I have got you covered with an awesome, fun and cool yet SCARY, SPOOKY and Creepy cake tutorial this Halloween - Spiderweb Cake that you can EASILY and EFFORTLESSLY recreate at home.
Prepare the chocolate cake (use store-bought or premix or your own favourite) and let it cool completely
Heat the cream until it just starts to boil and immediately pour over the chopped chocolate. Allow it to stand for a minute and then stir to combine. Let it sit in the refrigerator for 10 mins to thicken a bit and your ganache is all ready.
Melt your chocolate and keep it ready in a piping bag (refer notes)
Trim the chocolate cake if needed to level the top.
Pour the thickened chocolate ganache on top, spread it evenly on top of the cake.
Before the ganache sets immediately make roundels using melted chocolate on top of it starting from one corner of the cake. (refer video for clear steps)
With the help of a toothpick to make the cobwebs on top. Again refer video for a clear idea.
Once the ganache sets completely, arrange some spiders on top, place some fingers or bats to decorate. Slice a piece and enjoy.
