Creating your own Peppermint Swirl Fudge is both simple and enjoyable. Follow these steps for a delicious outcome:

1. Prepare the Pan: Line an 8-inch square baking dish with parchment paper, leaving some overhang for easy removal.
2. Melt Semisweet Chocolate: In a large saucepan, combine the semisweet chocolate chips and half of the sweetened condensed milk. Heat over medium-low, stirring until melted and smooth.
3. Add Flavors: Stir in 1/2 teaspoon of peppermint extract and 1/4 teaspoon of vanilla extract into the melted chocolate mixture.
4. Pour Mixture: Pour the semisweet chocolate mixture into the prepared baking dish, spreading it evenly.
5. Melt White Chocolate: In a clean saucepan, combine the white chocolate chips with the remaining sweetened condensed milk. Heat over medium-low until melted and smooth.
6. Color White Chocolate: If desired, add a few drops of red food coloring to the white chocolate mixture. Swirl gently to create a marbled effect.
7. Add Swirl: Pour the white chocolate mixture on top of the semisweet chocolate layer. Use a knife or toothpick to create swirls.
8. Sprinkle Toppings: If using, sprinkle crushed peppermint candies over the top.
9. Chill the Fudge: Refrigerate the fudge for at least 2 hours, or until set.
10. Cut and Serve: Remove the fudge from the baking dish by lifting the parchment paper. Cut into squares and enjoy!
