An elegant and vibrant dessert featuring a moist pistachio-infused sponge layered with rich mascarpone cream and fresh raspberries. The combination of nutty pistachios, tart berries, and a hint of lime zest makes this a sophisticated centerpiece for any celebration.
Preheat your oven to 180°C (160°C fan/gas 4). Grease a 23cm springform cake tin with butter and line the base with parchment paper.
Place 150g of the pistachios into a food processor and pulse until they are finely ground. In a medium bowl, combine the ground pistachios with the plain flour, baking powder, and a pinch of salt.
In a separate large bowl, beat the softened butter and caster sugar together for about 5 minutes using an electric mixer until the mixture is pale and fluffy. Add the eggs one at a time, beating for 1 minute after each addition to ensure a light texture.
Stir in the vanilla extract, then gently fold in the flour and pistachio mixture using a large metal spoon or spatula, being careful not to overmix and deflate the batter.
Spoon the batter into the prepared tin and smooth the top. Bake for 35-40 minutes, or until a skewer inserted into the center comes out clean. Allow the cake to cool completely in the tin on a wire rack.
While the cake cools, prepare the frosting. Sift the icing sugar into a bowl, then add the mascarpone, double cream, and pistachio paste. Whisk until well combined and thick. Place in the fridge for 20-30 minutes to firm up to a spreadable consistency.
To assemble, use a serrated knife to carefully cut the cooled cake in half horizontally. Place the bottom layer on a serving plate and spread with a generous layer of the pistachio cream. Arrange half of the raspberries over the cream.
Place the second sponge layer on top. Cover the top and sides of the cake with the remaining cream. Decorate with the remaining raspberries, the rest of the chopped pistachios, and the lime zest. Serve chilled.
For the most vibrant green color, look for high-quality, unsweetened pistachio paste. If the mascarpone cream feels too soft after chilling, give it a brief whisk to stiffen it up before frosting. This cake is best served the day it's made but will keep well in the fridge for up to two days.
