Melt marshmallows and butter on low heat, stirring continuously to prevent scorching.
Measure cereal out into a large bowl and pour melted marshmallows over the top.
With a large spoon stir cereal until well mixed and evenly coated with marshmallow.
Make a disk shape with sticky cereal approximately 5" across and use your thumbs to push up the sides to create a nest shape.
You'll want to work quickly so the cereal is still pliable by the last next.
Once all 10 nests are created, melt chocolate chips in microwave in 30 second bursts, stirring between.
When melted add 1/2 tsp melted coconut oil and stir well.
Using your spoon, drizzle chocolate across the tops of all the nests and let cool to harden.
Store in an airtight container but they are best if eaten the same day.
For serving, add 3 Cadbury mini eggs to the center of each nest.
Enjoy!
