THE NEW YORK TIMES RECIPE: How did Black Forest cake become the world’s favourite dessert?

It’s a classic Trinidadian dessert — a chocolate cake soaked in overproof rum and topped with swoops of ultrapasteurized whipped cream.

But wait: It’s also a signature Pakistani cake, saturated with cherry brandy essence. And a Chilean cake, festooned with locally grown cherries. And a Lebanese cake — not too sweet, with little to no alcohol. And a Nepali cake. And a Zimbabwean cake. It’s even popular on the remote islands of Fiji.

What kind of dessert could inspire such a territorial dispute?

It’s Black Forest cake, named for a corner of Germany that still conjures images of lederhosen and fairy tales.

Try telling that to the rest of the world. The cake, long an adopted favourite in many countries, is more popular than ever — except perhaps in Germany. Thanks in part to a recent wave of ’90s-era nostalgia among younger generations, it’s found new life on social media and in restaurants across the world. Google searches for “Black Forest cake” have nearly doubled in volume over the last 10 years, most of them seeking a recipe.

Today, Black Forest cake belongs to everyone and no one. It’s the Danish butter cookie tin of desserts — a European artifact that has come to transcend cultures. In fact, several people interviewed for this article were astonished to hear that the cake didn’t hail from their native country.

The traditional version layers brandy-infused chocolate spongecake with airy whipped cream and cherry ornaments. But Natasha Laggan, 40, who runs a Trinidadian cooking account on Instagram and YouTube and lives in Davie, Florida, long believed that the traditional liquor for the cake was rum — the spirit used in most of the restaurant versions she ate during her childhood in California, Trinidad.

Kudakwashe Makoni, 44, a chef from Harare, Zimbabwe, insisted that his nation’s cows lend a distinctly rich flavour to the cake’s cream. “Nobody does a Black Forest like Zimbabwe,” he said.

When his family moved to Dallas in 2000, he was shocked to see Black Forest cake at a local bakery. He wondered: Why was an American shop serving a Zimbabwean dessert?

The cake’s very name proclaims its Teutonic origin. But some people said they thought “Black Forest” referred to the chocolate shavings on the cake.

Sumayya Usmani, a Glasgow, Scotland, food writer and cookbook author from Karachi, Pakistan, long thought the Black Forest was a sort of fantasy realm. “It had this Narnia image in my mind, where there is beautiful snow and cherries and chocolate shavings,” she said.

In Pakistan, the cake is a staple of any respected bakery, said Usmani, 51. It is “exotic and foreign, but very much part of the culture.”

Dessert trends come and go, yet Black Forest remains the cartoonish archetype of a celebration cake, with its eye-catching cherry garnish and contrasting black-and-white layers.

If you can only get canned cherries and slightly dubious UHT whipped cream, if you can only get compound chocolate, you can still make something that looks like a Black Forest.

“It looks like the kind of cake you would draw if you were a child and you were drawing the perfect cake,” said Helen Goh, a cookbook author in London.

That simplicity, and a flavor combination that can feel both familiar and unfamiliar, may help explain how a cake from Germany — a country that exerts a narrow culinary influence globally — captivated such an expansive audience.

The first time Kashish Shrestha, 41, a writer and photographer, tasted Black Forest cake at a bakery in Kathmandu, Nepal, the texture reminded him of ras malai, a milky, spongy South Asian sweet. In Nepal, “Black Forest” is often used as a generic term for any kind of cake, he said.

Ramin Ganeshram, a Trinidadian American culinary historian in Westport, Connecticut, said the cake recalled the rum-soaked Caribbean black cake.

As a child in Singapore, cookbook author Sharon Wee thought of Black Forest cake as a fancier version of chiffon cakes, which became popular there in the 1950s. Serving her friends a Black Forest cake on her birthday was a status symbol — “like toting your Hermès bag to primary school,” said Wee, 53, who splits her time between New York City and Singapore.

The same cannot be said in Germany, where the cake is seen as “sort of old-fashioned,” said Janosch Förster, a research fellow at the German Archive of Culinary Arts.

Both its creator and birthplace are still a matter of debate; some say it came from the Black Forest region, others say Berlin. But it is unquestionably a German invention, from sometime in the early 20th century.

