Ingredients You’ll Need

The magic of Rhubarb Muffins with Cinnamon Sugar Topping comes from simple ingredients that shine together. Each one is picked for a reason—whether it’s tenderness from sour cream, the zing of fresh rhubarb, or that buttery, cinnamon-laced crown that everyone reaches for first.

• All-purpose flour: The hearty base for tender muffins, sturdy enough to hold in all that lush rhubarb.
• Granulated sugar: Brings sweetness and helps the muffins brown to golden perfection.
• Baking powder: Lifts the muffins for that perfect domed top.
• Baking soda: Works with the sour cream to add just a bit more rise and softness.
• Salt: Balances flavors and highlights the tangy and sweet elements.
• Ground cinnamon: Infuses warmth into the muffins and creates an aromatic topping.
• Sour cream: Adds richness and keeps the crumb perfectly moist.
• Unsalted butter, melted: For that unmistakable home-baked, buttery taste.
• Vegetable oil: Helps the muffins stay soft and moist even a day or two after baking.
• Large eggs: Bind everything together and add tender structure.
• Vanilla extract: Rounds out the flavors with a soft, sweet aroma.
• Fresh rhubarb, finely chopped: The star of the show—brings color, moisture, and a perfect tang.
• Topping: Granulated sugar: Creates a crisp, sparkling crown for the muffins.
• Topping: Ground cinnamon: Adds flavor and that unmistakable bakery charm.
• Topping: Butter, melted: Helps the cinnamon sugar stick and gives the topping a luscious finish.

How to Make Rhubarb Muffins with Cinnamon Sugar Topping

Step 1: Prep the Muffin Tin and Preheat the Oven

Begin by setting your oven to 375°F (190°C); baking at the right temperature ensures golden-topped muffins with a fluffy center. Line a 12-cup muffin pan with paper liners or give each cup a swipe of butter or nonstick spray so nothing sticks. Prepping the pan ahead helps things move smoothly when the batter is ready.

Step 2: Whisk Together the Dry Ingredients

In a large bowl, whisk the flour, sugar, baking powder, baking soda, salt, and ground cinnamon. Mixing the dry ingredients first guarantees even distribution, so each muffin puffs up beautifully and every bite has balanced flavor and a whisper of spice.

Step 3: Blend the Wet Ingredients

In a separate bowl, combine the sour cream, melted butter, vegetable oil, eggs, and vanilla extract. A quick whisk brings everything together until smooth and creamy—the sour cream ensures your muffins stay velvety, while the blend of butter and oil adds richness and softness.

Step 4: Bring the Batter Together

Pour the wet ingredients into the bowl of dry ingredients, stirring gently just until combined. Over-mixing at this stage can make your muffins tough, so a few flour streaks are fine. The goal is a lumpy, thick batter that promises a tender crumb once baked.

Step 5: Fold in the Rhubarb

With a spatula, gently fold in the chopped rhubarb until evenly distributed. The rhubarb brings those pops of color and fresh sour flavor, making each muffin truly special. Try not to overwork the batter; just a quick fold does the trick.

Step 6: Fill the Muffin Cups

Divide the batter evenly among the prepared muffin cups—about two-thirds full for each. Using an ice cream scoop or large spoon makes the job quick and less messy, and ensures every muffin bakes up the same size.

Step 7: Mix the Cinnamon Sugar Topping

In a small bowl, stir together the granulated sugar and ground cinnamon for the topping. This simple step adds that bakery-shop sparkle and a hint of spice that elevates the entire batch of Rhubarb Muffins with Cinnamon Sugar Topping.

Step 8: Butter and Sprinkle

Brush the tops of each unbaked muffin with a little melted butter, then generously sprinkle each with the cinnamon sugar mixture. The butter helps the topping stick while lending a rich aroma as it bakes.

Step 9: Bake to Perfection

Slide the muffin tin into your preheated oven and bake for 20 to 25 minutes, or until a toothpick inserted in the center comes out clean. The tops should be golden, sparkling, and just a touch crisp.

Step 10: Cool and Enjoy

Let the muffins cool in the pan for five minutes, then carefully transfer each one to a wire rack. This quick rest allows them to finish setting up without steaming the bottoms, so every muffin stays light and fluffy.

How to Serve Rhubarb Muffins with Cinnamon Sugar Topping

Garnishes

Try dusting your muffins with a little extra cinnamon sugar or a sprinkle of powdered sugar right before serving. For a burst of color, add a few tiny pieces of diced rhubarb to the plate, or even a gentle drizzle of honey if you want a glossy finish—all easy ways to give Rhubarb Muffins with Cinnamon Sugar Topping a show-stopping look.

Side Dishes

Pair these sweet-tart treats with Greek yogurt and fresh berries for a refreshing breakfast, or serve them alongside soft scrambled eggs for brunch. A piping hot cup of coffee, black tea, or even cold milk will complement the delicate spice and buttery crumb perfectly.

Creative Ways to Present

If you’re feeling playful, slice each muffin and spread with a little cream cheese or homemade jam. You could also pack them in a picnic basket with a jar of honey and see these Rhubarb Muffins with Cinnamon Sugar Topping disappear at the park. For a giftable touch, nestle a few in a parchment-lined basket and wrap with twine for a homemade surprise.

Make Ahead and Storage

Storing Leftovers

Once completely cooled, keep your muffins in an airtight container at room temperature for up to three days. A slice of bread added to the container will help absorb excess moisture and keep the cinnamon sugar topping soft but not soggy.

Freezing

Rhubarb Muffins with Cinnamon Sugar Topping freeze surprisingly well. Simply wrap each muffin individually in plastic wrap, then pop them all in a freezer bag for up to two months. Thaw overnight at room temperature for a grab-and-go breakfast that tastes as fresh as the day they were baked.

Reheating

To revive that just-baked warmth, reheat muffins in a 300°F (150°C) oven for about 10 minutes, or microwave for 20 seconds. This brings back the softness and lets that cinnamon sugar topping glisten like new.

FAQs

Can I use frozen rhubarb instead of fresh?

Absolutely! Just make sure to thaw and drain the frozen rhubarb thoroughly before folding it into your batter. This keeps the muffins from turning out soggy and ensures every bite has that perfect burst of tart fruit.

What can I use instead of sour cream?

Plain Greek yogurt is a wonderful substitute for sour cream in this recipe. It brings just as much moisture and tang, so your muffins stay tender and flavorful—no one will ever know the swap.

Can I make these muffins gluten-free?

Yes, you can use a 1-to-1 gluten-free flour blend to replace the all-purpose flour. Stick to mixes that contain xanthan gum for the best texture and structure in your Rhubarb Muffins with Cinnamon Sugar Topping.

How do I prevent the muffins from sticking to the liners?

If you don’t want to risk any sticking, opt for parchment paper liners or spray your regular liners lightly with nonstick spray. Letting the muffins cool a bit before peeling also helps keep that lovely crust intact.

What if I don’t have muffin liners?

You can grease your muffin tin well with butter or nonstick spray—no need for liners. The finished muffins might have a slightly more golden, crisp edge, which is a treat all its own!
