Prepare an 8x8 inch baking dish by lining it with parchment paper, leaving some overhang for easy removal.
In a medium saucepan, heat the dark chocolate chips and sweetened condensed milk over low heat, stirring constantly until the chocolate is fully melted and combined.
Remove the saucepan from the heat and stir in the vanilla extract.
Gently fold in the crushed freeze-dried strawberries until evenly distributed in the chocolate mixture.
Pour half of the chocolate-strawberry mixture into the prepared baking dish and spread it evenly.
Arrange the halved fresh strawberries on top of the first layer of fudge.
Pour the remaining chocolate-strawberry mixture over the fresh strawberries, smoothing it out to cover completely.
Sprinkle a pinch of sea salt on top for a flavor contrast.
Refrigerate for at least 2 hours or until firmly set.
Once set, lift the fudge from the baking dish using the parchment paper overhang and cut into squares.
Notes
Serve the fudge squares on a decorative plate, garnished with additional fresh strawberries for a pop of color.
