Bite into a deliciously moist, honey-colored bar that brings together the homey feel of banana bread with the gooey satisfaction of a blondie. These banana chocolate chip squares turn those spotty bananas into a mouthwatering snack that sends wonderful smells throughout your home. The mix of rich dark chocolate chips and sweet bananas creates something that's soft yet fulfilling with each mouthful.
I've whipped these up too many times to count, and they always vanish within minutes at family parties. My little nieces can't wait to squish the bananas, and I love watching their faces light up when they catch a whiff of these squares baking.
Key Components and Selection Advice
- Spotted bananas: Go for ones with brown speckles all over; they're way sweeter and mash up easier
- Light brown sugar: Its molasses bits add rich caramel hints and keep everything nice and moist
- Mini chocolate chips: The tiny size spreads better through the mix, so you get chocolate in every single bite
- Unsalted butter: This lets you manage how salty things get; always pick fresh for best taste
- Real vanilla extract: Don't cut corners here; good vanilla makes both the banana and chocolate taste even better
Step-by-Step Cooking Guide
- Step 1:
- Get your oven warming to 350°F (177°C). Take your 8x8 inch baking dish and put parchment paper in it, letting some hang over the edges so you can lift everything out later.
- Step 2:
- Melt your butter using quick 15-second zaps in the microwave, giving it a stir between zaps. You want it just melted and slightly warm when touched, not hot.
- Step 3:
- Mix all your dry stuff together to spread out the baking powder and soda. Use a whisk to break down any flour lumps.
- Step 4:
- Mix your cooled melted butter with the brown sugar. Keep whisking until it looks lighter and gets a bit thicker.
- Step 5:
- Throw in your room-temp egg, mushed bananas, and vanilla into the butter mix. Whisk until everything's mixed up. Don't worry if it looks a bit lumpy now.
- Step 6:
- Slowly fold in the flour mixture with a spatula until you can't see any dry flour. Don't mix too much or your bars won't be soft.
- Step 7:
- Fold in most of your mini chocolate chips, but save 2 tablespoons for the top. Spread the mix evenly in your pan and sprinkle those saved chips on top.
- Step 8:
- Bake for 30-35 minutes until the sides turn golden and the middle feels firm but slightly soft. Stick a toothpick in near the center – it should come out with a few moist crumbs.
- Step 9:
- Let the bars cool completely in the pan on a wire rack before cutting. This helps you get nice clean slices.

When I was little, my grandma always told me bananas were the perfect food from nature. She'd bake these bars with dark chocolate and joke they were "almost like eating health food." While I can't back up that claim, I can tell you they've become my favorite way to use up browning bananas.
Customizing Your Creation
What's great about this mix is how easily you can change it up. Try adding chopped walnuts for some crunch, or switch to dark chocolate chips for a grown-up taste. Some of my relatives even swirl in cream cheese when we're celebrating something special.
Keeping Them Fresh
These bars stay wonderfully moist when you store them right. Just put them in a sealed container with wax paper between layers. They'll be good at room temperature for 3-4 days, though in my house they rarely stick around that long.
Watch Your Temperatures
How these turn out often comes down to ingredient temps. Eggs at room temperature blend in better, and letting your melted butter cool down keeps the chocolate chips from melting too soon in the batter.

After making these countless times for family get-togethers, potlucks, and lazy Sunday afternoons, I can honestly say these bars hit the sweet spot between comfort food and special treat. The forgiving nature of this mix makes it great for kitchen beginners and seasoned bakers looking for something that'll make everyone happy.
