Beat together the dairy free spread and the icing sugar until smooth.
It needs to be smooth and soft enough to pipe. (Add a little milk if its not quite soft enough.)
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 half of the cherry compote.
Place the next sponge layer on top and press down gently.
Pip another ring of buttercream on top of the second sponge layer and fill with the cherry compote.
Top with the final layer of sponge cake and press down gently.
Use any buttercream left in the piping bag to fill any gaps between the layers.
Using a spatula, start covering the sides of the cake with buttercream trapping in as many crumbs as possible.
Split the remaining buttercream into two bowls. One bowl should contain 2/3rds of the buttercream and the other just 1/3.
Colour the larger portion of buttercream pale green and use to cover the cake.
Start by spooning it on to the top of the cake working in circular motions to smooth the icing out to the edges until it hands over slightly.
Add the remaining green icing to the sides of the cake (you may find it easier to use a piping bag to ensure even coverage before smoothing with a spatula).
Once the edges are smooth, add a star tipped nozzle to a piping bag and fill with the smaller portion of buttercream. Use this to pipe around the top of the cake to create a decorative edge. (You can also add detailing around the base of the cake or polka dots around the middle.)
Return any leftover icing to two bowls, colour one half a dark shade of green and the other bright red.
Divide this icing into separate piping bags fitted with round tip nozzles (alternatively just cut a very small opening in the end of the piping bag).
Carefully pipe two rows of small cherries using the red and green icing leaving roughly 1.5 inches between each. Any leftover icing can be used to pipe a messages on the top of the cake.
