Prepare the Fudge

1. Melt the Mixture: In a medium saucepan over low heat, melt together the sweetened condensed milk, white chocolate chips, and butter. Stir occasionally until everything is smooth and well combined.
2. Add Flavor: Stir in the vanilla extract and sugar cookie crumbs. Continue stirring until fully incorporated.
3. Set in the Pan: Line an 8×8-inch baking pan with parchment paper. Pour the fudge mixture into the pan and spread it out evenly with a spatula.
4. Chill: Refrigerate the fudge for at least 45 minutes or until it’s firm to the touch.
5. Cut and Serve: Once set, remove the fudge from the pan using the parchment paper and cut it into squares. Top with sprinkles or colored sugar for a festive touch, if desired.
