Rhubarb Cake
If you love rhubarb, you’ll adore this moist, fluffy Rhubarb Cake! It’s packed with tender chunks of rhubarb, the flavors of orange and vanilla, and it’s versatile enough to serve for dessert or brunch. It’s extremely easy to make and it takes about 15 minutes of prep time!
Rhubarb is one of the ingredients that I look forward to the most every spring and summer. It adds a nice tangy flavor to my strawberry rhubarb pie and rhubarb crumble bars, and it also makes amazing strawberry rhubarb jam.
My latest obsession is this Rhubarb Cake, which is an elegant way to showcase the beautiful red stalks of rhubarb.
Like my cherry almond cake, this recipe can be whipped up in just a few minutes, and it can incorporate a variety of fruits to change it up based on what you have on hand.
They’re great with just a dusting of powdered sugar, ice cream or a dollop of homemade whipped cream.
Dessert doesn’t get much simpler or delicious than this. 🙂

Recipe Ingredients
- All purpose flour. Sub with whole wheat white flour for added fiber.
- Almond flour. The almond flour adds flavor and a bit of heartiness that works very well in this cake. For best results, use super fine almond flour as it will produce a lighter crumb. Do not use almond meal as the cake will have a mealy, dense texture. Sub with the same amount of all purpose flour if you don’t have any on hand (the texture will vary slightly).
- Rhubarb. Fresh or frozen rhubarb may be used. If frozen, thaw it completely and blot it dry with paper towels. Reserve one stalk of rhubarb to make a design on top of the cake, or chop it and fold it into the cake batter. If you love rhubarb, be sure to my collection of rhubarb recipes for exciting new ways to use it.
- Butter. Softened butter is creamed with sugar to produce a super fluffy cake, and it adds great flavor. Cut it into small cubes and let stand at room temperature to soften it faster. See the recipe notes below to make this rhubarb cake dairy-free.
- Sugar. I used maple sugar in this recipe, but it will work with granulated sugar, coconut sugar or brown sugar as well.
- Eggs. Use room temperature large eggs. Place the eggs in a bowl of lukewarm water to bring to room temperature faster.
- Buttermilk. No buttermilk? Simply combine whatever type of dairy or non-dairy milk with a tablespoon of lemon juice or apple cider vinegar and stir. Let stand for 10 minutes to sour.
- Baking powder and baking soda. Baking power is essential for leavening. Baking soda reacts with the acid in the buttermilk, creating carbon dioxide and provides even more lift in the cake.
- Orange zest and vanilla extract. The orange zest and vanilla add a ton of flavor to the cake. You can change up this cake by adding a teaspoon of ground cinnamon or cardamom, or substitute the vanilla with almond extract.
- Powdered sugar. The powdered sugar is a completely optional garnish.
