“Thank you for this lovely, simple recipe! Made the rhubarb cake according to instructions and knew right away that I should have made two. ~Nancy
an easy rhubarb cake for breakfast and beyond
The texture of this cake is just perfect, it’s not too sweet, and the tart rhubarb gives it a unique flavor. There’s a nice background note of vanilla in the batter which plays really well with the rhubarb. And then there’s that slightly crunchy sugary crust ~ this rhubarb cake is divine whether you have it for breakfast, snack on it all day, or save it for dessert.
ingredients for rhubarb cake
You’ll just need a few stalks of rhubarb for this breakfast cake recipe, enough to make 2 cups of thin slices. The red color is beautiful, but green rhubarb will give you wonderful flavor too.
- rhubarb
- fresh is best but you can use frozen sliced rhubarb if you have it. If you do use frozen rhubarb, don’t thaw it first or it can become soggy.
- butter
- I always bake with unsalted butter. If you only have salted on hand, just leave out the extra salt in the recipe.
- granulated sugar
- I sprinkle a little extra over the cake before baking which creates a light crunch to the crust.
- egg
- half & half, cream, or buttermilk
- use them interchangeably according to what you have in the fridge.
- all purpose flour
- baking powder
- salt
- lemon juice
- vanilla
- the vanilla and tart rhubarb make a wonderful flavor combo, but I also love it with almond extract, so use your favorite.
Rhubarb FAQs
Is rhubarb a fruit or a vegetable?
- Rhubarb is a tart vegetable (it’s part of the buckwheat family!) that we treat as a fruit in cooking. It grows in long leafy stalks, and kind of looks like red celery. The stalks can be harvested when very young, or when large and mature. Do not eat rhubarb leaves, they are poisonous. They contain oxalic acid, which is toxic to humans.
When is rhubarb season?
- Rhubarb season is April through June, but you’ll see if sooner and later in some areas. Rhubarb is one of the first veggies of spring.
Is rhubarb healthy?
According to Healthline…“Rhubarb is a good source of fiber and antioxidants. Studies show that rhubarb fiber may lower cholesterol.”
Rhubarb is low in calories and high in fiber, making it a great choice for those watching their weight or looking to improve their digestive health. It is also a good source of vitamin K, which is important for bone health.
Why is my rhubarb green?
- Rhubarb varies in color from deep crimson to pale green. Newer varieties, like my Cherry Red rhubarb, is bred for its sweet flavor and intense color, which is nice because that’s one of the things we love about rhubarb and it’s a big drag when the color doesn’t bloom in recipes. There is little difference in flavor between the green and red, but red rhubarb can be stunning when cooked.
How to cook rhubarb?
- Rhubarb can be cooked in a variety of ways, including stewing, baking, and poaching. It is often used in pies, crisps, and crumbles, as well as in sauces and jams. To cook rhubarb, simply cut off the leaves and the tough bottom end of the stalks, then chop them into small pieces and cook them with sugar until they are soft and tender. For cakes and muffins you use raw rhubarb, just slice the stalks to the size needed for your recipe.
Can you freeze rhubarb?
- Rhubarb freezes beautifully. Slice it and lay it out on a parchment paper lined baking sheet. Put the pan in the freezer and freeze until solid. Then transfer the rhubarb to a freezer style zip lock baggie or airtight container.
Do I need to thaw rhubarb before using?
- In most cases there’s no need to thaw the rhubarb when you want to use it for cooking, or baking, just use it frozen.

Rhubarb Cake
My Rhubarb Cake recipe is a classic ~ the kind your grandma made, if you were lucky. It's packed with jammy bits of sweet/tart rhubarb and it's officially my favorite way to start the day.
Servings: 12 servings
Equipment
- 9×9 square baking pan
Ingredients
- 1/2 cup half and half, cream, or buttermilk
- 1 tsp lemon juice
- 1/2 cup unsalted butter at room temperature
- 1 cup granulated sugar plus 2 tsp for sprinkling
- 1 large egg, at room temperature
- 1 1/2 tsp vanilla extract
- 2 cups all purpose flour, saving out 1 Tbsp to toss with rhubarb
- 2 tsp baking powder
- 1 tsp salt
- 2 cups thinly sliced rhubarb
Instructions
- Preheat the oven to 350F Lightly butter a 9×9 square baking pan. I like to line the pan with parchment paper with overhanging ends so I can easily lift out the cooled cake for cutting. That's optional.
- Stir the lemon juice into the half and half and set aside.
- Cream the soft butter and sugar in a stand mixer, or with electric beaters, until fluffy and pale yellow. Beat in the egg and vanilla, scraping down the bowl as necessary.
- Take 1 Tbsp of the flour to the rhubarb and toss well.
- In a separate bowl whisk together the remaining flour, baking powder, and salt.
- Add half of the flour mixture to the bowl and blend in. Add all of the half and half, and blend in. Finally add the rest of the flour and blend just until combined, don't over mix. Fold in the rhubarb. Note: the batter is on the thick side.
- Spread the batter into the prepared pan and sprinkle the top evenly with a little sugar. Bake for about 40-45 minutes, or until the cake is turning golden and a toothpick in the center comes out without wet batter clinging to it (moist crumbs are fine.)
- Let the cake cool slightly before cutting.

