First, you need to prepare the Cadbury Creme eggs. Unwrap them and, using a knife, split them in half – try to keep them intact! If you find that they are a little runny, place them in the freezer until the inside hardens up a tad.
Take a small saucepan, add an inch of water and put it over high heat. Add a bowl, making sure the bottom doesn’t touch the water and use it to melt the chocolate.
While you wait for the chocolate to melt, line the baking tray with butter and baking parchment. This will make it a lot easier to get the fudge out of the tray.
In a separate, larger bowl, mix the condensed milk and powdered sugar together. Then slowly add the chocolate. Make sure all of the condensed milk is mixed in, otherwise, it won’t set and it will be far too gooey!
Before the mixture begins to set, pour it into the lined tray. Use a spoon or spatula to make sure the mixture is even across the tray.
Grab the Cadbury Creme eggs and place them open side down into the Ooey Gooey Fudge and press them down slightly.
Mix together some powdered sugar, food gel coloring, and water so the consistency is thin, but not watery. You want it to slowly run off the spoon.
Take a spoonful of icing and flick it over the fudge. You can add as much or as little as you'd like.
Let set overnight for best results.
