Chocolate Chip Banana Bread
Chocolate Chip Banana Bread That Isn’t Gummy in the Middle
Banana bread that sinks in the middle or stays gummy even after it looks done usually comes down to too much mashed banana relative to the flour, not an oven problem. The fix is measuring the bananas by weight rather than just by count, since banana size varies enough that “three bananas” can mean anywhere from 1 cup to nearly 2 cups of mashed fruit depending on what you grabbed at the store. This version also toasts the walnuts if you’re using them and folds the chocolate chips in with a bit of flour first, so they stay suspended through the batter instead of sinking straight to the bottom.
Why This Chocolate Chip Banana Bread Bakes Through Evenly
Measuring mashed banana by weight instead of by banana count means the fruit-to-flour ratio stays consistent every time, which is what actually prevents a gummy, underbaked center.
Browning the butter instead of just melting it adds a nutty depth that plain butter doesn’t bring, something that matters since banana flavor alone can taste one-note without it.
Tossing the chocolate chips in a spoonful of flour before folding them in keeps them distributed through the batter rather than settling in a dense layer at the bottom of the loaf.
Using very ripe, heavily spotted bananas rather than ones that are just barely yellow gives more concentrated sweetness, meaning less added sugar is needed to balance the loaf.
A foil tent added partway through baking keeps the top from over-browning before the center has fully set, a problem that shows up specifically in loaves this dense with mix-ins.
Quick Information
Prep time: 15 minutes. Cook time: 1 hour. Total time: 1 hour 15 minutes. Servings: 10 slices. Difficulty: Easy. Calories: about 290 per slice. The one thing that matters most here is measuring the banana by weight, since getting that ratio wrong is the single biggest reason this bread turns out gummy. Good for breakfast, an afternoon snack, or gifting during the holidays.
Ingredients
For the batter:
- 1 1/2 cups mashed ripe banana (about 350g, roughly 3 to 4 medium bananas depending on size)
- 1/2 cup unsalted butter
- 3/4 cup light brown sugar, packed
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 3/4 cups all-purpose flour
- 1 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 teaspoon ground cinnamon
- 1 1/4 cups semi-sweet chocolate chips, divided
- 1/2 cup chopped walnuts, toasted (optional)
Weighing the mashed banana rather than counting bananas removes the single biggest variable in this recipe, since a large banana can weigh nearly twice what a small one does.
Browning the butter until it smells faintly toasted and shows small brown flecks at the bottom of the pan builds a layer of flavor that banana alone doesn’t provide on its own.

Allergen and Dietary Disclosure
This recipe contains dairy (butter, most chocolate chips contain milk solids), egg, gluten (flour), and tree nuts (walnuts, optional). For a dairy-free version, a plant-based butter stick and dairy-free chocolate chips work as substitutes, though browned butter made with plant-based butter won’t develop quite the same depth. For gluten-free, a 1-to-1 gluten-free flour blend works well in this batter without major texture changes. For a nut-free version, simply omit the walnuts entirely, they’re genuinely optional here and the bread holds together the same without them.
Equipment Needed
A kitchen scale for weighing the mashed banana, this single tool matters more here than almost any other piece of equipment on this list. A 9×5 inch loaf pan, the standard size this recipe is built around. A light-colored saucepan for browning the butter, since a dark pan makes it hard to see the color change. A wire cooling rack, letting the loaf cool fully on a rack rather than in the pan prevents the bottom from turning soggy from trapped steam.
Nutrition Information
Calories: 290 per slice. Protein: 5g. Carbs: 38g. Fat: 14g. Fiber: 2g. Sugar: 22g. Sodium: 180mg. Serving size: 1 slice (1/10 of loaf). Servings per recipe: 10. This bread carries a moderate sugar content typical of a sweet quick bread, with a small fiber boost from the bananas and walnuts if used.

Why Banana Bread Turns Gummy in the Middle (And How Weighing the Fruit Fixes It)
Banana counts as a liquid ingredient in this kind of batter, and when there’s more of it than the recipe’s flour and leavening can structurally support, the center never fully sets even after an hour in the oven, it just stays dense and wet while the edges bake through normally. The problem is that “three bananas” is a wildly inconsistent measurement, a small banana might mash down to under a cup while three large ones can push past two cups, nearly 50% more liquid than the recipe was built to handle. Weighing the mashed banana to a specific gram amount removes that inconsistency entirely, so the same recipe behaves the same way every time regardless of what size bananas happened to be ripe that week.
