Chocolate Chip Banana Bars

Chocolate Chip Banana Bars are the perfect mash-up of classic banana bread and chewy blondies. They’re rich, buttery, and packed with sweet banana flavor, with pockets of melted chocolate in every bite. If you have a couple of overripe bananas sitting on your counter, this recipe is one of the most satisfying ways to use them up. Baked in an 8×8-inch pan, these bars come together quickly and slice beautifully, making them ideal for snacking, dessert, bake sales, or sharing with friends.

Unlike traditional banana bread, these bars have a denser, more dessert-like texture thanks to the creamed butter and brown sugar base. The result is tender and moist with lightly crisp edges and a soft, almost fudgy center. They truly taste like banana blondies—simple, comforting, and irresistibly good.

Ingredients Breakdown

These Chocolate Chip Banana Bars rely on classic baking ingredients, each playing an important role in flavor and texture. For best results, use the exact ingredients listed below.

Butter

• ½ cup (1 stick) unsalted butter, room temperature (113g)
  Butter adds richness and moisture. Make sure it’s soft enough to cream easily with the sugar.

Brown Sugar

• 1 cup packed light brown sugar (200g)
  Brown sugar provides sweetness and moisture, along with a subtle caramel flavor that pairs beautifully with bananas.

Egg

• 1 large egg, room temperature (56g)
  The egg binds the batter together and contributes to structure.

Vanilla

• 1½ teaspoons vanilla extract or vanilla bean paste (6g)
  Vanilla enhances both the banana and chocolate flavors.

Salt

• ½ teaspoon fine salt (3g)
  Salt balances sweetness and brings out the depth of flavor.

Flour

• 1 cup all-purpose flour (125g)
  This gives the bars structure without making them cakey.

Bananas

• 1 cup mashed overripe banana (about 2 large bananas, 250g)
  Overripe bananas are key. They should be heavily speckled or nearly black for maximum sweetness and moisture.

Chocolate Chips

• ¾ cup chocolate chips, chopped (125g)
  Use mini chocolate chips or chopped regular chips for more even distribution throughout the bars.

Equipment You’ll Need

• 8×8-inch light-colored metal baking pan
• Parchment paper
• Electric hand mixer or stand mixer
• Rubber spatula
• Mixing bowls
• Wire cooling rack

Step-by-Step Instructions

1. Prepare the Pan and Oven

Preheat your oven to 350°F (175°C). Line an 8×8-inch baking dish with parchment paper, leaving some overhang on the sides for easy removal. Lightly spray with cooking spray and set aside.

2. Cream Butter and Sugar

In a large bowl or the bowl of a stand mixer, combine the ½ cup unsalted butter and 1 cup brown sugar. Mix on medium-high speed for about 2 minutes, until the mixture looks lighter in color and slightly fluffy. This step helps create soft, tender bars.

3. Add Wet Ingredients

Add the 1 large egg, 1½ teaspoons vanilla extract, and ½ teaspoon fine salt. Mix on medium-low speed until fully combined. Scrape down the sides and bottom of the bowl as needed to ensure even mixing.

4. Incorporate the Flour

Add 1 cup all-purpose flour and mix on low speed until just combined. Be careful not to overmix, as this can make the bars dense.

5. Fold in the Bananas

Gently fold 1 cup mashed banana into the batter using a rubber spatula. The batter will become looser and very moist.

6. Add the Chocolate Chips

Fold in ¾ cup chocolate chips, reserving a small handful to sprinkle on top. Mixing them in by hand helps keep the batter tender.

7. Bake

Pour the batter into the prepared pan and smooth the top. Sprinkle the remaining chocolate chips over the surface.
Bake for 33–37 minutes, rotating the pan halfway through. The edges should be lightly golden, and the center should be set but still soft.

8. Cool and Slice

Remove the pan from the oven and let it cool completely on a wire rack. Once fully cooled, lift the bars out using the parchment paper and cut into 16 squares with a sharp knife. Wipe the knife between cuts for clean edges.

Pro Tips for Perfect Banana Bars

• Use very ripe bananas – The darker the peel, the sweeter the flavor.
• Room-temperature ingredients matter – This ensures a smooth, evenly mixed batter.
• Don’t overbake – Slightly underbaked centers stay moist as the bars cool.
• Metal pans work best – They bake more evenly than glass.
• Let them cool fully – Cutting too early can cause the bars to crumble.

Baking Pan Options

These bars bake best in a light-colored metal pan. If you’re using a glass baking dish, reduce the oven temperature to 325°F (165°C) and start checking for doneness about 5 minutes earlier. Glass heats more slowly but retains heat longer, which can lead to overbaked edges.

Variations and Customizations

While this recipe is delicious as written, here are a few easy ways to switch it up:

• Extra chocolatey – Add a few more chocolate chips on top after baking.
• Nutty crunch – Stir in chopped walnuts or pecans.
• Banana spice bars – Add a pinch of cinnamon to the batter.
• Dessert-style topping – Drizzle with melted chocolate once cooled.

Making These Bars in Advance

Chocolate Chip Banana Bars are an excellent make-ahead dessert.

• Room temperature: Store in an airtight container for up to 3 days.
• Refrigerator: Keeps well for up to 1 week.
• Freezer: Freeze for up to 1 month. Wrap bars individually and separate layers with parchment paper to prevent sticking.

To serve, thaw at room temperature or warm slightly for a fresh-baked feel.

Doubling the Recipe

This recipe can easily be doubled and baked in a 9×13-inch pan. Increase the baking time to 37–42 minutes, checking for doneness in the center. The edges should be golden, and the middle just set.
