This 5-Ingredient Chocolate Cake Is the Emergency Dessert Your Sweet Tooth Has Been Waiting For
When the chocolate craving hits, the last thing anyone wants is a recipe that requires a grocery run, three mixing bowls, and a degree in pastry arts. This rich, flourless chocolate cake keeps things refreshingly simple, relying on just five core ingredients, dark chocolate, butter, eggs, sugar, and cocoa powder, to deliver a dessert with a crackly top, a fudgy center, and serious dinner-party energy.
It is the kind of cake that makes a strong case for always keeping a bar of dark chocolate in the pantry. No flour to measure, no frosting to perfect, and no complicated decorating plan. Just melt, whisk, fold, bake, and wait for the hardest part: letting it cool long enough to slice.
Five ingredients, one seriously chocolatey result
The five-ingredient formula comes from a flourless chocolate cake recipe by chefs Sarit Packer and Itamar Srulovich, published by BBC Food. Their version calls for salted butter, dark chocolate, eggs, caster sugar and sifted cocoa powder; crème fraîche is suggested as an optional serving addition rather than one of the cake’s essentials.
The ingredient list may be brief, but every item has a specific job. Dark chocolate provides the deep, rounded flavor and the dense base; butter gives the cake richness and a smoother texture. Eggs do much of the structural work that flour would normally handle, while sugar brings sweetness and helps the whisked egg whites form a stable, airy foam. Cocoa powder intensifies the chocolate flavor and adds depth to the finished cake.
The recipe isn’t designed to produce a tall, fluffy, birthday-cake-style sponge. Instead, it lands somewhere beautifully indulgent: between a brownie, a baked chocolate mousse and a flourless torte. BBC Food describes it as “the most delicious, fudgy, flourless chocolate cake,” and the finished cake is expected to rise, crack on top and retain “a very slight wobble in the centre” when it comes out of the oven.
That little wobble is not a failure. The cake continues to settle as it cools, and the center naturally sinks somewhat, creating the kind of rustic, dramatic look that needs little more than cocoa powder, berries, or a spoonful of crème fraîche. In fact, a slight collapse is part of the charm, not evidence that something has gone wrong.

The technique is simple, but the folding matters
Preheat the oven to 400 degrees Fahrenheit, or 200 degrees Celsius, and grease and line a 9-inch springform pan. BBC Food’s method begins by melting 250 grams each of salted butter and dark chocolate together, either in a heatproof bowl over gently simmering water or carefully in a microwave, then letting the mixture cool slightly.
While the chocolate cools, separate six eggs. Whisk the yolks with 250 grams of sugar for about three minutes, until the mixture becomes pale and thick, then stir in the melted chocolate-butter mixture and 60 grams of sifted cocoa powder. That is your intensely chocolatey base, but the egg whites create the cake’s lighter lift.
In a clean bowl, whisk the egg whites until stiff peaks form. Then fold them into the chocolate mixture gradually, adding about one quarter of the whipped whites at a time. This is the only moment when gentle handling really matters: fold with a spatula, working through the center and around the sides of the bowl, rather than stirring aggressively. Keep as much air in the mixture as possible.
That approach lines up with guidance from King Arthur Baking, which recommends folding a portion of whipped egg whites into a chocolate mixture first to lighten it, then folding in the remaining whites only until no streaks remain. The technique helps preserve the air whipped into the whites, which gives chocolate cakes lift and tenderness rather than a heavy, compact finish.
Pour the batter into the prepared pan, level the top and bake for 35 to 40 minutes. The BBC Food recipe says the cake should rise and crack, with a center that still has a slight wobble. Let it cool in the tin on a wire rack; it will sink in the middle as it cools, which is normal for this style of flourless cake.
Make it feel special without overcomplicating it
A cake this rich doesn’t need a towering layer of buttercream, elaborate piping, or an overloaded topping bar. It is already built to be the star of the plate. A light dusting of cocoa powder will emphasize its dark, bakery-window look, while a spoonful of crème fraîche provides a cool, tangy contrast to the cake’s sweetness.
Fresh raspberries, strawberries, or cherries also work well because their acidity cuts through the butter-and-chocolate richness. If you want to lean into the full dessert moment, serve each slice slightly warm with vanilla ice cream. If you are after something more grown-up and less sugary, a small pour of espresso or strong coffee alongside the cake is a natural match.
Nigella Lawson’s chocolate cloud cake uses a related flourless format, dark chocolate, butter, eggs, and sugar, and describes the style as “a melting, dark, flourless, chocolate base” that “sinks damply on cooling.” Lawson credits food writer Richard Sax with describing the experience as “intensity, then relief, in each bite,” which is a pretty accurate summary of why flourless chocolate cake never needs a complicated sales pitch.
Because the cake contains eggs, bake it through safely, even if you prefer a fudgy interior. USDA guidance says egg dishes should reach an internal temperature of 160 degrees Fahrenheit, measured with a food thermometer. That does not mean the center needs to be dry; it means the cake should be properly set and safely cooked before it lands on the dessert table.
This isn’t a shortcut cake pretending to be something it isn’t. It is a deliberately simple, fudgy chocolate dessert that earns its place in your regular baking rotation because it feels impressive without making you work for it all afternoon. Keep the five ingredients on hand, and your next late-night chocolate craving may actually be the best thing that happens to your evening.
