The beauty of this Romanian Walnut Buttercream Cake Recipe lies in its simplicity and the quality of each ingredient. Every component plays a vital role, from the eggs that make the sponge airy to the finely ground walnuts that infuse every layer with a toasty richness.
- 6 large eggs, separated: Egg yolks add richness while whisked whites bring essential lightness to the cake.
- 1 cup granulated sugar: Sweetens the batter and stabilizes the egg whites for that perfect rise.

- 3/4 cup all-purpose flour: The structure that holds the soft cake together without weighing it down.
- 1 teaspoon baking powder: Ensures the cake rises beautifully with a tender crumb.
- 1/4 teaspoon salt: Balances sweetness and intensifies flavors.
- 1 teaspoon vanilla extract: A warm note that complements the walnuts effortlessly.

- 1 cup powdered sugar: Sweetens the buttercream while making it silky and spreadable.
- 1/2 cup finely ground walnuts for buttercream: Adds texture and walnut flavor for the frosting.

How to Make Romanian Walnut Buttercream Cake Recipe
Step 1: Prep and Mix the Batter
Begin by preheating your oven to 350°F and preparing an 8-inch round pan by greasing and lining it with parchment paper for a smooth release. In a large bowl, beat the egg yolks with half the granulated sugar until they become pale and thick—this is where the cake’s rich base starts to form. Stir in the vanilla extract along with the finely ground walnuts, which bring that signature nutty character. Separately, whisk together the flour, baking powder, and salt, then gently fold this dry mixture into the yolk blend, making sure not to deflate the air you worked so hard to incorporate.
Step 2: Whip the Egg Whites and Fold
Using clean bowls and beaters, whip the egg whites until they form soft peaks. Gradually add the remaining sugar as you continue beating until stiff peaks appear. This step is crucial for lightening the batter, giving the cake its tender crumb and slight lift. Carefully fold the egg whites into the yolk mixture in batches, maintaining as much air as possible. This delicate folding makes all the difference for a light yet rich texture in the final cake.
Step 3: Bake the Cake
Pour the airy batter into the prepared pan, smoothing the top gently with a spatula. Bake for 30 to 35 minutes, until a toothpick inserted into the center comes out clean and the cake is golden. It’s important to let the cake cool completely in the pan before removing it; this helps preserve the delicate structure so it won’t crumble when you layer it.
Step 4: Prepare the Walnut Buttercream
To craft the decadent buttercream, begin by beating the softened butter until light and creamy. Gradually add the powdered sugar, mixing thoroughly to achieve a smooth consistency. Stir in the finely ground walnuts and cocoa powder for a wonderful depth of flavor that complements the walnut sponge perfectly. Add milk a tablespoon at a time, just until the buttercream reaches a spreadable texture—soft but stable enough to hold the layers together.
Step 5: Assemble the Cake
Once the cake is cool, carefully slice it horizontally into two even layers. Spread a generous amount of buttercream on the bottom layer, then place the top layer back on. Use the remaining buttercream to frost the top and sides evenly, creating a beautiful walnut-coated masterpiece. For the cleanest slices, refrigerate the assembled cake for at least 30 minutes before cutting.
How to Serve Romanian Walnut Buttercream Cake Recipe
Garnishes
This cake is stunning on its own, but a few simple touches can elevate the presentation. Sprinkle extra chopped or finely ground toasted walnuts over the top to add a rustic crunch. A light dusting of cocoa powder or a drizzle of dark chocolate can create visual contrast and deepen the chocolatey notes.
Side Dishes
Pairing this cake with a scoop of vanilla bean ice cream or a dollop of freshly whipped cream balances its rich nuttiness nicely. For a refreshing twist, serve alongside a crisp cup of herbal tea or freshly brewed coffee, which cuts through the richness and complements the cake’s flavor profile beautifully.
Creative Ways to Present
For a festive occasion, try layering the cake in mini springform pans to create individual servings that feel extra special. Another fun idea is to add a raspberry or cherry compote drizzle for a tart contrast. Presentation-wise, placing it on a rustic wooden board or a delicate cake stand immediately invites guests to dig in and savor every bite.
Make Ahead and Storage
Storing Leftovers
After enjoying your Romanian Walnut Buttercream Cake Recipe, wrap leftovers tightly with plastic wrap or place them in an airtight container. Store in the refrigerator to keep the buttercream fresh and maintain the cake’s moist texture. Properly stored, it will stay delicious for up to 3 days.
Freezing
If you want to save some for later, this cake freezes quite well. Wrap the entire cake or individual slices in plastic wrap and then foil to protect against freezer burn. When frozen, it’ll keep for up to 2 months without losing flavor. Thaw in the refrigerator overnight before serving to retain texture and taste.
Reheating
This cake is best enjoyed chilled or at room temperature, so reheating isn’t usually necessary. However, if you prefer a warmer slice, allow it to come to room temperature first and then gently warm a single slice in a microwave for about 10 seconds. This softens the buttercream slightly and enhances its flavors without melting the frosting completely.
FAQs
Can I use other nuts instead of walnuts?
Absolutely! While walnuts are traditional and provide the perfect flavor, you can experiment with pecans or hazelnuts. Just make sure to finely grind them and consider lightly toasting for the best taste.
Is this cake gluten-free?
The classic recipe uses all-purpose flour, which contains gluten. However, you could substitute with a gluten-free baking blend, though texture might vary slightly. Make sure your baking powder is gluten-free too.
How long does the cake take to bake?
The cake usually requires 30 to 35 minutes at 350°F. You’ll know it’s done when a toothpick inserted into the center comes out clean and the top is a lovely golden color.
Can I make the buttercream vegan?
Traditional buttercream relies on butter, but you can try a vegan butter substitute and powdered sugar to recreate the texture. Keep in mind, the flavor will be a bit different but still delicious.
What’s the best way to get clean slices when serving?
Chilling the cake for about 30 minutes after assembly firms up the buttercream, making slicing cleaner and easier. Using a hot, clean knife wiped between cuts also helps achieve perfect slices.
Final Thoughts
Making the Romanian Walnut Buttercream Cake Recipe is like inviting a little piece of Romanian tradition into your kitchen, creating a dessert that’s both comforting and impressive. The way the nutty sponge and creamy frosting melt together is truly unforgettable. I hope this recipe becomes one of your favorites to bake and share, bringing joy with every rich, velvety bite.

