This simple Rhubarb Cake recipe is one I look forward to all year. Packed with rhubarb and simple pantry ingredients, it’s a long-time family recipe we’ve been making for a couple of generations. For us, it’s a delicious summer ritual!
I adore spring for its beauty and freshness, and the new life it brings to our world.
But I also love it for rhubarb, a sentiment it took me a few years to embrace. But this Rhubarb Cake changed all that. It’s delicious and yummy, even for non-rhubarb lovers.
When I begin to see stalks of crimson rhubarb lining the produce shelves at my favorite market, I truly know as Frog said to Toad — “Spring is just around the corner.”
I’ll never forget the first time I had this cake. It was a sweltering Saturday and a family reunion in Yakima, Washington. Muggy and hot. I’m not a fan of humidity. And it was so humid that day. But then I tasted this cake, dusted with cinnamon sugar. It was more delicious than I can tell you.
The recipe is from cousin Marilyn’s mother. Passed down through their family tree.
When I asked, maybe begged for the recipe… cousin Marilyn sweetly said, “Yes.”

What Does Buttermilk Do For Baked Goods?
Buttermilk brings a pleasing tang to baked goods like cakes, breads, biscuits, pancakes, and more. Much like yogurt and sour cream, it helps the cake rise due to its acidic nature. It also bring a softer texture to baked goods and gives them additional body.
How To Make Your Own Buttermilk
- Add 1 tablespoon vinegar (or lemon juice) to a 1 cup measure.
- Fill the rest of the 1 cup measurement with milk.
- Stir and let sit at least 5 minutes until it begins to curdle and thicken.
