Bite into a wonderfully moist, honey-colored treat that blends the nostalgic taste of banana bread with a blondie's delightful chew. These banana chocolate chip squares turn those spotty bananas into something you can't put down, filling your home with mouthwatering smells. When rich dark chocolate meets sweet banana, you get that perfect mix – soft yet substantial with every mouthful.
I've whipped these up tons of times, and they always vanish within a couple of hours at family events. My sister's kids especially enjoy squashing the bananas, and I love seeing how excited they get when the baking smell hits their noses.
Key Ingredients and Selection Advice
- Ripe bananas: Go for ones with dark freckles all over; they're sweeter and mash up way easier
- Light brown sugar: Its molasses gives you richer caramel hints and keeps everything perfectly moist
- Mini chocolate chips: The tiny size spreads through the mix better, so you taste chocolate in every single bite
- Unsalted butter: This lets you decide how much salt goes in; always pick fresh for best taste
- Pure vanilla extract: Spring for the real stuff; it really brings out both the banana and chocolate flavors
Step-By-Step Guide
- Step 1:
- Get your oven hot at 350°F (177°C). Put parchment in your 8x8 inch pan, letting some hang over the edges so you can lift the bars out later.
- Step 2:
- Melt your butter using short 15-second bursts in the microwave, giving it a stir between zaps. You want it just melted and slightly warm, not hot enough to burn you.
- Step 3:
- Mix all dry stuff together so your raising agents spread out evenly. Use a whisk to break up any flour lumps.
- Step 4:
- Mix your cooled melted butter with brown sugar. Keep whisking until it looks lighter and gets a bit thicker.
- Step 5:
- Throw in your room temp egg, mashed bananas, and vanilla into your butter mix. Whisk until it's all combined. 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 chips, but save 2 tablespoons for the top. Spread your mix flat in the pan and sprinkle those saved chips on top.
- Step 8:
- Bake for 30-35 minutes until the sides turn golden and the middle looks set but still feels a bit soft. A toothpick stuck near the center 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 way you'll get clean slices without crumbs going everywhere.

When I was little, my nana always told me bananas were the perfect food from nature. She'd bake these treats with dark chocolate, saying it made them "almost a health food." I can't back up that claim, but they've definitely become my favorite way to use up those overly spotted bananas.
Customizing Your Creation
What's great about this mix is how easy it is to change up. Try throwing in chopped walnuts for some crunch, or switch to dark chocolate chips for a grown-up flavor. Some relatives of mine even swirl in cream cheese when they're making them for special times.
Keeping Them Fresh
These squares stay wonderfully moist when you store them right. Just pop them in an airtight container with wax paper between layers. They'll keep well at room temp for 3-4 days, though in most homes they don't stick around nearly that long.
Watch Your Temperatures
How well these bars turn out often comes down to ingredient temps. Eggs at room temperature mix in much better, and letting your melted butter cool stops the chocolate chips from turning into a melty mess in your batter.

After making these countless times for family get-togethers, potlucks, and lazy Sunday afternoons, I can tell you these bars hit that sweet spot between comfort food and special treat. The recipe forgives small mistakes, making it great for new bakers and old pros looking for something everyone will gobble up.
