Mix in Marshmallows and Mini Eggs: Gently fold in the mini marshmallows and crushed mini chocolate eggs without overmixing.
Spread in Pan: Pour the mixture into the prepared pan and smooth the top with a spatula.
Decorate: Press additional mini eggs and sprinkles on top for a festive finish.
Chill: Refrigerate for at least 2 hours until fully set.
Serve: Lift the fudge out, cut into squares, and enjoy!
