Preheat the oven to 350℉ and grease and line one 9″ round springform pan. Coat the entire inside with a thin layer of nonstick spray, then cover the bottom with a round sheet of parchment paper and line the sides with additional strips of parchment paper.
Note: The cake will stick to the sides of the pan otherwise, so make sure the entire inside is covered in parchment paper.
In a microwave safe bowl, add the butter and chopped chocolate. Melt in 30 second intervals, stirring in between each, until smooth. Set aside.
¾ cup unsalted butter room temperature, 2 oz semi-sweet chocolate chopped
In a large mixing bowl, add the sugars and eggs. Whisk (using a hand mixer or by hand) vigorously for three minutes until frothy.
¾ cup granulated sugar, ½ cup light brown sugar packed, 3 large eggs
Pour in the cooled chocolate mixture and whisk until combined.
Sift in the dry ingredients and use a rubber spatula to mix it in until just combined.
½ cup all-purpose flour, ½ cup Dutch processed cocoa powder, ½ teaspoon kosher salt
Scrape the batter into the prepared springform pan, spread evenly, then bake for 25-30 minutes. Cool completely.
Lady Fingers
Mix together the espresso and sugar, then quickly dip and roll one lady finger at a time through the sweetened espresso.
¾ cups espresso, ¼ cup granulated sugar, 12 lady fingers
Lay the dipped lady fingers all over the top of the cake, ripping some apart so they fit in snugly.
Mascarpone Frosting
In the bowl of a stand mixer fitted with the whisk attachment (or with a hand mixer), add the mascarpone, powdered sugar, salt, and vanilla and whip on medium speed for 1 minute.
8 oz mascarpone, ½ cup powdered sugar, ¼ teaspoon kosher salt, 2 teaspoons vanilla
With the mixer running, slowly drizzle in the heavy cream and whip until the frosting becomes light and fluffy, about 1-2 minutes.
1 cup heavy whipping cream
Note: Overmixing can cause the frosting to curdle.
Swoop the frosting all over the top of the lady fingers, then refrigerate for at least 3 hours, but up to overnight.
