  • Total Time: 40 minutes
  • Yield: 64 one-inch squares

Ingredients

Essential Ingredients:

  • 3 cups (18 ounces) white chocolate chips
  • 1 can (14 ounces) sweetened condensed milk
  • ½ teaspoon peppermint extract
  • Green gel food coloring (or 2 tablespoons matcha powder)
  • Pinch of salt

Optional Additions:

  • 1 teaspoon vanilla extract
  • 2 tablespoons Bailey’s Irish Cream (adult version)
  • ½ cup chopped pistachios or walnuts
  • ½ cup mini chocolate chips
  • ¼ cup crushed Andes mints
  • Green sprinkles for topping

Instructions

  • Prepare pan: Line an 8×8-inch baking pan with parchment paper, leaving 2-inch overhangs on two sides for easy removal.
  • Melt chocolate: In a medium saucepan over low heat, combine white chocolate chips, sweetened condensed milk, and salt. Stir constantly for 3-5 minutes until chocolate is completely melted and mixture is smooth and glossy.
  • Add color and flavor: Remove from heat immediately. Stir in green food coloring (3-4 drops gel or 8-10 drops liquid, adjusting to desired shade) and peppermint extract. Mix thoroughly until evenly colored.
  • Pour and spread: Pour mixture into prepared pan, spreading into an even layer with a rubber spatula. Smooth the top surface.
  • Add toppings: If using sprinkles, nuts, or other toppings, add them immediately while fudge is still warm. Press gently to adhere.
  • Chill: Refrigerate for 2-4 hours until completely firm and set.
  • Cut and serve: Lift fudge from pan using parchment handles. Place on cutting board. Using a hot knife (run under hot water, then wipe dry), cut into 1-inch squares. Clean and reheat knife between cuts for cleanest edges.
  • Store: Keep in airtight containers with parchment between layers at room temperature (5 days), refrigerated (2 weeks), or frozen (3 months).

Notes

  • White chocolate quality: Use real white chocolate containing cocoa butter for best flavor and texture, not white candy melts.
  • Low heat essential: Never rush the melting process with high heat—low and slow prevents scorching and graininess.
  • Color intensity: Start with less food coloring; you can always add more. Color lightens slightly as fudge sets.
  • Natural coloring: Matcha powder creates beautiful natural green while adding subtle flavor and antioxidants.
  • Mint adjustment: Peppermint strength is personal preference. Start with ½ teaspoon and adjust to taste.
  • Thicker fudge: Use 8×8-inch pan. For thinner pieces, use 9×9-inch pan.
  • Make-ahead: Fudge improves after 1-2 days as flavors develop. Make up to 2 weeks ahead.
  • Hot knife trick: Running knife under hot water between cuts creates professional, clean edges.
