A dark chocolate cake filled with raspberry buttercream frosting. Covered in black chocolate buttercream. The Deadpool emblem is made with raspberry flavored fondant. It’s decked out with all kinds of weapons made from fondant including swords giving the illusion of going through the cake.

And of course the star of the cake is the Deadpool action figure. Could easily change it to be a cool Ninja cake.
