Ingredients
Scale
Cake
- 1 cup plus 1 1/2 tablespoons (250 grams) unsalted butter, at room temperature and cut into 3/4-inch cubes, plus extra for greasing
- 7 ounces (200 grams) dark chocolate (70% cocoa solids), chopped into 3/4-inch pieces
- 1 1/2 teaspoons instant coffee granules, dissolved in 1 1/2 cups (350 milliliters) boiling water
- 1 1/4 cups (250 grams) granulated sugar
- 2 large eggs, lightly beaten
- 2 teaspoons vanilla extract
- 1 3/4 cups plus 2 tablespoons (240 grams) self-rising flour
- 1/3 cup (30 grams) Dutch-processed cocoa powder, plus 1 1/2 teaspoons for dusting
- 1/4 teaspoon salt
Chocolate Ganache
- 7 ounces (200 grams) dark chocolate (70% cocoa solids), roughly chopped into 3/4-inch pieces
- 3/4 cup (180 milliliters) heavy cream
- 1 tablespoon light corn syrup
- 1 tablespoon unsalted butter, at room temperature
Espresso Cinnamon Mascarpone Cream
- 1 1/2 cups plus 1 tablespoon (375 milliliters) heavy cream
- 3/4 cup (190 grams) mascarpone cheese
- Scraped seeds of 1/2 vanilla pod
- 2 1/2 teaspoons finely ground espresso
- 3/4 teaspoon ground cinnamon
- 2 1/2 tablespoons confectioners’ sugar
Instructions
- Prepare the Oven and Pan: Preheat your oven to 350°F (170°C). Grease a 9-inch (23 cm) round springform pan with butter, then line it with parchment paper. Set aside for later use.
- Make the Cake Batter: In a large heatproof bowl, combine the butter, chopped dark chocolate, and the hot coffee mixture. Stir well until everything melts and the mixture is smooth. Whisk in the sugar by hand until fully dissolved. Add the beaten eggs and vanilla extract, whisking thoroughly until the batter is smooth and combined. In a separate bowl, sift together self-rising flour, Dutch-processed cocoa powder, and salt. Gradually whisk these dry ingredients into the wet chocolate mixture. The batter will be noticeably liquid—this is expected for this recipe.
- Bake the Cake: Pour the batter into the prepared springform pan. Place in the oven and bake for about 1 hour, or until a skewer inserted into the center comes out clean or with just a few dry crumbs. The cake’s top will crack and form a crust, which is normal. Let the cake cool in the pan for 20 minutes, then carefully remove it from the pan. Allow it to cool completely on a wire rack.
- Prepare the Chocolate Ganache: If you wish to use ganache, place the chopped chocolate in a food processor and process until finely chopped; set aside. In a small saucepan, combine heavy cream and light corn syrup and heat over medium-high heat until bubbles just start to appear, just before boiling. Remove from heat and, with the food processor running, pour the hot cream mixture slowly over the chopped chocolate. Process for 10 seconds, then add the butter. Continue processing until the ganache is shiny and completely smooth. Alternatively, this can be done by hand by stirring the chopped chocolate with hot cream until nearly melted, then stirring in butter until smooth.
- Set the Ganache: Scrape the ganache into a bowl and cover with plastic wrap pressed directly onto its surface to prevent a skin from forming. Allow the ganache to set to desired consistency: pour liquid for a thin, glossy coating or leave at room temperature about 2 hours for a thicker spreadable consistency. Ganache can be stored at room temperature for up to 3 days, refrigerated for 2 weeks, or frozen (noting some loss of shine after thawing).
- Make the Espresso Cinnamon Mascarpone Cream: In the bowl of an electric mixer fitted with a whisk attachment, combine heavy cream, mascarpone, vanilla seeds, espresso, ground cinnamon, and confectioners’ sugar. Beat on medium-high speed for 1 to 2 minutes until soft peaks form, creating a light, fluffy cream.
- Assemble and Serve: Remove parchment paper from the cooled cake and discard. Transfer the cake to a serving plate. Spread the prepared ganache evenly over the top if using. Slice the cake into wedges and serve with the espresso cinnamon mascarpone cream on the side. The cake can be stored in an airtight container and will keep well for 4 to 5 days, with or without the ganache and cream.
Notes
- Use high-quality dark chocolate with at least 70% cocoa solids for the best flavor and texture.
- The cake batter is intentionally liquid; do not add extra flour or change the proportions.
- Self-rising flour contains baking powder and salt; if unavailable, use all-purpose flour with added 1 1/2 teaspoons baking powder and 1/4 teaspoon salt.
- The instant coffee enhances the chocolate flavor but does not overpower the cake.
- Ganache can be made ahead and stored, but bring to room temperature before using for easy spreading.
- The espresso cinnamon mascarpone cream adds a complementary lightness and depth but can be omitted if desired.
- Store the cake in an airtight container to maintain moisture for up to 5 days.
