Swedish race tracks here means a playful, race-track-shaped decoration on a Swedish-inspired almond and cardamom sheet cake, not a traditional Swedish dish. Lingonberry preserves add a tart ribbon through the tender cake, while buttercream makes an easy road and marzipan can form low track barriers.
Ingredients
- 2 cups (250 g) all-purpose flour
- 1/2 cup (50 g) finely ground almond flour
- 1 cup (200 g) granulated sugar
- 2 teaspoons (8 g) baking powder
- 1 teaspoon (2 g) ground cardamom
- 1/2 teaspoon (3 g) fine salt
- 3 large eggs, about 5 ounces (150 g) without shells, at room temperature
- 1/2 cup (113 g) unsalted butter, melted and cooled slightly
- 3/4 cup (180 ml) whole milk, at room temperature
- 1 teaspoon (5 ml) vanilla extract
- 1/3 cup (105 g) lingonberry preserves, divided if desired; cranberry preserves are a practical substitute, though usually sweeter and less tart
- 3/4 cup (170 g) unsalted butter, softened, for the frosting
- 3 cups (360 g) powdered sugar, plus 1/3 cup (40 g) for lane markings
- 3 tablespoons (45 ml) milk, plus 1 to 2 teaspoons (5 to 10 ml) for lane-marking icing
- 1 teaspoon (5 ml) vanilla extract, for the frosting
- 2 tablespoons (10 g) unsweetened cocoa powder
- Green gel food coloring, a few drops, or 1 teaspoon (2 g) matcha powder for a muted green frosting
- 3 1/2 ounces (100 g) marzipan, optional, for edible barriers
- Small chocolate pieces or berries, optional, for finish-line markers
Instructions
- Heat the oven to 350°F (177°C). Grease a 9-by-13-inch (23-by-33-cm) baking pan and line the bottom with parchment, leaving a little overhang at the short sides to help lift out the cake. Bring the cold ingredients to room temperature while the oven heats. This helps the batter combine evenly and reduces the chance of a dense, uneven crumb.
- In a medium bowl, whisk together the all-purpose flour, almond flour, sugar, baking powder, cardamom, and salt. In a separate large bowl, whisk the eggs, melted butter, milk, and vanilla until smooth. Add the dry ingredients to the wet ingredients in two additions, stirring just until no dry flour remains. Avoid beating the batter; excessive mixing can make the cake tough.
- Scrape about half the batter into the prepared pan and spread it into an even layer. Spoon half the lingonberry preserves in small dots over the batter. Add the remaining batter and gently spread it to cover. Dot the rest of the preserves on top, then draw a butter knife through the top layer two or three times to make broad ribbons. Do not mix the jam completely into the batter or the cake may turn uniformly pink and lose the distinct fruit swirls.
- Bake for 25 to 30 minutes, rotating the pan once if your oven browns unevenly. The surface should spring back lightly when touched and a toothpick inserted into a cake-only spot should come out without wet batter. Because this batter contains eggs, the USDA FSIS safe minimum for egg dishes is 160°F (71°C); check the center with a food thermometer if you need to confirm it. If it has not reached that temperature, continue baking and check again after a few minutes.
- Set the pan on a cooling rack and leave the cake to cool completely, about 60 minutes. Do not frost a warm cake: the buttercream will soften and the road design can slide. Use the parchment to lift the cooled cake onto a board or leave it in the pan for serving. If you want a neat oval track, lightly mark an oval on the surface with a toothpick before decorating; the cake itself can remain rectangular.
- Make the frosting while the cake cools. Beat the softened butter until creamy, then gradually beat in the 3 cups powdered sugar, 3 tablespoons milk, and vanilla. If the frosting is too stiff to spread, add milk a teaspoon at a time; if it is loose, beat in more powdered sugar a tablespoon at a time. Transfer about one-third of the frosting to a small bowl and mix in the cocoa powder to make the road. Tint the remaining frosting green with a few drops of gel color. Matcha works as a natural-color option but adds a noticeable tea-like, slightly earthy flavor.
- Spread the green frosting in a thin, fairly even layer over the cooled cake. Spoon the chocolate frosting into a piping bag or a zip-top bag with a small corner snipped off. Pipe a wide oval or looping road on top, leaving a green center and green space around the outside. If you prefer a simpler design, spread the cocoa frosting into a winding lane with the back of a spoon; precision is not important for a homemade cake.
- Stir the extra 1/3 cup powdered sugar with 1 teaspoon milk. Add the second teaspoon only if needed to make a pipeable icing. Pipe short white lane dashes along the chocolate road. Knead the marzipan briefly until pliable, roll it into thin ropes, and place short sections around curves as barriers. Add chocolate pieces or berries as markers if using. Allow the decoration to settle for 10 minutes before cutting so the icing is less likely to smear.
Tips
- Use lingonberry preserves if you can find them in a Scandinavian grocery section or specialty shop. They bring a distinctive tartness that balances the sweet cake. Cranberry preserves work well when lingonberries are unavailable; reduce the sugar in the cake only if your substitute is especially sweet, and keep in mind that the fruit flavor will be less sharp.
