Step 1

Line a 9-inch square baking pan (or you could use 8-inch) with parchment paper and spray with non-stick cooking spray.

Step 2

To a medium-sized saucepan set over medium heat, add chocolate chips, sugar cookie mix, butter, and sweetened condensed milk. Using a wooden spoon or heat-proof silicone spatula, stir well to combine.

Step 3

Cook for about 5 minutes, until the chocolate is melted and the mixture is smooth. Then, remove the pan from the heat. Add the vanilla and ½ cup holiday sprinkles to the pan, and stir to combine.

Step 4

Pour mixture into the prepared pan and sprinkle remaining holiday sprinkles over the top.

Step 5

Refrigerate for about an hour, or until the fudge is firm. Using a sharp knife or bench scraper, cut the fudge into 16 squares.
