- 2 large eggs, at room temperature
- 1 3/4 cups all-purpose flour
- 1 1/2 tsp. baking powder

How To Make Rhubarb Bread
- Prep Oven and Make Streusel: Preheat the oven to 350°F. Spray an 8.5×4.5-inch loaf pan with baking spray and line it with a parchment paper sling. In a medium bowl, whisk together the flour, sugar, and oats for the streusel. Use your fingers to rub the cold butter into the flour mixture until it clumps together. Cover and refrigerate.
- Mix the Bread Batter: In a large bowl, whisk together the granulated sugar, sour cream, oil, orange zest, vanilla, and eggs. In a separate medium bowl, whisk together the flour, baking powder, baking soda, cardamom, and salt.
- Combine and Bake: Add the dry ingredients to the wet ingredients in two parts, whisking after each addition until just combined. Gently fold in the chopped rhubarb.
- Assemble and Bake: Spoon the batter into the prepared loaf pan. Break the cold streusel into small pieces and sprinkle it evenly over the top. Bake for 1 hour and 5 minutes to 1 hour and 15 minutes, until a toothpick inserted in the center comes out clean.
- Cool Completely: Let the bread cool in the pan for 10 minutes before using the parchment sling to lift it out onto a wire rack to cool completely, for at least 1 hour.
- Make the Brown-Butter Glaze: Once the loaf has cooled, make the glaze. In a small saucepan over medium heat, melt the butter. Continue to cook, swirling, for 6–8 minutes, until it is golden brown and smells nutty. Pour the hot brown butter into a bowl with the sifted powdered sugar, vanilla, and 1 tablespoon of half-and-half. Whisk vigorously until smooth, adding more half-and-half if needed to reach a thick but pourable consistency.
- Glaze and Serve: Drizzle the warm glaze over the completely cooled loaf and let it set for about 15 minutes before serving.

Recipe Tips
- How to get a perfect streusel topping? The secret is to use very cold butter, straight from the fridge, and to chill the finished streusel mixture while you prepare the batter. This helps it bake up crisp and crumbly, rather than melting into a paste.
- How do you get a super moist bread? The combination of oil and sour cream is the key to an incredibly moist and tender quick bread that stays fresh for days. Also, be careful not to overbake it.
- Can I use frozen rhubarb? Yes. If you use frozen rhubarb, it is very important to thaw it completely and then drain off as much excess liquid as possible. Pat it dry with paper towels before adding it to the batter to prevent the bread from being too watery.
- How do I get a nutty, rich glaze? The secret is browning the butter. By cooking the butter until the milk solids toast and turn a golden brown, you create a deep, nutty, and incredibly aromatic flavor that elevates a simple powdered sugar glaze.
What To Serve With Rhubarb Bread
This is a classic quick bread that is delicious on its own, especially for breakfast or as an afternoon snack. It is also wonderful served:
- With a thick smear of salted butter
- With a dollop of cream cheese
- Alongside a hot cup of coffee or tea

How To Store Rhubarb Bread
- Room Temperature: Store the completely cooled and glazed loaf, well-wrapped in plastic wrap or foil, at room temperature. It will stay fresh and moist for up to 4 days.
- Freeze: This bread freezes exceptionally well. Let the loaf cool completely (it’s best to freeze it before adding the glaze). Wrap it tightly in plastic wrap and a layer of foil. It will keep for up to 3 months. Thaw at room temperature before glazing and slicing.

FAQs
Botanically, rhubarb is a vegetable, but it is most often used in a culinary sense like a fruit, especially in sweet dishes like pies and breads, due to its intensely tart flavor that pairs beautifully with sugar.
A sunken center in a quick bread is usually a sign that it was under-baked. Ovens can vary, so always rely on the toothpick test. A toothpick inserted into the very center of the loaf should come out clean, with no wet batter attached.
Yes, 1/2 cup of chopped walnuts or pecans would be a fantastic addition to the streusel topping for extra crunch.

kcalA wonderfully moist and spiced quick bread packed with tart pieces of fresh rhubarb, all finished with a crunchy oat streusel and a rich, nutty brown-butter glaze.
Ingredients
Streusel: 1/2 cup flour, 1/4 cup sugar, 3 Tbsp. oats, 4 Tbsp. cold butter.
Bread: 1 3/4 cups flour, 1 1/2 tsp. baking powder, 1/2 tsp. baking soda, spices (cardamom, salt), 1 cup sugar, 1/2 cup sour cream, 1/2 cup oil, 2 eggs, 1 1/2 cups chopped rhubarb.
Glaze: 1/2 cup powdered sugar, 1 Tbsp. butter (browned), 1-2 tsp milk.
Directions
- Preheat oven to 350°F. Make the streusel by cutting the cold butter into the dry ingredients until crumbly; chill.
- Make the bread batter by combining the wet and dry ingredients separately, then folding them together with the rhubarb.
- Pour the batter into a prepared loaf pan and sprinkle with the chilled streusel.
- Bake for 65-75 minutes, until a toothpick comes out clean. Cool completely.
- Make the glaze by browning the butter and whisking it into the powdered sugar and milk.
- Drizzle the warm glaze over the completely cooled loaf.
Notes
- The most important tip for this recipe is to not overmix the batter; this is the secret to a tender, not tough, quick bread.
- You must let the loaf cool completely before adding the glaze, otherwise the glaze will melt and become transparent.
- For the best flavor, don’t skip the step of browning the butter for the glaze; it adds an incredible nutty depth.
- Using a parchment paper “sling” in your loaf pan is a great trick for easily lifting the finished bread out without breaking it.
