Lightly grease the cups of a muffin pan with oil or oil spray.
Add the butter to a large pan and melt over a medium/low heat.
Add the marshmallow and stir until it’s all melted.
Remove the pan from the heat, pour in the rice krispies and stir until the cereal is completely coated.
Spoon the mixture into the muffin pan and form into a nest shape by making an indentation in the middle. A lightly buttered or oiled spoon makes it much easier!
Allow to cool completely in the pan before removing.
To decorate, make a fairly thick icing by mixing the powdered sugar with 2 teaspoons of water (add more water or icing sugar as necessary to make a thick paste) and add a few drops of green food colouring if desired.
Spoon a little icing into the rice krispie nests and place in a few mini eggs. Add a few sprinkles.
Notes
Make sure the muffin tin is greased fully.The well in the nest must be formed when the rice crispy treats are still warm. You can do this with your fingers or by using a lightly oiled or buttered spoon.The treats must cool completely before removing from the muffin tin. You can cool them faster by placing them in the fridge.Make sure the marshmallow is fully mixed in with the butter before adding the rice krispies to create an even texture throughout the treats.Serving Suggestions Place the rice krispie bird nests on the table in the middle of this Braided Italian Easter Egg Bread.Serve as dessert after a slice of Carrot Pizza.Bring to brunch along with a pitcher of Carrot Moscow Mule (for the grown ups).Filling suggestionsAdd your favorite candies to the middle of these Easter rice crispy treat nests such as:
