Devil’s Food with Passion Fruit Truffle Filling

Ingredients:

1 and 3/4 cups all-purpose flour

1/3 cup dark or regular unsweetened cocoa powder

1 and 1/2 teaspoons baking powder

1 teaspoon baking soda

1/2 teaspoon salt

1/2 cup oil

1/4 cup unsalted butter, softened

1 cup granulated sugar

1 teaspoon vanilla extract

3 large eggs

1 cup semi-sweet chocolate chips, melted

1 cup buttermilk

Filling:

500g white chocolate, finely chopped

400g whipping cream

¼ cup (60ml) concentrated bottled passion fruit juice

To brush the cake:

½ tablespoon concentrated bottled passion fruit juice diluted in 4 tablespoons water

Frosting:

2/3 cup granulated sugar

1/3 cup all-purpose flour

3 tablespoons unsweetened cocoa powder

1/8 teaspoon salt

1 cup milk

1 cup unsalted butter, softened

1 cup semi-sweet chocolate chips, melted

Directions:

Preheat oven to 350 degrees F. Oil two 7.9inch (20cm) springform cake pan and line the bottom with baking paper.

Start by making the filling: place the cream in a saucepan and heat until it is nearly boiling. Remove from heat and add the chocolate all at once. Whisk until the chocolate is melted and the mixture is silky and smooth. Add the juice, mix well; refrigerate it, well covered, for 4-6 hours or until set.

To make the cake, in a medium sized mixing bowl, sift together flour, cocoa powder, baking powder, baking soda and salt.

In a large mixing bowl, using a mixer on medium speed, beat oil, butter, granulated sugar and vanilla, until creamy, about 2 minutes. Beat in eggs, one at a time, until well combined. Beat in 1 cup melted chocolate chips until combined. Reduce mixer speed to low and beat in flour mixture, alternating with buttermilk, until well combined, about 2-3 minutes.

Divide batter into pans. Bake 20-25 minutes, or until just set, and a toothpick inserted into cake comes out with moist crumbs attached. Cool for 5 minutes before transferring to wire racks to cool completely.

To make the frosting, in a small saucepan, whisk together sugar, flour, cocoa, salt and milk; bring to a boil, whisking frequently. Boil 1 minute or until thickened; remove pan from heat and strain mixture into a small bowl. Cool completely in the refrigerator or freezer.

Beat the butter until creamy, about 1 minute, in a large mixing bowl, using a mixer on medium speed. Beat in ?chocolate pudding? mixture until well combined, about 1 minute. Beat in melted chocolate until well combined and fluffy, about 2 minutes. Spread or pipe frosting on to cupcakes.

Assembling the cake: Line a baking sheet with parchment paper and place a wire rack over it. Using a serrated knife, cut each cake in half horizontally. (If necessary, shave off any uneven pieces of cake with a serrated knife so that it is smooth and even on all sides.) Brush the tops of three layers each with some of the juice. Place the bottom layer on a 9-inch round of cardboard and set it on the wire rack. Spread 1/3 the filling evenly on top of the layer. Top with a second layer of cake. Spread other 1/3 of filling evenly over it. Top with the third layer and spread the remaining filling. Top with the fourth layer. Chill in the refrigerator for 2 hours. Spread the entire cake with the chocolate frosting. Led to the refrigerator until serving time. Decorate as you like.
