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.

I had a heck of a task trying to decide on which recipe to make. Her Linguine con le Vongole and her New Potato Salad with Basil, Shallots, and Lemon were all contenders.
Our selection needed to be springy was the only stipulation. You know me, guess what my search gravitated toward?
Yep, bread and Michele didn’t disappoint. I had my eye on her Spiced Bakery Style Ginger Pear Muffins but her Rhubarb Oat Muffins with Cinnamon Butter Crumble were the ultimate winner.

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.
Muffin Batter
- 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.
Assemble/Finish
- Fill muffin cups 3/4 full. Sprinkle with additional rhubarb pieces and crumble. For an extra crunch sprinkle the top with turbinado sugar.
- Bake
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.

Just made these with the following substitutions: 1/2 c oil became 1/4 c oil + 1/4 c plain Greek yogurt 11% MF; 1 c milk became 1/2 c plain Greek yogurt 11%MF + fill to 1c with milk (happen to have 1%); for crumble I used salted butter (thats what i had thawed) then cut the salt in the dry ingredients to just under 1/2 tsp. They turned out great but leaning to the moist side. I also use large flake oats ALWAYS when baking as I find they give a more wholesome texture. Additionally, tsp cinnamon = 1 heaping tsp cinnamon whenever I bake haha. I usually leave rhubarb chunks large as I do like the tangy bite but don't mind these being more mild on the rhubarb flavour (my rhubarb was frozen). Probably would be good with a few other 'winter' spices (cloves, nutmeg, allspice etc) but I found the cinnamon flavour came through nicely as was perfect as is. I found the recipe is under yield for 24 muffins. Only filled 21 cups for me (tip add water to baking cups that remain empty in your tray to keep things more moist). Now to try and avoid eating them all before tomorrow's baby club!

I'm sorry to say we didn't really enjoy these muffins. They are far too sweet for our liking. I'm not a good enough baker to know how much sugar I can omit without affecting the end product (e.g., too dry, too crumbly). As another reviewer said, some extra spice like nutmeg would jazz up the flavour. The whole purpose of a rhubarb muffin is to enjoy the tartness of the rhubarb. This recipe missed the mark.

I'm sorry it wasn't for you. You can eliminate as much sugar as you want. If you found it too sweet, start with half and go from there. Thank you for letting me know.

Not sure what these muffins are suppose to taste like but they are bland and doughy. After 25 min in the oven they were quite raw and doughy. Had to cook them 12-15 min longer but they were still very bland.

That's really odd. I've not had anyone with this complaint. You may want to check your oven temperature's accuracy?

I haven't tried them yet, but it looks great. I just found it interesting that under the Cinnamon Brown Sugar Streusel Topping, you say, "Don’t use your fingers. The heat in your hands will soften the butter and break down your crumble.", and in the recipe say, " I used my fingers and “pinch” the ingredients together until it resembles coarse crumbs.

Thanks for pointing that out for me Marsha! It does work better if you don't use your fingers because the butter is what creates that crunchy crumble and if it's to soft or melted it doesn't work as well. I'll jump over and make that correction and sincerely thank you for pointing that out to me! ~Julie

These are amazing! My 3yo devoured them without a moments hesitation. I substituted 1/2c of the rhubarb for strawberries, but I bet they taste just as good as-is.

What a great tip, Lauren! I love it when the kiddos enjoy something I've made. Thank you!