Notes
- Other fruit like berries work beautifully in this rhubarb breakfast cake. Also try chopped banana.
- Mix the topping sugar with a touch of cinnamon for a hint of spice.
- For a lower fat option try buttermilk in place of the half and half and lemon. Half Greek yogurt and half milk would work, too.

This was my first go with rhubarb and it was delicious! I had a few tweaks and it still turned out perfect! I used 1 cup of Gluten free flour and 1 cup oats, cut the sugar to 2/3 cup and used evaporated milk in place of the half and half. It must be a very forgiving recipe because it tastes like it was meant to be!
Thanks for that great info Sheila, I don’t know if anyone else has successfully made it gf, so that’s useful to know.
So good! What a nice cake. Next time I may add some chopped walnuts. This was my husband’s first introduction to rhubarb, and he thinks it’s great!
Thanks Silva!
Have made this cake twice and it has been delicious both times! The only problem I seem to have is that my oven needs almost twice as long to bake this as the recipe calls for – but I know the temperature is off so that might just be my problem. I use buttermilk instead of the half & half with lemon juice and dice up the rhubarb stalks (fresh from a coworker!). It’s my first time cooking with rhubarb and this cake definitely made me a convert! Thank you so much for sharing!
Thanks for coming back to share your feedback Melissa ~ you might want to invest in an oven thermometer, they’re cheap, and from my experience most ovens are off in some way.
~ and rhubarb-sharing coworkers are the best kind 🙂
Hi there, what is half and half please? Looking forward to trying this
Half and Half is simply half whole milk and half heavy cream. You can make it yourself, but all US stores carry it. If you’re in Europe or the UK, look for half cream, or single cream.
Hi Sue
can you please explain what ‘half and half’ is? Looking forward to making it but want to get it right!
Half and Half is an American product that is basically half heavy cream and half milk. It’s close to half cream (Europe) or single cream in the UK. You can make it yourself by just mixing whole milk with heavy cream 🙂
OMG! I’m in heaven. This cake is delicious; moist, flavorful, and easy to make. It is sure to become a household favorite (if I leave any for others to taste!). I could also see this as the perfect “come over for coffee ” treat. Add a spoon of yogurt on the side? Certainly not necessary, but a thought.
Thank you.
Yes, definitely a come over for coffee kind of recipe, my favorite kind! Thanks Jane 🙂
I’d like to make this as a bundt cake? Any suggestions. I’ve never baked a bundt cake before but thought it would be nice to take to my office.
Hi! I didn’t have a 9″ x 9″ pan, and I just happened to use a bundt pan, and it worked well, but it shortened the cooking time to 30 minutes. The cake was short enough I could’ve doubled the recipe, then it would probably need to bake for the 40 to 45 minutes. I didn’t sprinkle it with sugar, being that it would end up on the bottom, but I think It would look very nice dusted with a little powdered sugar on it.
This sounds delicious! Could this recipe be baked in muffin cups, and reducing the bake time?
Yes, that should work nicely.
Sounds like a great recipe !! I can not wait for the rhubarb to start growing. I’m wondering if I can make this in a muffin form. I’ll give it a try !
I think this would do fine as muffins 🙂
Rhubarb Breakfast Cake is very delicious! 5 star delicious 🙂
I found frozen rhubarb in my freezer from spring 2018 and used it today. Tossed with flour while still frozen and added to recipe.
Thanks Tammy, I just featured your nice comment on my homepage 🙂
Sue, thank you for sharing this! I have made this so many times. Everyone that tries it, loves it!
Thanks so much Polly, I’m so glad it is a hit for you!
