Preheat your oven to 350F and prepare a baking tray with parchment lined paper.
In a large bowl, add in your sugar cookie mix, egg, butter and combine together until a ball of dough forms.
Portion out each cookie dough into similar size balls using a cookie scooper or just with your hands, place each cookie on parchment paper about 1 1/2 - 2 inches apart.
Use a spoon or cookie scooper to create a dent in the middle then place in the oven to bake for 10-12 minutes or until the cookies have golden edges/bottom.
Once cookies are done, use spoon/cookie scooper again to press a dent in the middle and let cool. Add your mini eggs on top either just by itself or place with melted chocolate first to hold.
Serve with a glass of milk and enjoy!
