Ingredients

2 cups (280 g) all purpose gluten free flour blend (See Recipe Notes for Recommendations)
1 teaspoon xanthan gum omit if your blend already contains it
¾ teaspoon kosher salt
1 teaspoon baking powder
½ teaspoon baking soda
⅔ cup (133 g) granulated sugar
8 tablespoons (112 g) unsalted butter melted and cooled
2 (100 g weighed out of shell) eggs at room temperature, beaten
1 teaspoon pure vanilla extract
⅔ cup (150 g) sour cream at room temperature (avoid fat-free)
200 grams (2 medium-size bananas) peeled ripe bananas the weight measurement is especially important here
1 small slightly less ripe banana sliced thinly lengthwise, for topping (optional)

Instructions

Preheat your oven to 350°F. Grease a standard 9 x 5 inch loaf pan, and set it aside.
In a large bowl, place the all purpose gluten free flour, xanthan gum, salt, baking powder, baking soda and sugar. Whisk to combine well.
Create a well in the center of the dry ingredients. Add the melted butter, eggs, and vanilla, then the sour cream. Mix until just combined.
If your bananas are very ripe and soft, mash them gently with a large fork, maintaining as much texture as possible. If your bananas are less ripe but still fragrant, mash with a fork until the mixture has texture but also some smoothness.
Use a silicone spatula to fold the mashed bananas gently into the batter to avoid processing the bananas even further.
Scrape the batter into the prepared loaf pan, and smooth the top with a spatula dipped in water. If you're using the optional banana as a topping, place very thinly sliced bananas (cut lengthwise) on top of the smooth batter, sparingly.
Place the pan in the center of the preheated oven. Bake until the top is golden brown and a toothpick inserted in the center comes out with a few moist crumbs but no wet batter.
Baking time will be about 50 minutes without the additional bananas on top, and about 1 hour with them. If the top is browning too quickly before the center is fully set, tent loosely with foil for the final 10–15 minutes.
Let the banana bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.

Notes

Flour blend recommendations

I suggest using Better Batter's original blend gluten free flour without added xanthan gum, Nicole's Best multipurpose blend with xanthan gum, or Bob's Red Mill 1-to-1 Gluten Free Baking Flour with an additional ½ teaspoon xanthan gum to avoid crumbly bread.

For full details including how to make your own "mock" Better Batter or original Cup4Cup, see my gluten free flour blends guide.
