Once the Chocolate Decadence Cake has defrosted, cut into quarters, place in a small microwave-safe bowl, and microwave for 35 seconds.
Add 2 cups of giant cashews and mix.
Place half of the mixture onto a sheet of plastic wrap.
Roll into 2-inch-diameter cylinder, repeat with the remaining mix, and refrigerate until the cylinders have become firm.
Remove the mixture from the plastic, slice into quarter-inch medallions, and place on tray or parchment paper.
Keep cool and covered until ready to serve.
