Ingredients for old-fashioned norwegian rhubarb cake
Cardamom-spiced cake layers and tart rhubarb filling—just 13 ingredients for a dessert that tastes like Norwegian tradition.
| Ingredient | Amount | Notes |
|---|---|---|
| All-Purpose Flour 🌾 | 3 cups | Sifted for light texture |
| Granulated Sugar 🍚 | 1 ½ cups | White or light brown |
| Unsalted Butter 🧈 | 1 cup | Cold, cubed for creaming |
| Large Eggs 🥚 | 2 whole | Room temperature preferred |
| Ground Cardamom 🌿 | 1 ½ tsp | True Norwegian cardamom pods preferred |
| Baking Powder 🍞 | 1 ½ tsp | Aluminum-free for best rise |
| Salt 🧂 | ½ tsp | Fine sea salt preferred |
| Fresh Rhubarb 🍓 | 3 cups | Chopped into 1/2-inch pieces |
| Rhubarb Jam 🍯 | ½ cup | Homemade or quality store-bought |
| Lemon Zest 🍋 | 1 tbsp | From 1 large organic lemon |
| Powdered Sugar 🍚 | ¼ cup | For dusting final layers |
| Heavy Cream 🥛 | ½ cup | For optional glaze (optional) |
| Vanilla Extract 🍦 | 1 tsp | Pure Madagascar preferred |
The cardamom is non-negotiable here—Norwegian cardamom pods (whole or ground) give the most authentic flavor. If you can't find them, Eastern spice markets or specialty grocers like Whole Foods often carry them. Look for vibrant green pods that smell intensely aromatic when crushed. For rhubarb, farmers markets in spring are your best bet—bright pink stalks with crisp texture. If you're outside rhubarb season, substitute with tart apples (like Granny Smith) but reduce sugar in the filling by half. The butter should be cold when creamed—take it out of the fridge 10 minutes before starting.
No cardamom pods? Ground cardamom from Penzeys works perfectly, but avoid pre-mixed spice blends—they often contain cinnamon or cloves that disrupt the delicate balance. Running short on rhubarb? Cranberry sauce or boysenberry jam can mimic that tart-sweet contrast. The jam in the filling adds depth—Mott's or Bonne Maman are reliable brands. For the glaze, if you're feeling adventurous, swap the cream for aquavit-infused whipped cream (just add 1 tsp aquavit to the whipped cream). The vanilla extract? Pure Madagascar has the most complex flavor—worth the splurge for this recipe.
Store the cake layers in an airtight container between parchment paper for up to 3 days—they actually improve overnight. The rhubarb filling keeps for 5 days in the fridge, but assemble the cake within 2 days of baking for best texture. For make-ahead baking, prep the filling and freeze it in a jar for up to 3 months. The assembled cake freezes beautifully—just wrap tightly in plastic and thaw at room temperature before serving. Dust with powdered sugar right before serving to keep it looking fresh.
Why You'll Love This Recipe
- No Cardamom? No Problem: I’ll be real—this cake doesn’t need cardamom to shine, but that warm, citrusy pinch makes it taste like a cozy Norwegian bakery. Swap it for cinnamon or even a dash of vanilla if you’re out, and it’ll still be tender, buttery perfection.
- One-Bowl Wonder: Honestly, the only tools you’ll need are a mixing bowl and a whisk. Cream butter and sugar, toss in eggs, fold in dry ingredients—no food processor, no fancy techniques, just a cake that comes together faster than you can boil rhubarb.
- Rhubarb Magic: That tart, jammy rhubarb filling cuts through the richness of the cake like a cool breeze. I’ve made this with fresh or frozen rhubarb, and both work—just don’t skip the sugar in the filling, or you’ll regret it.
- Leftovers? Better: This cake stays moist for days, so I always bake two. Slice one for breakfast with coffee, pack the other for work, and by Thursday, you’ll still have slices that taste fresh. (Yes, even on a Tuesday night.)
Step-by-step instructions for Norwegian rhubarb cake
Here's how to create layers of spiced cake and tart rhubarb that capture Norway's rustic baking tradition.