Tossing the chocolate chips in flour before folding them into the batter matters here for a similar reason, since chips add weight the batter otherwise can’t hold evenly in suspension, and that light flour coating gives them just enough grip to stay distributed as the bread bakes.
Preparation
Weigh out the mashed banana before doing anything else, since it’s the ingredient most likely to throw off the whole recipe if measured loosely. Toast the walnuts in a dry skillet over medium heat for about 4 minutes, stirring often, if using, letting them cool before chopping. Preheat the oven to 350°F and grease the loaf pan, lining it with parchment paper that overhangs the sides slightly makes removing the finished loaf much easier later.
Step-by-Step Method
- Melt the butter in a light-colored saucepan over medium heat, swirling occasionally as it foams and then quiets, watching for small brown flecks to appear at the bottom, about 5 minutes total.
- Pour the browned butter into a large mixing bowl right away once you see those flecks and smell a nutty aroma, since it keeps cooking in the hot pan even after you remove it from the burner.
- Let the butter cool for about 5 minutes, then whisk in the brown sugar until the mixture looks grainy and well combined, that texture is expected at this stage.
- Add the weighed mashed banana, eggs, and vanilla, whisking until the mixture turns smooth and uniform with no streaks of egg remaining.
- In a separate bowl, whisk together the flour, baking soda, salt, and cinnamon until evenly distributed throughout.
- Fold the dry ingredients into the wet mixture using a spatula, stirring just until no dry flour streaks remain, overmixing here develops gluten the recipe doesn’t need and leads to a tougher crumb.
- Toss 1 cup of the chocolate chips with a teaspoon of flour taken from the measured amount, then fold them into the batter along with the toasted walnuts if using.
- Pour the batter into the prepared loaf pan, smoothing the top with a spatula, then scatter the remaining 1/4 cup chocolate chips over the surface for visual appeal.
- Bake at 350°F for 55 to 65 minutes, checking at the 40-minute mark. If the top is browning quickly while the center clearly still needs more time, tent the pan loosely with foil for the remainder of the bake.
- Test doneness with a toothpick inserted into the thickest part of the loaf, it should come out with a few moist crumbs clinging to it, not wet batter, and not completely dry either.
- Let the loaf cool in the pan for 15 minutes before lifting it out using the parchment overhang, then transfer it to a wire rack to finish cooling completely before slicing.
Chef’s Note: If your loaf sinks in the middle after baking, the banana amount was probably too heavy for the batter, or it came out of the oven before the center fully set. Weigh the banana next time and give it the full bake time before testing.
Chef’s Note: Letting the loaf cool fully on a rack rather than slicing it warm matters more than it seems, since the crumb is still setting internally even after the oven time is done.
Chef’s Note: The step most people skip is tossing the chocolate chips in flour first. Without that light coating, the chips sink straight to the bottom third of the loaf instead of staying distributed throughout.

Expert Tips & Tricks
You can mash and weigh the banana a day ahead, storing it in the fridge in an airtight container, which also lets the banana continue ripening slightly for even more flavor.
Baked bread keeps well wrapped tightly at room temperature for up to 4 days, and the flavor actually deepens a bit by the second day as the spices settle in.
If your bananas aren’t ripe enough yet, baking them on a sheet pan at 300°F for about 15 minutes, until the skins turn fully black, softens and sweetens them enough to use right away.
Adding a tablespoon of sour cream or plain yogurt to the batter alongside the eggs gives a slightly more tender crumb, though it’s not required if you don’t have it on hand.
A sprinkle of flaky sea salt over the top before baking balances the sweetness of the chocolate chips without needing to change anything else in the recipe.
Doubling this recipe works best as two separate loaves rather than one giant loaf, since a single oversized loaf struggles to bake through evenly in the center.
Common Mistakes & Troubleshooting
Center stays gummy even after a full hour of baking. This almost always means there was too much mashed banana relative to the flour. Weigh the banana to the amount called for rather than estimating by banana count, which varies too much to be reliable.
