Coolest Princess Castle Birthday Cake

I made this Princess Castle Birthday Cake for my daughter’s 6th birthday. I made the whole thing from scratch, not using any packet mixes or ready made icing. I started with the main round part of the cake and covered it with icing then made Swiss rolls from scratch and covered them with icing then stuck the whole thing together and left to settle.

Once it was sturdy enough I cut out the windows from black coloured icing and piped in the white lines. I made the flowers by hand and left them to dry. Once dry I stuck them to the cake and piped in the vines and leaves.
