Instructions

Prepare the Baking Dish: Line an 8×8-inch square baking dish with parchment paper, ensuring there is an overhang on the sides to easily lift the fudge out later.
Melt the Base Ingredients: In a saucepan over medium-low heat, combine the white chocolate chips, sweetened condensed milk, and unsalted butter. Stir constantly to prevent burning until the mixture is fully melted and smooth.
Add Flavorings: Remove the saucepan from heat. Stir in the key lime zest, key lime juice, vanilla extract, a pinch of salt, and if desired, 1-2 drops of green food coloring to achieve a light green tint.
Pour and Smooth: Quickly pour the mixture into the prepared baking dish, then smooth the top evenly using a spatula.
Chill to Set: Place the dish in the refrigerator and chill for at least 3 hours, or until the fudge is fully set and firm.
Cut and Serve: Lift the fudge out of the dish using the parchment paper overhang, cut into approximately 36 squares, and serve.

Notes

For freshest flavor, use freshly zested and juiced key limes, but bottled juice works well in a pinch.
Ensure constant stirring when melting to avoid scorching the white chocolate.
Store fudge in an airtight container in the refrigerator for up to one week.
Allow fudge to come to room temperature for a few minutes before serving for softer texture.
Add a drop or two of green food coloring for a festive presentation without altering flavor.
