FAQs

How ripe should the bananas be for this recipe?

Very ripe bananas with lots of brown spots work best—they’re sweeter and mash more easily, adding both flavor and moisture.

Can I make these bars without sugar?

Yes, you can omit the brown sugar if your bananas are very sweet, or use a natural sweetener like maple syrup or honey instead.

Are these bars gluten-free?

They can be, as long as you use certified gluten-free rolled oats.

Can I use quick oats instead of rolled oats?

Yes, but the texture will be slightly softer and less chewy. Rolled oats give the bars a heartier consistency.

How do I make these bars vegan?

Simply swap the milk for a plant-based alternative and make sure your chocolate chips are dairy-free.

Can I double the recipe?

Absolutely. Just use a larger baking dish and adjust the baking time slightly—start checking around 35 minutes.

Can I use a different oil instead of coconut oil?

Yes, melted butter, vegetable oil, or any neutral oil will work well in place of coconut oil.

What’s the best way to mash bananas?

A fork works just fine, but for a super smooth mash, use a potato masher or even a hand blender.

Do I need to let them cool before cutting?

Yes, letting them cool helps the bars firm up and makes them easier to cut without falling apart.

Can these be eaten cold?

Definitely. They taste great straight from the fridge, especially with a little nut butter spread on top.
