Čokoladna torta sa kremom od maslaca i kave/Chocolate cake with espresso buttercream

SCROLL DOWN FOR ENGLISH VERSION
Ova torta mi je odmah privukla pažnju kad sam ju vidjela na blogu My baking adiction, jer volim kolače i torte koje imaju puno slojeva, a i zbog kontrasta bijele kreme i tamnog biskvita. Kad je Ljilja sa bloga Chocolate dust odabrala kavu kao temu za ovaj mjesec, nisam više čekala ni sekunde jer nije bilo boljeg povoda da ju napravim obzirom da je ona bila i rođendanska torta za mog dragog i moja ulaznica za ovomjesečnu igru. Vrlo je jednostavna za napraviti, jako lijepo izgleda i svi su bili oduševljeni okusom. Inače obožavam kavu, svakodnevno je neizostavni dio mog jutarnjeg rituala, volim njen miris i okus u desertima i kolačima. Ako ikad zatrebate čokoladnu bombu toplo preporučujem ovaj recept, a original se nalazi na oprah.com stranici.

Sastojci za biskvit:

300 g šećera

170 g brašna

85 g kakaa u prahu

1 žličica praška za pecivo

1 žličica sode

3/4 žličice soli

2 jaja

180 ml mlijeka

6 žlica ulja

2 žličice esencije vanilije

180 ml vruće vode

Krema od maslaca i kave
4 žumanjka

150 g šećera

60 ml vode

230 g omekšalog maslaca

2 žličice kave

1 žlica vruće vode

Ganache krema

340 g tamne čokolade (ja sam koristila mliječnu kuverturu), u komadićima
60 g maslaca narezanog na komadiće

240 ml slatkog vrhnja za šlag

1 žlica šećera

BISKVIT

Pećnicu zagrijte na 180 stupnjeva. Pleh 40 x 25 cm obložite pek papirom. U većoj posudi promiješajte šećer, brašno, kakao, prašak za pecivo, sodu i sol. U drugoj posudi mikserom izmješajte jaja, mlijeko, ulje i vaniliju. Postepeno dodavajte smjesu od jaja u smjesu od brašna i miksajte 5 minuta. Smanjite mikser i dodajte vruću vodu i miješajte dok se sve ne ujednači. Smjesu prebacite u pleh, poravnajte i pecite 20 do 25 minuta. Ostavite da se skroz ohladi i prerežite biskvit na tri jednaka dijela.

KREMA OD MASLACA I KAVE

Na srednjoj brzini miksajte žumanjke 5 minuta. U međuvremenu u manjoj posudi promiješajte šećer i 60 ml vode, stavite na srednju vatru i kuhajte dok se sav šećer ne otopi, i dok smjesa ne zakuha. Pojačajte vatru i kuhajte sirup dok ne dosegne temperaturu od 115 stupnjeva. Sirup odmah dodajte žumanjcima u tankom mlazu. Smjesu miksajte dok se skroz ne ohladi, oko 10 minuta. Postepeno dodavajte žlicu po žlicu maslaca i miksajte dok ne dobijete jednoličnu smjesu. U šalici promiješajte kavu s vrućom vodom i umiksajte u smjesu.

Kremu ravomjerno raspodijelite na dva jednaka dijela, stavite prvi biskvit na tanjur, premažite ga sa pola kreme, stavite drugi biskvit na kremu i na njega nanesite ostatak kreme.

GANACHE KREMA U veću posudu stavite maslac i komadiće čokolade. U drugoj posudi promiješajte vrhnje za kuhanje i šećer, kuhajte na srednjoj vatri do točke vrenja. Prelijte vruće vrhnje preko čokolade i maslaca i miješajte dok ne dobijete jednoličnu smjesu, (dok se sav maslac i čokolada ne istope), i dalje miješajte dok ne dobijete gustu kremu, oko 15 minuta. Ja sam kremu ostavila da se hladi i u međuvremenu sam ju svakih 10 tak promiješala. Kremom premažite cijelu tortu i stavite ju u hladnjak na sat vremena da se stisne.

CHOCOLATE CAKE WITH ESPRESSO BUTTERCREAM adapted from My baking addiction

ORIGIN RECIPE from My baking adiction
For the cake:
1 1/2 (300 g) cups sugar
1 1/3 (170 g) cups all-purpose flour
2/3 (85 g) cup unsweetened cocoa
1 teaspoon baking powder
1 teaspoon baking soda
3/4 teaspoon salt
2 large eggs
3/4 (180 ml) cup milk
6 tablespoons canola oil
2 teaspoons pure vanilla extract
3/4 (180 ml) cup very hot water

For the espresso buttercream
4 large egg yolks
3/4 (150 g) cup sugar
2 sticks (230 g) unsalted butter, softened
2 teaspoons instant espresso powder
1 teaspoon very hot water

Ganache
12 ounces (340 g) bittersweet chocolate, chopped
4 tablespoons (60 g) unsalted butter,softened and diced
1 cup (240 ml) heavy or whipping cream
1 tablespoon sugar

Cake Preheat oven to 375°F (180 C). Line a 15 1/2″ x 10 1/2″ (40 x 25 cm) jelly-roll pan with parchment paper, spray paper with nonstick cooking spray. In the bowl of an electric mixer fitted with a whisk attachment, combine sugar, flour, cocoa, baking powder, baking soda, and salt at medium speed until blended. In another bowl, whisk eggs, milk, oil, and vanilla. Gradually beat egg mixture into flour mixture, about 5 minutes. Shift mixer to low speed; add hot water until blended. Pour batter into pan. Bake until toothpick comes out of the center clean, 20 to 25 minutes. Cool cake completely.

Espresso buttercream In the bowl of an electric mixer fitted with a whisk attachment, beat egg yolks at medium speed until they become lemon colored and ribbon like when beaters are lifted, about 5 minutes. Meanwhile, in a small saucepan, combine sugar and 1/4 cup water. Cook over medium-low heat, swirling pan occasionally, until sugar completely dissolves and syrup just comes to a boil. Increase heat to high; boil syrup until it registers 238°F (150 C) on a candy thermometer. With the mixer on medium speed, immediately add syrup to beaten egg yolks in a thin, steady stream. Beat mixture until it cools to room temperature and is light and fluffy, about 10 minutes. Gradually add butter, 1 tablespoon at a time, until completely incorporated. In a cup, dissolve espresso powder in hot water; beat into buttercream.

Ganache
In a large bowl, combine chocolate and butter. In a small saucepan, heat cream and sugar over medium-high flame, stirring occasionally, until small bubbles appear around edge of pan. Pour hot cream over chocolate; stir until chocolate and butter melt and mixture is completely smooth. Cool, stirring occasionally, until thickened but not pasty, about 15 minutes.
Invert cake onto a large wire rack; peel off parchment paper. Invert cake again onto a large cutting board. With a serrated knife, cut cake into equal thirds.
Set a large wire rack over a sheet of waxed paper. Arrange one cake layer on rack; spread half of buttercream evenly over top. Add another cake layer; spread top with remaining buttercream. Place remaining cake layer on top.
Pour ganache over top of cake, spreading with a spatula so it coats the sides. If ganache does not cover sides completely, pour any excess that has collected on the waxed paper back into bowl and spread again. Refrigerate cake until ganache sets, about 1 hour. Use two large spatulas to transfer cake onto a serving plate.
