This moist and flavorful Rhubarb Bread is the perfect mix of sweet and tangy—made with fresh rhubarb and simple pantry staples. A delicious way to use up extra rhubarb!
Preheat oven to 350°F. Grease a 9x5-inch loaf pan.
In a medium bowl, combine flour, baking soda, baking powder, cinnamon, and salt.
In a large bowl, whisk together the egg, oil, ½ cup brown sugar, sugar, sour cream, and vanilla until smooth and well combined.
Add the dry ingredients to the wet ingredients and stir just until combined. Gently fold in the chopped rhubarb.
Spread the batter evenly into the prepared loaf pan. Sprinkle the top with 1 tablespoon of brown sugar.
Bake for 50 minutes, or until a toothpick inserted into the center comes out clean. If the top starts to brown too quickly, loosely tent with foil during the last 15 minutes.
Let the bread cool in the pan for 10 minutes, then transfer to a wire rack to cool completely.
