Moist, tender, and swirled with cinnamon sugar, this is one of the easiest sourdough quick bread recipes you’ll bake. A cozy way to use up sourdough discard and create something special without the wait.
Preheat oven to 350°F. Line a loaf pan with parchment.
In a large bowl, whisk flour, baking soda, salt, and granulated sugar. Set aside.
Whisk discard, eggs, oil, vanilla, milk and sour cream in a large mixing bowl.
Pour wet ingredients into dry ingredients and mix until just combined. If it feels too thick, add another splash of milk until it loosens up.
Now it’s time to layer. Spread a third of the batter in the pan, sprinkle on half the cinnamon sugar, add another third of the batter, then the rest of the cinnamon sugar, and finally the last bit of batter. Grab a butter knife and give it a gentle swirl through the loaf to make those pretty ribbons.
Bake 50–60 minutes, until golden brown and a toothpick comes out clean.
Cool in pan for 10 minutes, then transfer to rack. Slice and enjoy.