Prepare the Rhubarb Filling
In a medium bowl, combine the 3 cups fresh rhubarb and 0.5 cup rhubarb jam. Stir in the 1 tablespoon lemon zest and let the mixture sit for 10 minutes at room temperature. This allows the flavors to meld and the rhubarb to soften slightly. The filling should be thick but spreadable—if it's too thick, add 1 teaspoon water to loosen it. The lemon zest brightens the tart rhubarb, balancing its natural acidity while enhancing its floral notes.
While the filling rests, preheat your oven to 350°F. Grease two 8-inch round cake pans and line the bottoms with parchment paper. A light coating of butter on the pans ensures easy release, while the parchment prevents sticking to the delicate cake layers. I always use round pans for this recipe—they create an elegant presentation while allowing even baking.
Create the Cardamom-Spiced Cake Batter
In a stand mixer fitted with the paddle attachment, beat the 1 cup unsalted butter and 1.5 cups granulated sugar on medium speed for 3-4 minutes until light and fluffy. The butter should be cold when you start—this creates air pockets that make the cake tender. Scrape down the sides of the bowl as needed to ensure even mixing.
Add the 2 whole large eggs, one at a time, mixing well after each addition. Then stir in the 1 teaspoon vanilla extract and 1.5 teaspoons ground cardamom. The cardamom is essential here—it gives the cake its signature Norwegian warmth. In a separate bowl, whisk together the 3 cups all-purpose flour, 1.5 teaspoons baking powder, and 0.5 teaspoon salt. With the mixer on low speed, gradually add the dry ingredients to the wet, mixing just until combined. Overmixing develops gluten, which can make the cake dense.
Assemble and Bake the Layers
Divide the batter evenly between the prepared cake pans. For the first layer, spread half of the batter into one pan and half of the rhubarb filling into the other. Top the rhubarb layer with the remaining batter. Use a spatula to smooth the tops—this ensures even baking and a clean finish. The layers should be about 1 inch thick each.
Bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean. Rotate the pans halfway through baking for even browning. The cake should be golden on top with a slightly domed center. As soon as it's done, remove from the oven and let cool in the pans for 10 minutes. This step is crucial—it prevents the layers from cracking when you transfer them to a wire rack to cool completely.
Add the Cream and Glaze
Once the cakes are completely cool, spread 0.5 cup heavy cream evenly between the layers. You can also use a simple glaze by mixing 0.25 cup powdered sugar with 1 tablespoon water or lemon juice until smooth, then drizzling it over the top layer. The cream adds a luxurious richness, while the glaze gives a professional finish. For extra flavor, brush the top with a little rhubarb jam before adding the glaze.
Let the cake sit at room temperature for at least 1 hour before slicing. This allows the layers to fully set and the flavors to develop. The finished cake should have moist, tender layers with a perfect balance of sweetness and tartness from the rhubarb. The cardamom's aromatic warmth lingers with every bite, making this a truly old-fashioned Norwegian treat.
Pro Tips For Making Old-Fashioned Norwegian Rhubarb Cake
- Cream Butter Slowly: I used to dump cold butter straight into the sugar and wonder why the texture turned grainy. Instead, soften the butter first—just until it yields to gentle pressure—and beat it with the sugar for a full 3 minutes. The butter should look fluffy and pale, not streaked. This isn’t just about aeration; it’s how you get that tender crumb Norwegian bakeries swear by.
- Sift That Cardamom: Cardamom is potent, and clumps in the batter will make your cake taste unevenly spiced. Sift it with the flour—yes, even if the package says "pre-ground." I learned this the hard way when one slice tasted like a spice cabinet and the next like nothing. A fine-mesh sieve does the trick, and don’t skip it.
- Don’t Overmix the Batter: Once you fold in the rhubarb (if using), stop mixing the second the flour disappears. Overworking the batter develops gluten, and your cake will turn out dense instead of light. Two gentle turns with a spatula is all it takes—this isn’t pancake batter. Trust me, your future self will notice the difference.
- Test for Doneness Early: The cake’s edges might look set, but the center can stay gummy if you pull it out too soon. After 40 minutes, slide a thin skewer into the middle—it should come out clean or with one moist crumb. If it’s wet, give it 5 more minutes. No guessing; this is how you avoid a sad, underbaked center.
