Swiss kirsch cake, especially the version associated with Zug, is a celebratory layered cake of almond meringue, light sponge, kirsch syrup, and buttercream. This home-style recipe balances crisp, nutty layers with a tender center and cherry-scented filling; families and pastry makers vary the proportions and finishes, so it is one practical interpretation rather than the only version.
Ingredients
- 4 large eggs, separated while cold and brought to room temperature (about 200 g without shells)
- 1 cup (200 g) granulated sugar, divided: 1/2 cup (100 g) for the sponge and 1/2 cup (100 g) for the meringue
- 3/4 cup (95 g) all-purpose flour
- 2 tablespoons (16 g) cornstarch
- 1/4 teaspoon (1.5 g) fine salt
- 1 teaspoon (5 ml) vanilla extract
- 1 cup (100 g) finely ground almonds, preferably blanched
- 2 tablespoons (16 g) all-purpose flour for the almond meringue
- 1 cup (227 g) unsalted butter, softened but not greasy
- 2 cups (240 g) powdered sugar, sifted, plus 1 cup (120 g) for the glaze
- 1/4 cup (60 ml) kirsch, divided: 2 tablespoons (30 ml) for the buttercream, 2 tablespoons (30 ml) for the syrup, plus up to 1 tablespoon (15 ml) for the glaze
- 1/3 cup (80 ml) water
- 1/3 cup (67 g) granulated sugar for the syrup
- 2 to 4 tablespoons (30 to 60 ml) water for adjusting the glaze
- 1 to 2 drops pink food coloring, optional
- 1 tablespoon (8 g) powdered sugar for decorating, optional
Instructions
- Prepare the pans and oven. Heat the oven to 350°F (175°C). Line the base of one 8-inch (20 cm) round cake pan with parchment. Draw two 8-inch circles on another piece of parchment, turn the pencil side down, and place it on a baking sheet. If you have only one baking sheet, bake the meringue rounds one after the other. Keep the pan and bowl used for the egg whites free of grease.
- Make the sponge batter. Separate the eggs, placing the whites in a clean bowl and the yolks in a second bowl. Beat the yolks with 1/2 cup (100 g) sugar for 3 to 4 minutes, until thick and pale, then beat in the vanilla. Sift together the 3/4 cup (95 g) flour, cornstarch, and salt. Fold the dry mixture into the yolks just until no dry patches remain. In a clean bowl, beat the egg whites to soft peaks, gradually add the remaining 1/2 cup (100 g) sugar, and continue beating until glossy peaks form. Fold one-third of the whites into the yolk mixture to loosen it, then gently fold in the rest. Stop when the batter is evenly combined; vigorous mixing knocks out the air that gives the sponge its lift.
- Bake the sponge. Spread the batter in the prepared cake pan and level the top. Bake for 20 to 23 minutes, until the center springs back lightly when touched and a tester comes out without wet batter. For egg safety, check the center with a food thermometer: the USDA FSIS safe minimum for egg dishes is 160°F (71°C). Cool in the pan for 10 minutes, turn out onto a rack, remove the parchment, and cool completely, about 30 minutes. Wash and dry the cake pan if you will use it to guide the meringue rounds.
- Make and bake the almond meringue. Reduce the oven to 300°F (150°C). Beat the remaining egg whites only if you reserved separate whites; for this recipe, use the same four whites separated for the sponge before making the sponge batter only if you kept them aside. Since the sponge uses all four separated whites, instead separate 2 additional eggs for the meringue, using their whites here and saving their yolks for another use. Beat these 2 egg whites in a clean bowl to soft peaks. Gradually beat in 1/2 cup (100 g) sugar until the meringue is glossy and holds firm peaks. Fold in the ground almonds and 2 tablespoons (16 g) flour. Divide the mixture between the two marked circles and spread it evenly to the edges, keeping the discs about the same thickness. Bake for 35 to 40 minutes, until dry to the touch and lightly colored. Turn off the oven, leave the door ajar, and let the discs cool for 45 minutes before peeling away the paper carefully.
- Cook the syrup. While the layers bake, combine 1/3 cup (67 g) sugar and 1/3 cup (80 ml) water in a small saucepan. Bring to a simmer, stirring until the sugar dissolves, then simmer for 1 minute. Take the pan off the heat and cool for 10 minutes. Stir in 2 tablespoons (30 ml) kirsch. The syrup should be cool before it touches the sponge so it moistens the cake without making it gummy.
- Make the buttercream. Beat the softened butter with the 2 cups (240 g) sifted powdered sugar on low speed until the sugar is incorporated, then beat on medium for 2 to 3 minutes until smooth and pale. Beat in 2 tablespoons (30 ml) kirsch, adding it gradually. If the cream looks curdled, continue beating for a minute; if it is very soft, chill it for 10 to 15 minutes, then beat again. Set aside about 1/2 cup (roughly 100 g) for coating the outside of the cake.
- Assemble the layers. Put one meringue disc on a flat serving plate or cake board. Spread about one-third of the remaining buttercream over it in a thin, even layer. Place the cooled sponge on top. Brush the syrup over the sponge in several passes, using enough to moisten it evenly but not so much that liquid pools at the edge. Spread another third of the filling over the sponge, then add the second meringue disc. Use the reserved buttercream to cover the top and sides in a very thin coat. This crumb coat helps the glaze sit neatly; it does not need to hide every ridge in the layers.
- Chill and glaze. Refrigerate the assembled cake for 2 hours 30 minutes, or until the buttercream is firm. Stir 1 cup (120 g) powdered sugar with 1 tablespoon (15 ml) kirsch and 2 tablespoons (30 ml) water. Add more water a teaspoon at a time until the glaze is thick but pourable. Tint pale pink if desired. Pour it over the chilled cake and guide it toward the edges with a small spatula. Refrigerate for 15 to 20 minutes to set. For a traditional-looking finish, sift the optional powdered sugar over a paper stencil just before serving; avoid covering the glaze until it has set.
