I used to be the person who showed up to gatherings with store-bought dessert because baking intimidated me. Then I made this rhubarb raspberry marble cake completely by accident — I had rhubarb from my neighbor’s garden that needed using, some raspberries going soft in the fridge, and about two hours before everyone arrived. It came out of the bundt pan looking absolutely stunning: those pink-red swirls through golden cake, dusted with powdered sugar, and I stood in my kitchen genuinely proud of myself. Then I tasted it. Then I made it again the following weekend just because I wanted to. This rhubarb cake recipe is the one I bring everywhere now, and the first thing people ask when they see it is “did you make that yourself?”
What Makes This So Special
Here’s the thing about a rhubarb raspberry marble cake — the swirl isn’t just decorative. You cook the rhubarb and raspberries down into a thick, concentrated compote first, then swirl it through the vanilla bundt cake batter before baking. As it bakes, the compote steams gently inside the cake, creating pockets of jammy, tart fruit flavor suspended in tender, buttery crumb. The rhubarb brings a sharp, almost floral tartness that raspberries alone can’t quite achieve, and together they make a fruit swirl that tastes like the filling of the best possible jam pastry, baked right into the cake. This easy marble bundt cake is the definition of impressive with a surprisingly manageable effort — one bowl batter, one compote step, one beautiful result.
What You’ll Need (And My Shopping Tips)
Fresh rhubarb stalks should be firm and crisp — avoid any that are limp or fibrous looking. The redder the stalk, the more vibrant your swirl will be (though green rhubarb tastes identical, it just gives a more muted color in the cake). Frozen rhubarb also works beautifully — no need to thaw, just cook it a few minutes longer in the compote step. I learned this the one winter I desperately wanted this cake in February, and it honestly tasted just as good.
For raspberries, fresh or frozen both work. The raspberries are mostly there for color intensity and a gentle sweetness that softens the rhubarb’s sharpness — frozen work great here and they’re less expensive.
For the rhubarb raspberry compote:
- 1½ cups fresh or frozen rhubarb, chopped into ½-inch pieces
- 1 cup fresh or frozen raspberries
- 3 tablespoons granulated sugar
- 1 teaspoon lemon juice
For the cake batter:
- 2 cups all-purpose flour
- 1½ teaspoons baking powder
- ½ teaspoon baking soda
- ¼ teaspoon salt
- ¾ cup (1½ sticks) unsalted butter, softened to room temperature
- 1¼ cups granulated sugar
- 3 large eggs, room temperature
- 1 teaspoon vanilla extract
- 1 cup full-fat plain yogurt or sour cream (this is the secret to the tender crumb — don’t substitute with low-fat)
- Powdered sugar for dusting
Let’s Make This Together
Start with the compote. Combine the rhubarb, raspberries, sugar, and lemon juice in a small saucepan over medium heat. Stir occasionally for 8-10 minutes until the fruit breaks down and the mixture thickens to a jammy consistency — it should hold its shape briefly on a spoon before slowly running. Set it aside to cool completely. This is the step I used to rush, and adding warm compote to the batter makes it sink rather than swirl. Let it cool all the way.
Preheat your oven to 350°F. Grease your bundt pan thoroughly — and I mean every ridge, every crevice. A bundt pan that isn’t properly greased is a broken cake guaranteed. I use softened butter and a pastry brush, then dust with flour. This step has saved my sanity more times than I can count.
For the batter: beat the softened butter and sugar together until pale and fluffy, about 3-4 minutes. Don’t be me — I used to rush this step and end up with a dense cake. Proper creaming matters here. Add eggs one at a time, beating after each. Mix in the vanilla.
In a separate bowl, whisk flour, baking powder, baking soda, and salt. Add half the flour mixture to the butter mixture, then the yogurt, then the remaining flour. Mix just until combined — overmixing is what makes a tough cake. Some small lumps are fine.
Spoon about two-thirds of the batter into the prepared bundt pan. Dollop half the cooled compote over it in spoonfuls, then swirl gently with a butter knife or skewer — 4-5 slow figure-eight motions. Add the remaining batter, then the rest of the compote, and swirl again. You want visible swirls, not a completely mixed batter.
Bake for 45-55 minutes until a toothpick inserted in the thickest part comes out with just a few moist crumbs. Let it cool in the pan for exactly 15 minutes — not less, not more — before inverting onto a wire rack. Dust with powdered sugar once fully cooled.
If you love fruit-forward baking like this rhubarb raspberry cake, our Crumble Recipe uses similar fruit combinations in a completely different form — equally impressive and even simpler to put together.
When Things Go Sideways (And They Will)
Cake stuck to the bundt pan? Every bundt disaster comes down to not greasing thoroughly enough. Every ridge needs butter and flour — bundt pans have more surface area than they look. Next time, grease twice if you’re not sure. If it’s already stuck, run a thin offset spatula gently around every edge before trying to invert again.
Compote sank to the bottom instead of swirling? Either the compote was too warm when added, or the batter was too thin. Make sure the compote is fully cooled and room temperature, and don’t over-thin your batter with extra yogurt.
Cake dense and gummy inside? Two likely causes: the butter and sugar weren’t properly creamed (this takes real time — the mixture should be visibly pale and almost white), or the cake was underbaked. Every oven has its own personality, and a 45-minute estimate is a starting point, not a finish line. Trust the toothpick over the timer.

