METHOD

  • 1

    Preheat the oven to 180°C, gas mark 4, and grease and line 3 x 20cm sandwich cake tins.

  • 2

    Using a stand mixer fitted with a paddle attachment, or a hand mixer, cream the butter and sugar until very light and fluffy – about 8 minutes.

  • 3

    Add the eggs one at a time, beating well in between each addition. Add the vanilla.

  • 4

    Sift the flour and bicarbonate of soda together and fold into the cake batter.

  • 5

    Divide the batter between 3 medium-sized bowls and stir the grated and puréed vegetables into each bowl (pea and courgette in one, butternut in the second and beetroot in the last bowl).

  • 6

    Spread each bowl of batter into a prepared cake tin and bake in the preheated oven for about 40 minutes or until a skewer inserted into the middle of the cakes comes out clean.

  • 7

    Allow the cakes to cool in the tins slightly, then remove and cool completely on a cooling rack.

  • 8

    To make the icing, preheat the oven to 200°C, gas mark 6, and bake the vanilla pod for 5 minutes or until completely dried. Allow to cool.

  • 9

    Blitz the dried vanilla pod in a food processor or blender until a fine powder forms.

  • 10

    Cream the icing sugar and butter until light and fluffy – about 8 minutes – then whip in the cream cheese, lime zest, lime juice and vanilla until just combined.

  • 11

    Place in a piping bag fitted with a medium-sized straight nozzle.

  • 12

    To assemble the cake, place a cake layer on a serving plate or cake stand, pipe dollops of frosting on top.

  • 13

    Repeat the layers with the cake and frosting, finishing with a layer of frosting on top.

  • 14

    Decorate the final layer with edible flowers.
