Description

Banana bread is a comfort food classic. My secret is plenty of brown sugar, overripe bananas, and a specific mixing order for the ultimate sourdough banana bread. Recipe adapted from The Boathouse restaurant in Manly, Australia.

Notes: 

Out of sourdough starter? You can still make this recipe (and it’s delicious!). Increase the milk to 125 ml (1/2 cup) total.

You will need a standard 9×5-inch loaf pan or three 7x3x2 mini loaf pans for baking.


Ingredients

Butter, for coating the pan

375 g overripe bananas, weighed with the skin on (about 2 medium bananas)

225 g (1 1/4 cups lightly packed) light or dark brown sugar

1½ tsp pure vanilla extract

2 large eggs

100 g (appx. 1/2 cup) bubbly, active 100% hydration sourdough starter

250g (2 cups) all-purpose flour

1½ tsp baking soda

1/4 tsp fine sea salt

125ml (½ cup) neutral flavored oil

60ml (1/4 cup) milk

Powdered sugar, butter, and mascarpone cheese for serving, optional


Instructions

Preheat the oven to 360 F.

Lightly coat three 7x3x2 mini loaf pans or one 9×5-inch loaf pan with butter.

Add the bananas, sugar, and vanilla to a bowl. Cream with a hand held mixer or stand mixer fitted with the paddle attachment, about 30 seconds to 1 minute (some small lumps of banana are okay).

Add the eggs, one at a time until fully incorporated. Add the sourdough starter.

Sift the flour, baking soda, and salt together in a separate bowl. Working in batches, add this to the banana mixture.

Add the milk and oil and mix until just combined. Do not over do it; the banana bread will be tough.

Pour the batter into the prepared pan(s). If using the mini loaf pans, place them onto a baking sheet and transfer to the oven.

Bake for 45 minutes (for the mini loaf pans) or 60- 65 minutes (for the standard 9×5-inch pan), until rich golden brown and a toothpick comes out clean. Cover with foil if the loaf browns too quickly.

Cool in the pan for 20 minutes, and then transfer to a wire rack to cool completely.

Serve with powdered sugar for a nice touch!