Tips
- Keep the meringue bowl clean. Even a trace of yolk or grease can prevent egg whites from whipping properly. Separate eggs one at a time into a small cup, then transfer each white to the mixing bowl so one broken yolk does not spoil the batch.
- Use kirsch thoughtfully. Kirsch is a clear cherry eau-de-vie and gives this cake its distinctive aroma. If it is hard to find or you prefer a nonalcoholic cake, replace it in both syrup and buttercream with tart cherry juice. The filling will taste fruitier and sweeter, so reduce the syrup sugar slightly if the juice is sweetened. The glaze can use water and a little cherry juice instead.
- Handle the discs gently. Almond meringue can crack while you move it, especially if it is warm. Let it cool fully, lift it with both hands or a wide cake lifter, and remember that a small crack can be placed inward and covered with buttercream.
- Keep the filling smooth. Butter that is too cold can make buttercream lumpy, while butter that is melting can make it slack. Aim for butter that yields to a fingertip but still holds its shape, and let the sponge and meringue cool completely before assembly.
Serving Suggestions
Serve the cake cold enough for tidy slices but not straight from the refrigerator. Set it on the counter for about 20 minutes, then use a long, sharp knife warmed in hot water and wiped dry between cuts. This helps the blade pass through the crisp meringue without dragging the filling. Cut modest wedges: the cake is rich, and its layered texture is easiest to appreciate when the sponge, buttercream, and almond meringue all stay in each bite.
Offer it with unsweetened coffee or black tea, which balances the sweet glaze and buttercream. Fresh cherries make a natural seasonal garnish, but they are optional; add them just before serving rather than storing the cake with wet fruit on top. If serving guests who avoid alcohol, label the cake clearly when it contains kirsch. Kirsch added to the syrup and glaze is not cooked off, so use the juice substitution for an alcohol-free version.
Variations
Make a simpler round. If two meringue discs feel delicate to manage, bake the almond meringue as one disc and split the sponge horizontally once it is completely cool. Layer the meringue, buttercream, one sponge half brushed with syrup, more buttercream, and the second sponge half. It will have a softer, more cake-like profile and less crisp meringue in each slice.
Change the nut. Finely ground hazelnuts can replace the almonds in equal weight. They make the meringue more deeply toasted and nutty, though the result is less typical of the almond-forward version described here. Use nuts ground to a fine meal rather than a coarse chop so the discs spread evenly and hold together.
Adjust the finish. A simple white kirsch glaze is suitable if you do not want pink coloring. For a less sweet finish, skip the glaze and spread a thin layer of buttercream over the top, then dust it with powdered sugar shortly before serving. The glaze gives a smooth, decorative cap, while the buttercream finish is softer and easier to cut.
Storage and Reheating
Because the cake contains buttercream, refrigerate it within 2 hours of assembly or serving. Cover it once the glaze has set, using a cake carrier or a loose cover that will not touch the surface. It keeps for 3 to 4 days refrigerated, although the meringue gradually softens as it absorbs moisture from the filling. For the best contrast between crisp layers and soft sponge, serve it on the day it is assembled or the following day.
There is no need to reheat this cake. Let refrigerated slices stand at room temperature for about 15 to 20 minutes to soften the buttercream slightly. You can freeze individual slices, well wrapped, for up to 1 month; thaw them overnight in the refrigerator, then briefly at room temperature before serving. The meringue may lose some crispness after freezing, so freezing is practical for leftovers rather than the first choice for presentation.
Frequently Asked Questions
Is Swiss kirsch cake the same as Zuger Kirschtorte?
They are closely related names, and Zuger Kirschtorte is the well-known Swiss cake associated with the canton and town of Zug. This recipe uses its recognizable combination of almond meringue, sponge, kirsch, and buttercream, but home and bakery versions differ in layer proportions, icing, and decoration.
Can I make the cake a day ahead?
Yes. Assemble and glaze it the day before, then keep it covered in the refrigerator. The flavors settle and the cake slices cleanly after chilling, though the meringue becomes less crisp over time. For a crisper texture, bake the meringue discs a day ahead and store them in an airtight container at room temperature, then assemble the cake closer to serving.
What can I use instead of kirsch?
Tart cherry juice is the most straightforward nonalcoholic substitute. Use it in the syrup, buttercream, and glaze, adding it gradually because juice is less concentrated than kirsch and can loosen the buttercream. A small amount of almond extract can add a fragrant note, but use only a drop or two because it can quickly dominate the cherry and almond flavors.
Why did my meringue discs crack or turn chewy?
Small cracks are common and can be hidden in the assembled cake. Chewy discs often mean they were not dried long enough, were removed from the oven while still warm and damp, or were exposed to humidity. Bake until the surface feels dry, leave the discs in the switched-off oven with the door ajar for the stated cooling period, and store them airtight if assembling later.
Can I bake the layers in advance?
Yes. The sponge can be wrapped once completely cool and kept at room temperature for up to 1 day, or frozen for up to 1 month. Store fully cooled meringue discs airtight in a dry place for up to 1 day; do not refrigerate them before assembly, since refrigerator moisture can make them sticky. Thaw frozen sponge while still wrapped so condensation forms on the wrapping rather than the cake.
How do I get neat slices through the meringue?
Chill the cake until the buttercream is firm, then use a long, thin knife warmed under hot water and wiped dry. Press down gently rather than sawing aggressively, and clean and warm the blade again between slices. If the top disc is especially crisp, start the cut with the knife tip and work through it carefully before cutting the softer sponge and filling.