“It is basically just a standard, not-so-interesting cake,” said Andreas Klöckner, CEO of Goldhahn und Sampson, a culinary store and cooking school in Berlin. “It has a different standing outside Germany as something special.”

The cake’s travels most likely occurred as Germans moved around the world as immigrants, missionaries, chefs in high-end hotels and refugees escaping Nazism in the 1930s — or Nazis fleeing after World War II, said José López Ganem, the executive director of the Fine Cacao and Chocolate Institute in Cambridge, Massachusetts.

One of the most effective proselytizers of Black Forest cake was probably the British Empire, said Carla Martin, the institute’s president.

“There was a lot of German technique and German cuisine that got spread through British association,” she said. “They were the capital centre of the world. They were taking traditions of the European continent and expanding them, and they were the best at it.”

Black Forest cake had a lot going for it. Its ingredients, particularly cocoa powder, were becoming more readily available, said Ganeshram, the culinary historian. The alcohol preserved the cake, extending its shelf life in tropical climates.

The cake could also be easily adapted: Bakers in Muslim-majority countries, for example, often omit the liquor, and some Singaporean recipes call for blueberry jam, which can be less expensive than cherries.

These modifications speak to the resilience of colonized communities, Ganeshram said. “This may have been brought here to a place it doesn’t necessarily belong, but we are going to take it and adapt it and make it our own.”

Neither the flavours nor the appearance of Black Forest cake align with current pastry trends. Desserts today “are more sophisticated,” said Dorie Greenspan, the renowned cookbook author. “They are sparer. They are not so over-the-top.”

Still, several pastry chefs are giving the nostalgic cake a creative update.

It arrives as a roulade at Thistle & Leek, a neighbourhood restaurant in Newton, Massachusetts, and in a jar at Swadesi, a new Indian-inspired bakery in Chicago. (Swadesi’s owner, Sujan Sarkar, once believed that Black Forest cake came from Kolkata, India, where as a child he saw many of the city’s Christians preparing cakes during the holidays.)

At his Kayu Bakehouse locations in London, Dubai and Abu Dhabi, United Arab Emirates, and Riyadh, Saudi Arabia, Lebanese chef Karim Bourgi adorns his version with whipped vanilla ganache and dark chocolate crémeux. Heena Punwani, the owner of Maska Bakery in Mumbai, India, fields weekly messages asking when her Black Forest cake with chocolate mousse and Kashmiri cherry compote will make its return.

Christopher Tan, the author of the Singaporean dessert cookbook “The Way of Kueh,” described Black Forest cake as “indestructible,” because it can be a dressed-up confection or a simple grocery store treat.

“If you can only get canned cherries and slightly dubious UHT whipped cream, if you can only get compound chocolate, you can still make something that looks like a Black Forest,” he said.

Tan grew up in a family that bought the cake from pastry shops at luxury hotels in Singapore, but a decade ago, he had the chance to try it straight from the source. On a working trip to Germany, he visited Ulm, a city near the Black Forest, going from bakery to bakery in search of the cake. But no one served it — the owners all said it was passé.

“On those four days in Germany, in Frankfurt and in Ulm, the only Black Forest cake I saw on that trip was on board my flight,” he said. “On Thai Airways.”

Recipe: Black Forest Cake

By Samantha Seneviratne

Black Forest cake, which originated in the Black Forest region of Germany, is typically made with a light chocolate sponge cake, soaked with cherry syrup and cherry brandy (Kirsch), then layered with whipped cream and cherries. This version swaps the chocolate sponge for a denser, fudgier chocolate cake to delicious effect. But slicing a rich chocolate cake into four thin layers can be a bit tricky. To make the job a little easier, cool them completely before slicing. The cherry jam and syrup can be made in advance.

