Three bananas have been sitting on your counter for a week, the peels have gone from spotty to nearly black, and you’re out of time to make a loaf. That’s exactly the moment these banana bread chocolate chip cookies were built for.
They taste like the crackly top edge of a banana bread loaf, the part everyone quietly fights over, except every bite has melted chocolate running through it. The centers stay soft and a little dense, the rims turn chewy, and they don’t puff into sad little muffin tops the way most banana cookies do.
That cakey-cookie problem is the whole reason this recipe exists. Below you’ll find the ratio that keeps the crumb chewy, the banana ripeness window that matters more than you’d guess, a chill time backed by real test-kitchen data, and one food-safety detail about banana cookie dough that almost nobody mentions. Go dig out your ugliest bananas.
Why These Banana Bread Chocolate Chip Cookies Work
A banana is roughly three-quarters water. When you mash half a cup of it into cookie dough, you aren’t just adding flavor, you’re adding liquid, and liquid plus leavening is how you get cake. Most banana cookie recipes fail right there: they call for two or three bananas, keep the flour where a normal chocolate chip cookie would have it, and the result rises, sets, then settles into something soft and bready.
This recipe uses one large banana, about half a cup mashed, against two full cups of flour. That single change does most of the work.
The rest comes down to three choices. Melted butter instead of creamed butter means less air beaten into the dough, so the cookies bake flatter and chewier instead of lifting. A heavy lean toward brown sugar brings molasses, which holds onto moisture and keeps day-three cookies from drying out. And the leavening is deliberately light, half a teaspoon of baking soda plus a quarter teaspoon of baking powder, roughly half what a banana bread loaf would want. You need just enough lift to keep the middles tender, not enough to inflate them.
An extra egg yolk finishes the job. The yolk adds fat and emulsifiers without the extra water a whole egg contributes, which is the same trick behind our oatmeal chocolate chip cookies and their chewy, never-cakey crumb.
Ingredients You’ll Need
Nothing here is unusual, but a couple of the weights matter more than the volume measurements. If you own a kitchen scale, use it for the flour and the banana.
For the Cookie Dough
| Ingredient | Amount | Why It Matters |
|---|---|---|
| Unsalted butter, melted and cooled | 1/2 cup (113 g) | Melted, not creamed, keeps the cookies chewy instead of puffy |
| Light brown sugar, packed | 3/4 cup (160 g) | Molasses holds moisture and deepens the banana flavor |
| Granulated sugar | 1/4 cup (50 g) | Crisps the edges and helps the tops crack |
| Large egg, room temperature | 1 | Structure and richness |
| Large egg yolk | 1 | Fat and emulsifiers without the extra water |
| Very ripe banana, mashed | 1/2 cup (120 g), about 1 large | The flavor engine, and the main source of liquid |
| Vanilla extract | 2 tsp | Rounds out the banana |
| All-purpose flour | 2 cups (240 g) | Enough to absorb the banana without drying the crumb |
| Baking soda | 1/2 tsp | Light lift and better browning |
| Baking powder | 1/4 tsp | Just enough to keep the centers tender |
| Fine sea salt | 3/4 tsp | Keeps the cookies from tasting flat |
| Ground cinnamon | 1/2 tsp | Optional, but it makes them read as banana bread |
For the Mix-Ins
| Mix-In | Amount | Notes |
|---|---|---|
| Semisweet chocolate chips | 1 1/2 cups (255 g) | Semisweet cuts the banana’s sweetness better than milk chocolate |
| Chopped walnuts or pecans, toasted | 3/4 cup (85 g), optional | Toast them first or they taste raw against the fruit |
| Flaky sea salt | A pinch per cookie, optional | Sprinkle on the mounds just before baking |
About that banana: you want it ugly. King Arthur Baking’s test kitchen puts it plainly, that the blacker the peel, the sweeter and more assertive the flavor, and there is essentially no such thing as too ripe unless the fruit has started to rot. A yellow banana with a few freckles will technically work, but it tastes faintly of nothing. Soft and streaked with black is the target. Frozen and thawed bananas are even better, since thawing breaks the cells down and the fruit squeezes out of the peel like toothpaste.
