Instructions

• Line an 8×8-inch baking pan with foil, leaving an overhang for easy removal, and spray the foil lightly with cooking spray.
• In a medium saucepan, combine 3 cups semi-sweet or milk chocolate chips and the 1 14‑ounce can of sweetened condensed milk.
• Warm the mixture over medium-low heat, stirring constantly with a heatproof spatula or wooden spoon until the chocolate is completely melted and the mixture is smooth and glossy (do not let it boil).
• Remove the pan from the heat and stir in 1 teaspoon vanilla extract until evenly incorporated.
• Pour the chocolate mixture into the prepared pan and spread it into an even layer with an offset spatula or the back of a spoon.
• Working quickly while the surface is still soft, press 10–12 Fun Size Kit Kat bars (broken into sticks) into the top of the fudge in a single layer so they adhere.
• Let the fudge cool to room temperature on the counter, then refrigerate until fully set, at least 1 hour. Use the foil overhang to lift the fudge from the pan, peel off the foil, and cut into pieces.
