In a large saucepan, add the Mars® Bars Fun Size (12) and Butter (75 gram). On a low to medium heat, stirring occasionally, cook until the mixture is melted together and smooth.
Add in the Puffed Rice Cereal (3 cup). Stir together.
Transfer the mixture into a 12-hole muffin pan lined with paper cases. Push down the mixture in each cup with the back of a teaspoon to make a nest shape. Set aside to cool for 15 minutes.
In a microwave-safe bowl, add Milk Chocolate (200 gram). Cook for 2 minutes in the Panasonic Microwave Oven, stopping every 30 seconds to stir.
Add butter to the melted chocolate and stir to combine.
Spoon the chocolate mixture into each nest. Decorate with Easter Egg Candy (1 package). Chill in the fridge until completely set.
Serve and enjoy! Cooking results may vary depending on microwave oven used.
