📝 About This Recipe

Indulge in a dessert that marries the intensity of a French truffle with the elegance of a classic torte, all while remaining perfectly keto-friendly. This cake relies on high-quality fats and premium cocoa to achieve a fudgy, melt-in-your-mouth texture that defies its low-carb status. It is the ultimate centerpiece for any celebration, offering a sophisticated bitterness balanced by a whisper of vanilla and a silky smooth finish.

🥗 Ingredients

The Chocolate Base

  • 8 ounces Sugar-free dark chocolate chips (at least 70% cocoa equivalent)
  • 1 cup Unsalted grass-fed butter (cubed, at room temperature)
  • 1 teaspoon Espresso powder (to enhance the chocolate flavor)
  • 1 tablespoon Pure vanilla extract

The Batter Structure

  • 3 pieces Large eggs (at room temperature)
  • 3/4 cup Granulated Erythritol or Monk Fruit sweetener (powdered version preferred for texture)
  • 1/2 cup Unsweetened cocoa powder (Dutch-processed for a deeper color)
  • 1/4 teaspoon Sea salt (fine grain)

Silky Chocolate Ganache Topping

  • 4 ounces Sugar-free dark chocolate (finely chopped)
  • 1/2 cup Heavy whipping cream
  • 2-3 drops Stevia glycerite (optional, for added sweetness)

Garnish

  • 1/2 cup Fresh raspberries
  • 4-5 pieces Fresh mint leaves
  • 1 pinch Flaky sea salt (for finishing)

👨‍🍳 Instructions

  1. 1

    Preheat your oven to 375°F (190°C). Grease an 8-inch springform pan generously with butter and line the bottom with a circle of parchment paper.

  2. 2

    In a microwave-safe bowl or using a double boiler, combine the 8 ounces of chocolate chips and the cubed butter. Melt in 30-second increments, stirring in between until completely smooth.

  3. 3

    Whisk the espresso powder and vanilla extract into the melted chocolate mixture. Set aside to cool slightly so it doesn't scramble the eggs later.

  4. 4

    In a separate large mixing bowl, beat the eggs and the granulated sweetener together using a hand mixer on medium-high speed for about 3-5 minutes. The mixture should become pale and double in volume.

  5. 5

    Gently fold the cooled chocolate-butter mixture into the aerated eggs using a silicone spatula. Use a light hand to maintain the air bubbles.

  6. 6

    Sift the cocoa powder and sea salt over the wet ingredients. Sifting is crucial to avoid any dry lumps in this flourless batter.

  7. 7

    Continue folding gently until no streaks of cocoa remain and the batter is a uniform, glossy dark brown.

  8. 8

    Pour the batter into the prepared springform pan and smooth the top with your spatula. Tap the pan firmly on the counter once to release large air pockets.

  9. 9

    Bake for 35-40 minutes. The edges should be set and the center should remain slightly soft to the touch (it will firm up as it cools).

  10. 10

    Remove the cake from the oven and let it cool in the pan for at least 15 minutes before carefully releasing the springform sides.

  11. 11

    While the cake cools, prepare the ganache: Heat the heavy cream until it just begins to simmer, then pour it over the 4 ounces of chopped chocolate. Let sit for 2 minutes, then whisk until glossy.

  12. 12

    Pour the ganache over the center of the cooled cake, allowing it to drip naturally down the sides. Top with fresh raspberries and a pinch of flaky salt.

💡 Chef's Tips

Use room temperature eggs to ensure they whip to maximum volume for a lighter cake texture. If your sweetener feels gritty, pulse it in a blender for 30 seconds to create a 'powdered' version that dissolves instantly. Do not overbake! A flourless cake continues to cook after it leaves the oven; the center should still have a slight jiggle. For the cleanest slices, dip a sharp knife in hot water and wipe it dry between every single cut. If you are sensitive to the cooling effect of Erythritol, try a blend of Monk Fruit and Allulose for a more natural sugar taste.

🍽️ Serving Suggestions

Serve with a dollop of unsweetened whipped cream infused with a touch of cinnamon. Pair a slice with a glass of dry red wine, such as a Cabernet Sauvignon, to complement the dark cocoa. Enjoy alongside a hot cup of black coffee or a double shot of espresso. Add a side of sugar-free vanilla bean ice cream for a classic 'à la mode' experience. Lightly dust with extra cocoa powder just before serving for a professional, matte finish.
