01 - Line an 8-inch square baking pan with parchment paper, leaving an overhang on two sides for easy removal.
02 - In a medium saucepan over low heat, combine the white chocolate chips, sweetened condensed milk, and butter. Stir constantly until melted and smooth, about 5–6 minutes.
03 - Remove from heat and stir in vanilla extract. Allow to cool for 2 minutes, then fold in half of the chopped candy eggs.
04 - Pour the mixture into the prepared pan and smooth the top with a spatula.
05 - Sprinkle the remaining candy eggs and pastel sprinkles evenly over the surface, gently pressing them in.
06 - Refrigerate for at least 2 hours, or until firm.
07 - Once set, lift the fudge from the pan using the parchment overhang and cut into 24 squares.
