Rhubarb Muffin Cake

The North Iowa farmers markets are open again and I spy rhubarb, so summer may begin now.

Unlike the Twin Cities, we don’t have a farmers market in every neighborhood, but I’m happy we have one in town. The Mason City farmers market isn’t large and there aren’t food trucks or anything, but I can at least buy fresh vegetables and fruits, plus extra treats like bread, jam, and bags of puppy chow mix.

There’s also a vendor that sells grilled brats with the typical fixings of sauerkraut, onion, ketchup, and mustard. This is a simple pleasure that never gets old. I rarely turn down street meat.

On my last two visits, I rejoiced over this summer’s first bounty of rhubarb like the good Midwesterner that I am.

We never cooked with rhubarb growing-up. Nobody in our neighborhood grew it and I think they considered it like a weed. Jake remembers picking it as a child and eating the tart stalks dipped in sugar. As an adult, I’ve become taken with rhubarb. I love how it retains some tartness when cooked and balances out sweet desserts. The complexity of its unique flavor strikes me as both fruity and floral.

I asked friends for their favorite rhubarb recipes, but chose this cake because I had all of the ingredients in my kitchen. I found variations of this recipe in nearly all of my cookbooks, so, where it truly originates, I do not know. This cake is very simple to prepare and light and fluffy like a muffin. It reminded us so much of muffins, that I poured the batter into muffin tins the second time I made it.

This cake will be an ol’ reliable for us. Now I’m moving on to trying everyone’s favorite rhubarb recipes.

Cook’s Notes: The original recipe calls for 1 1/2 cups of white or brown sugar. I used both, but in lesser amounts. The original recipe also calls for buttermilk, which I did not have. It says you can substitute one cup of regular milk + one tablespoon of lemon juice for buttermilk. In my first cake, I used 2/3 almond milk + 1/3 cup sour cream. In my muffins, I used only almond milk. I think you can use whatever you have, though the sour cream adds extra moistness. If you’d like to bake muffins, reduce the cooking time. Mini muffins took about 10 minutes. The cakes are done when you can cleanly remove a toothpick from the center.

A scant 1 cup white sugar
1/2 cup brown sugar, not packed.
1/2 cup butter (1 stick). I used salted.
1 egg
1 teaspoon vanilla extract
Optional: Splash of almond extract
1 cup milk or combination of milk + sour cream
2 cups unbleached, all purpose flour
1 tsp. baking soda
1/2 teaspoon salt
2 cups of rhubarb, chopped into small pieces
Topping: sugar & cinnamon


  1. Pre-heat the oven to 350℉.
  2. Combine the flour, baking soda, and salt in a bowl and set aside.
  3. In a large bowl, cream together the butter and sugars.
  4. Mix the egg and vanilla extract into the butter-sugar mixture.
  5. Add the milk and dry ingredients to the butter-sugar mixture, half at a time, alternating until just combined. Don’t overmix.
  6. Stir in the rhubarb.
  7. Pour into a greased pan or muffin tins. Sprinkle lightly with cinnamon and sugar (or just cinnamon).
  8. Bake until you can remove a toothpick cleanly from the center. A small cake pan took about 45 minutes, a 9×13 will take about 35-40 minutes, and muffins will vary depending on the size. Mini muffins took about 10 minutes.

    I am baking up rhubarb recipes like crazy over here too. I love the idea of muffins though. That might be my next treat as I still have 4 cups waiting for me in the freezer. Thanks for sharing!

      That reminds me, I should figure out how to freeze it!

      • MotherMaier

        Easy-peasy! Cut rhubarb stalks into 1/2-1 inch pieces, depending on width of stalk. Measure the amount typically used in a recipe and place in zip-top freezer bag. Flatten bag so pieces aren’t clumped together. Lay flat in freezer to store and enjoy in your favorite recipes after rhubarb season has ended. Alternatively, you can place cut rhubarb in a single layer on a cookie sheet, place in freezer for several hours until solidly frozen. Then package in larger zip-top bags and measure out the necessary amount for a recipe. For most recipes, I use it in the frozen state when adding to the other ingredients. It does become “watery/mushy” when completely thawed and then is best used in a cooked sauce or jam. Hoping these tips are helpful!

          Thanks for the instructions! It will be nice to have frozen rhubarb in the winter. A couple years ago, I made a rhubarb sugar syrup that I added to seltzer or tonic water. I need to figure out how I did that again.

    I need to get some rhubarb……we grew up having rhubarb everything and I love it. Maybe a strawberry rhubarb pie??? Rhubarb crisp? Don’t you think it is a funny word—rhubarb??? It is one of those words that never looks correct when I write it….

    • Jeni Flaa

      I need to make up for lost rhubarb time. It is a funny word!

    Love, love rhubarb! My favorite things to make are rhubarb cobbler and sour cream rhubarb pie. Look forward to both every spring. I’m fortunate to have a huge patch in my backyard. I will have to try this recipe soon.

    • Jeni Flaa

      I just saw a recipe for sour cream rhubarb pie in a church cookbook and thought it looked great. Wish I had some in my backyard.

      • Kristin

        I’d ask around. I’m always surprised at how many people in my little town have it and don’t use it. They are usually happy to let someone come and pick it for free. My recipe only needs 3 cups.

    I’m not a big rhubarb person, but this looks good. I think I’d like it and definitely want to try it.

      You could probably chop it up super small and it would mostly taste fruity. Hope you like it!
