This looks way harder than it is. The hardest thing was keeping my hand steady while piping the chocolate out. I used a flower cake pan and made a chocolate cake from scratch ( google it). I used a big flower nozzle and put white butter icing all over the cake. I melted Hersheys chocolate chips for the chocolate.

Step 1: Pipe Melted Chocolate on Wax Papper Over a Template

I cut and traced these shapes from my cake pan.

Step 2: Set Chocolate

Allow chocolate to mostly set but not fully and place face down on desired place on cake. Place cake in fridge to harden with paper still on. Peel off paper slowly when chocolate is hard.
