Prepare an 8x8-inch pan by lining with parchment paper then spraying with a nonstick cooking spray.
Place a medium saucepan on the stove over low heat. Pour in condensed milk and heat until hot but not boiling.
Add sugar cookie mix and stir well. Once mixed, add chocolate chips, butter, and extract.
Stir constantly until the mixture is melted and smooth.
Remove from heat and stir in 3-4 tablespoons of holiday sprinkles.
Pour into the prepared pan, smooth the top, and sprinkle the remaining sprinkles over the top. Pat gently to help the sprinkles stick to the fudge.
Chill in the refrigerator for 2-4 hours. Let it come to room temperature before cutting. Serve at room temperature for the most flavor.
