Why It Works
- Espresso enhances the chocolate’s bittersweet and fruity notes.
- Cornstarch helps thicken the chocolate frosting, whereas gelatin helps the frosting set and keep set—even on a scorching and humid day.
Final October, on a go to residence to Singapore, I listened to my aunt gush about Lana Desserts, a famed Singaporean cake store that has been in enterprise since 1964. Although I had by no means tasted their muffins, I’d heard loads of nice issues concerning the bakery and its fudgy chocolate cake. For a few of my associates, celebrating their birthdays with the favored chocolate cake was a household custom spanning a long time. Stunned that I’d by no means tasted this iconic deal with, my aunt purchased a cake for me to strive. Regardless that it was a blisteringly scorching day—temperatures in Singapore usually vary from 86 to 95ºF (30 to 35ºC)—the confection was pristine. The frosting hadn’t melted and the ornamental ripples in it remained immaculate.
I took a chew of the cake. Its tenderness and intense chocolate taste shocked me: It was like consuming a bar of darkish chocolate, however in cake kind. The frosting, particularly, made the dessert really feel each acquainted but utterly totally different from another chocolate cake I’ve had previously. The frosting curiously toed the road between ganache and gel: It was set sufficient that it didn’t go away a multitude even after I picked up a slice with my hand, but nonetheless managed to have a creamy, melt-in-the-mouth high quality. As soon as I received again to the Netherlands, the place I reside right now, I used to be desirous to recreate the dessert in my residence kitchen.
Key Strategies for Making the Cake
Handle the warmth rigorously when making the frosting . By means of my testing, I discovered that for one of the best frosting, it’s essential convey the cornstarch, sugar, and water to a bubble—which helps the starches gelatinize—then instantly take away the pot from the warmth earlier than whisking within the gelatin and chocolate. I discovered that if I allowed the frosting to boil vigorously after including the chocolate, it turned stiff and grainy—not the shiny, barely-set impact of Lana Desserts’ chocolate cake. That is seemingly as a result of the chocolate overheated; when the ingredient reaches 145ºF (62ºC), it begins to grab and break. The ensuing frosting is simply thick sufficient to drape over the cake, and because the combination cools, the gelatin units it, leading to a pristine chocolate frosting that stays intact even in scorching and humid tropical climate.
Use Dutch-process cocoa powder and low. To recreate the unapologetically wealthy and intense taste of the dessert, I used satan’s meals cake—which has a dramatically darkish crumb, deep chocolate taste, and is splendidly tender —as my place to begin. There are two broad classes of cocoa powder: pure cocoa powder and Dutch-process cocoa powder. Pure cocoa powder is of course acidic and has a pH between 5 and 6, however Dutch-process cocoa powder is washed with a potassium carbonate resolution that neutralizes the cocoa’s pH to seven. This produces a barely darker cocoa powder that offers baked items, together with this chocolate cake, a deeper brown hue. Right here, the addition of espresso enhances the cocoa powder’s fruity, bittersweet notes, leading to a deeply chocolate-y dessert.
For the straightest edges, bake the cake in a Pullman loaf pan. Utilizing an oblong pan with straight edges not solely replicates the look of the unique Lana Desserts creation, but in addition creates a neat cake that’s straightforward to evenly degree and drape in frosting. If you happen to don’t have a Pullman loaf pan, you should use an everyday 9- by 4-inch loaf pan—however as a result of an everyday loaf pan is way shorter than a Pullman loaf pan, you’ll should take away a half cup of cake batter earlier than baking, which is able to forestall the batter from spilling over the perimeters because it bakes. (That half cup of batter makes for a really single-serving cake. Simply place it in a greased ramekin and bake till simply agency to the contact, 15 to twenty minutes.)

Suggestions for Nailing the Chocolate Pudding Frosting
Bloom your gelatin. Blooming gelatin—sprinkling gelatin powder over chilly water so it could actually totally hydrate—prevents it from clumping up and helps it dissolve evenly into no matter it’s added to.
Incorporate cornstarch and gelatin into the frosting. In my analysis, I used to be shocked to study that the frosting wasn’t a ganache or buttercream, however reasonably a starch-thickened one which’s ready on the range. To make it, you cook dinner a mix of cornstarch, sugar, and water till it simply bubbles, then take away it from the warmth and whisk in bloomed gelatin and chopped darkish chocolate till easy.
On-line sources suggest utilizing mung bean starch to organize the cake’s frosting; the ingredient is often used to make kueh, little snacks and confections extensively eaten all through Southeast Asia. Since mung bean starch is just not as available as cornstarch in lots of nations, together with the US, I experimented with each. Whereas the frosting made with mung bean starch was barely lighter in texture in comparison with cornstarch, there have been very minimal variations, and I’ve no hesitation in recommending cornstarch on this recipe.
