I didn’t grow up eating rhubarb. It wasn’t something my mom kept in the fridge, and honestly, I thought it was some weird vegetable people used in savory dishes. Turns out, rhubarb is actually perfect for baking—it’s tart, a little tangy, and when you mix it with brown sugar and cinnamon, it tastes like spring in muffin form.
These rhubarb muffins are the kind of thing you can throw together on a Saturday morning without much fuss. The cinnamon sugar topping gives them that bakery-style finish, but they’re way easier than anything you’d find at a fancy café. Plus, if you’ve got rhubarb growing in your yard (or know someone who does), this is a great way to use it up before it takes over your garden.
Why You’ll Love These Rhubarb Muffins
- Quick and easy – These muffins come together in under an hour, making them perfect for weekend breakfast or a last-minute brunch contribution.
- Sweet and tangy flavor – The tart rhubarb pairs beautifully with the sweet cinnamon sugar topping, creating a balanced taste that’s not too sugary.
- Simple pantry ingredients – You probably have most of these staples in your kitchen already, so you won’t need a special shopping trip.
- Great for using up rhubarb – If you have rhubarb growing in your garden or find it at the farmers market, this is a delicious way to put it to use beyond the usual pie.
- Freezer-friendly – Make a double batch and freeze extras for busy mornings when you need a grab-and-go breakfast.
What Kind of Rhubarb Should I Use?
Fresh rhubarb is your best bet for these muffins, and you’ll want to look for stalks that are firm and crisp, not limp or bendy. The color can range from light pink to deep red, and while the red stalks look prettier, the greener ones are just as tasty and work perfectly fine in baked goods. Before using your rhubarb, trim off any leaves (they’re actually toxic) and the dry ends, then chop the stalks into small pieces about half an inch in size so they distribute evenly throughout the muffins. If fresh rhubarb isn’t available, frozen rhubarb will work too – just don’t thaw it before adding it to your batter, or you’ll end up with too much extra moisture.
Options for Substitutions
These muffins are pretty forgiving when it comes to swapping ingredients:
- Buttermilk: No buttermilk? Mix 1 cup of regular milk with 1 tablespoon of lemon juice or white vinegar, let it sit for 5 minutes, and you’re good to go. You can also use plain yogurt thinned with a bit of milk.
- Rhubarb: Fresh rhubarb is best, but frozen works too – just thaw it and drain off excess liquid before adding to the batter. You can also swap half the rhubarb with diced strawberries for a classic combo.
- Vegetable oil: Canola oil, melted coconut oil, or melted butter all work well here. If using butter, let it cool slightly before mixing with the wet ingredients.
- Walnuts: Feel free to use pecans instead, or leave them out completely if you’re not a nut person or have allergies.
- Brown sugar: White sugar works in place of brown sugar, though you’ll lose a bit of that molasses flavor. Or mix 1 cup white sugar with 1 tablespoon of molasses.
- Vanilla essence: Vanilla extract is interchangeable with vanilla essence – use the same amount either way.
Watch Out for These Mistakes While Baking
The biggest mistake when baking with rhubarb is not cutting it into small enough pieces – aim for 1/2-inch chunks so they distribute evenly and don’t create pockets of moisture that make your muffins gummy.
Overmixing the batter once you add the dry ingredients to the wet will develop too much gluten and result in tough, dense muffins instead of light and tender ones, so stir just until the flour disappears.
Since rhubarb releases quite a bit of liquid while baking, toss the chopped pieces with a tablespoon of flour before folding them into the batter to help absorb excess moisture.
Finally, don’t skip greasing those muffin pans well – the sugar topping can make these muffins stick like crazy, so use plenty of butter or cooking spray to ensure they pop out cleanly.
What to Serve With Rhubarb Muffins?
These rhubarb muffins are perfect for breakfast or brunch alongside a hot cup of coffee or tea. I love serving them with a pat of butter that melts right into the warm muffin, or you can spread on some cream cheese for extra richness. They also make a great afternoon snack with a glass of cold milk, and the cinnamon sugar topping means they’re sweet enough to enjoy on their own without anything extra. If you’re putting together a brunch spread, set these out with fresh fruit, scrambled eggs, and maybe some yogurt for a complete meal.
