Rhubarb muffin recipe makes a moist sweet and tender muffin loaded with fresh rhubarb under a warm and crunchy brown sugar cinnamon streusel topping.
Rhubarb is one of the first things to pop up once the weather gets warmer. We love the stuff and these Rhubarb Muffins with Cinnamon Butter Crumble is one of the first things I make whenever I get my hands on some.
It’s time for the Spring version of “The Freaky Friday” blog hop, and I’m bringing Rhubarb Oat Muffins with Cinnamon Butter Crumble to the party!
The Freaky Friday blog hop organized by Michaela who runs An Affair From the Heart, is a group of bloggers that are secretly assigned each others’ blogs from which we choose a recipe.
It is so much fun, and the bloggers that participate are all amazing foodies. The biggest problem I always have is picking just one recipe to post about.
This time I had the pleasure of being assigned Michele’s blog “Bacon Fatte“. Michele is a Minnesota gal who doesn’t apologize for her use of bacon, butter, or booze.
How can you not love someone like that? Michele does an amazing job making colorful dishes for the family and some amazing entertaining cuisine.
Our selection needed to be springy was the only stipulation. You know me, guess what my search gravitated toward?
These muffins have such a beautiful contrast between the sweetened rhubarb and warm cinnamon and brown sugar.
Even though the batter is quite thick they bake up soft and tender. They’re perfect with a cup of coffee for breakfast or a special treat with dinner. They’re easy to put together and makes up to 24 muffins!
How to make Rhubarb Muffins
There are two steps to making these muffins. I make the Streusel top first and just set it aside. Let’s start with it.
Cinnamon Brown Sugar Streusel Topping
- Combine flour, old-fashioned oats, brown sugar, cinnamon, and turbinado sugar together in a small bowl.
- Dice cold butter. Using two forks or a pastry cutter, cut the butter into the dry ingredients until it appears crumbly. Set aside (I put mine in the refrigerator).
- Don’t overwork it or it will blend together and not crumble over the muffin.
- Don’t use your fingers. The heat in your hands will soften the butter and break down your crumble.
- In a large bowl combine the dry ingredients, flour, brown sugar, cinnamon, oats, baking soda, and salt. Whisk together until blended.
- In a separate bowl combine the wet ingredients, milk, vinegar, vanilla extract, oil, and egg. Whisk together.
- Add the wet ingredients to the dry ingredients using a spatula. Mix only until combined.
- Fold in the rhubarb.
- Fill muffin cups 3/4 full. Sprinkle with additional rhubarb pieces and crumble. For an extra crunch sprinkle with the top with turbinado sugar.
Tips for the perfect muffin
- Chop the rhubarb into smaller pieces to ensure that it disperses evenly and bakes evenly.
- Milk and vinegar listed in the ingredients can be replaced with buttermilk.
- Don’t over mix the crumble or the batter, mixing only as long as necessary. Over mixing will result in a tough muffin.
- You can use frozen rhubarb. Frozen rhubarb holds a lot of moisture and should ve thawed and extra moisture lightly pressed before using it.
- Turn the muffin pan halfway through baking to assure muffins bake evenly. Remove the muffins when a toothpick or cake tester comes out with light crumbs.
- Let the muffins cool in the pan 10 minutes and then remove them from the pan.
- It’s best to use two pans but if you only have one, make sure it’s cool before refilling it.
Storing Rhubarb Muffins
Muffins are best stored in a cake carrier or covered container once they’re completely cool. They don’t do well in a plastic bag because the crumble will become soggy. Muffins freeze well in an airtight container.

Rhubarb Oat Muffins with Cinnamon Butter Crumble
Cinnamon Butter Crumble
- 1/4 cup unsalted butter chilled and cut into 1/4″ pieces
- 1/4 cup unbleached all-purpose flour
- 1/4 cup old-fashioned oats
- 2 tbsp brown sugar
- 1 tsp ground cinnamon
- 1 tsp turbinado sugar optional (sugar in the raw)
- 2-1/2 cups unbleached all-purpose flour
- 1-1/4 cups brown sugar I used dark brown sugar but either is fine
- 1 cup old-fashioned oats
- 1 tsp baking soda
- 1 tsp salt
- 1 tsp cinnamon
- 1 cup whole milk
- 1 tsp white vinegar or lemon juice
- 1 tsp vanilla extract
- 1/2 cup vegetable oil or canola
- 1 egg lightly beaten
- 2 cups rhubarb chopped – reserve 1/4 cup for topping
- Preheat oven to 350°F. Line two standard muffin pans with cupcake liners or spray with a non-stick cooking spray.
Cinnamon Butter Crumble
- Combine crumble ingredients in a small bowl. Use two forks to cut butter into other ingredients. I used my fingers and “pinch” the ingredients together until it resembles coarse crumbs. If the butter gets to warm it will not crumble. Refrigerate before crumbling it gets too soft.
- In a large mixing bowl add flour, brown sugar, cinnamon, oats, baking soda, and salt. Whisk together to combine.
- in a medium bowl combine milk, vinegar, vanilla extract, oil, and egg. Whisk together.
- Add wet ingredients to dry ingredients and mix together until just combined. Fold in 1-3/4 cups chopped rhubarb.
- Fill muffin cups 1/2 to 3/4 full. Top with remaining rhubarb and crumble. Sprinkle with turbinado sugar.
- Bake 20 to 25 minutes rotating pans halfway through baking. Remove from the oven when a toothpick inserted in the middle of the muffin comes out clean. Cool muffins 10 minutes in the pan and then remove them to a baking rack to finish cooling or serve warm.
- Store in an airtight container at room temperature or in the refrigerator. May be frozen for a longer period of time.
