How to Make Rhubarb Muffins with Cinnamon Sugar Topping Recipe
Step 1: Prepare the Oven and Muffin Tin
Start by heating your oven to 375°F (190°C). Line your muffin tin with paper liners or lightly grease it to prevent sticking. This first step ensures your muffins bake evenly and come out with perfectly soft bottoms.
Step 2: Mix Dry Ingredients
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt, and cinnamon. This combination will give your muffins their rise, flavor balance, and that warm cinnamon charm.
Step 3: Combine Wet Ingredients
In another bowl, whisk the melted butter, buttermilk, eggs, and vanilla extract until they come together into a smooth, luscious mixture. These ingredients ensure moisture and richness in every bite.
Step 4: Blend Wet and Dry Ingredients
Pour the wet mixture into the bowl with the dry ingredients. Stir gently until just combined. Be careful not to overmix because you want tender muffins, not dense ones.
Step 5: Fold in the Rhubarb
Delicately fold the chopped rhubarb into the batter. This makes sure the fruit is evenly distributed so every muffin bursts with that signature tartness.
Step 6: Fill the Muffin Cups
Divide the batter evenly among the muffin cups, filling each about three-quarters full. This allows space for the muffins to rise without spilling over.
Step 7: Add the Cinnamon Sugar Topping
Mix together the sugar and cinnamon for the topping, then sprinkle it over each muffin cup generously. This topping bakes into a slightly crunchy and sweet crust that’s a dream to bite into.
Step 8: Bake Until Golden
Bake your muffins for 20-25 minutes or until a toothpick inserted in the center comes out clean. You’ll know they’re done when they’ve risen beautifully and have a subtle golden hue.
Step 9: Cool Before Enjoying
Let your muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely. This step is essential to let them finish setting and makes sure they don’t feel too soft or gummy when eaten.
How to Serve Rhubarb Muffins with Cinnamon Sugar Topping Recipe

Garnishes
While these muffins already shine on their own, a light dusting of powdered sugar or a thin spread of softened butter just after baking can add an extra touch of indulgence. Fresh raspberry or strawberry slices also pair beautifully on the side to complement the rhubarb.
Side Dishes
These muffins make a fantastic partner to morning coffee or afternoon tea. Try serving them alongside a creamy yogurt parfait or a light fruit salad to create a balanced, refreshing meal.
Creative Ways to Present
For a brunch or dessert display, arrange the muffins on a rustic wooden tray with small bowls of whipped cream and honey for guests to customize. You can even halve a muffin and layer it with lemon curd and fresh herbs for a surprising twist.
Make Ahead and Storage
Storing Leftovers
Leftover Rhubarb Muffins with Cinnamon Sugar Topping Recipe stay fresh when stored in an airtight container at room temperature for up to 2 days. Avoid refrigeration as it can dry them out, but if needed, bring to room temperature before eating.
Freezing
Freeze any uneaten muffins by wrapping them individually in plastic wrap and placing them in a freezer bag. They keep well for up to 3 months and thaw quickly, preserving their moist texture and cinnamon-sugar crunch.
Reheating
Reheat frozen or room-temperature muffins in a 350°F (175°C) oven for about 8 minutes, or microwave for 20-30 seconds until warm. This refreshes their tender crumb and revives that irresistible cinnamon sugar top.
FAQs
Can I substitute rhubarb with another fruit?
Absolutely! While rhubarb’s tartness is unique, chopped strawberries or tart cherries can provide a similar fresh tang. Adjust sugar accordingly if you prefer sweeter muffins.
Do I have to use buttermilk?
Buttermilk adds moisture and activates the baking soda. If you don’t have buttermilk, mix 1 cup milk with 1 tablespoon vinegar or lemon juice and let it sit for 5 minutes before using.
Can I make these muffins gluten-free?
You can experiment with a gluten-free flour blend that includes xanthan gum, but the texture may differ slightly. Always follow your blend’s instructions for best results.
How long do these muffins stay fresh?
Properly stored at room temperature, these muffins remain delicious for about 2 days. For longer storage, freezing is recommended to maintain freshness.
What if I want a less sweet topping?
Feel free to reduce the topping sugar or simply sprinkle cinnamon alone. The tart rhubarb keeps the balance, so less sweetness still tastes fantastic.
