Ingredients

For the Muffins

• 2 cups all-purpose flour
• 1 teaspoon baking powder
• ½ teaspoon baking soda
• ½ teaspoon salt
• 1 teaspoon ground cinnamon
• ½ cup granulated sugar
• ¼ cup light brown sugar, packed
• 2 large eggs, room temperature
• ½ cup unsalted butter, melted and slightly cooled
• ½ cup sour cream
• 1 teaspoon pure vanilla extract
• 2 cups fresh rhubarb, diced into ½-inch pieces

Optional Streusel Topping

• ¼ cup all-purpose flour
• 2 tablespoons light brown sugar
• 2 tablespoons granulated sugar
• ½ teaspoon ground cinnamon
• 2 tablespoons cold unsalted butter, cubed

Instructions

Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Line a 12-cup muffin pan with paper liners or lightly grease each cup with nonstick cooking spray.

Step 2: Make the Streusel (Optional)

In a small bowl, combine the flour, brown sugar, granulated sugar, and cinnamon.

Cut in the cold butter using a fork or pastry cutter until the mixture resembles coarse crumbs. Refrigerate while preparing the muffin batter.

Step 3: Mix the Dry Ingredients

In a large mixing bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, granulated sugar, and brown sugar until evenly combined.

Step 4: Mix the Wet Ingredients

In a separate bowl, whisk together the eggs, melted butter, sour cream, and vanilla extract until smooth.

Step 5: Combine the Batter

Pour the wet ingredients into the dry ingredients and stir gently until just combined.

Fold in the diced rhubarb using a spatula. Avoid overmixing, as this can make the muffins dense.

Step 6: Fill the Muffin Cups

Divide the batter evenly among the prepared muffin cups, filling each about ¾ full.

Sprinkle the streusel topping evenly over each muffin, if using.

Step 7: Bake

Bake for 22–25 minutes, or until the tops are golden and a toothpick inserted into the center comes out clean or with a few moist crumbs.

Step 8: Cool

Allow the muffins to cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.

Serve warm or at room temperature.

Tips for the Best Rhubarb Muffins

• Use fresh, firm rhubarb for the best flavor and texture.
• Cut the rhubarb into evenly sized pieces so it bakes uniformly.
• Don’t overmix the batter—stir just until the flour disappears.
• Room-temperature eggs and sour cream help create a smooth batter.
• The streusel topping adds a delicious bakery-style crunch.
• If your rhubarb is especially tart, sprinkle it with a tablespoon of sugar before folding it into the batter.
• Let the muffins cool slightly before serving to allow the crumb to set.
• Store leftovers in an airtight container to keep them moist.

Variations

Strawberry Rhubarb Muffins

Replace 1 cup of the rhubarb with chopped fresh strawberries for a classic flavor combination.

Lemon Rhubarb Muffins

Add 1 tablespoon of fresh lemon zest to the batter for a bright citrus twist.

Oat Streusel Muffins

Mix rolled oats into the streusel topping for extra texture and a hearty finish.

Walnut Rhubarb Muffins

Fold ½ cup chopped walnuts or pecans into the batter for added crunch.

Orange Rhubarb Muffins

Add orange zest and a splash of fresh orange juice for a sweet citrus flavor.

Whole Wheat Rhubarb Muffins

Replace half of the all-purpose flour with whole wheat flour for a heartier muffin.

Recipe Notes

• Fresh rhubarb delivers the best flavor, but frozen rhubarb can also be used. Thaw and drain it well before adding it to the batter.
• Sour cream helps create an exceptionally moist and tender crumb.
