Recipe Tips for Making the Best Flourless Chocolate Cake
- Since this cake is flourless, it delivers pure chocolate flavor. Opt for high-quality chocolate bars rather than chocolate chips. If you can find European brands, don’t hesitate to try them out.
- PRO Tip: For domestic chocolate, I often use Ghirardelli bars. Keep an eye out for sales during the holidays to stock your pantry!
- PRO Tip: Consider using European butter. For instance, Kerrygold Irish Butter offers a richer flavor due to its higher butterfat content, making it a fantastic choice if you’re looking for an upgrade.
- Make sure to read the recipe thoroughly; some so-called flourless cakes sneak in a couple of tablespoons of flour, which is a no-go for gluten-free guests or Passover meals.
- A splash of coffee enhances the depth of chocolate flavor without adding any coffee notes to the cake.
- If you’re a chocolate lover, consider using bittersweet chocolate for a more intense flavor.
- This recipe incorporates whipped egg whites folded into the chocolate mixture for a delightfully airy texture. The remaining egg whites are what we’ll transform into our marshmallow frosting!
- PRO Tip: When making meringue, ensure that all bowls and utensils are free from grease. Any residue can prevent the egg whites from whipping up perfectly.
- PRO Tip: I recommend separating your eggs one at a time in different bowls. This way, if you accidentally mix a yolk with your whites, you won’t spoil the entire batch!
Ingredients
For the Cake:
- 2½ sticks of butter, cut into pieces, plus more for the pan
- 6 ounces semisweet chocolate, chopped
- 6 ounces unsweetened chocolate, chopped
- 6 large eggs
- ¾ cup light brown sugar
- A pinch of salt
- ½ cup hot coffee plus 1 tsp vanilla
For the Meringue and Chocolate Drizzle:
- 2 ounces semisweet chocolate, chopped
- 2 tablespoons unsalted butter
- 1 tablespoon light corn syrup
- 1 cup granulated sugar
- 3 large egg whites
- ¼ teaspoon cream of tartar
- A pinch of salt
- 2 teaspoons vanilla extract
Instructions
- Preheat your oven to 325°F (160°C).
- Butter a 9-inch springform pan’s bottom and sides, then line the bottom with parchment paper.
- In the top of a double boiler, melt the semisweet and unsweetened chocolate over low heat, stirring until smooth.
- In a mixing bowl, add the eggs, brown sugar, and salt.
- Place the mixing bowl over the simmering water to gently warm the mixture for about two minutes, whisking continuously.
- Transfer the bowl to a stand mixer and beat on medium speed for about 5 minutes until the mixture is thick and light.
- On low speed, incorporate the coffee and vanilla, followed by the melted chocolate.
- Gradually add the butter, mixing until combined.
- Pour the batter into the prepared pan and bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out with just a few crumbs.
- Let the cake cool, then run a knife around the edge and release the springform.
- For the chocolate drizzle, microwave the semisweet chocolate, butter, and corn syrup until melted. Set aside to cool slightly.
- To prepare the meringue, whisk together the sugar, egg whites, cream of tartar, salt, and ⅓ cup water in the top of the double boiler over simmering water.
- Using a handheld mixer, beat the mixture on low, gradually increasing to high until soft peaks form, which should take about 5 minutes.
- Remove from heat and continue whisking until stiff peaks form.
- Spread the meringue on top of the cooled cake, creating peaks with a fork or an offset spatula. Finish by drizzling the melted chocolate over the top.
