1largePie Plate or Casserole PanAny large flat container works, but you want it to have an edge that is at least a few inches tall.
Soak hardboiled eggs that are compleletly cool in a layer of vinegar for 5-10 minutes. This will help your colors to be more vibrant and stick to the egg. If you skip this step, the colors will be much less vibrant. Dry eggs off and set to the side.
In a large flat dish or container, spread about a generous layer of Cool whip on the bottom that is about an inch thick.
Carefully place dots of food coloring all around. You can make it multiple colors or have certain colors in one area. Anything goes!
Take a spoon or butter knife and swirl the cream until it looks like tie dye. You want to swirl just enough that the colors start to swirl a little in the cream, but not so much that the cool whip starts to become all the same color.
Place the hardboiled eggs in the whipped cream gently with a spoon. Rotate each egg in its spot until it’s totally covered with whipped cream.
Place the entire pan in rthe efrigerator for about 10-15 minutes.
Take out and wipe the cream off of the eggs off with paper towels. Try to avoid rinsing with water as it causes a lot of the color to come off and the colors won’t be as bold looking.
Let your eggs dry and enjoy! These eggs are perfectly safe to peel and eat once dry.
If you touch the eggs with your fingers, the food coloring can stain for about a day. I recommend using disposable gloves or placing your hands in zip-top disposable bags when moving the eggs if you are worried about the coloring staining. Using a spoon can be helpful, but will still likely end up messy without gloves if you are making these eggs with young children.
Each egg will have different colored swirls using this method, but if you want more control over the colors on each specific egg try using a muffin tin to hold the cool whip and dye for each individual egg.
With younger children, cool whip and food coloring can be placed in plastic zip-top bags to help the project to be less messy.
Other types of vinegar besides white vinegar will often change the color of the eggs. Apple cider, balsamic, rice wine vinegar and other varieties all tend to leave a stain of brown color behind on the eggs. I recommend using white distilled vinegar for this project.
