Full Ingredients

For the Rhubarb

• 1 1/2 cups chopped rhubarb, cut into 1/4-inch pieces, from about 6 to 8 ounces fresh rhubarb stalks
• 1 tablespoon all-purpose flour, for tossing with the rhubarb

For the Muffin Batter

• 2 cups all-purpose flour, spooned and leveled
• 3/4 cup granulated sugar
• 2 teaspoons baking powder
• 1/4 teaspoon baking soda
• 1 teaspoon ground cinnamon
• 1/2 teaspoon fine salt
• 1/2 cup unsalted butter, melted and cooled for 5 minutes

• 3/4 cup buttermilk, room temperature
• 2 teaspoons vanilla extract

For the Cinnamon Sugar Top

• 2 tablespoons turbinado sugar or coarse sugar
• 1/4 teaspoon ground cinnamon

Step-by-Step Instructions

Step 1: Heat the oven and prepare the pan

Preheat the oven to 425°F. Line a standard 12-cup muffin pan with paper liners, or grease the cups well with butter or nonstick spray. Set the pan near your work area so you can fill it as soon as the batter is mixed.

Step 2: Chop and coat the rhubarb

Trim the rhubarb stalks and discard any leaves, as rhubarb leaves are not edible. Chop the stalks into small 1/4-inch pieces. Place the chopped rhubarb in a small bowl and toss it with 1 tablespoon all-purpose flour. This light flour coating helps the rhubarb stay evenly distributed in the muffins instead of sinking to the bottom.

Step 3: Mix the dry ingredients

In a large mixing bowl, whisk together 2 cups all-purpose flour, 3/4 cup granulated sugar, 2 teaspoons baking powder, 1/4 teaspoon baking soda, 1 teaspoon ground cinnamon, and 1/2 teaspoon fine salt. Whisk for about 30 seconds so the leaveners and cinnamon are evenly spread through the flour.

Step 4: Mix the wet ingredients

In a medium bowl, whisk together the 1/2 cup melted and cooled unsalted butter, 2 large eggs, 3/4 cup buttermilk, and 2 teaspoons vanilla extract until smooth and well combined. The butter should be melted but not hot; if it is too warm, it may scramble the eggs or make the batter greasy.

Step 5: Combine the batter gently

Pour the wet ingredients into the bowl of dry ingredients. Use a spatula to fold the mixture together just until the flour is mostly moistened. A few small streaks of flour are fine at this stage. Add the floured rhubarb and fold gently until evenly distributed. Do not overmix; the batter should look thick, soft, and slightly lumpy.

Step 6: Fill the muffin cups and add the topping

In a small bowl, stir together 2 tablespoons turbinado sugar and 1/4 teaspoon ground cinnamon. Divide the batter evenly among the 12 prepared muffin cups, using about 1/4 cup batter per muffin. The cups should be about three-quarters full. Sprinkle the cinnamon sugar evenly over the tops, using about 1/2 teaspoon topping per muffin.

Step 7: Bake for tall, golden muffins

Place the muffin pan in the oven and bake at 425°F for 5 minutes. Without opening the oven door, reduce the oven temperature to 375°F and continue baking for 15 minutes, for a total bake time of 20 minutes. The muffins are done when the tops are golden, the centers spring back lightly when touched, and a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs.

Step 8: Cool before serving

Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack and cool for at least 10 minutes more. This short cooling time helps the crumb set while keeping the muffins tender and warm. Serve as they are, or with softened butter for an extra homey touch.

Pro Tips

• Keep the rhubarb pieces small: Pieces around 1/4 inch soften nicely in the 20-minute bake time and give you tart little pockets without making the muffins soggy.
• Use room-temperature dairy and eggs: Room-temperature eggs and buttermilk blend more smoothly with the melted butter, giving the muffins a more even, tender crumb.
• Do not overmix: Stir only until the batter comes together. Overmixing can make muffins dense or rubbery instead of soft and fluffy.
• Color does not equal flavor: Green rhubarb can be just as delicious as pink or red rhubarb. Red rhubarb gives the prettiest rosy flecks, but all colors work.
• If using frozen rhubarb: Use it straight from the freezer without thawing, toss it with the flour as directed, and bake the 375°F portion for 16 minutes instead of 15 minutes.

Variations

• Orange Vanilla Rhubarb Muffins: Add 1 tablespoon finely grated orange zest to the sugar and dry ingredients. The citrus makes the rhubarb taste especially bright.
• Strawberry Rhubarb Muffins: Use 1 cup chopped rhubarb and 1/2 cup finely diced strawberries. Toss both fruits with the 1 tablespoon flour before folding them into the batter.
• Nutty Cinnamon Rhubarb Muffins: Fold 1/3 cup chopped walnuts or pecans into the batter with the rhubarb for a cozy, rustic crunch.

Storage & Make-Ahead

Store cooled muffins in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate them for up to 5 days, though the texture is best when they are gently rewarmed. To reheat, place muffins in a 300°F oven for 8 minutes, or microwave one muffin for 15 seconds. To freeze, wrap cooled muffins individually and freeze in a freezer-safe bag for up to 3 months. Thaw at room temperature for about 1 hour or rewarm from frozen in a 300°F oven for 15 minutes. For make-ahead prep, chop the rhubarb up to 1 day in advance and refrigerate it in a covered container; mix the batter only right before baking for the best rise.
