These Banana Chocolate Chip Bars strike the perfect balance between banana bread and fudgy blondies, creating a treat that's wonderfully moist with an almost brownie-like texture. They're the ideal solution for those overripe bananas on your counter and a delicious change from traditional banana bread.

I discovered this recipe during a banana bread burnout phase, when I wanted something different but still banana-forward. These bars quickly became my new favorite banana treat!

Essential Ingredients and Selection Tips

  • Bananas: The riper, the better - look for heavily speckled or even black skins
  • Brown Sugar: Light brown sugar provides the perfect caramel notes
  • Butter: Softened completely for proper creaming, especially if mixing by hand
  • Chocolate Chips: Mini chips or chopped regular chips distribute more evenly
  • Vanilla Extract: A good quality extract enhances both the banana and chocolate flavors

Growing up, my grandmother always said the secret to baking with bananas is patience - waiting for them to get perfectly overripe creates the most flavorful results.

Banana Ripening Hack

No time to wait for bananas to ripen naturally? Place unpeeled bananas on a baking sheet and bake at 300°F for about 15 minutes until skins turn black. Cool for 10 minutes, then peel and mash.

After making these countless times, I've learned they're more than just a way to use up bananas - they're a versatile treat that's welcomed everywhere from lunchboxes to coffee dates. The combination of moist, banana-infused base studded with melty chocolate creates something truly special that banana bread lovers and blondie enthusiasts can equally appreciate.

Make-Ahead and Storage Strategies

These bars actually improve with time as the flavors meld together. Store them in an airtight container with parchment paper between layers to prevent sticking. They'll keep at room temperature for 3 days, in the refrigerator for up to a week, or in the freezer for a month. For frozen bars, thaw individual pieces at room temperature for about 30 minutes before enjoying. I often make a double batch and freeze half for future snack emergencies!

Creative Flavor Variations

While the classic version is wonderful, try these delicious alternatives:

  • Add 1/2 teaspoon of cinnamon and 1/4 teaspoon of nutmeg for a warm, spiced version
  • Swap half the chocolate chips for butterscotch chips for a caramel-like flavor
  • Mix in 1/2 cup chopped walnuts or pecans for a delightful crunch
  • Add 1/4 cup shredded coconut for a tropical twist
  • Drizzle cooled bars with a simple powdered sugar glaze for extra sweetness

Troubleshooting Common Issues

If your bars turn out too dense, you likely overmixed the batter after adding the flour. Next time, use a gentle folding motion and stop as soon as the flour disappears. If they're too gooey in the center, they may need a few more minutes in the oven - cover loosely with foil if the edges are browning too quickly. And if your chocolate chips sink to the bottom, try tossing them in a tablespoon of flour before adding to the batter.

Perfect Texture Guide

These bars should have a texture that's different from both cake and cookies - somewhere in between with a fudgy, moist quality. The key is baking them just until a toothpick inserted in the center comes out with a few moist crumbs (not wet batter). They'll continue to set as they cool, so it's better to slightly underbake than overbake them.

After years of refining this recipe, I've come to appreciate how these bars represent the perfect balance between effort and reward. They're simple enough for baking beginners but delicious enough to impress anyone. There's something deeply satisfying about transforming those spotty bananas that might otherwise be wasted into something so crave-worthy.

Whether packed in lunchboxes, served with afternoon tea, or enjoyed as a midnight snack, these banana chocolate chip bars bring comfort and joy in each bite. They're the kind of homemade treat that creates memories and becomes a requested favorite for years to come.

Recipe Tips & Questions

→ Can I use frozen bananas?
Yes, thaw frozen bananas completely and drain excess liquid before mashing. They work perfectly in this recipe.
→ How ripe should my bananas be?
Very ripe bananas with lots of brown spots are best - they're sweeter, easier to mash, and give the best flavor.
→ Can I add nuts to this recipe?
Absolutely! Add 1/2 cup of chopped walnuts or pecans along with or instead of some of the chocolate chips.
→ What if I don't have an 8x8 pan?
You can use a 9-inch round pan with similar results. For a 9x13 pan, double the recipe and bake 37-42 minutes.
→ How do I know when they're done baking?
The edges should be golden brown and the center should look set. A toothpick inserted into the center should come out with a few moist crumbs but no wet batter.

What You'll Need

→ Main Ingredients

01 1/2 cup unsalted butter, room temperature (113g)
02 1 cup packed light or dark brown sugar (200g)
03 1 large egg, room temperature (56g)
04 1 1/2 tsp vanilla extract (6g)
05 1/2 tsp fine salt (3g)
06 1 cup all-purpose flour (125g)
07 1 cup mashed overripe banana - about 2 large bananas (250g)
08 3/4 cup chocolate chips, chopped (125g)

Let's Cook!

Step 01

Preheat the oven to 350°F / 175°C. Line an 8x8-inch baking dish with parchment paper and spray with cooking spray. Set aside

Step 02

In a large bowl or the bowl of a stand mixer, cream together butter and brown sugar with a stand mixer or hand mixer. Mix on a medium-high speed for about 2 minutes, until the mixture becomes lighter in color

Step 03

Add in egg, vanilla extract, and salt. Mix on a medium-low speed until combined. Scrape the sides and bottom of the bowl as needed with a rubber spatula

Step 04

Mix in all-purpose flour and mix on low until just combined

Step 05

Fold mashed banana into the batter until fully incorporated. Then fold in chocolate chips, saving a few to sprinkle on top of the batter before baking

Step 06

Pour the batter into the prepared pan and sprinkle additional bits of chocolate on top. Bake for 33-37 minutes, until the edges are golden brown, and the center is baked through. Rotate the pan halfway through

Step 07

Remove the pan from the oven and let it cool on a wire rack. Let the bars fully cool in the pan

Step 08

Once cool, gently remove the bars from the pan and cut into 16 squares using a sharp, warm knife. Wipe the blade after each cut with a paper towel to get clean cuts
