If you're a fan of Cadbury Creme Eggs then this dip is a must-make for spring! Use your favorite holiday chocolate (or even cookies or pretzels) for dipping.
Using a stand mixer (or a hand mixer + large bowl), beat the corn syrup, unsalted butter, and vanilla extract on medium high speed until smooth. Mixture will be very sticky; this is okay.
Drop mixer speed to low and slowly scoop in powdered sugar, about 1/2 cup at a time, until sugar is incorporated and mixture is thick.
Turn off mixture and add Cool Whip to bowl, then resume mixing at low speed until smooth, about 3-4 minutes. Stop mixer and use a spatula to thoroughly scrape around the sides, then beat again for another 3-4 minutes. If needed, repeat with scraping and mixing until the sticky sugar mix is completely combined with the cool whip.
Remove about 1/4 of the dip and place in a small serving bowl. Mix in orange food coloring, 1 drop at a time, until desired color is reached. For mine, I used 4 drops of gel food coloring. When finished, set bowl nearby.
Scoop the remaining dip into a serving bowl of your choice. Make a small well in the top where the orange dip will go.
Spoon orange dip into the well you created in the white dip.
Serve dip immediately with milk or dark chocolate candy bars for dipping.
