Bite into a soft, caramel-colored treat that blends the homey taste of banana bread with the gooey goodness of a blondie. These banana chocolate chip squares turn those spotty bananas into something you can't put down, filling your home with amazing smells. When dark chocolate meets sweet banana, you get something that's both soft and satisfying with each mouthful.
I've whipped these up so many times, and they're always gone within the day when family comes over. My sister's kids especially can't wait to squash the bananas, and I love seeing how their faces light up when the baking smell hits them.
Key Components and Selection Advice
- Spotted bananas: Go for ones with dark speckles all over; they're sweeter and mash up easier
- Light brown sugar: Gives you that rich caramel flavor and keeps everything nice and moist
- Mini chocolate chips: The tiny size spreads throughout the mix better, so you get chocolate in every bite
- Unsalted butter: Lets you add just the right amount of salt yourself; always pick fresh for best taste
- Real vanilla extract: Worth spending a bit more on the genuine stuff; it makes both the banana and chocolate taste even better
Step-by-Step Process
- Step 1:
- Get your oven hot at 350°F (177°C). Put parchment in your 8x8 inch pan with some hanging over so you can lift the bars out later.
- Step 2:
- Melt your butter in the microwave using short 15-second bursts, giving it a stir between each. You want it just melted and slightly warm, not bubbling hot.
- Step 3:
- Mix all your dry stuff together to spread out the baking agents. Use a whisk to break down any flour lumps.
- Step 4:
- Mix your cooled melted butter with the brown sugar. Keep whisking until it gets lighter and a bit thicker.
- Step 5:
- Put in your room-temp egg, mashed bananas, and vanilla with the butter mix. Whisk until it's all combined. Don't worry if it looks a bit lumpy right now.
- Step 6:
- Slowly add the flour mixture with a spatula until you can't see any dry spots. Don't mix too much or your bars won't be as soft.
- Step 7:
- Mix in most of your mini chocolate chips, but save about 2 tablespoons. Spread everything flat in the pan and sprinkle those saved chips on top.
- Step 8:
- Bake them for 30-35 minutes until the sides turn golden and the middle feels set but still a little soft. If you poke it with a toothpick, it should come out with some moist crumbs.
- Step 9:
- Let the whole thing cool completely in the pan on a wire rack before you cut it. This helps you get clean slices.

When I was little, my grandma always told me bananas were the perfect food from nature. She'd throw in dark chocolate and joke they were "almost healthy." I can't say if that's true, but they've become my favorite way to use up those overripe bananas.
Customizing Your Creation
What's great about this mix is how easy it is to change up. Try throwing in some chopped walnuts for extra crunch, or swap regular chips for dark chocolate ones if you want something fancier. Some of my relatives even swirl in cream cheese when they're making them for special events.
Keeping Them Fresh
These bars stay surprisingly moist when stored right. Just put them in a sealed container with wax paper between each layer. They'll be good on the counter for 3-4 days, though in my house they rarely last past the second day.
Watch Your Temperatures
How well these turn out often comes down to how warm your ingredients are. Eggs that have been sitting out mix in better, and butter that's cooled down properly won't melt your chocolate chips too early in the batter.

After making these so many times for family get-togethers, potlucks, and lazy weekends at home, I can tell you they hit that sweet spot between everyday snack and special treat. They're so forgiving that even if you're new to baking or a pro looking for something that'll make everyone happy, you can't go wrong.