- 3/4 cup all-purpose flour
- 1 teaspoon baking powder
- 1/4 teaspoon salt
- 1 teaspoon vanilla extract
Buttercream
- 1/2 cup unsalted butter, softened
- 1 cup powdered sugar
- 1/2 cup finely ground walnuts
- 1 tablespoon cocoa powder
- 1 to 2 tablespoons milk, as needed
Instructions
- Prepare the Oven and Pan: Preheat your oven to 350°F (175°C). Grease and line an 8-inch round cake pan with parchment paper to ensure easy removal after baking.
- Make the Yolk Mixture: In a large mixing bowl, beat the egg yolks with half of the granulated sugar until the mixture is pale and thick, indicating the sugar has dissolved and the eggs have aerated. Stir in the vanilla extract and the finely ground walnuts to incorporate flavor and texture.
- Combine Dry Ingredients: In a separate bowl, whisk together the all-purpose flour, baking powder, and salt. Gently fold these dry ingredients into the yolk and walnut mixture, ensuring not to deflate the air incorporated into the egg yolks.
- Whip the Egg Whites: In a clean bowl, beat the egg whites until they form soft peaks. Gradually add the remaining granulated sugar while continuing to beat until stiff peaks form, which will add lightness to the batter.
- Incorporate Egg Whites: Carefully fold the whipped egg whites into the batter in batches. This delicate folding keeps the batter airy, contributing to a light sponge texture in the cake.
- Bake the Cake: Pour the finished batter into the prepared cake pan. Bake for 30 to 35 minutes or until a toothpick inserted in the center comes out clean. Once baked, allow the cake to cool completely in the pan before removing it.
- Prepare the Buttercream: Beat the softened butter in a mixing bowl until creamy and smooth. Gradually add the powdered sugar and continue mixing until fully combined and fluffy. Stir in the finely ground walnuts and cocoa powder. Add milk one tablespoon at a time until the frosting reaches a smooth, spreadable consistency.
- Assemble the Cake: Once the cake has completely cooled, carefully slice it horizontally into two layers. Spread an even layer of the walnut buttercream between the two layers, then use the remaining frosting to cover the top and sides of the cake evenly.
- Chill and Serve: Refrigerate the assembled cake for at least 30 minutes to allow the buttercream to set, which makes slicing easier and ensures clean cuts. Serve chilled or at room temperature.
