Ingredients You’ll Need
Every ingredient in this cake plays an essential role, from the oats and flour that create the perfect crumbly texture to the rhubarb that lends a fresh burst of color and tanginess. These straightforward ingredients come together seamlessly to deliver a balance of richness and brightness that makes this cake so special.
- 500 grams fresh rhubarb: Sliced into ½ inch pieces, the star of the compote with its vibrant tartness.
- 50 grams superfine/caster sugar: Sweetens the rhubarb compote gently without overpowering its natural flavor.
- 1 teaspoon vanilla extract: Adds a warm, fragrant undertone to the compote’s brightness.
- 135 grams rolled oats: Pulsed to a finer texture to contribute a hearty, rustic crumb.
- 240 grams plain flour: Provides structure while keeping the crumb tender.
- 100 grams superfine/caster sugar: Balances moisture and sweetness in the cake base.
- 50 grams brown sugar: Gives a subtle caramel note and depth to the crumb.
- 1 teaspoon ground cardamom: Adds a hint of warm spice that beautifully complements the rhubarb.
- ¾ teaspoon baking soda: Helps the crumb rise perfectly and remain light but sturdy.
- 225 grams softened butter: Cubed butter creates that signature rich, clumpy texture in the crumb.
- 45 grams (1 medium) egg at room temperature: Binds everything into a luscious, wet crumble mixture.
How to Make Icelandic Happy Marriage Cake with Rhubarb Compote Recipe
Step 1: Prepare the Rhubarb Compote
Begin by lining an 8-inch round cake tin with parchment paper to keep your cake from sticking and make cleanup easier. Then, toss the rhubarb slices, sugar, and vanilla extract into a medium saucepan over medium heat. Put a lid on and stir occasionally. Patience here is key; cooking until the rhubarb softens while retaining a bit of shape, about 15 minutes, achieves a compote that’s juicy yet not mushy. Let it cool fully, as this juicy layer will bring freshness and moisture that contrasts beautifully with the crumbly cake.
Step 2: Make the Cake Crumb
Preheat your oven to 200 degrees Celsius (or 400 Fahrenheit). Pulse the rolled oats in a blender or food processor to break them down slightly but still keep some texture — think coarsely ground rather than powder fine. Combine the oats, flour, caster sugar, brown sugar, ground cardamom, and baking soda in a bowl, stirring well to marry the dry ingredients evenly. Next, toss in the softened, cubed butter. Using your fingers or a pastry cutter, mix until it resembles a clumpy crumble — this clumpiness is key to the cake’s signature texture. Add in the egg and stir gently on low speed or by hand until all dry patches disappear and the mixture is moist but still crumbly.
Step 3: Assemble and Bake
Take two thirds of the crumb mixture and press it firmly into the bottom and up the sides of your prepared cake tin, creating a sturdy base and edge to hold the filling. Spoon the cooled rhubarb compote evenly over this crust, making sure to leave some space around the edges for sealing. Scatter the remaining cake crumb over the compote in uneven clumps — this rustic style topping will bake golden and crisp. Pop your creation into the oven and bake for around 25 minutes until the top is a warm gold and the cake smells heavenly. Once out of the oven, allow it to cool completely before gently removing it from the tin. Slicing and serving with a dollop of whipped cream elevates this dessert to pure joy.

Garnishes
This cake loves company. A light dusting of powdered sugar or a generous spoonful of softly whipped cream brings an extra touch of indulgence. For a bright contrast, fresh mint leaves or a few extra rhubarb ribbons on the side add charm and a little freshness that wakes up the palate.
Side Dishes
Pairing the cake with a scoop of vanilla ice cream or a small bowl of lightly sweetened Greek yogurt can turn this simple treat into a full dessert experience. If you want to keep it cozy, a hot cup of herbal tea or rich coffee perfectly complements the cardamom’s warming spice and the rhubarb’s tang.

