Beat the butter, brown sugar, vanilla, and milk in a mixing bowl.
Add the flour and salt and mix until combined.
Fold in the chocolate chips.
For each egg, roll out ~1/2 tbsp of dough into an egg-like shape. Place on a baking sheet lined with parchment paper (makes ~56).
Once you've turned all the dough into mini eggs, place them into the freezer. Freeze until solid.
Once frozen, leave in the freezer while you melt the chocolate.
