I never turn down an opportunity to bake a cake, so when my Supper Club got together last weekend I jumped at the chance to bring dessert. I wanted to try something new so I went with Dorie Greenspan's Tiramisu cake. Boozy and caffeinated? Perfect!
It wasn't complicated but there are several components to make so it is a bit time consuming. I also over estimated how much of the syrup would soak into the cake layers so I was pretty conservative. I could have easily used the entire recipe since the middle of the cake layers ended up a bit dry. Next time I would also double the frosting recipe. The marscapone espresso frosting was delicious, but there wasn't quite enough for my liking. But then again I like a little cake with my frosting so to others it may have been the perfect balance. I used the toffee chocolate espresso beans from Trader Joes to decorate, they're super yummy and add a nice crunch to the cake. Loved this cake and will definitely make again for a special occasion.
Baking: From My Home to Yours by Dorie Greenspan
For the cake layers:
2 cups cake flour
2 teaspoons baking powder
1/8 teaspoon baking soda
1/4 teaspoon salt
1 1/4 sticks (10 tablespoons) unsalted butter, room temperature
1 cup sugar
3 large eggs
1 large egg yolk
1 1/2 teaspoons pure vanilla extract
3/4 cup buttermilk
For the espresso extract:
2 tablespoons instant espresso powder
2 tablespoons boiling water
For the espresso syrup:
1/2 cup water
1/3 cup sugar
1 tablespoon amaretto, Kahlua, or brandy
For the filling and frosting:
1 8-ounce container mascarpone
1/2 cup confectioners’ sugar, sifted
1 1/2 teaspoons pure vanilla extract
1 tablespoon amaretto, Kahlua, or brandy 1 cup cold heavy cream
2 1/2 ounces bittersweet or semisweet chocolate, finely chopped, or about 1/2 cup store-bought mini chocolate chips
Chocolate-covered espresso beans, for decoration (optional)
Cocoa powder, for dusting
Center a rack in the oven and preheat the oven to 350 degrees F. Butter two 9×2 inch round cake pans, dust the insides with flour, tap out the excess, and line the bottoms of the pans with parchment or wax paper. Put the pans on a baking sheet.
To make the cake:
Sift together the cake flour, baking powder, baking soda, and salt.
Working with a stand mixer, preferably fitted with a paddle attachment, or with a hand mixer in a large bowl, beat the butter on medium speed until soft and creamy. Add the sugar and beat for another 3 minutes. Add the eggs one by one, and then the yolk, beating for 1 minute after each addition. Beat in the vanilla; don’t be concerned if the mixture looks curdled. Reduce the mixer speed to low and add the dry ingredients alternately with the buttermilk, adding the dry ingredients in 3 additions and the milk in 2 (begin and end with the dry ingredients); scrape down the sides of the bowl as needed and mix only until the ingredients disappear into the batter. Divide the batter evenly between the two pans and smooth the tops with a rubber spatula.
Bake for 28 to 30 minutes, rotating the pans at the midway point. When fully baked, the cakes will be golden and springy to the touch and a thin knife inserted into the centers will come out clean. Transfer the cakes to a rack and cool for about 5 minutes, then run a knife around the sides of the cakes, unmold them, and peel off the paper liners. Invert and cool to room temperature right-side up.
To make the extract:
Stir the espresso powder and boiling water together in a small cup until blended. Set aside.
To make the syrup:
Stir the water and sugar together in a small saucepan and bring just to a boil. Pour the syrup into a small heatproof bowl and stir in 1 tablespoon of the espresso extract and the liqueur or brandy; set aside.
To make the filling and frosting:
Put the mascarpone, sugar, vanilla, and liqueur in a large bowl and whisk just until blended and smooth.
Working with the stand mixer with the whisk attachment or with a hand mixer, whip the heavy cream until it holds firm peaks. Switch to a rubber spatula and stir about one quarter of the whipped cream into the mascarpone. Fold in the rest of the whipped cream with a light touch.
To assemble the cake:
If the tops of the cake layers have crowned, use a long serrated knife and a gentle sawing motion to even them. Place one layer right-side up on a cardboard round or a cake plate protected with strips of wax or parchment paper. Using a pastry brush or a small spoon, soak the layer with about one third of the espresso syrup. Smooth some of the mascarpone cream over the layer – user about 1 1/4 cups – and gently press the chopped chocolate into the filling. Put the second cake layer on the counter and soak the top of it with half the remaining espresso syrup, then turn the layer over and position it, soaked side down, over the filling. Soak the top of the cake with the remaining syrup.
For the frosting, whisk 1 to 1 1/2 tablespoons of the remaining espresso extract into the remaining mascarpone filling. Taste the frosting as you go to decide how much extract you want to add. If the frosting looks as if it might be a little too soft to spread over the cake, press a piece of plastic wrap against its surface and refrigerate it for 15 minutes or so. Refrigerate the cake too.
With a long metal icing spatula, smooth the frosting around the sides of the cake and over the top. If you want to decorate the cake with chocolate-covered espresso beans, press them into the filling, making concentric circles of beans or just putting some beans in the center of the cake.
Refrigerate the cake for at least 3 hours (or for up to 1 day) before serving – the elements need time to meld.
Just before serving, dust the top of the cake with cocoa.
