In a bowl of cold water, add 2-3 drops of black food coloring. Mix until incorporated.
Take the back of a spoon and gently tap all around each egg, creating little cracks.
Place each egg in the black water then place in the fridge for 2 hours.
After your eggs have chilled in the black water, remove the bowl from the fridge,
De-shell each egg then cut each egg in half lengthwise.
Remove the yolks from each egg half and place in a medium-sized bowl.
In the same bowl, add the mayonnaise, cajun seasoning, paprika, garlic powder, and dijon mustard. Mix until combined.
Add 2-3 drops of orange food coloring and mix until incorporated.
Transfer the egg mixture to a piping bag with a star tip.
Pipe a dollop into the center of each hard boiled egg half.
Add a green jimmy sprinkle to the top of the dollop and now you have a cute pumpkin!
Serve and enjoy!
