Ingredients
  

For the Cake
  • 10 oz dark chocolate (60-70% cacao), finely chopped
  • 1/2 cup unsalted butter cut into cubes
  • 1 cup granulated sugar divided
  • 1/4 cup unsweetened cocoa powder sifted
  • 6 large eggs separated (whites and yolks)
  • 1 tsp pure vanilla extract
  • 1/4 tsp salt
For the Chocolate Ganache (Optional)
  • 1/2 cup heavy cream
  • 4 oz dark chocolate (60-70% cacao), finely chopped or chips

Equipment

  • 8-inch round springform pan
  • Large heatproof bowl
  • Small saucepan
  • Whisk
  • Rubber Spatula
  • Electric Mixer
  • Parchment Paper

Method
 

Preparation
  1. Preheat oven to 325°F (160°C). Grease an 8-inch (20cm) springform pan, line the bottom with parchment paper, and grease the parchment. Set aside.
  2. In a large heatproof bowl set over a saucepan of simmering water (bain-marie), melt the chopped dark chocolate and butter, stirring occasionally until smooth. Remove from heat and let cool slightly.
  3. In a separate medium bowl, whisk together the egg yolks, 1/2 cup (100g) of the granulated sugar, sifted cocoa powder, vanilla extract, and salt until smooth and well combined.
  4. Gradually whisk the slightly cooled chocolate mixture into the egg yolk mixture until fully incorporated and smooth.
  5. In a very clean, dry bowl (preferably metal or glass) using an electric mixer, beat the egg whites on medium speed until soft peaks form. Gradually add the remaining 1/2 cup (100g) granulated sugar, increasing speed to high, and continue beating until stiff, glossy peaks form. Be careful not to overbeat.
  6. Gently fold one-third of the whipped egg whites into the chocolate mixture to lighten it. Then, carefully fold in the remaining egg whites in two additions, taking care not to deflate the mixture. Mix just until no white streaks remain.
Baking & Cooling
  1. Pour the batter into the prepared springform pan. Bake for 30-35 minutes, or until the edges are set and a toothpick inserted into the center comes out with moist crumbs (not wet batter). The center may still be slightly jiggly, which is good for a fudgy texture.
  2. Remove the cake from the oven and let it cool completely in the pan on a wire rack. As it cools, the center will slightly sink and crack, which is normal for a flourless cake. Once cool, run a knife around the edges before releasing from the springform pan.
Optional Ganache
  1. While the cake cools, prepare the ganache if using. Heat heavy cream in a small saucepan over medium heat until it just begins to simmer. Remove from heat and pour over the chopped dark chocolate in a heatproof bowl. Let sit for 5 minutes, then whisk until smooth and glossy.
  2. Pour the slightly cooled ganache over the completely cooled cake, spreading evenly. Let the ganache set slightly at room temperature or in the refrigerator for 15-30 minutes before slicing and serving.

Notes

For best results, use high-quality dark chocolate (around 60-70% cacao) for a richer flavor. This cake is best served at room temperature. Store leftovers covered in the refrigerator for up to 5 days; bring to room temperature before serving for the optimal fudgy texture.

Pro Tips for Making This Fudgy Flourless Chocolate Cake

Achieving that perfect, deeply fudgy texture with a gorgeous crackly top on your Fudgy Flourless Chocolate Cake is simpler than you might think, especially with a few tricks I’ve learned over the years.

  • My Secret Trick: I always line the bottom of my springform pan with parchment paper and grease the sides thoroughly. This ensures a clean release and that beautiful, defined edge every single time.
  • Don’t overmix the batter once the eggs are added! Gentle folding is key to keeping the cake dense and fudgy, preventing too much air from incorporating, which can make it more cake-like than brownie-like.
  • Keep an eye on the baking time. This cake is done when the edges are set and a crackly crust has formed, but the center still has a slight wobble. This slight under-baking is what guarantees that wonderfully moist, fudgy interior we all adore in a Fudgy Flourless Chocolate Cake.
  • Allow the cake to cool completely in the pan on a wire rack. This is crucial for the cake to set properly and prevent it from cracking excessively when you remove it. Patience truly pays off here!

Fun Variations for Fudgy Flourless Chocolate Cake

One of the things I love most about baking is the joy of personalizing a recipe, and this Fudgy Flourless Chocolate Cake is a wonderful canvas for creativity! Here are a few ways to add your own special touch.

Zesty Orange Twist

For a bright contrast to the rich chocolate, I sometimes add 1-2 teaspoons of orange zest to the batter. My friend, Clara, adores this combination, saying it reminds her of those decadent chocolate oranges from her childhood. It adds a lovely aromatic lift!

Berry Bliss

Swirl in a handful of fresh raspberries or dried cranberries into the batter just before baking for pockets of fruity tartness. This is a delightful addition, especially when berries are in season. Or, if you’re making the ganache, a few drops of raspberry extract can give it a lovely subtle flavor.

Spiced for Comfort

For a cozy, warm twist, try adding a pinch of cinnamon or a tiny dash of cayenne pepper to the cocoa powder. It won’t make it spicy, but it will enhance the chocolate’s depth in a surprising way. It’s like a secret hug in every bite!

What to Serve With Fudgy Flourless Chocolate Cake

When it comes to enjoying a slice of this magnificent Fudgy Flourless Chocolate Cake, the accompaniments can truly elevate the experience! While it’s absolutely sublime on its own, a few simple additions can make it feel like an even grander occasion.

I often serve it with a generous scoop of vanilla bean ice cream; the cool creaminess is a perfect counterpoint to the warm, fudgy cake. For something a little lighter, a scattering of fresh berries like raspberries or strawberries adds a beautiful pop of color and tartness, making each bite feel fresh. My mom always insists on a strong cup of black coffee or a delicate Earl Grey tea to balance the richness, especially after dinner. For a quick and easy presentation, a simple dusting of powdered sugar is always elegant, or a dollop of freshly whipped cream can never go wrong!

How to Store Fudgy Flourless Chocolate Cake

Knowing how to properly store your Fudgy Flourless Chocolate Cake means you can savor its deliciousness for days, ensuring every slice tastes as fresh as the first.

Keeping it Fresh in the Fridge

Once cooled, this cake can be stored in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. I always prefer the fridge, as it helps maintain that lovely fudgy texture. If it’s chilled, just let it come to room temperature for about 30 minutes before serving, or warm a slice slightly in the microwave for that gooey, fresh-baked feel.

Freezing for Later Enjoyment

This cake freezes beautifully! Wrap individual slices or the entire cooled cake tightly in plastic wrap, then again in aluminum foil. It will keep well in the freezer for up to 3 months. When you’re ready for a treat, simply thaw it in the refrigerator overnight, and then bring it to room temperature or gently warm it before serving. My personal tip for reheating is a quick 15-second zap in the microwave; it makes the center perfectly molten again!

Nutritional Benefits

Indulging in a slice of Fudgy Flourless Chocolate Cake can be a delightful treat, offering more than just satisfaction. Made with dark chocolate, it provides antioxidants, and the eggs contribute protein, making it a surprisingly wholesome dessert that combines indulgence with simple, nourishing ingredients.
