01 - Line an 8-inch square baking pan with parchment paper, allowing overhang on two opposite sides for easy removal later.
02 - Combine white chocolate chips, sweetened condensed milk, and butter in a medium saucepan over low heat. Stir continuously until completely melted and smooth, approximately 5-6 minutes.
03 - Remove from heat source and stir in vanilla extract. Let mixture cool for 2 minutes to prevent candy from melting when added.
04 - Fold half of the chopped candy eggs into the fudge mixture until evenly distributed.
05 - Pour fudge mixture into the prepared pan. Use a spatula to spread evenly and create a smooth surface.
06 - Sprinkle remaining candy eggs and pastel sprinkles over the top. Press gently into the surface to adhere.
07 - Refrigerate for minimum 2 hours or until completely firm and set throughout.
08 - Lift fudge from pan using parchment paper overhang. Cut into 24 equal squares and serve.
