A moist and easy to make rhubarb cake topped with pecans and a delicious sweet cinnamon icing that compliments every bite!

It’s hard to imagine life before Pinterest. Chances are high that you found this recipe because of Pinterest!
In the ‘old’ days, I would look through my Mom’s recipe books or my Grandma’s recipe cards. Then my search evolved into looking to the internet for ideas. I would print off every single recipe I thought I would make and keep them in a 3-ring binder with post-it notes indexing them. I have so many that I had to make ‘best of’ categories so I didn’t have to flip through so many pages to find the recipe I was looking for! And I’ve had to clean it out and get rid of some because I can’t fit another recipe in the binder!
Then came Pinterest. Talk about a game changer. I didn’t have to print off recipes anymore! I think I was more excited about not having to 3-hole punch anymore. HA!

But the time came when I had saved TOO many recipes on Pinterest. In all seriousness, that isn’t possible. Anyway, I couldn’t easily find what I was looking for because I had saved so many. Thankfully I hang onto my trusty binder, because as pre-historic as it sounds I like being able to go to my post-it note tabs and find what I am looking for right away instead of trying to scroll through my saved recipes on Pinterest.
This recipe for Rhubarb Cake is one of my all-time favorites. I didn’t find it online; it was given to me years ago. So when I want to make it for rhubarb season I know exactly where to find it – in my trusty, tattered, and worn binder that has served me very well over the years!
It’s one of my favorite recipes, because:
- The cake is so moist, it melts in your mouth!
- It’s super easy to make.
- It works just the same if you use fresh or frozen rhubarb.
- The brown sugar gives the top of the cake the most delicious fragile crunch coat!
- Even if you don’t like rhubarb, you’ll love this cake!

How to Make Icing for Rhubarb Cake
- Combine 1 cup powdered sugar, 2 tbsp milk, 2 tbsp melted butter, and 1 tsp cinnamon. Mix together until smooth and runny. Add a little milk if you like it thinner.
- Pour over warm cake until covered.
Tips for Making Icing for Rhubarb Cake
- You can make the icing with or without the cinnamon.
- If you like a white icing, don’t add the cinnamon. The cinnamon will turn the icing light brown.
- I love using the cinnamon in the icing, it brings great flavor to the cake! I eyeball the cinnamon measurement, so sometimes I have added more or less. The cinnamon never disappoints!

Tips for Making and Storing Rhubarb Cake
- If you don’t love the idea of pecans on the cake, leave them off! Or, if you just want a few then just sprinkle on as many as you want.
- Cut up the rhubarb first. It will make putting the cake together much faster!
- Buy pecans that are already chopped, it will save you time!
- You can drizzle the entire cake with icing before serving, or you can drizzle each piece as the cake is being served. I prefer drizzling the entire cake before serving.
- You can store the cake covered in the refrigerator for up to 5 days.
- If you would like to freeze the cake, don’t put the nuts or icing on yet. Wait to add those after you remove the cake from the freezer.
- Freeze in a freezer safe container for up to 3 months.
