Why You’ll Love This Recipe
These bars combine three flavors that work beautifully together: banana, peanut butter, and chocolate. Ripe bananas and applesauce provide moisture, peanut butter adds richness, and chocolate chips give every bite a little sweetness.
Preparation is easy, too. Everything comes together in one bowl before being spread into a square pan and baked.
They’re also family-friendly and convenient for make-ahead breakfasts. Once chilled and sliced, you can keep individual portions in the refrigerator for an easy grab-and-go snack.
Ingredients
- 1 cup (230g) mashed ripe banana, about 3 medium or 2 large bananas
- ½ cup (125g) creamy or crunchy peanut butter
- ¼ cup (50g) coconut sugar or brown sugar
- ¼ cup (60g) unsweetened applesauce
- ½ cup (120ml) almond milk or other nondairy milk
- 2½ cups (213g) old-fashioned whole oats or quick oats, not instant
- 1 teaspoon baking powder
- ½ teaspoon salt
- 1 teaspoon ground cinnamon
- 1 teaspoon pure vanilla extract
- 1 cup (180g) semi-sweet chocolate chips
- Melted peanut butter for drizzling, optional
Instructions
- Preheat the oven to 350°F (177°C). Line a 9-inch square baking pan with parchment paper, leaving enough overhang on the sides to lift out the baked bars.
- Place the ripe bananas in a large mixing bowl and mash until mostly smooth.
- Add the peanut butter, coconut or brown sugar, applesauce, and almond milk. Whisk until well combined.
- Add the oats, baking powder, salt, cinnamon, and vanilla. Stir until everything is evenly incorporated.
- Fold in the chocolate chips. The mixture should be thick but still easy to spread.
- Transfer the mixture to the prepared pan and spread it evenly, smoothing the top.
- Bake the Peanut Butter Banana Chocolate Chip Oatmeal Bars for 25–28 minutes, or until the center is set. The bars may still look slightly soft when they come out of the oven.
- Cool in the pan at room temperature for 30–60 minutes.
- Transfer the pan to the refrigerator and chill for approximately 1 hour. Chilling helps the bars firm up and makes them easier to slice cleanly.
- Use the parchment overhang to lift the bars from the pan. Slice into individual portions and drizzle with melted peanut butter, if desired.
Tips & Tricks
Use very ripe bananas with plenty of brown spots. They are softer, sweeter, and easier to incorporate into the oatmeal mixture.
Both creamy and crunchy peanut butter work well. Creamy peanut butter creates a smoother texture, while crunchy peanut butter adds small pieces of peanut throughout the bars.
Don’t use instant oatmeal. Old-fashioned or quick oats provide a better structure for these banana oatmeal bars.
Let the bars chill before slicing. They remain quite soft immediately after baking, so refrigeration is important for cleaner, sturdier portions.
For a dairy-free or vegan version, choose dairy-free chocolate chips and confirm that the sugar and other packaged ingredients suit your dietary preferences.
For an attractive finish, reserve a small handful of chocolate chips and scatter them over the surface before baking.

Notes
Almond milk can be replaced with oat, soy, cashew, or another nondairy milk.
Either coconut sugar or brown sugar works well. Brown sugar gives the bars a slightly deeper caramel-like sweetness.
For vegan oatmeal bars, use dairy-free semi-sweet chocolate chips and check the labels of your remaining packaged ingredients.
You can serve the bars cold or allow them to sit briefly at room temperature for a softer texture. A drizzle of warm peanut butter makes a delicious optional topping.

FAQ
Can I use quick oats for peanut butter banana oatmeal bars?
Yes. Both quick oats and old-fashioned rolled oats work. Quick oats generally produce a slightly softer, more uniform texture, while old-fashioned oats provide more noticeable chew.
How ripe should the bananas be?
Use very ripe bananas, ideally with brown spots on the peel. Ripe bananas are naturally sweeter and mash easily into the batter.
Why are my oatmeal bars soft after baking?
These are designed to be soft and chewy rather than crisp. Cooling and then refrigerating the bars allows them to firm up considerably, which is why chilling before slicing is recommended.
Can I make these banana chocolate chip oatmeal bars vegan?
Yes. The base recipe uses nondairy milk and contains no eggs. Choose vegan-friendly, dairy-free chocolate chips and verify that your other packaged ingredients meet your needs.
Can I reduce the chocolate chips?
Absolutely. You can reduce the amount of chocolate chips if you prefer less sweetness. The bananas and sugar will still provide sweetness and flavor.
Are these oatmeal bars good for meal prep?
Yes. Their long refrigerated storage time makes them particularly convenient for preparing ahead. Divide them into individual portions so breakfast or snacks are ready throughout the week.
Storage
Keep leftover Peanut Butter Banana Chocolate Chip Oatmeal Bars tightly covered or in an airtight container in the refrigerator for up to 10 days.
Place parchment paper between layers if stacking the bars to prevent them from sticking together.
For longer storage, freeze individual bars in a freezer-safe container for up to 3 months. Separating them with parchment paper makes it easy to remove one portion at a time.
Thaw frozen bars overnight in the refrigerator or allow an individual bar to soften at room temperature before eating.
