10-Minute Double Chocolate Walnut Fudge

These Double Chocolate Walnut Fudge bars require only five ingredients and about ten minutes of hands-on time. Rich, creamy and easy to make, this fudge is perfect for gifting, potlucks, or a simple family dessert. The contrast of dark and white chocolate gives it a “tuxedo” look, so it’s sometimes called Tuxedo Fudge.

How to make the easiest 10-minute Double Chocolate Walnut Fudge

This version uses semi-sweet and white chocolate chips combined with sweetened condensed milk to create two layers: a chocolate base and a white chocolate top. Walnuts add a pleasant crunch, and vanilla highlights the chocolate flavors. The method is simple: melt chocolate with condensed milk, mix, layer, chill, and cut into squares.

Ingredients

  • 1 ½ cups semi-sweet chocolate chips
  • 1 cup white chocolate chips
  • 1 can (14 ounces / 400 g) sweetened condensed milk, divided
  • 1 teaspoon vanilla extract, divided
  • 1 cup roughly chopped roasted walnuts (plus extra for topping)
  • ¼ cup extra chocolate chips for topping (optional)

Instructions

  1. Line a 7- or 8-inch square pan with parchment paper or wax paper. Double-line if you prefer easier removal.
  2. Divide the condensed milk into two microwave-safe bowls — roughly two equal portions (about 2/3 cup each) — to melt with the semi-sweet and white chocolate separately.
  3. For the dark layer: place the semi-sweet chocolate chips and half the condensed milk in a bowl. Microwave on high for 1 minute, stirring every 15 seconds, until smooth. If using a stovetop, melt gently in a double boiler. Stir in ½ teaspoon vanilla once melted.
  4. Fold the chopped walnuts into the melted semi-sweet mixture, reserving a handful for the top. Spread this mixture evenly in the prepared pan, pressing lightly to form a smooth base.
  5. For the white layer: melt the white chocolate chips with the remaining condensed milk in the second bowl, using the same microwave method (1 minute, stirring every 15 seconds) or a double boiler. Stir in the remaining ½ teaspoon vanilla.
  6. Carefully spoon or pour the white chocolate mixture over the dark layer and spread gently with a spatula to create an even top layer.
  7. Sprinkle the reserved walnuts and the extra chocolate chips over the top, if desired. Cover with plastic wrap or foil.
  8. Refrigerate for 3–4 hours or until firm. Once set, lift the parchment to remove the fudge from the pan and cut into squares with a sharp knife.
  9. Store the fudge in an airtight container at room temperature for up to one week, or in the refrigerator for 2–3 weeks.

Notes

  • The recipe is easy to double or triple if you want more or taller fudge bars — use a larger or deeper pan as needed.
  • Swap walnuts for other nuts you prefer, or omit nuts entirely for a smooth texture.
  • Other mix-ins that work well include rice cereal, marshmallows, dried fruit, crushed pretzels or candy pieces — get creative.
  • For softer, chewier fudge, use a ratio of about 2.5 cups chocolate to one 14-oz can of condensed milk. For firmer fudge, increase to about 3 cups chocolate per 14-oz can.
  • If you prefer a single chocolate variety, you can make the entire fudge using just semi-sweet or just white chocolate.
  • Compound or coating chocolates will also work if you need a simpler melting option.