How to Make Banana Bread Chocolate Chip Cookies
Hands-on time runs about twenty minutes, plus a chill you shouldn’t negotiate with.
Step 1: Prep the Banana and Butter
- Melt the butter and set it aside for 10 minutes. Warm is fine. Hot butter will scramble your egg.
- Mash the banana in a small bowl with a fork until it’s mostly smooth with a few small lumps left. Measure after mashing, not before.
- Whisk the flour, baking soda, baking powder, salt, and cinnamon together in a medium bowl.
Step 2: Build the Dough
- In a large bowl, whisk the cooled melted butter with both sugars for about 30 seconds, until the mixture looks glossy and slightly paler.
- Whisk in the egg, the extra yolk, and the vanilla until smooth.
- Add the mashed banana and whisk just until combined. The mixture will look loose and faintly curdled, which is normal.
- Switch to a spatula and fold in the dry ingredients until no dry flour is visible. Stop there, because overmixing builds gluten and toughens the cookies.
- Fold in the chocolate chips and nuts. The dough will be soft and sticky, closer to a thick batter than a stiff cookie dough.
Step 3: Chill the Dough
- Cover the bowl and refrigerate for at least 45 minutes, or up to 72 hours.
- If you chill longer than a couple of hours, let the dough sit out for 15 minutes before scooping so it’s workable.
Chilling isn’t a stylistic preference here. King Arthur ran a ten-day chilling experiment and found that even 30 minutes in the fridge noticeably reduced spread and shifted the texture from soft and doughy to properly chewy, with flavor continuing to improve over the following days. Banana dough starts out wetter than standard cookie dough, so it needs that firming up more than most.
Step 4: Scoop and Bake
- Heat the oven to 350°F (175°C) and line two baking sheets with parchment.
- Scoop 2-tablespoon mounds and space them about 2 inches apart, roughly 12 per sheet.
- Bake one sheet at a time for 11 to 13 minutes, until the edges are set and lightly golden and the centers still look slightly underdone.
- Sprinkle with flaky salt if you’re using it, then let the cookies sit on the hot sheet for 5 minutes before moving them to a rack. They finish cooking there.
One Safety Rule Banana Cookie Recipes Skip
This dough tastes like banana bread batter, which makes it dangerously snackable. Resist it.
Flour is a raw agricultural product. The grain it’s milled from can carry Salmonella and pathogenic E. coli, and milling doesn’t kill either one. The FDA is direct about this: never eat or taste raw flour, dough, or batter, and home heat treatments aren’t reliable enough to make it safe. Since 2009, raw flour outbreaks in the United States have been linked to 168 illnesses and 20 hospitalizations. The raw egg and yolk in this bowl give you a second reason to keep the spoon out of your mouth.
If you want something spoonable, make a separate edible-dough batch with heat-treated flour and no eggs rather than repurposing this one. One more banana-specific note: if the fruit has visible mold or smells fermented and boozy instead of sweet, throw it out rather than trimming around it. Soft fruit lets mold spread well past the part you can see.
Tips for Soft, Chewy Banana Bread Chocolate Chip Cookies
- Weigh the banana after mashing. One banana ranges from 90 to 150 grams depending on size, and 60 extra grams of liquid is the whole difference between chewy and cakey.
- Underbake by a minute. The centers should look glossy and slightly wet when the sheet comes out. Carryover heat handles the rest.
- Bake one sheet at a time on the middle rack. Two sheets means uneven heat, and banana cookies brown unevenly to begin with.
- Bang the sheet once at the 9-minute mark if you want flatter, chewier cookies with rippled edges.
- Stick with parchment. Greased pans encourage spread, and silicone mats slow down browning on the bottoms.
- Cool them fully before stacking. Warm banana cookies are fragile and will glue themselves together.
If your first sheet still spreads more than you’d like, chill the scooped dough balls for 20 minutes before the next batch goes in.