- Measure flour by spooning it into the cup and leveling the top, or use the metric weight. Scooping directly from the bag packs in extra flour and can make the sponge dry. Almond flour should be finely ground; coarse almond meal gives the crumb a more noticeable texture.
- Keep the oval road fairly broad and the frosting layer thin. Very narrow piping is harder to make cleanly and can disappear when the cake is cut. For a softer green color, use just a little gel coloring; food coloring is stronger than matcha, which changes the flavor as well as the color.
- If you are serving young children, use marzipan barriers only if almond is suitable for your guests, and make sure everyone knows that it contains almonds. The marzipan is decorative rather than essential: leave it off for an easier design, or use small pretzel pieces as a salty, crunchy substitute.
Serving Suggestions
Cut the cake into 12 squares, aiming to give each piece some of the road and green frosting. A small sharp knife makes cleaner portions than a blunt one; wipe the blade between cuts if the chocolate icing begins to drag across the pale cake. For a party, you can cut the cake into 16 smaller pieces and set them on a platter so the track design is visible before serving.
Serve at room temperature, when the buttercream is soft and the cardamom aroma comes through clearly. Coffee or black tea makes a simple accompaniment, and unsweetened whipped cream is a good option if you want something cool alongside the sweet frosting. Extra lingonberry preserves can be offered in a small dish, especially for guests who like a brighter, fruitier bite.
The cake also works as a centerpiece for a racing-themed birthday or watch party. If using toy cars, place them on the board or on clean food-safe picks rather than directly on the cake, and remove them before slicing. That keeps the decoration practical and avoids mixing small non-edible pieces with the servings.
Variations
For a more pronounced Swedish-inspired flavor, add 1/4 teaspoon (about 0.5 g) ground cardamom in addition to the teaspoon in the recipe. Cardamom is already noticeable at the listed amount, so increase it gradually if your guests are unfamiliar with the flavor. A little finely grated lemon zest, about 1 teaspoon (2 g), gives the cake a fresher citrus note without changing the method.
For a nut-free version, replace the almond flour with 1/2 cup (60 g) more all-purpose flour. The result will be a little less rich and less almond-scented, but it will still hold the fruit swirl and decoration. Check packaged ingredients, including the marzipan and any decorations, for allergen information and cross-contact warnings.
You can make the cake as a simple frosted sheet cake without drawing a track: spread the green frosting over the top and serve the cocoa frosting or preserves on the side. For a chocolate-forward version, omit the green color and use the cocoa frosting for the whole surface, then pipe the lane lines in white. These approaches preserve the cake’s flavor while making decorating faster.
Storage and Reheating
Because the cake is frosted with buttercream and contains eggs and dairy, refrigerate it within 2 hours of serving. Cover the pan or store slices in an airtight container; the cake keeps well for 3 to 4 days in the refrigerator. Marzipan barriers may firm up in the cold, but they remain edible. For the best texture, let portions stand at room temperature for about 20 to 30 minutes before serving.
To freeze, arrange undecorated or fully set slices in a single layer until firm, then wrap them well and place them in a freezer-safe container for up to 2 months for best quality. Thaw in the refrigerator overnight, then bring to room temperature before serving. The frosting may look less smooth after thawing, and lane markings can soften, so freezing undecorated cake is the tidiest option. This cake does not need reheating; warming it can melt the frosting.
Frequently Asked Questions
Is this a traditional Swedish cake?
No. “Swedish race tracks” describes the decorative theme of this recipe, not a recognized traditional Swedish dish. The almond, cardamom, and lingonberry flavors are Swedish-inspired, but the sheet cake and race-course decoration are a modern party idea.
Can I use fresh lingonberries instead of preserves?
Fresh berries are much less sweet and release liquid, so they are not a direct one-for-one swap in the swirl. For a practical substitute, simmer 1 cup (150 g) fresh or frozen lingonberries with 1/3 cup (65 g) sugar and 1 tablespoon (15 ml) water for about 8 to 10 minutes, stirring until the berries burst and the mixture thickens. Cool it completely before using about 1/3 cup in the cake. Refrigerate any extra promptly.
Can I bake the cake a day ahead?
Yes. Bake and cool the cake, wrap it well, and refrigerate it overnight. You can frost and decorate it the next day, or decorate it ahead and keep it covered in the refrigerator. Allow a fully chilled cake about 20 to 30 minutes at room temperature before serving for a softer crumb and buttercream.
How can I tell whether the cake is done without a thermometer?
Look for a lightly golden surface that springs back when gently touched, and test a spot without a visible jam ribbon with a toothpick. It should come out without liquid batter. Oven timing varies, so begin checking at 25 minutes. A thermometer is the most direct way to verify the safe minimum for the egg-containing cake batter.
Can I make this without food coloring?
Yes. Leave the frosting white, or tint it with matcha for a muted green hue and a mild earthy flavor. You can also skip the green “grass” and make the chocolate road the main decoration on the plain cake. The theme will still read clearly once you add lane markings and optional barriers.
What pan can I use if I do not have a 9-by-13-inch pan?
A similar-size rectangular pan is the easiest substitute. A slightly smaller pan makes a taller cake and may need a few extra minutes; a larger pan makes a thinner cake and may bake sooner. Keep the batter depth in mind, start checking early or late accordingly, and confirm the center is set before removing it from the oven.
