Cream-cheese icing
100g mascarpone
200g cream cheese
100g icing sugar
10ml lemon juice
Handful fresh blueberries and a few stems of lavender

Preheat your oven to 180˚C/350˚F/gas mark 4 and set aside three greased 8in sandwich tins. Blitz the lavender flowers and sugar in a processor until well mixed. In the bowl of a stand mixer, cream the butter and lavender sugar until fluffy and beat the eggs before adding them gradually.

Remove the bowl from the stand mixer and fold the self-raising flour and ground almonds through the mix with as few folds as possible. Stir in the soured cream and then pour into a prepared tin. Bake for about 20 minutes, or until a skewer comes out clean, and turn out onto a wire rack to cool completely.

Clean the bowl from your stand mixer before adding the unsalted butter and caster sugar, creaming them together until fluffy. Add the beaten eggs, a little at a time, and mix until incorporated. Fold the ground almonds, lemon zest and juice through, followed by the self-raising flour and the soured cream. Divide the mixture between two sandwich tins and bake for about 20 minutes, or until a skewer comes out clean.

In the meantime, heat the sugar and lemon juice together in a small saucepan. While the cakes are still hot, make holes with a toothpick over the top and drizzle the lemon syrup over them. Turn the cake out onto a wire rack and leave to cool completely.

Make the icing by mixing the mascarpone, cream cheese, icing sugar and lemon juice in the bowl of your stand mixer until smooth.

To assemble the cake, place a lemon layer on a plate and smooth a few tablespoons of icing over it. Add the lavender layer, more icing and then the top lemon layer and further icing. Ice all around the cake and decorate with fresh blueberries and stems of lavender. Serve with a dollop of mascarpone on the side.