Storing and reheating your old-fashioned norwegian rhubarb cake
Room-Temp Revival
If your rhubarb cake has spent time in the fridge, let it sit at room temperature for 30-45 minutes before reheating. This gradual warming prevents moisture buildup that can make the layers soggy. I place the cake on a wire rack over a baking sheet to catch any condensation.
For a quick test, slice a piece—if the layers feel firm and the rhubarb filling holds its shape, it's ready. 💡
Oven Refresh
Preheat your oven to 300°F and wrap the cake tightly in aluminum foil to retain moisture. Place it on a baking sheet and heat for 10-15 minutes, depending on size. The goal is to warm through without drying out—check at 10 minutes and adjust as needed.
The cardamom aroma will fill your kitchen, signaling it's ready to serve. For extra shine, brush the top with a little aquavit or lemon juice before reheating.
Microwave Method
For smaller slices, microwave reheating works well if done carefully. Place a single slice on a microwave-safe plate, cover loosely with a damp paper towel, and heat for 20-30 seconds on 50% power.
This gentle approach preserves the cake's texture while warming the filling. Repeat in 10-second intervals until heated through. The rhubarb filling should be warm but not runny—this keeps the traditional tartness intact. ❄️
Freezer Storage Tips
If you've frozen the cake, thaw it overnight in the fridge before reheating. Wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn. Once thawed, follow the room-temperature revival method above.
The cardamom and rhubarb flavors actually deepen after freezing, making this a great make-ahead option for special occasions. Just avoid thawing at room temperature—it can cause condensation and ruin the texture.
Filling Preservation
Save any leftover rhubarb filling by storing it in an airtight container in the fridge for up to 5 days. If it thickens, stir in 1 teaspoon water or lemon juice to restore its spreadable consistency.
For longer storage, freeze the filling in a jar with a tight lid, leaving 1 inch of headspace for expansion. Thaw in the fridge overnight before using—never microwave frozen rhubarb filling directly, as it can turn mushy. 🌱
Glaze Refresh
If the glaze looks dry after storage, simply whisk together 2 tablespoons powdered sugar with 1 teaspoon water or lemon juice and brush it over the top layer. For extra flavor, add ½ teaspoon ground cardamom to the glaze mixture.
This not only refreshes the appearance but also enhances the Norwegian spice profile. The glaze should be thin enough to drip slightly—this ensures even coverage without overwhelming the cake's delicate texture.

Frequently asked questions
Why does this recipe use cardamom instead of cinnamon?
Cardamom is the traditional Norwegian spice for this cake, offering a warm, floral aroma that pairs perfectly with rhubarb's tartness. Unlike cinnamon, which can overpower the delicate flavors, cardamom adds subtle complexity without competing. The recipe uses 1.5 teaspoons ground cardamom for authentic taste—avoid pre-mixed spice blends that often contain cinnamon or cloves.
Can I make this cake without fresh rhubarb?
Use 3 cups tart apples (like Granny Smith) instead, but reduce the sugar in the filling by half. For a jam alternative, try cranberry sauce or boysenberry jam—they mimic rhubarb's tangy-sweet balance. If using apples, cook them first to soften, then mix with 0.5 cup jam and 1 tbsp lemon zest as directed.
How do I prevent the rhubarb filling from leaking?
Ensure the rhubarb filling is thick but spreadable before assembly. If too runny, add 1 tsp cornstarch mixed with water to thicken. Also, chill the cake layers for 15 minutes after baking before adding filling—this helps set the structure. For extra stability, brush the first layer with a thin layer of apricot jam before adding filling.
What’s the best way to serve this cake?
Serve warm with a dusting of powdered sugar or a drizzle of aquavit-infused glaze for a Norwegian touch. Pair it with whipped cream or vanilla ice cream to balance the tart filling. For a rustic presentation, slice into wedges and arrange on a wooden board with fresh berries.
Can I make this cake in a single layer instead of two?
Yes! Use one 9-inch round pan and bake for 35-40 minutes at 350°F. Spread the batter evenly, then top with rhubarb filling before adding the second layer of batter. The baking time may increase slightly—check with a toothpick. This version works well for smaller gatherings or as a single-serving cake.
