Black Chocolate Cake

Nine ingredients, one pan, and a trick that makes all the difference: the chocolate gets boiled with milk and sugar into a thick syrup before it ever touches the batter. That cooked chocolate base is what gives this cake its pitch-dark color and dense, fudgy crumb.

Boil the unsweetened chocolate, half a cup of sugar, and half a cup of milk together, stirring constantly until the mixture thickens. It should coat the back of a spoon. Then step away and let it cool completely. Pouring hot chocolate syrup into the batter will scramble the eggs and melt the butter unevenly.

The rest is straightforward. Cream the butter with the remaining sugar, beat in the eggs and milk, fold in the sifted flour and baking soda, then add the cooled chocolate. Two minutes of beating on medium speed brings it all together into a glossy, dark batter.

Sifting the flour matters here. This is a dense cake by design, and unsifted flour will make it heavy rather than fudgy. Sifting aerates the flour and helps it incorporate smoothly.

Pro Tips

• Cool the chocolate syrup to room temperature before mixing. Warm is fine, but hot will ruin the batter’s structure.
• Don’t overbeat once the flour is added. Two minutes is enough. More mixing develops gluten and makes the cake tough.
• Test at 22 minutes. A toothpick should come out with moist crumbs, not wet batter. Overbaking dries out the fudgy center.
• This cake is rich enough to serve unfrosted with just a dusting of powdered sugar, or top with chocolate ganache for a full chocolate experience.

Variations

• Mocha: Add 2 teaspoons of instant espresso powder to the boiling chocolate mixture for a coffee-chocolate depth.
• Mexican chocolate: Stir in a teaspoon of cinnamon and a pinch of cayenne with the dry ingredients.
