When life hands you overripe bananas, bake up some Peanut Butter Oatmeal Chocolate Chip Banana Bread Bars with Peanut Butter Oat Streusel. Whew, that’s a mouthful! A delicious, chewy, chocolatey mouthful.
No Such Thing as a Bad Banana
I cannot even look at these photos without my mouth watering. Friends, these banana bread bars are everything. They’re sweet, chewy, dense, and y’all, I’m not even over here pretending they are a healthier version of anything 😂. Made with butter, brown sugar, and lots and lots of love, they disappear as fast as you can serve them up.
It all began one morning with a bunch of very ripe bananas. Never one to let a squishy banana go to waste, I decided to whip up something new. Something dreamy. And these Peanut Butter Oatmeal Chocolate Chip Banana Bread Bars with a Peanut Butter Oat Streusel are a dream come true!
First, a quick tip! People ask me all the time how they’ll know if a banana is ripe enough for baking. Do your bananas look gross? Like, really gross? Then they’re ready! The more ripe a banana, the sweeter the batter. In a pinch, you can ‘ripen’ bananas in your oven. Simply place them on a baking sheet and then bake for 30 minutes or so in a 300°F oven. Keep in mind, though, that oven-ripened bananas don’t quite have the same sweetness to them.
Banana Bread Bar Batter (Say THAT Three Times Fast!)
To make the batter, first, cream the butter, peanut butter, and brown sugar together in the bowl of an electric stand mixer until light and fluffy. Next, add your eggs, one at a time, beating well after each addition. Then, beat in the vanilla.
In a separate bowl, whisk together the oats, baking powder, and baking soda. Next, add the oat mixture to the ingredients in the stand mixer and beat on low to medium speed until well combined. Finally, fold in the mashed banana and then 1 cup of chocolate chips.
Streusel, Bake, Eat
To make the streusel, first stir the peanut butter, brown sugar, and oats together in a small bowl with a fork until crumbly. Next, gently mix in 1/2 cup chocolate chips. After spreading the bread batter evenly into a prepared baking pan, sprinkle the streusel evenly over the batter. There you have it!
Bake at 350°F for 40-45 minutes, or until a toothpick inserted near the center comes out clean.
I admit that waiting for these beauties to bake requires a lot of patience. And letting them cool for 15 minutes feels like a Herculean task. But I promise they’re worth the wait!
Finally, once cooled at least 15 minutes, cut the bread into bars and enjoy a bit of chewy chocolatey heaven. Supposedly, this recipe makes 24 servings, but I’ll let y’all be the judge of that.
Serve and enjoy! Your crew will devour these treats before you can say, “Peanut Butter Oatmeal Chocolate Chip Banana Bread Bars with a Peanut Butter Oat Streusel!”
