This section provides a quick rundown of the ingredients used in this small flourless chocolate cake recipe. For complete measurements and step-by-step instructions, please scroll to the recipe card located at the bottom of this post.

  • Chocolate: Choose high-quality chocolate like Guittard, Ghirardelli, or Hershey’s chocolate chips, or Baker’s brand semi-sweet chocolate, as it’s the main ingredient.
  • Butter: Salted butter is preferred, though unsalted works too.
  • Oil: Use vegetable, canola, or avocado oil. Either of these oils mixed with melted butter, enhances the chocolate’s silkiness and smoothness.
  • Egg: Incorporate 1 large egg and 1 egg white for a moist, fudgy texture. Save the extra egg yolk and use it in any of our egg yolk recipes like a small batch of Chocolate Scones or Chocolate Chip Cookies.
  • Unsweetened cocoa powder: Cocoa powder helps take the place of flour in this recipe. Consider using leftover cocoa powder in a mini Chocolate Pie, a small batch of rum balls, or Chocolate Banana Bread.
  • Vanilla extract, salt, and sugar: Sugar and vanilla sweeten the cake and add flavor. Sugar also adds moisture and helps give the cake a great texture. Salt enhances the flavors of the other ingredients.

How To Make A Flourless Chocolate Cake

These step-by-step photos and instructions help you visualize how to make a mini flourless chocolate cake. See the recipe box below for ingredient amounts and full recipe instructions.

  1. Preheat the oven to 350°F (177°C). Lightly butter a 5×7-inch baking dish, a 5×5-inch baking dish, or a 4×6-inch baking dish, and set the dish aside.
  2. Combine chocolate chips, butter, and oil in a heatproof bowl over a pot of simmering water and heat, stirring often, until the chocolate has melted and the mixture is smooth. Remove the bowl from the saucepan and set it aside to cool.

Pro Tip: Melting chocolate using a double boiler, which is a bowl set over a pot of barely simmering water, is highly effective. This method lets you monitor the melting process, preventing burning. The steam gently melts the chocolate, and the addition of oil and butter ensures it melts smoothly.

  1. In a small bowl, whisk together the egg, cocoa powder, vanilla, and salt. Gradually whisk into the cooled melted chocolate. Set the bowl aside.

  1. In another small bowl, beat the egg white and sugar together until stiff peaks form.

Pro Tip: Stiff peaks occur when you lift your beater and observe a peak that stands upright in the bowl without collapsing.

  1. Bake the cake for 25 to 30 minutes.

Pro Tip: While baking, the cake will rise, but due to the lack of gluten, it lacks the structure to maintain that rise after being removed from the oven. As it cools, the air bubbles inside contract, causing the cake to sink back down. It’s normal for the top to crack slightly, as you can see in the recipe’s accompanying photographs.

  2. Enjoy the cake as-is, or add a dollop of whipped cream, vanilla ice cream, or chocolate ganache (see recipe below).

Simple Ganache Recipe (Optional Topping)

Ganache, a blend of chocolate and warm cream, is surprisingly simple to make and a delightful yet optional topping for the flourless chocolate cake. Here’s how to make it:

  1. Place 1/4 cup of high-quality chocolate chips or chopped chocolate in a small bowl.
  2. Heat 1/4 cup of heavy cream in a saucepan on medium-low until it simmers, or in the microwave until it bubbles. Avoid boiling over.
  3. Let the hot cream sit over the chocolate for 2-3 minutes, then gently stir until smooth.
  4. Drizzle the ganache over your cake for an extra touch of richness.

Tip: Double the recipe for more ganache.

Expert Tips

  • Choose the Right Baking Dish: Success hinges on using the correct baking dish. Recommended sizes are a 5×7-inch dish, a 4×6-inch dish, or a 5×5-inch dish.
  • Use a Rimmed Baking Sheet: Since the cake rises significantly, placing the baking dish on a baking sheet helps catch any spills.
  • Avoid Overbaking: Typically, it bakes in 25-30 minutes. It’s ready when the top has a matte crust and the center is just set. A toothpick test (clean removal indicates doneness) can also be used.
  • Enhance Your Topping: Beyond a simple powdered sugar dusting, try adding a bit of cinnamon or nutmeg to the sugar for extra flavor.
