How to Make Rose Rhubarb Layer Cake
-
Prepare Rhubarb Curd:
Start by washing and cutting the rhubarb into smaller pieces. Process the rhubarb into a fine pulp, then strain it to extract the juice. In a saucepan, combine the juice with eggs, sugar, and cornflour; cook over low heat, stirring continuously until thickened, about 10-15 minutes. Cool and chill for several hours or overnight for the best flavor. -
Bake the Cake Layers:
Preheat your oven to 350°F (175°C) and line 3 cake pans with parchment paper. In a mixing bowl, beat the eggs, sugar, and vanilla until pale and tripled in volume, roughly 5 minutes. Gently fold in the flour until just combined. Divide the batter among the prepared pans and bake for 20-25 minutes, or until golden brown and a toothpick comes out clean. Let them cool completely on wire racks. -
Make the Syrup:
In a small bowl, mix together the simple syrup with elderflower liqueur and a couple of drops of rose water. Set this floral syrup aside to infuse while you prepare the frosting. -
Prepare Mascarpone Cream:
In a chilled mixing bowl, whip the mascarpone for just a few seconds until creamy. Gradually add the whipped cream, icing sugar, and the remaining rose water, whipping until thick and smooth. Be careful not to overwhip! -
Assemble the Cake:
Once cooled, soak each cake layer lightly with the floral syrup. Pipe a border of mascarpone around the edge of the first layer to hold in the rhubarb curd, then fill the center with some curd. Repeat for the other layers before applying a crumb coat of mascarpone around the entire cake and chilling for about 30 minutes. -
Decorate:
After chilling, frost the entire cake with the remaining mascarpone cream. Adorn your creation with sprigs of lemon thyme, pink flowers, and dried rose petals for a stunning finish.
Optional: Serve with fresh berries or a dollop of whipped cream for extra indulgence.

Expert Tips for Rose Rhubarb Layer Cake
-
Room Temperature Eggs: Ensure your eggs are at room temperature for the cake; this step promotes better volume and texture when whipped.
-
Don’t Overmix: When folding flour into the egg mixture, be gentle. Overmixing can lead to dense sponge layers, ruining the cake’s fluffiness.
-
Thicken the Curd Properly: Cook the rhubarb curd until it thickens significantly, or it won’t set properly once cooled. Patience is key for the perfect consistency!
-
Moisture is Key: Soak each cake layer with syrup generously to lock in moisture, ensuring that every bite is soft and delectable.
-
Chill Before Frosting: Allow the crumb coat to chill; this helps create a smooth base for the final frosting and prevents crumbs from mixing into your mascarpone layer.
-
Creative Decorations: Feel free to personalize your decor! Add edible flowers or citrus slices for a unique and beautiful presentation to impress your guests.

Rose Rhubarb Layer Cake Recipe FAQs
What is the best way to select ripe rhubarb?
Absolutely! Look for rhubarb with firm, crisp stalks that are vibrant in color, usually a beautiful pink or green. Avoid any with dark spots all over or that feel soft or wilted, as these indicate over-ripeness or spoilage.
How should I store the Rose Rhubarb Layer Cake?
I recommend covering the cake with plastic wrap or placing it in an airtight container. You can store it in the refrigerator for up to 3 days. If you want to enjoy it later, frosting and all, you can freeze the cake layers separately, wrapping them well in plastic wrap and aluminum foil for up to 2 months.
Can I freeze the Rose Rhubarb Layer Cake?
Yes! For freezing, I suggest letting the frosted cake chill in the refrigerator for about 30 minutes before carefully wrapping it in plastic wrap, followed by aluminum foil. This step protects it from freezer burn and can preserve its flavor. Once ready to serve, allow it to thaw in the fridge overnight before bringing it to room temperature.
What should I do if my rhubarb curd is too runny?
Very! If your rhubarb curd doesn’t set as expected, you can cook it longer while stirring continuously on low heat to help thicken it. Another method is to prepare a slurry by mixing a tablespoon of cornflour with a bit of cold water, then add it to the warm curd mixture and heat until thickened, stirring constantly.
Is it possible to make a dairy-free version of the frosting?
For sure! You can use whipped coconut cream instead of mascarpone for a delicious, dairy-free alternative. Just whip the coconut cream until it reaches a fluffy texture, then sugar and flavor it with the same ingredients for a light and fragrant topping.
Are there any dietary concerns with this recipe?
Absolutely! This recipe contains eggs and dairy, making it unsuitable for vegans or those with egg or dairy allergies. For a vegan version, substitute eggs with a flaxseed meal mix (1 tablespoon of flaxseed meal + 3 tablespoons of water per egg) and use plant-based cream for the frosting. Make sure to opt for dairy-free butter and suitable sugar alternatives if needed.
