Cut the bars into rectangular shapes and place individual pieces on a large plate or platter and set in the fridge or freezer for a couple of minutes.
While the bar treats are cooling, melt chocolate and oil in a microwave-safe bowl. Microwave for 1 minute. Stir and return to microwave for 15-20 second intervals, stirring in between until chocolate is completely melted and smooth.
Spoon the melted chocolate into a ziplock bag and snip a tiny section off of one corner of the bag.
Using a little dab of icing where you want the eyes and place candy eyes on those spots.
Drizzle icing over each bar in a random pattern to create the look of mummy wraps.
Return mummy treats to the fridge/freezer for a couple of minutes.
If not serving immediately, you can store these in an airtight container for up to 1 week.