Layer slices with a smear of cream cheese frosting for a fusion twist, or sandwich the cake between light sponge layers for an elegant, layered dessert. The rustic charm of this cake also shines when presented in a glass trifle, layered with cream and rhubarb compote for a visually stunning treat.
Make Ahead and Storage
Storing Leftovers
This cake keeps wonderfully in an airtight container at room temperature for up to three days. The crumb topping may soften slightly, but the flavors only deepen, making each slice a little better the next day.
Freezing
To enjoy this cake even weeks later, wrap slices individually in plastic wrap and tuck them inside a freezer-safe container. Frozen, the Icelandic Happy Marriage Cake with Rhubarb Compote Recipe will hold its flavor and texture for up to two months.
Reheating
When you’re ready to indulge again, thaw the slices overnight in the refrigerator and warm gently in a low oven or microwave just until cozy and fragrant. A little cream or ice cream on top finishes it off perfectly.
FAQs
Can I use frozen rhubarb instead of fresh?
Absolutely! Frozen rhubarb works well for the compote and can make this recipe even more convenient year-round. Just thaw and drain any excess liquid before cooking to avoid a watery filling.
Is the cardamom essential in this recipe?
Cardamom adds a unique, warming depth that really lifts the cake, but if you don’t have it, cinnamon or ginger can be great substitutes, bringing their own cozy character to the crumb.
Can I make this cake gluten-free?
Yes, by swapping the plain flour for a gluten-free blend that measures cup-for-cup, and ensuring your oats are certified gluten-free, you can enjoy this lovely cake without gluten worries.
How do I know when the cake is fully baked?
The top should be a rich golden brown and the edges pulling slightly away from the tin. A toothpick inserted into the crumb topping should come out with only moist crumbs attached.
What’s the best way to serve leftover cake?
Leftovers taste fantastic slightly warmed with a touch of whipped cream or yogurt. The slight warmth releases all the wonderful aromas, making it feel freshly baked even the next day.

Ingredients
Rhubarb Compote
- 500 grams (1 pound) fresh rhubarb, sliced into ½ inch thick pieces

- 1 teaspoon vanilla extract
Cake Crumb
- 135 grams (1 ½ cups) rolled oats

- 50 grams (¼ cup) brown sugar
- 1 teaspoon ground cardamom
- 4 grams (¾ teaspoon) baking soda
- 225 grams (7.93 ounces) butter, softened and cubed
- 45 grams (1 medium) egg, room temperature
Instructions
- Prepare Rhubarb Compote: Line a 20 cm (8 inch) round cake tin with parchment paper and set aside. In a medium saucepan over medium heat, combine the rhubarb, superfine sugar, and vanilla extract. Cover with a lid and cook for about 15 minutes, stirring intermittently to ensure the rhubarb softens evenly while retaining some shape. Remove the compote from heat and allow it to cool completely.
- Make Cake Crumb Base: Preheat your oven to 200°C (400°F). Place the rolled oats into a blender or food processor and pulse until they become slightly finer but not to a powder. In a medium bowl, combine the pulsed oats, plain flour, superfine sugar, brown sugar, ground cardamom, and baking soda, mixing them thoroughly.
- Incorporate Butter and Egg: Add the softened, cubed butter to the dry mixture and cut it in using your fingers or a pastry cutter until the mixture resembles a clumpy crumble. Next, add the egg and gently combine on low speed or by hand until the mixture is evenly moistened and forms a wet crumble without any dry bits remaining.
- Assemble Base and Layer: Spoon two-thirds of this dough mixture into the prepared cake tin, pressing it firmly and evenly over the base and slightly up the sides of the tin to form a crust layer.
- Add Rhubarb Layer: Spread the cooled rhubarb compote evenly over the base crust, ensuring full coverage.
- Top with Remaining Crust: Crumble the remaining dough unevenly over the rhubarb compote to create a rustic crumb topping.
- Bake the Cake: Place the assembled cake in the preheated oven and bake for approximately 25 minutes or until the topping turns golden brown.
- Cool and Serve: Remove the cake from the oven and allow it to cool in the tin before carefully removing it. Slice the cake and serve warm or at room temperature, optionally accompanied by a dollop of whipped cream for added richness. Enjoy!
Notes
- Use fresh rhubarb for the best tart flavor; frozen rhubarb might become too watery.

- This cake can be stored covered at room temperature for up to 2 days or refrigerated for up to 4 days.
- For extra flavor, consider adding a pinch of cinnamon or nutmeg to the crumb topping.
- Serve with whipped cream or vanilla ice cream for a delightful contrast.
