**Prepare the Pan:** Line an 8x8-inch baking pan with parchment paper, leaving some overhang for easy removal.
**Melt the Chocolate:** In a medium saucepan, combine the white chocolate chips and sweetened condensed milk. Cook over low heat, stirring constantly, until the chocolate is completely melted and smooth.
**Add Flavoring:** Remove the saucepan from heat. Stir in the strawberry syrup or puree, vanilla extract, and food coloring (if using). Mix until fully combined.
**Pour into Pan:** Pour the fudge mixture into the prepared pan, spreading it evenly with a spatula.
**Garnish:** Sprinkle crushed freeze-dried strawberries over the top for added texture and flavor (optional).
**Chill:** Refrigerate the fudge for at least 2–3 hours, or until firm.
**Cut and Serve:** Once set, lift the fudge out of the pan using the parchment paper. Cut into small squares and enjoy.