Storage Instructions
Store: Keep your rhubarb muffins in an airtight container at room temperature for up to 3 days, or in the fridge for about a week. The cinnamon sugar topping might soften a bit over time, but they’ll still taste great with your morning coffee.
Freeze: These muffins freeze really well for up to 3 months. Just wrap them individually in plastic wrap, then place them in a freezer bag. This way you can grab one or two whenever you want a quick breakfast or snack.
Thaw: Let frozen muffins sit at room temperature for about an hour, or warm them in the microwave for 20-30 seconds. You can also pop them in a 300°F oven for about 10 minutes if you want that fresh-baked feel again.

Ingredients
For the muffins:
- 3 1/4 cups flour (I always use King Arthur all-purpose flour)
- 1 tsp baking soda
- 1 1/4 tsp baking powder
- 1/2 tsp salt
- 1 cup brown sugar (packed firmly for a deeper molasses flavor)
- 1 cup buttermilk
- 1/2 cup vegetable oil
- 1 egg (room temperature, about 70°F)
- 1 1/2 tsp vanilla
- 2 cups rhubarb (chopped into 1/2-inch pieces)
- 1/2 cup walnuts
For the topping:
- 1/3 cup sugar
- 1 1/2 tbsp butter (I like Kerrygold unsalted butter for this)
- 1 tsp cinnamon
Step 1: Prepare Equipment and Mise en Place
- 2 cups rhubarb
- 1/2 cup walnuts
Preheat your oven to 350°F and grease your muffin pan(s) with butter or cooking spray.
While the oven preheats, chop the rhubarb into 1/2-inch pieces and coarsely chop the walnuts.
Set both aside—keeping the rhubarb separate prevents it from releasing too much liquid into the batter before baking.
Step 2: Combine Dry Ingredients
- 3 1/4 cups flour
- 1 tsp baking soda
- 1 1/4 tsp baking powder
- 1/2 tsp salt
In a medium bowl, whisk together the flour, baking soda, baking powder, and salt.
Whisking aerates the flour and ensures the leavening agents are evenly distributed throughout, which gives you muffins with consistent rise and a light crumb.
Step 3: Mix Wet Ingredients
- 1 cup brown sugar
- 1 cup buttermilk
- 1/2 cup vegetable oil
- 1 egg
- 1 1/2 tsp vanilla
In a separate bowl, whisk together the brown sugar, buttermilk, vegetable oil, egg, and vanilla until well combined and smooth.
The buttermilk reacts with the baking soda to create lift, so make sure everything is fully incorporated before moving to the next step.
Step 4: Combine Wet and Dry Mixtures, Then Add Fruit and Nuts
- dry ingredient mixture from Step 2
- wet ingredient mixture from Step 3
- 2 cups rhubarb from Step 1
- 1/2 cup walnuts from Step 1
Pour the wet ingredient mixture from Step 3 into the bowl with the dry ingredients from Step 2 and stir gently until just combined—don’t overmix, as this can lead to tough muffins.
Once the batter just comes together, fold in the chopped rhubarb and walnuts.
I like to add the rhubarb at this stage rather than earlier because it stays fresher and releases its tart flavor more effectively when it mixes directly into the batter.
Step 5: Make Cinnamon Sugar Topping and Fill Muffin Cups
- batter from Step 4
- 1/3 cup sugar
- 1 1/2 tbsp butter
- 1 tsp cinnamon
While preparing the topping, divide the batter evenly among the muffin cups, filling each about two-thirds full.
In a small bowl, combine the sugar, butter (softened or melted), and cinnamon until it forms a crumbly mixture.
Sprinkle the cinnamon sugar topping generously over each muffin, pressing it gently so it adheres to the batter.
Step 6: Bake and Cool
Bake in the preheated 350°F oven for 25 minutes, until the tops are golden brown and a toothpick inserted into the center of a muffin comes out with just a few moist crumbs (not completely clean, as the rhubarb will still be slightly moist).
Remove from the oven and let the muffins cool in the pan for 10 minutes before turning them out.
This resting period allows the structure to set just enough so they release cleanly from the pan without breaking apart.
