Ingredients

• 1 1/2 cups all-purpose flour
• 1 teaspoon baking soda
• 1/2 teaspoon ground cinnamon
• 1/4 teaspoon salt
• 1 cup granulated sugar, plus 2 tablespoons for topping
• 1/2 cup unsalted butter, softened (or neutral oil)
• 2 large eggs
• 1 teaspoon vanilla extract
• 1/2 cup buttermilk (or milk mixed with 1/2 tsp lemon juice)
• 1 1/2 cups chopped rhubarb, cut into 1/2-inch pieces
• For the Glaze: 1 cup powdered sugar
• For the Glaze: 2–3 tablespoons milk or lemon juice

Step-by-Step Instructions

1. Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Grease and flour a standard 9×5 inch loaf pan, or line it with parchment paper, leaving an overhang for easy removal.
2. In a medium bowl, whisk together the flour, baking soda, cinnamon, and salt. Set aside.
3. In a large bowl, cream together the 1 cup of granulated sugar and the softened butter (or oil) until light and fluffy. Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract.
4. Alternately add the dry ingredients mixture and the buttermilk to the wet ingredients, beginning and ending with the dry ingredients. Mix only until just combined; do not overmix the batter.
5. Gently fold in the chopped rhubarb until it is evenly distributed throughout the batter.
6. Pour the batter into the prepared loaf pan and smooth the top. Sprinkle the remaining 2 tablespoons of granulated sugar evenly over the top of the batter for a slight crust, if desired.
7. Bake for 50 to 65 minutes, or until a wooden skewer inserted into the center comes out clean or with just a few moist crumbs attached. If the top begins to brown too quickly, loosely tent the pan with aluminum foil for the remaining baking time.
8. Let the bread cool in the pan for 10 minutes before carefully turning it out onto a wire rack to cool completely.
9. While the bread is cooling, prepare the glaze. Whisk together the powdered sugar and 2 tablespoons of milk or lemon juice until smooth. Add the remaining liquid slowly, only if needed, to reach a thick but pourable consistency.
10. Once the bread is completely cool, drizzle the sweet glaze evenly over the top. Allow the glaze to set before slicing and serving your Perfect Rhubarb Bread with Sweet Glaze.

Expert Tips / Pro Tips

• Tossing the Rhubarb: To prevent the rhubarb from sinking to the bottom of the loaf, lightly toss the chopped stalks in one tablespoon of the flour mixture before folding them into the batter.
• Check Oven Accuracy: Quick breads can be sensitive to temperature fluctuations. Use an oven thermometer to ensure your oven is calibrated correctly for even baking.
• Don’t Overmix: Overmixing develops gluten, leading to a dense, tough bread. Mix only until the streaks of flour disappear.
• For a Tangier Glaze: If you prefer a glaze that mirrors the tartness of the interior, substitute the milk in the glaze entirely with fresh lemon juice.

Variations & Substitutions

• Nuts: Fold in 1/2 cup of chopped pecans or walnuts along with the rhubarb for added crunch.
• Spices: Add 1/4 teaspoon of ground nutmeg or cardamom to the flour mixture for added warmth.
• Citrus Zest: Mix the zest of one lemon or orange into the butter and sugar mixture for a bright background flavor.
• Dairy-Free Option: Substitute the buttermilk with plain unsweetened plant-based milk (like soy or almond) mixed with a teaspoon of apple cider vinegar, letting it sit for 5 minutes before using.

Serving Suggestions

This moist bread is fantastic on its own with a hot cup of coffee or tea for breakfast. For a more decadent treat, serve slices slightly warmed with a dollop of fresh whipped cream or lightly sweetened mascarpone cheese. It pairs wonderfully with vanilla bean ice cream for a simple dessert.

Storage, Freezing & Reheating

Storage: Store the cooled, un-glazed bread tightly wrapped in plastic wrap or in an airtight container at room temperature for up to 3 days. If glazed, it can usually last 2 days at room temperature, though refrigeration may be necessary in very warm or humid climates (which can sometimes make the bread slightly denser). For best texture, bring refrigerated bread back to room temperature before eating.

Freezing: This bread freezes beautifully. Wrap the cooled, un-glazed loaf tightly in plastic wrap and then in aluminum foil. Freeze for up to 3 months. To thaw, unwrap and let it sit at room temperature for several hours.

Reheating: If frozen, thaw completely as described above. If reheating a slice that has gone slightly stale, wrap it in a damp paper towel and microwave on 50% power for 15–20 seconds to restore moisture.

FAQ

Can I use frozen rhubarb instead of fresh?

Yes, you can use frozen rhubarb. Do not thaw it first. Toss the frozen rhubarb directly with the flour mixture before folding it into the batter to prevent it from bleeding too much color into the entire loaf, and you may need to add 5–10 minutes to the baking time.

My rhubarb turned everything green! What happened?

Rhubarb contains strong pigments that can bleed during baking, turning parts of the batter slightly pink or greenish, depending on the acidity. This is normal. Tossing the rhubarb in flour (as suggested in the Pro Tips) helps create a barrier and minimize this effect.

How do I know when the bread is perfectly baked?

The most reliable method is the skewer test. A wooden skewer inserted into the thickest part of the center of the loaf should come out clean or with only a few moist crumbs sticking to it. If wet batter slides off, continue baking.

Can I bake this as muffins instead of a loaf?

Certainly! To make muffins, reduce the baking time significantly, usually to about 20–25 minutes at the same temperature (350°F/175°C). Fill the muffin cups about 2/3 full.

Method

 

Instructions

1. Preheat your oven to 350°F (175°C). Grease and flour a standard 9×5 inch loaf pan.
2. In a medium bowl, toss the chopped rhubarb with the reserved 1/4 cup of granulated sugar. Set aside while preparing the batter.

5. Gently fold in the sugared rhubarb pieces, distributing them evenly throughout the batter.
6. Pour the batter into the prepared loaf pan and spread evenly. Bake for 50 to 60 minutes, or until a wooden skewer inserted into the center comes out clean. Let cool in the pan for 15 minutes before turning out onto a wire rack to cool completely.
7. While the bread cools, prepare the glaze: Whisk together the powdered sugar and 2 tablespoons of milk or lemon juice until smooth. Add more liquid, a teaspoon at a time, until you reach a thick but pourable consistency.
8. Once the bread is completely cool, drizzle the sweet glaze evenly over the top. Let the glaze set before slicing and serving.

Notes

For an extra burst of flavor, add 1 teaspoon of lemon zest to the wet ingredients. If rhubarb is unavailable, strawberries or blueberries make excellent substitutions.
