This post is dedicated to Bianca from Bucataria din casa mea, who is learning the cake decorating secrets and I promised her this tutorial.
you need to shape your cake as square as possible, if you don't have a perfect shape mold you should use a knife and cut it, so that you have straight edges.
Cover you cake in butter cream, as smoothly as you can.
Roll out your fondant/ sugar paste/ MM fondant and cut it into equal stripes.
Place them on the cake one by one and cut off the excess.
Continue to do so until you have the whole cake covered.
Then roll out a big piece of fondant and cover your cake with it.
Then with a knife and a ruler cut off the margins on all four sides and you have the lid.
There is your box cake. You can decorate it as you please.
This time I decorated mine with fresh flowers, but I'll make a bow tutorial soon, so that you can see how to do it.
I hope it helped!
