Line a square pan (8 x 8) with parchment paper, enough to have an overhang of parchment on all sides. Set aside.
In a large saucepan, mix together chocolate chips, condensed milk and butter. Melt over medium heat, stirring constantly.
Once all ingredients are well incorporated, remove from heat and quickly add vanilla extract. Mix quickly.
Pour fudge mixture into lined pan and spread evenly.
Top with candy eggs and allow to set in the refrigerator for at least 2 hours.
Cut with a sharp knife into small fudge squares (about 1-2 inches in size). Enjoy!
