Method

  • step 1

    Heat the oven to 180C/160C fan/gas 4. Butter and line the base and sides of two 20cm sandwich tins.

  • step 2

    Beat the butter and sugar together in a large bowl with an electric whisk for 8-10 mins, or until pale and fluffy. Add the eggs one at a time, beating well after each addition. Sift in the flour, baking powder and salt, and fold in using a large metal spoon. Add just enough of the milk to create a dropping consistency.

  • step 3

    Divide the batter between the prepared tins and smooth the tops with a spatula. Bake on the middle shelf of the oven for 25-30 mins, or until golden and firm to the touch. Leave to cool slightly in the tins, then transfer to a wire rack to cool completely.

  • step 4

    Meanwhile, make the macerated berries. Mix the sugar, lemon juice, vanilla and mint together until the sugar has dissolved. Gently stir in the strawberries and raspberries until coated in the mixture. Transfer to the fridge and chill for 30-45 mins until softened.

  • step 5

    To make the crème diplomat, put the custard, vanilla pod and sugar in a pan set over a medium heat and bring to the boil, stirring occasionally. Mix the custard powder with 3 tbsp water to dilute and stir until smooth. Whisk into the boiling custard, then reduce the heat to a simmer and continue whisking for 2-3 mins until thick. Put in a heatproof bowl and leave to cool slightly, then chill until cooled completely. Whisk the double cream to soft peaks, and when the custard is cool, remove the vanilla pod and whisk in the cream until the mix is thick enough to pipe.

  • step 6

    Drain the macerated berries, reserving the liquid. To assemble, spread half the crème diplomat over one of the sponges, then top with three-quarters of the berries. Invert the second sponge on top, so the flat base of the sponge is facing up, and dust with some icing sugar. Put the remaining crème diplomat in a piping bag fitted with a star nozzle and pipe rosettes around the edge of the cake. Dot the rest of the berries between the rosettes of cream, and serve with the reserved macerating liquid alongside – don’t pour it over before serving as it will split the crème diplomat. Will keep in the fridge for up to three days.

I mixed the custard powder/water into the cold custard before boiling it, this way it didn’t go lumpy at all…. providing you stir it constantly.

Hi. Hope not a silly question, but if I double up on sponge quantities, will the baking time also double? Thanks.

Hi, thanks for your question. Not silly at all, but it does depend on the tin sizes you're planning to use. Are you planning to use 4 x 20cm tins, or 2 larger tins? If you let us know then hopefully we can help (please post it as a new question rather than a reply to this one, just to make sure we…

How long in advance could you make this cake? Would it last 36 hours?

question

Looking for suggestion to replace the custard. I'm in Canada and we dont have store bought custard. Suggestions? Would I make some Birds Custard and let it set? thanks!

Hi, thanks for your question. We've only tested this with the fresh custard which is usually quite rich with cream. However it should be fine to make up some other custard instead and use that. As you will be bringing it all to the boil in the beginning of step 5, you probably don't need to let it…
