การเตรียมการ
1Preheat the oven to 350°F (180°C). Grease the cake pan and dust with flour.
2In an electric mixer with whisk attachment, or using a large bowl and a hand mixer, whisk together the eggs and sugar for at least 5 minutes, until they are thick, pale, and at least doubled in volume.
3Sift the flour and carefully fold it into the mixture. Fold in the vanilla, lemon zest, and butter.
4Put the batter into the cake pan and bake immediately for 40 minutes, or until the top is springy and a skewer inserted into the middle of the cake comes out clean.
5Leave the cake to cool in the pan for a few minutes, then turn out and leave to cool completely on a wire rack.
6When the cake is cold, cut it very carefully horizontally into three equal pieces, using a serrated bread knife.
7In a large bowl, whip the cream until stiff. Crush the raspberries lightly with the confectioner’s sugar and fold into the cream, leaving behind any juice so that the cream is not too wet.
8Spread half the cream and raspberry mixture onto one piece of the cake, and top with a second piece. Spread the remaining cream mixture on to the second layer of cake and top with the final layer. Dust the cake with confectioner’s sugar and serve immediately.
