How to Make Banana Oatmeal Bars
Step 1: Preheat Your Oven
Let’s get started by preheating your oven to 350°F (175°C) and lining a 9×9-inch baking pan with parchment paper for easy removal later.
Step 2: Mash Those Bananas!
In a large mixing bowl, mash the bananas until smooth, that lovely sweet aroma will fill your kitchen! You want them creamy with just a few lumps to keep things interesting. It should take about 2-3 minutes of mashing.
Step 3: Mix It All Together
Add the nut butter, rolled oats, cinnamon, vanilla extract, maple syrup, chocolate chips, and salt into the bowl with the bananas. Mix everything together until combined and sticky. You’ll know it’s done when it looks like a thick, hearty mixture, this part is so satisfying!
Step 4: Transfer to Baking Pan
Pour this delicious mixture into your prepared baking pan and spread it out evenly. Use a spatula or your hands to flatten it down into a nice, even layer. If you’re feeling extra decadent, sprinkle some more chocolate chips on top!
Step 5: Bake It Up!
Pop the pan in the oven and bake for 18 to 20 minutes or until the edges are golden brown and the center feels set. Trust me, the smell wafting through your kitchen will have everyone asking, “When are they done?!” Once baked, remove from the oven and let cool completely on a wire rack before cutting into bars.
