Grease a cupcake pan with cooking spray or butter to prevent sticking. Set aside.

In a large microwave-safe bowl, combine marshmallows and butter. Microwave for about 2 minutes, watching carefully to make sure the marshmallows don't overflow as they puff up.
03 -
Stir the melted marshmallows and butter until well blended and smooth. Add the Rice Krispies cereal and mix until everything is evenly coated.

Spoon the Rice Krispie mixture into the greased cupcake pan. Press down in the center with a piece of wax paper to create a nest shape with slightly higher edges.
05 -
Allow the Rice Krispie nests to set for at least 30 minutes at room temperature before removing from the pan.
06 -
In a large bowl, combine softened butter, milk, vanilla extract, and 2 cups of powdered sugar. Beat for about 5 minutes until smooth and creamy. Add the remaining powdered sugar gradually until you reach your desired consistency.

Add green food coloring to the buttercream and mix well until you achieve the desired shade of green to resemble grass.

Once the Rice Krispie treats have set, pipe the green frosting onto each nest using a grass piping tip if available (or any tip with multiple small openings). Place a few Easter egg candies on top of each frosted nest.
