Jubilee cake

Method

• step 1

  Make the frosted rose petals the day before. Separate the petals and spread the caster sugar over a plate. Holding one petal at a time, lightly paint both sides with egg white. Spoon sugar over it, then using tweezers, shake off the excess. Dry on baking parchment for a day.

• step 2

  Preheat the oven to 180C/gas 4/fan 160C. Butter two 20cm/8in round sandwich tins and line their bases with baking parchment. Tip the sugar into a mixing bowl and add the softened butter. Beat for a minute or so until pale and fluffy, then beat in the egg yolks.

• step 3

  Sift the flour and baking powder over the cake mixture. Fold in as lightly as you can using a large metal spoon, then fold in the almonds and extract. Stop folding as soon as the flour traces have gone.

• step 4

  Whisk the egg whites until they just hold their shape. Gently fold a third of the egg white into the cake mix, using the whisk. Repeat with another third, then the final third. Take care not to over-mix and lose the lightness of the egg whites.

• step 5

  Lightly fold in the raspberries. Divide between the prepared tins and level the mixture using a round-bladed knife. Bake for 30-35 minutes. Cool in the tin for 5 minutes, then turn out, peel off the lining paper and leave to cool completely.

• step 6

  Set one cake on a serving plate or cake stand. Spoon the cream on to the cake with a dessertspoon. Scatter the raspberries over and put the other cake on top. Blend the icing sugar with 1-11⁄2 tbsp cold water until it is smooth and coats the back of a spoon thinly. Drizzle the icing over the cake. Scatter the rose petals over and around the cake, dust with icing sugar and serve.
