Rhubarb Muffins with Cinnamon Sugar

Updated: Mar 3, 2023

Plate of Rhubarb Muffins

It's always rhubarb season at my house! I can always count on my plant every spring. It's very generous!

I simply pick, wash, chop and freeze it for later use, then there's plenty of rhubarb to enjoy all year long. I used up my rhubarb from last summer to make these muffins in May.

This is the most simple muffin recipe. Just put all ingredients into one bowl, stir and bake! It's a perfect recipe to make with your kids, or for your older kids to make themselves.

They muffins are bursting with that tangy rhubarb flavour and the sprinkle of cinnamon sugar creates a crunchy muffin top!

Ingredients for rhubarb muffins


1 egg

1 cup buttermilk*

½ cup vegetable oil

2 tsp vanilla

1 ½ cup brown sugar

½ cup quick oats (optional)

1 ½ cup all-purpose flour

1 cup whole wheat flour

1 tsp baking powder

1 tsp baking soda

½ tsp salt

5 cups chopped rhubarb

½ cup chopped walnuts (optional)

2 tbsp white sugar

1 tsp cinnamon


  1. Preheat oven to 375° F.

  2. In a large mixing bowl, whisk together egg, buttermilk, oil, vanilla and brown sugar, until smooth.

  3. Stir in dry ingredients (oats, flour, baking powder, baking soda and salt), until all incorporated. Be careful not to overmix.

  4. Fold in rhubarb and walnuts.

  5. Spoon into prepared muffin tins (use paper liners to avoid sticking).

  6. Mix sugar and cinnamon together in a small dish.

  7. Sprinkle each muffin with cinnamon sugar.

  8. Bake for 25 minutes or until golden brown and a toothpick comes out clean.

*If you don't have buttermilk, mix 1 tbsp of white vinegar or lemon juice with 1 cup milk. Stir and let sit for 5 minutes before using.

NOTE: You could easily turn these into blueberry muffins by replacing the rhubarb with 3 cups of blueberries.

They make the perfect snack, or pair with yogurt and some fruit for a quick breakfast!

This is a great recipe for KIDS to help make. Get them to gather ingredients and equipment, measure, stir, spoon into the muffin tins, and sprinkle with cinnamon sugar. They'll love being involved and maybe one day they'll make muffins for you!

Kids who are involved in cooking, tend to be more interested in trying new foods.

If you love rhubarb, you're going to love these muffins!
