Flourless Chocolate Cake Recipe

This cake is easy to put together and is naturally gluten-free. It can be finicky so be sure and follow all the directions and use the ingredients called for. It’s super rich and fudgy tasting, so a little goes a long way. Chocolate lovers will obsess over this cake.

  • 3 large eggs room temperature
  • 4 ounces semi-sweet baking chocolate such as Ghiradelli or Baker’s
  • ½ cup (113g) unsalted butter, sliced into tablespoons
  • cup (133g) granulated sugar
  • ½ cup (40g) unsweetened cocoa powder
  • ½ teaspoon espresso powder or instant coffee
  • 1 teaspoon vanilla extract


  • Preheat oven to 375°F. Grease and flour the bottom and all the way up the sides of an 8-inch cake pan. Use a parchment round or cut parchment to fit the bottom of the cake pan and then grease and flour that.
  • Place eggs in a small bowl and whisk to lightly beat them. This is just to break up the yolks so it’s easier to mix into the cake batter. Set aside.
  • We’re going to melt the chocolate over a double boiler. Fill a small or medium saucepan with 2-3 inches of water. Cover and bring to a boil over medium heat.
  • Break up the baking chocolate and add it to a large heat-safe bowl (be sure your bowl will fit on top of the pan that’s boiling on the stove). Add the butter with the chocolate and place the bowl on top of the pot of boiling water. Be careful not to burn yourself and not to get any water into the chocolate mixture.
  • Reduce heat to medium low and stir almost constantly until the chocolate and butter and smooth and melted.
  • Remove from the heat and stir in the sugar.
  • Stir the eggs into the chocolate mixture and stir until the eggs are completely mixed in.
  • Add the instant espresso and vanilla; stir.
  • Place the cocoa in a sifter and sift it onto the cake batter. Stir until completely mix. Pour cake batter into prepared pan.
  • Bake for about 25 minutes, or until the top looks solid. Mine took 25 minutes exactly at every test, but know that ovens all bake differently.
  • Cool 5 minutes, then run a butter knife around the edge carefully to loosen. Invert serving plate over the cake pan and carefully flip over to remove the cake from the pan (be careful not to burn yourself). Remove pan and parchment. Allow cake to cool completely.
  • Store covered at room temperature for up to 4 days.
  • Serving suggestions: dust with powdered sugar and/or cocoa, serve with raspberries or whipped cream.



  • Do not substitute or change ingredients. This recipe is easy but can be finicky.
  • When choosing a serving plate make sure to choose one that is flat. Do not use a rimmed dinner plate that dips in the center or the cake will fall in the center as it cools and adjusts to the contours of the plate.
  • This cake is super rich so small slices are the way to go!
  • I do not recommend freezing this cake.
  • The outside will crumble a bit when you’re slicing but the center will be fudgy and rich.
