Prepare the Baking Dish

Line a 9x9-inch baking dish with parchment paper and lightly coat it with non-stick spray. This step ensures easy removal once the fudge has been set.

Heat the Base Mixture

In a large pot over medium heat, warm the sweetened condensed milk.

Once heated, add the white chocolate chips, sugar cookie mix, and butter.

Melt and Mix

Stir continuously until the white chocolate chips are fully melted and the mixture becomes smooth and creamy.

Add Sprinkles

Stir in a handful of sprinkles to add a festive touch to the fudge.

Pour and Decorate

Pour the mixture into the prepared baking dish.

Use a spatula to smooth the surface, then top generously with more Christmas sprinkles.

Set the Fudge

Refrigerate the dish for at least 2 hours or until the fudge is firm. For best results, let it chill overnight.

Slice and Serve

Once set, lift the fudge out of the dish using the parchment paper. Slice into squares and serve.
