This chocolate chip banana bars recipe makes about 24 soft, moist bars in a 13 x 9-inch pan. Made with very ripe bananas, softened butter, sugar, eggs, flour, and semisweet chocolate chips, the batter comes together in about 15 minutes and bakes at 350°F for 20–25 minutes.
Each bar has the comforting flavor of classic banana bread with a tender, brownie-like bite and pockets of melted chocolate throughout. They are sweet without being heavy, easy enough for a weekday bake, and ideal for lunch boxes, casual entertaining, or using the very ripe bananas on your counter.

These chocolate chip banana bars are the kind of homemade treat that disappears quickly. They combine the familiar comfort of banana bread with the easy serving style of a tray bake, so there is no need to wait for a loaf to cool completely before slicing individual portions.

This recipe is also wonderfully practical. It uses common pantry ingredients, requires just one mixing bowl plus a small bowl for the dry ingredients, and produces about 24 bars from one pan.

Ingredients You’ll Need
The ingredient list is short, but each item has an important job. Softened unsalted butter creams smoothly with the sugar, eggs add structure, and very ripe bananas provide moisture, natural sweetness, and the strongest banana flavor.
- Butter and sugar: Use softened butter rather than melted butter so the mixture becomes light and creamy during beating.
- Eggs and vanilla: Two large eggs help bind the batter, while vanilla rounds out the banana and chocolate flavors.
- Very ripe bananas: Choose bananas with plenty of brown spots. They should be soft enough to mash easily and fragrant when peeled.
- Flour, baking soda, and salt: These create the tender structure and keep the sweetness balanced.
- Chocolate chips: Semisweet chips provide a classic chocolate flavor that complements the fruit without overpowering it.
For an optional variation, fold in 1/2 cup chopped walnuts or pecans. A small pinch of cinnamon is also welcome if you like a gently spiced banana dessert.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C), then prepare a 13 x 9-inch baking pan by greasing it or lining it with parchment. Parchment makes it especially easy to lift the cooled bars out for neat cutting.
Step 2: Place the softened butter and granulated sugar in a large bowl. Beat them for about 2–3 minutes, until the mixture looks lighter, creamy, and smooth rather than dense.
Step 3: Add the eggs one at a time, beating after each addition. Mix in the vanilla extract, scraping the sides of the bowl if needed so the ingredients are evenly distributed.
Step 4: Stir in the mashed bananas. The mixture may look slightly soft or curdled at this point, but that is normal and will come together once the dry ingredients are added.
Step 5: In a separate bowl, whisk the all-purpose flour, baking soda, and salt together. This distributes the leavening and salt before they enter the wet mixture.
Step 6: Gradually add the dry ingredients to the banana mixture. Mix only until no dry streaks remain; the batter should be thicker than cake batter but softer than cookie dough.
Step 7: Fold in the semisweet chocolate chips with a spatula. Add the chopped walnuts or pecans and the optional pinch of cinnamon now, using gentle strokes to avoid overworking the batter.
Step 8: Transfer the batter to the prepared pan and spread it into an even layer. Pay attention to the corners because an even thickness helps all the bars finish baking at the same time.
Step 9: Bake for 20–25 minutes. The center should be set, and a toothpick inserted into a plain area should come out with a few moist crumbs; avoid testing directly through a melted chocolate chip.
Step 10: Let the bars cool in the pan for 10–20 minutes before slicing. Cooling gives the tender crumb time to settle and makes cleaner cuts possible.
Pro Tips for Moist Banana Bars
The bananas are the main source of flavor, so do not rush this recipe with firm, pale yellow fruit if you can avoid it. Heavily spotted bananas are sweeter, softer, and more aromatic, which makes the finished bars taste naturally rich.
Measure the mashed bananas after peeling and mashing. About 1 cup from 2–3 medium bananas is the target, and keeping close to that amount helps preserve the intended moisture and consistency.
Take care when adding the flour. Overmixing develops gluten and can make the bars less tender, so stop as soon as the last dry streak disappears.
- Bring the butter to room temperature so it beats smoothly with the sugar.
- Use parchment with a little overhang for easy lifting.
- Spread the batter evenly before baking.
- Begin checking at 20 minutes because ovens vary.
- Judge doneness by moist crumbs and a set center, not by a toothpick passing through chocolate.

Cooling, Cutting, and Serving
Although the bars smell irresistible when they leave the oven, cooling is part of the recipe. Allow them to rest in the pan for 10–20 minutes so the structure firms slightly while the chocolate remains pleasantly soft.
For tidy squares, use a sharp knife and wipe the blade between cuts. You can make about 24 smaller bars for sharing, or cut larger pieces when serving them as a plated dessert.
Serve the bars at room temperature for the softest texture. They are delicious on their own, but a small scoop of vanilla ice cream or a dusting of powdered sugar can make them feel extra special.
If you are planning a dessert tray, these bars pair nicely with delicate mini white chocolate cheesecakes.
Storage and Make-Ahead Advice
Store completely cooled banana bars in a covered container at room temperature for up to 3 days. Keeping them covered helps protect the moist texture and prevents the cut edges from drying out.
For longer storage, refrigerate the covered bars for about 5 days. Let individual pieces sit at room temperature briefly before serving if you prefer a softer crumb and more noticeable chocolate flavor.
These bars are convenient for preparing ahead because they cool quickly compared with a full loaf of banana bread. Once cooled, cut them into portions and arrange them in a single layer or separate layers with parchment.
