There’s something uniquely satisfying about the bright tang of rhubarb tucked into a warm, fluffy muffin—especially when topped with a crackly layer of cinnamon sugar. Rhubarb Muffins with Cinnamon Sugar Topping bring together sweet, tart, and spicy flavors in a moist, tender package that’s perfect for breakfast, brunch, or an afternoon treat.
This recipe celebrates the rustic charm of home baking with a delightful balance of flavors and a nostalgic appeal. Whether you grow rhubarb in your backyard or pick it up at the farmers’ market, these muffins are a perfect way to make use of the seasonal favorite.
Why Rhubarb Deserves the Spotlight
Often overlooked in favor of fruits like strawberries or blueberries, rhubarb is a garden gem that brings a distinctive tartness to baked goods. Technically a vegetable, rhubarb behaves like a fruit in desserts—especially when sweetened and baked into soft, golden muffins.
It’s not only flavorful but also rich in fiber, antioxidants, and vitamin K. In this recipe, rhubarb’s natural acidity is balanced beautifully by the sweetness of the batter and the warmth of a cinnamon sugar topping.
What Makes These Muffins Special?
These muffins are simple to prepare but deliver complex flavor and texture. Here’s what sets them apart:
- Tangy Rhubarb: Chopped rhubarb adds bursts of tartness throughout the muffin.
- Tender Crumb: Buttermilk or sour cream makes the crumb moist and soft.
- Cinnamon Sugar Topping: A crunchy topping adds a sweet-spicy contrast and lovely texture.
- Versatile Base: The muffin batter can be adapted with other fruits, nuts, or spices.
Ingredients
For the Muffins:
- 2 cups all-purpose flour
- ¾ cup granulated sugar
- 2 teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 teaspoon ground cinnamon
- 1 cup buttermilk or sour cream
- ½ cup vegetable oil or melted butter
- 1 teaspoon vanilla extract
- 1 large egg
- 1 ½ cups fresh rhubarb, chopped (about ½-inch pieces)
For the Cinnamon Sugar Topping:
- 2 tablespoons granulated sugar
- 1 teaspoon ground cinnamon
- Optional: 1 tablespoon melted butter for brushing muffin tops
Instructions
1. Preheat and Prep
Preheat your oven to 375°F (190°C). Line a 12-cup muffin tin with paper liners or grease lightly with cooking spray.
2. Mix Dry Ingredients
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt, and cinnamon.
3. Combine Wet Ingredients
In another bowl, whisk the buttermilk, oil (or butter), egg, and vanilla until well blended.
4. Bring It Together
Add the wet mixture to the dry ingredients and stir just until combined—do not overmix. Gently fold in the rhubarb.
5. Fill Muffin Cups
Spoon the batter evenly into the muffin cups, filling each about ¾ full.
6. Add Cinnamon Sugar Topping
In a small bowl, mix the sugar and cinnamon. Sprinkle generously over each muffin. If desired, brush muffin tops lightly with melted butter before adding the topping for extra richness.
7. Bake
Bake for 18–22 minutes, or until a toothpick inserted into the center comes out clean and the tops are golden brown.
8. Cool and Serve
Let muffins cool in the pan for 5 minutes before transferring them to a wire rack. Serve warm or at room temperature.
