Let the bars cool completely before storing them.
Keep banana oat breakfast bars in an airtight container in the refrigerator for up to 5 days. Individual bars can be reheated briefly or enjoyed chilled or at room temperature.
For longer storage, wrap individual bars and place them in a freezer-safe container. Freeze for up to 2 months and thaw overnight in the refrigerator.
For an easy morning routine, portion the cooled bars individually after baking. Then breakfast is already decided before the refrigerator door even opens.
Nutrition Highlights
Rolled oats provide whole grains and fiber, while bananas contribute carbohydrates and potassium. Ground flaxseed adds fiber and plant-based fats, and using applesauce helps keep the bars moist.
These bars can also be paired with fruit, nuts, nut or seed butter, or another protein-rich food to build a more substantial breakfast.
Perfect Pairings
Serve a bar with fresh berries, sliced apple, or orange segments for an easy breakfast.
A spoonful of peanut, almond, or sunflower seed butter adds richness and makes a simple pairing.
Coffee or tea works naturally alongside the cinnamon and banana flavors, while a smoothie can turn one bar into part of a more substantial morning meal.
Yum’s Note
I like breakfasts that don’t require me to start from zero every morning. These bars are exactly that kind of recipe: mix a few familiar ingredients, bake one pan, and breakfast is already waiting for the next several days.
And ripe bananas have once again been rescued from that very short distance between “I’ll use those tomorrow” and “How did they get that dark?” 😂
