Rhubarb Bundt Cake Recipe (Moist, Easy, and Bursting with Fresh Flavor)

The Rhubarb Bundt Cake You Will Make Every Spring

If you have ever stood in the garden staring at a pile of ruby-red rhubarb stalks wondering what on earth to bake next, this is the answer. This rhubarb bundt cake is everything a spring dessert should be: tender and moist with a fine, buttery crumb, a gentle tartness from fresh rhubarb tucked into every slice, and a simple vanilla glaze that makes it look like it came straight from a bakery window. It is honestly one of the most satisfying easy rhubarb cake recipes you will ever try.

Unlike a lot of rhubarb cake recipes that lean heavily on strawberries or extra spices to balance the tang, this one lets the rhubarb shine. A touch of cinnamon, a generous measure of vanilla, and a scoop of sour cream are all it takes to bring everything into perfect balance.

Why This Simple Rhubarb Cake Recipe Works So Well

This recipe borrows from the tradition of vintage rhubarb cake recipes that home bakers have passed down for generations, while adding a few modern tweaks that make it reliably foolproof.

Here is what makes this quick rhubarb cake recipe a keeper:

• Sour cream keeps the crumb incredibly moist for days, not just the first afternoon.
• Two sugars (granulated and brown) layer in sweetness and a light caramel depth that balances the tartness of the rhubarb beautifully.
• Fresh rhubarb pieces fold directly into the batter so every single bite has fruit in it.
• The bundt pan is more than aesthetic. Its shape promotes even baking all the way through, which matters a lot with a fruit-heavy batter.

Chef's Tip: Do not peel your rhubarb. The red skin adds gorgeous color to the finished cake and softens completely during baking.

Before we get into the recipe, it is worth saying that a quality bundt pan and a reliable stand mixer genuinely change the outcome here. A heavy, non-stick bundt pan releases the cake cleanly every time, and properly creamed butter is the foundation of that tender crumb.

Tips for Baking With Fresh Rhubarb

If this is your first time baking a rhubarb cake recipe with fresh rhubarb, here are a few things worth knowing before you start:

• Choose firm, crisp stalks. Limp rhubarb has excess water content that can affect the texture of your cake.
• Cut pieces small and even. Roughly half-inch pieces distribute evenly through the batter and soften into jammy little pockets without making the cake wet.
• Toss the rhubarb in a tablespoon of flour before folding it in. This light coating helps suspend the pieces throughout the batter rather than letting them sink.
• Rhubarb is tart by nature. This recipe is calibrated to balance that tartness with sweetness, so resist the urge to add extra sugar.

A note on frozen rhubarb: If fresh is not available, frozen works. Add it straight from the freezer without thawing to prevent extra moisture from loosening the batter.

How to Get a Perfect Release From Your Bundt Pan

The most nerve-wracking moment of any bundt cake is the unmolding. Here is how to make sure it goes smoothly every single time:

1. Grease the pan thoroughly with softened butter and a pastry brush, getting into every ridge.
2. Dust with flour and tap out the excess.
3. Cool the cake in the pan for exactly 15 minutes, not more. Too short and the cake is fragile; too long and steam causes it to stick.
4. Place a wire rack over the pan, flip confidently in one smooth motion, and lift the pan straight up.

This is one of those rhubarb recipes cake bakers return to year after year, and getting the unmolding right is a big part of why it feels so rewarding.

Ingredients

Units

USM

Scale

1x2x3x

• 2 1/2 cups all-purpose flour, spooned and leveled
• 1 tsp baking soda
• 1 tsp baking powder
• 1/2 tsp salt
• 1 tsp ground cinnamon
• 1/2 cup unsalted butter, softened to room temperature
• 1 cup granulated sugar
• 1/2 cup light brown sugar, packed
• 3 large eggs, room temperature
• 2 tsp pure vanilla extract
• 1 cup sour cream, full-fat, room temperature
• 2 1/2 cups fresh rhubarb, trimmed, cut into 0.5-inch pieces
• 1 cup powdered sugar, for the glaze
• 2 tbsp whole milk, for the glaze, add more as needed
• 1 tbsp unsalted butter, melted, for greasing the pan

Instruction

1

Preheat your oven to 350 degrees F (175 degrees C). Generously grease and flour a 10 to 12-cup bundt pan, making sure to coat every crevice. Set aside.

2

In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon. Set aside.

3

In a large bowl, beat the softened butter with the granulated sugar and brown sugar on medium-high speed for 3 to 4 minutes until the mixture is light, pale, and fluffy.

4

Add the eggs one at a time, beating well after each addition. Mix in the vanilla extract.

5

Reduce the mixer speed to low. Add the flour mixture in three additions, alternating with the sour cream, beginning and ending with the flour. Mix just until combined after each addition. Do not overmix.

6

Using a spatula, gently fold the chopped fresh rhubarb into the batter until evenly distributed.

7

Pour the batter into the prepared bundt pan and smooth the top with a spatula.

8

Bake for 50 to 58 minutes, or until a wooden skewer inserted into the thickest part comes out clean and the top is golden brown.

9

Allow the cake to cool in the pan on a wire rack for exactly 15 minutes, then invert onto the rack and allow it to cool completely before glazing.

10

To make the glaze, whisk together the powdered sugar and milk until smooth and pourable. Drizzle generously over the completely cooled cake and allow it to set for 10 minutes before slicing.

Equipment

• 10 to 12-cup bundt pan
• Stand mixer or hand mixer
• Large mixing bowl
• Medium mixing bowl
• Rubber spatula
• Wire cooling rack
• Wooden skewer or toothpick
• Whisk

Notes

Store leftover cake covered at room temperature for up to 2 days, or in the refrigerator for up to 5 days. The cake actually tastes even better on day two as the flavors deepen. To freeze, wrap individual slices tightly in plastic wrap and store in a freezer-safe bag for up to 3 months. Thaw at room temperature before serving. Do not glaze slices you plan to freeze. For a make-ahead option, bake the cake a day in advance and glaze just before serving.

Serving, Storing, and Variations

Serving suggestions: This cake is wonderful at room temperature with the vanilla glaze and a cup of strong coffee or Earl Grey tea. For something more indulgent, serve warm slices with a scoop of vanilla ice cream or a dollop of lightly whipped cream.

Variations to try:

• Add the zest of one orange to the batter for a bright citrus note that pairs brilliantly with rhubarb.
• Swap the vanilla glaze for a cream cheese glaze by whisking 2 ounces of softened cream cheese with the powdered sugar and milk.
• Stir in 0.5 cup of chopped toasted walnuts or pecans for texture.

Storage: Cover and store at room temperature for up to 2 days, or refrigerate for up to 5 days. The flavor genuinely deepens overnight, making this one of those rare cakes that is better the next day. Slices also freeze beautifully for up to 3 months.
