Line a baking sheet with parchment paper. Preheat oven to 350.
In a medium sized bowl, whisk together coconut, flour, and sugar (if adding).
Add condensed milk and extracts. Stir to combine.
Using a large scoop, drop cookies onto the baking sheet. Use your fingers to press them into a nest shape.
Bake in preheated oven for 15 minutes, or until the coconut on the top and edges is toasted.
Let cool.
Fill your nests with Cadbury eggs.
