Rhubarb muffins are the perfect way to enjoy the tartness of rhubarb in a soft, moist, and slightly sweet baked treat.
Whether you pick fresh rhubarb from your garden or buy stalks at the local market, these muffins are a delicious way to showcase this unique vegetable in the world of baking. Ideal for breakfast, brunch, or a snack on the go, rhubarb muffins are easy to make and offer a wonderful balance of texture and flavor that’s hard to resist.
What Makes Rhubarb Muffins Special?
Rhubarb muffins stand out because of their delicate balance of sweet and tart. Unlike blueberries or chocolate chips, which add pure sweetness to muffins, rhubarb brings a tangy kick that keeps every bite interesting. The muffins are tender and fluffy inside with small bursts of sourness from rhubarb pieces, complemented by just the right amount of sugar or other sweeteners. You can dress them up with streusel topping, cinnamon, or even nuts to add texture and extra flavor.
The Best Type of Rhubarb for Muffins
For baking, fresh rhubarb is always preferred. Look for firm, crisp stalks with a rich red or pink hue; these typically have a sweeter taste and stronger flavor. Greenish stalks are perfectly fine to use but may be slightly more tart. If fresh rhubarb is out of season, frozen rhubarb works as a great substitute—just be sure to thaw and drain it well to avoid excess moisture that can make the muffins soggy.
Ingredients You’ll Need for Classic Rhubarb Muffins
To make a batch of 12 fluffy rhubarb muffins, you’ll need the following ingredients:
- 2 cups all-purpose flour
- 1 cup granulated sugar
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1 teaspoon ground cinnamon (optional, for warmth)
- 1/2 cup vegetable oil or melted butter
- 1/2 cup buttermilk or plain yogurt
- 1 large egg
- 1 1/2 teaspoons vanilla extract
- 1 1/2 cups diced rhubarb (fresh or frozen, drained if frozen)
- Optional: 1/4 cup chopped walnuts or pecans for crunch
- Optional: Coarse sugar for sprinkling on top
Step-by-Step Recipe: How to Make Rhubarb Muffins
Step 1: Preheat the Oven and Prepare the Pan Preheat your oven to 375°F (190°C) and line a 12-cup muffin tin with paper liners or grease lightly with cooking spray.
Step 2: Mix Dry Ingredients In a large mixing bowl, whisk together the flour, sugar, baking powder, baking soda, salt, and cinnamon until well combined.
Step 3: Mix Wet Ingredients In a separate bowl, whisk the oil (or melted butter), buttermilk, egg, and vanilla extract until smooth.
Step 4: Combine Wet and Dry Ingredients Pour the wet mixture into the dry ingredients and gently stir until just combined. Be careful not to overmix; the batter should be lumpy but no dry streaks of flour should remain.
Step 5: Fold in Rhubarb Gently fold the diced rhubarb and nuts (if using) into the batter. The rhubarb should be evenly distributed throughout without overworking the batter.
Step 6: Fill Muffin Cups Divide the batter evenly among the 12 muffin cups, filling each about 3/4 full. Sprinkle the tops with coarse sugar for a crunchy finish if desired.
Step 7: Bake and Cool Bake for 18–22 minutes or until a toothpick inserted in the center of a muffin comes out clean. Allow the muffins to cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
Tips for Perfect Rhubarb Muffins
Don’t Overmix Overmixing the batter will make the muffins tough rather than soft and tender. Stir until the dry ingredients are just moistened.
Use Buttermilk or Yogurt The acidity in buttermilk or yogurt reacts with the baking soda to create extra fluffy and moist muffins. If you don’t have buttermilk, you can make a quick substitute by adding 1 tablespoon of lemon juice or vinegar to 1/2 cup of milk.
Cut Rhubarb Evenly Small, even pieces of rhubarb ensure every muffin bite gets a balanced taste and texture without overwhelming chunks.
Sprinkle Sugar on Top A little coarse or turbinado sugar sprinkled on top before baking gives the muffins a satisfying crunchy top.
Try Add-Ins Chopped nuts, white chocolate chips, or even shredded coconut can add flavor and texture to your muffins without overpowering the rhubarb.
Variations of Rhubarb Muffins
Strawberry Rhubarb Muffins Add 1 cup of diced strawberries along with rhubarb for a classic flavor pairing that brings extra sweetness and moisture to the muffins.
Lemon Rhubarb Muffins Add 1 tablespoon of fresh lemon zest to the batter for a citrusy kick that brightens the rhubarb’s tartness.
Cinnamon Streusel Rhubarb Muffins Top the muffin batter with a mixture of brown sugar, cinnamon, and butter before baking to create a crunchy, flavorful streusel topping.
Whole Wheat Rhubarb Muffins Replace half the all-purpose flour with whole wheat flour for a slightly denser, nuttier muffin with added fiber.
Vegan Rhubarb Muffins Use a flaxseed egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water) and non-dairy yogurt or milk to make a plant-based version without sacrificing flavor or texture.
Health Benefits of Rhubarb Muffins
Though considered a treat, rhubarb muffins offer some surprising nutritional benefits thanks to their main ingredient. Rhubarb is rich in dietary fiber, aiding digestion and promoting gut health. It also contains antioxidants such as anthocyanins and polyphenols, which can help fight inflammation. With the addition of buttermilk or yogurt, these muffins provide a small boost of calcium and probiotics. If you use whole wheat flour or add nuts, you can increase the fiber and healthy fat content even more.
How to Store and Freeze Rhubarb Muffins
Storing Rhubarb Muffins Freshly baked rhubarb muffins will stay moist and delicious for 2 to 3 days if kept in an airtight container at room temperature. To keep them fresh longer, store them in the refrigerator for up to a week.
Freezing Rhubarb Muffins These muffins freeze beautifully. Once cooled, place them in a single layer on a baking sheet and freeze for 1 hour. Then transfer them to a freezer-safe zip-top bag or container. They will keep well in the freezer for up to 3 months. To enjoy, simply thaw at room temperature or warm briefly in the microwave or oven.
