The Secret to Flavorful Banana Bread

The best banana bread begins with very ripe bananas. Bananas covered in brown spots—or even bananas that have turned nearly black—are ideal because they are softer, sweeter, and more flavorful.

If your bananas ripen before you are ready to bake, peel them and store them in a freezer-safe bag. Allow frozen bananas to thaw before using them, and include the liquid they release when mashing them.

How to Create the Cinnamon Swirl

Creating the swirl is much easier than it looks. Pour half of the banana-bread batter into the prepared loaf pan and sprinkle half of the cinnamon-sugar mixture over it. Add the remaining batter, followed by the rest of the cinnamon sugar.

Run a butter knife or skewer gently through the batter in a loose swirling motion. A few passes are plenty. Swirling too much can blend the cinnamon mixture completely into the batter instead of leaving those pretty ribbons inside the bread.

Tips for the Best Banana Bread

Avoid overmixing

Stir the flour into the wet ingredients only until everything is combined. Overmixing develops too much gluten and can make the bread dense or tough.

Check the loaf near the end

Ovens can vary, so begin checking the bread after about 55 minutes. Insert a toothpick into the center. It should come out clean or with only a few moist crumbs attached.

Protect the top if needed

If the top begins getting too dark before the center is fully baked, loosely cover the loaf with aluminum foil for the remainder of the baking time.

Let it cool

It is tempting to slice into the loaf immediately, but allowing it to cool helps the bread set and makes it easier to cut into clean slices.

How to Store Cinnamon Swirl Banana Bread

Store the cooled bread in an airtight container at room temperature for up to three days. For longer storage, refrigerate it for up to one week.

You can also freeze the bread. Wrap individual slices securely and place them in a freezer-safe container for up to three months. Thaw a slice at room temperature or warm it briefly in the microwave whenever you need a cozy little treat.
