First off: Does banana flour taste like bananas? In short, the answer is no. Since banana flour is made from green bananas, the taste of sweet ripe bananas doesn’t come through. It may add a slight sweetness, but it likely won’t be too noticeable.
It’s also fairly seamless to substitute banana flour for AP flour. “It’s very versatile and can be used in all different recipes, not just baking,” Gawthorne says. For a simple swap, she suggests using the ration of 1 cup AP flour to ¾ cup banana flour. This is due to the higher starch content. “And if you need to make it rise, add 2 teaspoons of baking powder to 1 cup of the banana flour.” TBH, it sounds like classic banana bread is about to get way better.
“Besides baking, you can use banana flour as a thickening agent in soups, stews, and even smoothies,” says Syn. To do so, start with 1 tablespoon and gradually build from there.
One thing to keep in mind when cooking with banana flour is, due to the high starch content, it absorbs more liquid than other flours. So, if you’re looking for something to be light, airy, and fluffy, you’ll want to choose another option for optimal results.
