Why You Must Make

  • Do you remember your first taste of a flourless chocolate cake? It was pretty amazing, wasn’t it? That’s why this is a must-make dessert!
  • The absence of flour makes the cake consistency more fudgy than cakey.
  • It’s baked in a water bath for the silkiest results.
  • Kahlua, a coffee liqueur, brings out the chocolate flavor without any hint of an alcohol flavor.

Ingredient Notes

  • Semisweet and Unsweetened Chocolate – I used 4-ounce Ghirardelli bars. They’re better quality than chocolate chips and can be found at most supermarkets
  • Butter – I use salted butter and adjust the salt in the recipe to compensate. I steer away from generic butter as it usually has a larger water content which may affect the recipe.
  • Kahlua – A coffee liqueur. May substitute another coffee liqueur, coffee or espresso. Espresso will give a more pronounced coffee flavor.
  • Brown Sugar – I use light brown sugar, but dark will work, too.
  • Eggs – All my recipes use large eggs unless otherwise noted. When baking with eggs, pull them out of the refrigerator an hour or so before baking to take the chill off. This will help them incorporate into the batter more easily.

Expert Tips

  • Wrap your springform pan with a double layer of foil. This will prevent any water from seeping into the springform pan while the cake is baking.
  • Melt your chocolate with the butter in a microwave-safe bowl. Use 30-second intervals, stopping to stir before restarting, until melted. If there are a few small pieces of chocolate that haven’t completely melted, the residual heat should finish it off. Just stir until smooth.
  • You will be baking your cake in a bain marie, or a water bath. This provides a stable temperature for the cake to bake. I use a roasting pan filled with a few inches of water for mine.
  • The top of the cake will be just set when the cake is done. Check with a toothpick. You should not see batter when you pull out the toothpick, but a few moist crumbs are OK>