Yield: 8 to 10 servings

Total time: 1 1/2 hours, plus chilling

Ingredients:

For the Cake:

1 cup/240 millilitres vegetable oil, plus more for greasing the pans

1 1/2 cups/140 grams Dutch-process cocoa powder

1 1/2 cups/360 millilitres boiling water

1 cup/240 millilitres buttermilk

4 large eggs

1 1/2 cups/330 grams packed dark brown sugar

1 1/2 teaspoons pure vanilla extract

3 cups/385 grams all-purpose flour

1 tablespoon baking powder

1 1/2 teaspoons kosher salt

3/4 teaspoon baking soda

For the Cherry Jam:

4 cups (about 20 ounces/600 grams) fresh or frozen dark sweet cherries, pitted

1/2 cup/100 grams granulated sugar

1 teaspoon cornstarch

1/4 teaspoon almond extract

1 to 2 tablespoons Kirsch

For the Whipped Cream and Assembly:

1/3 cup/40 grams powdered sugar

1 tablespoon cornstarch

4 cups/960 millilitres heavy cream

6 ounces/170 grams bittersweet chocolate, shaved into curls

8 fresh or frozen whole dark sweet cherries, pitted

Preparation:

1. Heat the oven to 350 degrees. Grease two 9-inch round cake pans with oil and line the bottom of each with parchment paper.

2. To prepare the cake, in a large bowl, whisk together the cocoa powder and boiling water until smooth. Add the buttermilk and 1 cup vegetable oil, and whisk to combine. Add the eggs, brown sugar and vanilla extract, then whisk to combine.

3. In a medium bowl, whisk together the flour, baking powder, salt and baking soda. Add the dry ingredients to the wet, then whisk to combine. Divide the batter evenly between the two pans.

4. Bake until a toothpick inserted into the centre comes out clean, 30 to 35 minutes. Transfer the cakes to a rack to cool for about 20 minutes, then flip the cakes out onto the rack and let them cool completely. Flip the cakes again, so the domed portion is on top, and trim a bit of the dome off each cake to flatten the top. Carefully cut each layer in half horizontally, creating four layers.

5. While the cake cools, prepare the cherry jam: In a small saucepan, combine the cherries and sugar over medium heat. Cook, stirring occasionally and breaking the cherries down with a wooden spoon or potato masher, until the fruit has released its juice, about 6 minutes.

6. Pass the cherry mixture through a fine-mesh sieve, reserving the syrup in a medium bowl and setting aside the cooked cherries. Measure out 1/2 cup/120 millilitres of the syrup. (If you have more, store the rest in the refrigerator for another use). Transfer 1 tablespoon syrup from the 1/2 cup to a small bowl, then stir the Kirsch into the remaining syrup; set aside to cool completely.

7. Add 1 teaspoon cornstarch to the reserved 1 tablespoon cherry syrup in the small bowl; whisk to combine. Transfer it to the saucepan, add the cooked cherries and cook over medium, stirring, until the mixture has thickened, 3 to 5 minutes. Transfer to a bowl to cool completely. (You should have about 1 1/4 cups/300 millilitres jam.)

8. Prepare the whipped cream: In a small saucepan, whisk together the powdered sugar, cornstarch and 1 cup heavy cream. Bring that mixture to a low boil over medium heat and cook, stirring, until thickened to the consistency of thin pudding, reducing heat as necessary to avoid scorching, about 2 minutes. Transfer the cream mixture to a large bowl to cool completely.

9. Assemble the cake: Whisk the cream mixture to loosen it, then add the remaining 3 cups of heavy cream. Using an electric mixer on medium, beat the mixture until you have medium-stiff peaks, about 2 minutes. Set one cake layer on a serving plate, cut side up. Brush it with some of the cherry Kirsch syrup, spread about 1 cup of whipped cream over the top, then 1/3 of the cherry jam. Swirl the jam and the cream together a bit to spread it out evenly. Repeat this process two more times and top it with the last cake layer, cut-side down. Then cover the entire cake with a thin layer of whipped cream. Refrigerate for 30 minutes.

10. To finish, frost the cake with the remaining whipped cream. Prepare the chocolate curls: Warm the chocolate bar in the microwave for 10 to 15 seconds, then use a vegetable peeler to create curled chocolate shavings. Press the chocolate shavings onto the sides of the cake and over a 1-inch of the border on top. Top with the 8 cherries. Store leftovers, well wrapped, in the refrigerator for up to 3 days.
