Chocolate Chip Banana Bread Bars (moist, rich, and naturally sweetened)
if you love chocolate chip cookies and banana bread, these bars are the answer to wanting both at once. they're gluten free and refined sugar free, but you'd never guess from the taste. they come out moist with that soft banana bread crumb and pockets of melted chocolate running through every bite, closer to a brownie in density than an actual loaf of bread.
this is one of my favourite bakes i've developed, and it started because i had a few overripe bananas on the counter and didn't want to make the same loaf again. the riper the bananas, the sweeter the bars end up and the more that classic banana bread flavour comes through. go for the ones that are heavily spotted or almost black, the pale yellow ones won't give you the same result.
i use olive oil instead of butter here, and if you've never baked with it before, trust me on this one. it keeps the bars moist for longer than butter would and adds a depth of flavour you can't quite place, without tasting like olive oil once it's baked. it's also what keeps these dairy free, and it comes with real nutritional upside too, olive oil is rich in polyphenols and monounsaturated fats, both linked to anti-inflammatory and heart health benefits that butter just doesn't offer.
as someone who pretty much only develops gluten free bakes without using a 1:1 gluten free flour blend, i know there's usually a massive texture trade off when you use a gluten free flour from a single source, just almond flour, or just oat flour, or just rice flour! what makes these chocolate chip banana bread bars so good is that the texture is perfection, and that comes down to using both oat flour and almond flour in the right ratios. there's also a real nutritional benefit to combining both flours, they complement each other in fibre, blood sugar support, and they're both nutrient dense on their own!
coconut sugar is the ideal sweetener for this recipe. it works so well with the banana and chocolate combination, providing just the right touch of sweetness and a caramel depth that deepens the flavours. it also has a lower glycemic index than regular white sugar, so the sweetness feels a bit steadier rather than a straight hit.
for the chocolate, i just use chips and chunks, whatever i have in the cupboard, dark or semi-sweet both work. measure them with your heart is not just something to say, i eyeball it every time depending on how chocolatey i'm feeling that day. more on top before baking means more gooey melted pockets once they're out of the oven.
let these cool completely in the tin before you slice them. i know the smell makes that hard, but they firm up as they cool, and slicing them warm just gets you a crumbly mess instead of clean squares.
they keep well too. room temperature in an airtight container for a couple of days, up to 4 days in the fridge, or slice and freeze for up to two months. pull one out whenever ur craving hits and just let it thaw at room temperature or in the oven at a very low temp until warm, for that freshly baked banana bread vibe!
if you're after another gluten free bake that leans indulgent, my brownie cookies or white chocolate brownies are both worth trying next.
Frequently Asked Questions
How do I store chocolate chip banana bread bars?
Store in an airtight container at room temperature for up to 2 days or in the refrigerator for up to 5 days. Allow them to come to room temperature before serving for the best soft texture. You can also warm them briefly in the microwave for 15 to 20 seconds to revive that fresh-from-the-oven feel.
Can I freeze banana bread bars?
Yes, these freeze very well. Slice them first, then store in an airtight freezer-safe container or individual zip-lock bags for up to 2 months. Defrost at room temperature for about 30 minutes or warm slightly in the microwave. They come out tasting just as good as fresh.
Are these chocolate chip banana bread bars gluten free?
Yes, these bars are gluten free as long as you use certified gluten-free oat flour and make sure your chocolate chips are also certified gluten free. Oat flour can be processed in facilities that also handle wheat, so check the label if you have coeliac disease or a serious gluten sensitivity.
Can I substitute the olive oil in banana bread bars?
Yes. Melted coconut oil is the easiest substitute and gives a slightly different but still delicious result. Avocado oil or another neutral-tasting oil also works well. Melted butter can be used if dairy is not a concern, though the bars won't be dairy free. Each oil will slightly change the flavour profile, but olive oil gives the best overall result.
What type of chocolate chips should I use?
Dark chocolate chips pair especially well with the banana and coconut sugar. Semi-sweet chocolate chips also work beautifully. If you need the bars to be fully refined sugar free, look for refined sugar free or coconut sugar sweetened chocolate chips. For an extra indulgent result, use a mix of chocolate chips and chunks so you get some that fully melt and some that hold their shape.
Can I use coconut sugar or do I need a different sweetener?
Coconut sugar is ideal here because its caramel-like flavour pairs so well with banana bread. Brown sugar can be used as a direct substitute if you're not concerned about refined sugar. Maple syrup or honey can work but will add more moisture to the batter, which may require a small reduction in another liquid ingredient or a slightly longer bake time.
Why are my banana bread bars too dense?
Dense bars usually come from over-measuring the flour (especially if using cups rather than a scale), over-mixing the batter once the flour is added, or using bananas that weren't ripe enough. Make sure to fold the dry ingredients until just combined, use a kitchen scale for accuracy, and choose overripe bananas for the best rise and texture.
Pro Tips
- The more overripe the bananas, the sweeter and more flavourful the bars will be. Heavily spotted or blackened bananas are ideal.
- Fold the dry ingredients in gently until just combined. Over-mixing develops too much gluten in the oat flour and can make the bars dense rather than tender.
- Top with extra chocolate chunks on the surface before baking. As they melt they create beautiful gooey pockets throughout the top of every bar.
- Let the bars cool fully before slicing for the cleanest cuts. They continue to set as they cool and are much easier to slice once completely cooled.
