Passion fruit and coconut layer cake
British 45 Mins Prep · 80 Mins Cook
- Preheat the oven to 180°C, gas mark 4. Butter 4 x 20cm cake tins and line the tins with baking paper. Bring six eggs to room temperature.
- To make the cake, combine the six eggs, sugar and vanilla in the bowl of a stand mixer. Beat on high until the mixture nearly triples in volume, approx. 7-10 minutes.
- With the mixer on, slowly stream in the oil until well mixed.
- In a medium-sized bowl, whisk the flour and salt together.
- Gently fold the flour mixture into the egg mixture until well mixed. (You may need to transfer the egg mixture to a large mixing bowl to do this, and it’s always best to use a big, wide bowl when folding ingredients together to lower your chances of deflating the batter too much.)
- Divide the batter between the tins and tap them lightly on the counter to remove any large bubbles.
- Bake the cakes until golden and a toothpick inserted into the centre comes out clean, 20-25 minutes. Let the cakes cool in their tins, on a rack, until cool to the touch, then turn them out onto the rack, and remove the parchment. Let cool completely.
- To make the syrup, combine the coconut milk and sugar in a small saucepan over a medium heat. Cook until the sugar dissolves then stir in the desiccated coconut. Let the mixture cool completely before using.
- To make the buttercream, separate five egg yolks from the whites.
- Combine the egg whites and sugar in a glass or stainless-steel bowl set over a pan of simmering water. Whisk the mixture constantly until the sugar dissolves and is hot to the touch.
- Remove from the heat and whip on a high speed until light and fluffy and the meringue has cooled to room temperature. Scoop into a piping bag fitted with a large straight nozzle.
- Turn the mixer down to a medium and add the butter, 1 tbsp at a time, until all the butter is incorporated. If the buttercream curdles at any point, turn the mixer up to high and whip until it emulsifies. Add the extracts and a pinch of salt.
- To make the passion fruit curd, place the 5 egg yolks, cornstarch, sugar, passion fruit pulp and lemon juice in a medium-sized saucepan over a medium heat. Cook, stirring, for 2 minutes, or until the sugar has dissolved.
- Gradually add the butter, stirring continuously, until melted. Reduce the heat to low and cook for a further 6-8 minutes, or until the curd has thickened. Allow to cool.
- To assemble the cake, place one layer of cake on a serving plate or cake stand. Brush with the syrup and spread 1⁄3 of the syrup-moistened coconut over the top.
- Pipe a ring of buttercream along the edge of the cake and spread a layer of passion fruit curd in the centre. Repeat this process with the rest of the cake layers.
- Spread the remaining buttercream over the cake, smooth the top.
- Place the 200g of desiccated coconut in a pan over medium heat and toast until golden brown. Allow to cool completely. Press the toasted desiccated coconut into the sides.
- Slice and serve with BRW Society Mango Madness or Coconut Chai tea.
