Homemade Flourless Chocolate Cake, freshly made and ready to serve

Flourless Chocolate Cake

Most flourless chocolate cakes are round. This one’s baked in a loaf pan, which means neat, fudgy slices instead of wedges that fall apart. It’s basically chocolate, butter, sugar and eggs, plus some cocoa powder and a teaspoon of espresso powder that you won’t taste as coffee. It just makes the chocolate taste more like chocolate.

Use an instant-read thermometer if you have one, and take the cake out when the center hits 200°F. I used to pull it early because the middle looked wobbly, and it sank. It’s better the next day, honestly, after a night in the fridge firms it up. Let it warm up a bit before serving, and dust it with powdered sugar.

A flourless chocolate cake baked in a loaf pan, so it cuts into clean, fudgy slices. It has a thin crackly top and a dense center. There's no flour or starch in it at all, and it only takes about 15 minutes to put together before it goes in the oven.

Ingredients
  

  • 1 cup semisweet or bittersweet chocolate chips (about 170 g)
  • 8 tablespoons unsalted butter (about 113 g, cut into pieces)
  • 3/4 cup granulated sugar (about 149 g)
  • 1/4 teaspoon table salt
  • 1 teaspoon espresso powder (optional; deepens the chocolate flavor without tasting like coffee)
  • 1 teaspoon vanilla extract
  • 3 large eggs (at room temperature)
  • 1/2 cup Dutch-process cocoa powder (about 42 g; sifted if lumpy)
  • powdered sugar (for dusting before serving)

Equipment

  • 8.5 x 4.5 inch loaf pan
  • Parchment paper
  • Medium saucepan or double boiler
  • Instant-read thermometer
  • Mixing bowl
  • Whisk

Method

  1. Preheat your oven to 350°F. Line an 8.5 x 4.5 inch loaf pan with parchment paper, leaving an overhang on the long sides so you can lift the finished cake out cleanly.
  2. Combine the chocolate chips and butter in a medium saucepan over low heat, stirring frequently until both are fully melted and the mixture is glossy and smooth. Remove from the heat.

  3. Whisk the granulated sugar, salt, espresso powder, and vanilla extract into the warm chocolate mixture until fully incorporated. Add the eggs one at a time, whisking well after each addition — the batter will thicken and turn glossy as each egg goes in.
    3/4 cup granulated sugar, 1/4 teaspoon table salt, 1 teaspoon espresso powder, 1 teaspoon vanilla extract, 3 large eggs, 1/2 cup Dutch-process cocoa powder, powdered sugar
  4. Sift the Dutch-process cocoa powder directly into the batter and whisk until the mixture is completely smooth with no dry streaks. Pour the batter into the prepared loaf pan and spread it into an even layer.
  5. Bake for about 40 minutes, until the top forms a thin, dry crust and an instant-read thermometer inserted into the center of the loaf reads at least 200°F. This temperature check is the most reliable way to confirm the interior is fully set and the cake will slice cleanly once cooled.
  6. Let the cake rest in the pan for 10 minutes, then use the parchment overhang to lift it onto a wire rack. Allow it to cool completely before slicing — the fudgy center firms up as it cools. Just before serving, dust generously with powdered sugar.

Notes

For the cleanest slices, refrigerate the fully cooled loaf for at least 1 hour before cutting — a sharp knife wiped between cuts keeps the edges neat. Store leftovers wrapped at room temperature for up to 3 days, or refrigerate for up to a week.
