Beat the butter for 4-5 minutes until it’s smooth and fluffy. Slowly add the icing sugar to the butter and continue to beat for a further 2 minutes, add the vanilla and beat until smooth Now it’s time to add the brown food colouring to create the colour of your terracotta plant pot. Add one drop of the food colouring at a time until you reach your desired colour. Once the cakes have cooled it is time to spread the buttercream frosting evenly in-between each layer of cake, and then smooth the buttercream around the sides of the cake. You now want to shape the cake using a sharp knife, you want the smallest layer to be at the bottom and the largest at the top – trimming the edges of the cake until you have created the shape of a flower pot.