Ways to Mix It Up
Summer Strawberry Rhubarb Marble Cake: swap the raspberries for an equal amount of hulled and chopped strawberries. Classic pairing, gorgeous pink color, slightly sweeter overall.
When I’m making it for a special occasion, I’ll drizzle a simple lemon glaze (powdered sugar + lemon juice) over the top instead of the powdered sugar dusting. Lemon Glazed Rhubarb Raspberry Cake — the tartness of the lemon amplifies the rhubarb flavor beautifully.
For a loaf cake version, use a 9×5 inch loaf pan and reduce baking time to 55-65 minutes. Same swirl technique, slightly more casual presentation — perfect for gifting or coffee mornings.
Dairy-free version: replace the butter with coconut oil and the yogurt with full-fat coconut yogurt. The flavor is slightly different but still excellent, and the rhubarb swirl is just as beautiful.

Why This Works So Well
Rhubarb has been used in European baking since the 18th century, when sugar became affordable enough to tame its intense natural tartness. The key to using rhubarb in a cake — rather than a pie or crumble — is cooking it down to a concentrated compote first. Raw rhubarb contains too much water, which would make the batter wet and the cake gummy. By reducing it to a thick jam-like consistency, you concentrate the flavor and remove the excess moisture, leaving behind intensely tart fruit flavor in a form that swirls beautifully through batter without disrupting the crumb structure. The yogurt in the cake batter serves a complementary purpose — its acidity activates the baking soda for a tender lift, and its fat content creates a moist, fine crumb that can hold up to the weight of fruit swirls without collapsing.
Questions I Always Get
Can I make this rhubarb raspberry marble cake ahead of time? Yes — it’s actually better the next day once the flavors have settled and the crumb has relaxed. Bake it the day before, cool completely, dust with powdered sugar before serving. It keeps at room temperature under a cake dome for 2 days, or in the fridge for 4.
Can I use frozen rhubarb for this rhubarb cake recipe? Yes, and it works beautifully. No need to thaw — just add it frozen directly to the saucepan for the compote and cook a few minutes longer. The flavor is identical to fresh.
Do I need a bundt pan specifically? A regular 9-inch round cake pan works — reduce baking time to 35-40 minutes and check with a toothpick. You lose the dramatic bundt shape but the marble swirl is still gorgeous when you cut into it. A tube pan also works very well.
Why did my swirls disappear during baking? Too much swirling is actually the culprit — it blends the compote completely into the batter instead of keeping distinct streaks. Use only 4-5 slow figure-eight motions. Less swirling gives you more dramatic visible swirls in the finished cake, which seems counterintuitive but is completely true.
Can I use other fruit in this marble bundt cake? Yes — blackberries or blueberries work beautifully in place of raspberries. Strawberry is excellent too. The fruit just needs to be cookable into a thick compote — watery fruit like watermelon won’t work.
How do I store this rhubarb marble cake? Room temperature under a cake dome for 2 days. Refrigerator for up to 4 days — bring to room temperature before serving as the cold firms up the crumb. You can also freeze individual slices wrapped in plastic for up to 2 months.
Is this cake beginner-friendly? Yes — the batter is a straightforward one-bowl creamed butter cake, which is one of the most forgiving methods in baking. The compote step is just 10 minutes of stirring. The only real skill required is not rushing the bundt pan greasing.
Can I make this as muffins? Yes — fill a greased muffin tin ⅔ full, add a teaspoon of compote in the center of each, and swirl gently. Bake at 350°F for 20-22 minutes. Makes about 16 rhubarb raspberry muffins — great for meal prep or a school bake sale.

Recipe Card
Rhubarb Raspberry Marble Cake
A tender vanilla bundt cake swirled with tart rhubarb raspberry compote — a stunning homemade marble cake that’s easier than it looks and better than it sounds.
Prep Time: 25 minutes | Cook Time: 55 minutes | Total Time: 1 hour 20 minutes | Servings: 12
Ingredients:
Rhubarb Raspberry Compote:
- 1½ cups rhubarb, chopped into ½-inch pieces (fresh or frozen)
- 1 cup raspberries (fresh or frozen)
- 3 tablespoons granulated sugar
- 1 teaspoon lemon juice

Notes:
- Greasing the bundt pan is the single most important step — do it twice if you’re unsure. Every ridge needs attention.
- The compote must be fully cooled before swirling into the batter or it will sink rather than marble.
- Only 4-5 swirling motions — over-swirling blends the compote in completely and loses the marble effect.
Storage Tips:
- Room temperature under a cake dome: 2 days
- Refrigerator: up to 4 days — bring to room temperature before serving
- Freeze individual slices wrapped in plastic: up to 2 months
- Dust with fresh powdered sugar right before serving if storing overnight (it absorbs)
Serving Suggestions:
- Dusted with powdered sugar as a standalone show-stopping dessert
- With a dollop of lightly whipped cream or crème fraîche alongside
- With a scoop of vanilla ice cream for a warm-weather dessert
- As a breakfast cake with morning coffee — it’s not too sweet
Mix It Up:
Summer Strawberry Rhubarb Marble Cake: Replace raspberries with chopped strawberries for a classic pairing. Lemon Glazed Version: Drizzle with lemon glaze (1 cup powdered sugar + 2 tbsp lemon juice) instead of dusting with sugar. Loaf Cake Version: Bake in a 9×5 loaf pan at 350°F for 55-65 minutes — perfect for gifting. Rhubarb Raspberry Muffins: Fill muffin tins ⅔ full, add compote center, swirl, bake 20-22 minutes.
What Makes This Recipe Special:
Rhubarb must be cooked to a thick compote before being swirled into cake batter — its high water content would otherwise make the surrounding crumb wet and gummy. By reducing it to a jam-like consistency first, you concentrate the flavor while removing excess moisture, leaving behind intensely tart fruit in a form that creates clean, dramatic swirls without disrupting the cake’s structure. The yogurt in the batter serves a complementary purpose: its acidity activates the baking soda for a tender rise, while its fat content produces the fine, moist crumb that makes this marble bundt cake so satisfying to eat.