Variations and Dietary Swaps
| Variation | What to Change | Notes |
|---|---|---|
| Gluten-free | Swap the flour 1:1 for a cup-for-cup blend containing xanthan gum | Chill the full 45 minutes, since GF dough needs it even more |
| Dairy-free | Use a firm vegan baking stick and dairy-free chips | Skip soft tub spreads, they carry too much water |
| Egg-free | Replace the egg and yolk with 3 tbsp extra mashed banana plus 1 tbsp cornstarch | Slightly denser, still chewy |
| Lower sugar | Cut the granulated sugar to 2 tbsp | Edges come out softer and less crisp |
| Bigger banana flavor | Whisk 2 tsp freeze-dried banana powder into the dry ingredients | Adds flavor without the water more fresh banana would bring |
| Brown butter | Brown the butter, cool it to room temperature, then whisk 1 tbsp water back in | Nutty depth, and the water replaces what evaporated |
| Peanut butter swirl | Dollop 1/2 tsp warmed peanut butter on each mound before baking | Same pairing that carries our peanut butter chocolate chip cookies |
Whole wheat flour works for up to half the total. Push past that and the cookies turn dry and dense quickly.
How to Store Banana Bread Chocolate Chip Cookies
These hold moisture well, which cuts both ways. They stay soft for days, and they also lose their crisp edges faster than a standard chocolate chip cookie.
| Method | How to Do It | How Long |
|---|---|---|
| Room temperature | Airtight container with a slice of sandwich bread tucked in | Up to 3 days |
| Refrigerator | Airtight container, layers separated by parchment | Up to 1 week |
| Freezer, baked | Cool completely, wrap in pairs, then bag | Up to 3 months |
| Freezer, raw dough | Freeze scooped mounds solid on a tray, then transfer to a bag | Up to 3 months |
| Refrigerated raw dough | Covered bowl, back of the fridge | Up to 72 hours |
Bake frozen dough balls straight from the freezer and add 2 to 3 minutes. For any refrigerated storage, keep the fridge at 40°F (4°C) or below. The FDA points out that many home refrigerators run warmer than their owners assume, and an appliance thermometer is the only way to actually know. Treat the raw dough like what it is: covered, cold, and never sampled.
Serving Suggestions
Warm, these are close to perfect with cold milk or a flat white. Espresso bitterness cuts the banana’s sweetness in a way filter coffee doesn’t quite manage.
A few other ways they earn their keep: sandwich two around a scoop of vanilla or salted caramel ice cream and freeze for 20 minutes; crumble one over Greek yogurt with a spoonful of peanut butter for a breakfast that’s barely pretending to be one; or serve them slightly warm alongside roasted strawberries. They also travel better than anything frosted, which makes them a smart bake-sale and lunchbox cookie.

Banana Bread Chocolate Chip Cookies FAQ
Why did my banana bread chocolate chip cookies turn out cakey?
Almost always too much banana. Half a cup mashed is the ceiling for two cups of flour, and a second banana pushes the dough into quick-bread territory. The other two culprits are creamed butter, which beats air into the dough, and a heavy hand with the baking soda or powder. Measure the banana by weight, use melted butter, and keep the leavening light.
Can I use frozen bananas for banana bread chocolate chip cookies?
Yes, and they’re arguably better. Thaw them completely in a bowl, then pour off the liquid that separates out before mashing, because that liquid is exactly the water you don’t want in the dough. Squeeze the fruit from the peel and measure your half cup from what’s left.
Do I really have to chill the dough?
For this recipe, yes. Banana dough starts out wetter than standard cookie dough, so unchilled scoops spread into thin, greasy discs. Forty-five minutes is the minimum that works reliably, and longer improves both texture and flavor.
Is it safe to taste banana bread chocolate chip cookie dough?
No. The dough contains raw flour and raw egg, and the FDA advises against eating or tasting any raw dough or batter because flour can carry Salmonella and E. coli that milling doesn’t remove. Bake it first. If you want a spoonable version, make a dedicated edible cookie dough with heat-treated flour and no egg.
How do I keep the chocolate chips from sinking?
Hold back about a quarter cup of chips and press them into the tops of the dough mounds right before baking. It fixes the look and guarantees visible chocolate on every cookie. If chips are sinking throughout the whole batch, your dough is too warm, so give it another 15 minutes in the fridge.
