Ingredients You’ll Need
These ingredients are straightforward but chosen carefully to create layers of flavor and texture in the Banana Oatmeal Bars Recipe. Each one plays an essential role, whether it’s adding moisture, a hint of sweetness, or a bit of spice to make every bite memorable.
- 1 cup mashed bananas: This forms the natural sweet base and keeps the bars moist and tender.
- 1 large egg: Acts as a binding agent, helping the bars hold together perfectly.
- 1/2 cup peanut butter: Adds creaminess and a rich nutty flavor to complement the bananas.
- 1/4 cup brown sugar: Provides a subtle caramel-like sweetness that elevates the flavor.
- 1/4 cup honey: A natural sweetener that also introduces a lovely floral note.
- 1/2 cup milk: Keeps the mixture smooth and soft while balancing the dry ingredients.
- 2 teaspoons vanilla extract: Enhances the aroma and deepens the overall flavor profile.
- 2 ½ cups old fashioned oatmeal: The hearty backbone of the bars, contributing chewy texture and fiber (quick oats can be a substitute for a finer texture).
- 1 teaspoon baking powder: Lightens the bars slightly for a tender crumb.
- 1 teaspoon cinnamon: Adds warmth and a hint of spice that pairs beautifully with banana.
- 1/2 teaspoon kosher salt: Balances the sweetness and enhances every flavor.
- 1 cup mini chocolate chips: Little bites of chocolate bliss that make these bars feel like a treat.
How to Make Banana Oatmeal Bars Recipe
Step 1: Prep Your Baking Pan
Start by preheating your oven to 350 degrees Fahrenheit and lining a square baking pan with parchment paper. This simple step ensures your bars won’t stick and will come out cleanly, making serving easier.
Step 2: Combine the Wet Ingredients
In a large mixing bowl, add your mashed bananas, honey, milk, egg, and vanilla extract. Using a hand mixer, blend these ingredients thoroughly until smooth and well combined. This forms a luscious, flavorful base for the bars that’s both sweet and full of moisture.
Step 3: Process the Oatmeal
If you’re using old fashioned oats, pop them into a food processor and pulse a few times for a finer texture—quick oats can take their place if you prefer. This slight processing ensures the oats integrate better into the batter without making the bars too dense.
Step 4: Add the Dry Ingredients
Now it’s time to mix in the dry elements. Add your processed oats, brown sugar, peanut butter, baking powder, cinnamon, salt, and most of the mini chocolate chips to the wet mixture. Give everything a good stir until it’s just combined; be careful not to overmix, so the texture stays just right.
Step 5: Pour Into the Pan
Spread the oatmeal batter evenly into the prepared pan, smoothing the top with a spatula. Sprinkle the remaining chocolate chips on top—they’ll melt slightly during baking and create a delightful chocolatey finish.
Step 6: Bake Until Set
Pop the pan into your preheated oven and bake for about 30 minutes. You’ll know the bars are done when the center is set and the edges start to pull away from the pan slightly—this signals the perfect tender texture inside.
Step 7: Cool and Firm Up
Let the bars cool in the pan at room temperature until they’re no longer hot to the touch. For the best texture, transfer the pan to the refrigerator for about an hour—this helps the bars firm up nicely, making slicing easy without crumbling.
Step 8: Slice and Serve
Once chilled, slice the bars into 12 generous pieces. These bars taste especially wonderful warmed up a bit with a light spread of butter, turning them into a comforting treat that brightens your day.
How to Serve Banana Oatmeal Bars Recipe

Garnishes
Adding a garnish can elevate the bars visually and add a new layer of flavor. A light dusting of powdered sugar or a drizzle of melted peanut butter pairs beautifully. Fresh fruit like thin banana slices or a few extra chocolate chips on top can brighten their rustic charm.
Side Dishes
These bars make a perfect accompaniment to a hot cup of coffee or creamy yogurt, especially Greek yogurt with a drizzle of honey to echo the bars’ natural sweetness. A glass of milk or a smoothie also complements these bars wonderfully for a complete snack or breakfast.
Creative Ways to Present
For a fun twist, serve your Banana Oatmeal Bars Recipe layered with dollops of almond butter and sliced strawberries for a mini dessert parfait. Try cutting into bite-sized squares for a grab-and-go energy bite at parties or pack them individually wrapped for school or work snacks.
Make Ahead and Storage
Storing Leftovers
Store any leftover bars in an airtight container at room temperature for up to two days, or keep them in the fridge for up to a week. This helps maintain their moist texture and fresh flavor, ready whenever you crave a quick snack.
Freezing
These bars freeze exceptionally well. Wrap individual slices tightly in plastic wrap and place them in a freezer-safe bag. When you want a treat, thaw at room temperature for 30 minutes or reheat gently in the microwave.
Reheating
To reheat, pop a bar into the microwave for 15 to 20 seconds. Warming them enhances the gooey chocolate chips and softens the peanut butter, making each bite feel freshly baked. Add a little pat of butter or a drizzle of honey if you like a touch of extra indulgence.
FAQs
Can I use ripe bananas that are very soft?
Absolutely! The riper the bananas, the sweeter and more flavorful your Banana Oatmeal Bars Recipe will be. Very soft bananas also mash easily, contributing to a moist, tender texture.
Is it necessary to process the oats in a food processor?
Not at all. Processing the oats is a texture preference—smaller oat pieces blend more seamlessly into the bars, but if you love a chewier bite, you can use rolled oats as is or swap in quick oats for an even softer result.
Can I substitute peanut butter with another nut butter?
Yes, feel free to use almond butter, cashew butter, or sunflower seed butter if you want to change the flavor or accommodate allergies. Just choose one with a similar creamy consistency for best results.
How long will these bars stay fresh?
If stored properly in an airtight container, these bars will keep their freshness and texture for up to a week in the refrigerator. For longer storage, freezing is the way to go.
Can I make this recipe vegan?
You can adapt this recipe to be vegan by swapping the egg for a flax egg (1 tablespoon flaxseed meal + 3 tablespoons water) and choosing a plant-based milk. Use maple syrup instead of honey to keep it fully vegan-friendly.

Instructions
- Prep. Preheat the oven to 350 degrees Fahrenheit. Line a square baking pan with parchment paper to prevent sticking and ensure easy removal of the bars.
- Combine wet ingredients. In a large mixing bowl, add the mashed bananas, honey, milk, egg, and vanilla extract. Use a hand mixer to blend these ingredients together until smooth and well combined.
