Ingredients for Peanut Butter Oatmeal Banana Bread Bars
Gathering the right ingredients is the first step to creating these delightful bars. Here’s what you’ll need:
- Unsalted butter: Adds richness and moisture to the bars. Make sure it’s softened for easy mixing.
- Peanut butter: The star of the show! You can use creamy or crunchy, depending on your texture preference.
- Light brown sugar: This sweetener gives a lovely caramel flavor and helps keep the bars moist.
- Vanilla extract: A splash of vanilla enhances the overall flavor, making it more aromatic.
- Eggs: They act as a binder, helping to hold everything together while adding moisture.
- Quick-cooking oats: These provide a hearty texture and are essential for that oatmeal goodness.
- Baking powder and baking soda: These leavening agents help the bars rise, giving them a light and fluffy texture.
- Mashed ripe bananas: The key to natural sweetness! Overripe bananas work best, as they’re sweeter and easier to mash.
- Chocolate chips: Because who can resist chocolate? They add a delightful burst of sweetness in every bite.
For the streusel topping, you’ll need:
- Peanut butter: Again, this adds flavor and richness to the crumbly topping.
- Light brown sugar: Just like in the bars, it adds sweetness and a hint of caramel flavor.
- Quick-cooking oats: These create that perfect crumbly texture for the streusel.

How to Make Peanut Butter Oatmeal Banana Bread Bars
Step 1: Preheat the Oven and Prepare the Baking Dish
First things first, preheat your oven to 350°F (175°C). This step is crucial because it ensures even baking. While the oven warms up, grease your baking dish. I like to use a bit of butter or cooking spray to prevent sticking. A well-prepared dish makes all the difference in achieving those perfect bars!
Step 2: Cream Together Butter and Peanut Butter
In a large bowl, combine the softened butter and peanut butter. Using a hand mixer or a sturdy spoon, cream them together until smooth and fluffy. This process incorporates air, giving your bars a light texture. Trust me, the creaminess of the peanut butter will make your bars irresistible!
Step 3: Add Vanilla and Eggs
Next, add the vanilla extract and eggs to the creamed mixture. Mix until everything is well combined. The vanilla adds a warm aroma, while the eggs bind the ingredients together. This step is essential for creating a cohesive batter that holds up beautifully when baked.
Step 4: Combine Dry Ingredients
In another bowl, mix together the quick-cooking oats, baking powder, and baking soda. This is where the magic begins! The oats provide that hearty texture, while the baking powder and soda help the bars rise. Make sure to whisk them well to evenly distribute the leavening agents.
Step 5: Mix Wet and Dry Ingredients
Now, it’s time to combine the wet and dry ingredients. Gradually add the dry mixture to the wet ingredients, stirring gently. Be careful not to overmix; you want to keep that lovely texture. Just mix until everything is combined, and you’ll be on your way to delicious peanut butter banana bars!
Step 6: Fold in Bananas and Chocolate Chips
Here comes the fun part! Gently fold in the mashed bananas and chocolate chips. Folding is a technique that helps maintain the airiness of the batter. You want those sweet chunks of banana and chocolate to be evenly distributed without deflating your mixture. It’s like a little surprise in every bite!
Step 7: Pour Batter into Baking Dish
Pour the batter into your prepared baking dish, spreading it evenly. This ensures that your bars bake uniformly. I like to use a spatula to smooth the top. A well-spread batter leads to consistent baking, so take a moment to get it just right!
Step 8: Prepare the Streusel Topping
In a separate bowl, mix together the ingredients for the streusel topping. Combine the peanut butter, light brown sugar, quick-cooking oats, and chocolate chips until crumbly. You want a texture that resembles coarse sand. This topping adds a delightful crunch and extra flavor to your bars!
Step 9: Bake the Bars
Now, it’s time to bake! Place your dish in the preheated oven and bake for 25-30 minutes. Keep an eye on them! You’ll know they’re done when a toothpick inserted in the center comes out clean. The aroma wafting through your kitchen will be heavenly!
Step 10: Cool and Cut into Bars
Once baked, remove the dish from the oven and let it cool for a bit. This cooling period is essential for the bars to set properly. After about 10-15 minutes, cut them into squares. For neat bars, use a sharp knife and wipe it clean between cuts. Enjoy your delicious Peanut Butter Oatmeal Chocolate Chip Banana Bread Bars!

Tips for Success
- Use overripe bananas for maximum sweetness and flavor.
- Don’t skip the creaming step; it’s key for a light texture.

- Measuring cups and spoons: Essential for accuracy; you can use any standard measuring tools.
