The Only Rhubarb Bundt Cake Recipe You Will Ever Need
If you have a bundle of rhubarb sitting on your counter and no idea what to do with it, this is your answer. This Rhubarb Bundt Cake is everything a great spring and summer dessert should be: beautifully tall, sliceable, deeply buttery, and shot through with pockets of tart, jewel-bright rhubarb in every single bite. It is the kind of cake that disappears off the table before you have even finished pouring the coffee.
Rhubarb gets overlooked far too often. Most people reach for strawberries or blueberries when they want a fruit cake, but rhubarb has this incredible tartness that actually balances the sweetness of a cake batter in a way that other fruits simply cannot. The result is a cake that tastes complex and interesting rather than one-dimensional. Think of this as your go-to simple rhubarb cake recipe for everything from casual weekend baking to a proper celebration centerpiece.
Why This Recipe Works So Well
A great easy rhubarb cake lives or dies on a few key decisions, and this one gets all of them right.
Sour cream is the secret weapon. Cakes baked with sour cream have a tighter, more velvety crumb that holds up beautifully to the moisture that rhubarb naturally releases during baking. It also adds a gentle tang that echoes the rhubarb itself, making the whole cake taste more intentional and layered.
Fresh rhubarb folded in raw. Rather than cooking or macerating the rhubarb first, this recipe calls for folding it in straight from the cutting board. As the cake bakes, those pieces soften and melt into jammy little pockets while the surrounding crumb stays perfectly tender.
The Bundt format is ideal for this batter. The tall ring shape gives the rhubarb pieces somewhere to go without sinking to the bottom, and the large surface area means you get more of that gorgeous golden crust in every slice.
Chef's Tip: Do not skip greasing every single ridge of your Bundt pan. A stuck Bundt cake is heartbreaking. Use a pastry brush to really work softened butter or baking spray into every groove before flouring.
Choosing Your Rhubarb and Tools
For the best flavor, look for firm, deeply red stalks of fresh rhubarb at your farmers market or grocery store. The redder the stalk, the more vivid the color and the more pronounced the tartness will be. Thinner stalks tend to be more tender, while very thick stalks can be slightly stringy. Either works perfectly in this cake once chopped.
Having the right equipment genuinely changes the outcome here. A good quality 10-cup Bundt pan with well-defined ridges and a non-stick coating is the most important investment for this recipe, and a reliable stand mixer will make the creaming step effortless.
Tips for Baking This Vintage Rhubarb Cake
A few things to keep in mind before you start:
- Room temperature ingredients matter. Cold butter will not cream properly, and cold eggs can cause the batter to curdle. Pull everything out of the refrigerator about 45 minutes before you begin.
- Measure your flour correctly. Spoon it into your measuring cup and level it off rather than scooping directly from the bag. Scooping packs in excess flour and leads to a dry, dense crumb.
- Do not overmix once the flour goes in. Mix just until you no longer see dry streaks. Overmixing develops gluten and makes cakes tough.
- Test for doneness properly. Because Bundt cakes are thick, a regular toothpick might not reach the center. Use a long skewer or a thin cake tester.
Chef's Tip: If the top of the cake begins to look very dark before the interior is fully set, lay a loose sheet of aluminum foil over the top of the pan. This shields the surface without trapping steam.
Serving Suggestions and Variations
This quick rhubarb cake recipe is stunning served simply with a vanilla powdered sugar glaze, but it is also wonderful with a few easy variations:
- Strawberry Rhubarb: Swap half the rhubarb for diced fresh strawberries for a classic flavor pairing.
- Warm Spice Version: Add a pinch of ground ginger and cardamom alongside the cinnamon for a spicier, more aromatic crumb.
- Cream Cheese Glaze: Beat 2 ounces of softened cream cheese with the powdered sugar and milk for an ultra-rich, tangy topping that pairs beautifully with the tart rhubarb.
Serve slices at room temperature with a dollop of lightly whipped cream or a scoop of good vanilla ice cream. For brunch, a simple dusting of powdered sugar is all you need.

Rhubarb Bundt Cake
This stunning Rhubarb Bundt Cake is tender, buttery, and packed with bright, tart rhubarb in every bite. An easy rhubarb cake recipe that looks impressive and comes together with simple pantry staples.
Ingredients
- 2 1/2 cups all-purpose flour, spooned and leveled
- 1 1/2 tsp baking powder
- 1/2 tsp baking soda
- 1/2 tsp salt
- 1 tsp ground cinnamon
- 1/2 cups unsalted butter, softened to room temperature
- 1 1/2 cups granulated sugar
- 3 large eggs, room temperature
- 2 tsp vanilla extract, pure, not imitation
- 1 cup sour cream, full-fat, room temperature
- 2 1/2 cups fresh rhubarb, trimmed and cut into 0.5-inch pieces
- 1 cup powdered sugar, for glaze
- 2 tbsp whole milk, for glaze, plus more as needed
Instruction
Preheat your oven to 350 degrees F (175 degrees C). Generously grease and flour a 10-cup Bundt pan, making sure to coat every crevice. Set aside.
In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon until combined. Set aside.
In a large bowl using a hand mixer or stand mixer fitted with the paddle attachment, beat the softened butter and granulated sugar together on medium-high speed for 3 to 4 minutes until light, pale, and fluffy.
Add the eggs one at a time, beating well after each addition and scraping down the sides of the bowl as needed. Mix in the vanilla extract.
Reduce the mixer speed to low. Add the flour mixture in three additions, alternating with the sour cream in two additions, beginning and ending with the flour. Mix just until no dry streaks remain. Do not overmix.
Fold the chopped fresh rhubarb into the batter using a rubber spatula until evenly distributed.
Pour and spread the batter evenly into the prepared Bundt pan. Tap the pan gently on the counter two or three times to release any air bubbles.
Bake for 50 to 60 minutes, or until a long skewer or toothpick inserted into the thickest part of the cake comes out clean. If the top is browning too quickly after 40 minutes, tent loosely with foil.
Allow the cake to cool in the pan on a wire rack for exactly 15 minutes. Then carefully invert onto the rack and let it cool completely before glazing, at least 1 hour.
To make the glaze, whisk together the powdered sugar and milk in a small bowl until smooth and pourable. Add milk a teaspoon at a time to adjust thickness. Drizzle over the cooled cake, slice, and serve.

Notes
Storing and Making Ahead
One of the best things about this rhubarb cake recipe with fresh rhubarb is how well it keeps. The sour cream in the batter means the crumb stays moist for days, unlike leaner cakes that dry out quickly.
Store the finished cake covered at room temperature for up to 2 days, or transfer it to an airtight container in the refrigerator for up to 5 days. Many bakers actually prefer this cake on day two, when the rhubarb flavor has had time to settle deeper into the crumb.
To freeze, skip the glaze and wrap the fully cooled cake tightly in two layers of plastic wrap, then a layer of foil. It keeps beautifully in the freezer for up to 3 months. Thaw overnight at room temperature, then add fresh glaze before serving.
