Clean all of the easter eggs and coat the inside with cooking spray. Set them aside.

In a saucepan, melt margarine or butter over a very low flame. Add the marshmallows
and stir them until they are completely melted. Remove from heat.

If your saucepan is large enough for it, add the Rice Krispies in and stir until well
coated. If your saucepan isn’t big enough, add the Rice Krispies to a bowl and pour
the marshmallow mixture on top. Stir until covered.

Using hands that are greased, press roughly ¼ of the mixture into each plastic half of
the egg. Use your fingers to create a hollow center in each half.

Once the eggs have set, remove them from the molds and place them on the wax
paper.

Place roughly six M&Ms in each egg half. Gently press the two halves together until
they stick. You will have to use patience and keep pressing the molding around the
seam.