Loaf sinks in the middle after cooling. Usually caused by underbaking, often from pulling the bread when the toothpick test still showed wet batter rather than a few moist crumbs. Give it the full bake time and test again before removing it from the oven.
Chocolate chips sink to the bottom of the loaf. This happens when chips go into the batter without any flour coating first. Toss them in a spoonful of flour before folding them in, which helps them grip the batter instead of settling straight down.
Top burns before the inside is fully baked. This can happen in ovens that run hot, or when the loaf bakes on a rack too close to the top heating element. Tent the pan loosely with foil once the top looks done, continuing to bake until the center sets.
Bread tastes bland despite the banana and chocolate. Old baking soda loses its leavening power over time, if yours has been open more than 6 months, a fresh box makes a noticeable difference in both rise and flavor.
Honest Trade-Off
Weighing the banana and toasting the walnuts adds a few extra minutes of prep compared to just mashing whatever bananas you have and tossing everything in without measuring precisely. The looser approach is faster for a casual weekend bake, it just risks the gummy-center problem if your bananas happen to run larger than average that week. Someone baking casually with no particular concern about precision might skip the scale and accept some variability; someone who wants consistent results every time should weigh the banana.
Storage & Make-Ahead
Wrap the cooled loaf tightly in plastic wrap and store at room temperature for up to 4 days. The texture holds up well, though the crust softens slightly by the later days compared to fresh out of the oven.
Freezing works well for up to 3 months, either as a whole wrapped loaf or pre-sliced with parchment between layers for grabbing individual pieces. Thaw at room temperature for a few hours, or microwave individual slices for about 20 seconds if you want it warm.
Variations & Substitutions
For a richer version, swap half the chocolate chips for chopped dark chocolate chunks, which melt into larger pockets throughout the loaf.
For a spiced variation, add 1/4 teaspoon ground nutmeg alongside the cinnamon for a warmer, more complex flavor.
For a lighter version, swap half the butter for unsweetened applesauce, though the crumb will be slightly less rich and the browned butter flavor won’t come through as strongly.
For a nut-free version, simply omit the walnuts, the bread holds together the same without them and nothing else in the recipe needs adjusting.
Serving Suggestions
A smear of salted butter on a warm slice is the simplest pairing, letting the bread’s flavor stand on its own. Cream cheese spread over a slice turns this into more of a dessert-leaning snack. A scoop of vanilla ice cream alongside a warm slice works well if you’re serving this as an actual dessert rather than breakfast. For drinks, a cup of coffee or chai pairs naturally with the cinnamon already in the batter.

FAQ
Can I make chocolate chip banana bread ahead of time?
Yes, the baked loaf keeps well wrapped tightly at room temperature for up to 4 days, and the flavor often deepens by the second day. You can also freeze it whole or pre-sliced for up to 3 months, thawing at room temperature when you’re ready to serve.
Why does my banana bread always turn out gummy in the middle?
This almost always means there was too much mashed banana relative to the flour in the batter, since banana size varies enough that counting bananas instead of weighing them throws off the ratio. Weigh the mashed banana to the gram amount called for rather than estimating by banana count.
Can I substitute oil for the browned butter?
You can, using a neutral oil like vegetable or canola in the same amount, though you’ll lose the nutty depth that browning the butter adds. The texture stays similar either way, the difference is mainly in flavor complexity.
How do I know when the bread is fully baked?
Insert a toothpick into the thickest part of the loaf, it should come out with a few moist crumbs clinging to it, not wet batter and not completely dry. This usually happens between 55 and 65 minutes, checking at the 40-minute mark to see if the top needs a foil tent.
Is this recipe safe for someone with a tree nut allergy?
The walnuts are genuinely optional and can be left out entirely without changing anything else about the recipe. As written with walnuts included, it’s not nut-free, but omitting them makes this a safe option for someone avoiding tree nuts specifically.
One Thing Worth Remembering
The banana amount is the one variable in this recipe that varies the most between kitchens, and it’s also the one that decides whether the center bakes through or stays gummy. Weigh it instead of counting bananas, and the rest of the recipe behaves consistently every single time, regardless of whether this week’s bunch happened to be small or unusually large. That one habit matters more to the final texture than any spice, mix-in, or oven adjustment that follows it.
