Beat together the dairy free spread and the icing sugar until smooth.
Melt the white chocolate then beat into the buttercream mix.
Add the milk a little at a time while continuing to beat - do this until you have a smooth, pipe-able buttercream. (You may need more or less milk depending on your buttercream).
Spread a little buttercream on a cake board or cake plate and place down the first layer of sponge cake.
Fill an icing bag with a quarter of the icing and carefully pipe a ring of buttercream around the top of the sponge cake layer.
Fill the middle of the buttercream ring with the raspberry jam.
Place the sponge layer on top and press down gently.
Pipe buttercream around the outside and top of the cake until covered.
Using a spatula, start covering the sides of the cake with buttercream trapping in as many crumbs as possible.
Using a large, offset spatula run it around the outside of the cake and on top of the cake until it is smooth.
Divide the remaining buttercream into two bowls and colour one light pink and the other dark pink.
Using a smaller spatula, add blobs of the two shades of pink around the cake at random.
Take the large spatula and again run it around the outside of the cake until smooth
Place an open star nozzle into a second piping bag and fill with the remaining buttercream.
Pipe swirls on the top of the cake then finish with fresh raspberries.
