Line an 8x8 inch square baking pan with parchment paper, ensuring an overhang for easy removal.
In a heavy-bottomed saucepan or microwave-safe bowl, combine the white chocolate chips and sweetened condensed milk.
Heat on low, stirring constantly until the chips are completely melted and the mixture is homogenous. If using a microwave, heat in 30-second intervals at 50% power, stirring between each.
Remove from heat and stir in the vanilla extract and salt.
Gently fold in 1/2 cup of the mini chocolate eggs.
Transfer the mixture to the prepared pan and spread into an even layer using a silicone spatula.
Press the remaining 1/2 cup of mini chocolate eggs and the sprinkles into the surface of the fudge.
Refrigerate for at least 2 hours, or until the fudge has set completely.
Lift from the pan using the parchment overhang and slice into 1-inch squares with a sharp knife.
