Description

Homemade Mars bar candy bars with soft nougat, rich caramel, and a smooth milk chocolate coating. Perfectly layered, indulgent treats made from scratch.


Ingredients

  • Nougat Layer:
  • ¼ cup (57 g) unsalted butter
  • 1 cup (200 g) granulated sugar
  • ¼ cup (60 ml) evaporated milk
  • 1 ½ cups (150 g) marshmallow fluff
  • ¼ cup (60 ml) water
  • 1 teaspoon pure vanilla extract
  • 1 ½ cups (180 g) powdered sugar
  • Caramel Layer:
  • 1 cup (200 g) granulated sugar
  • ¼ cup (60 ml) heavy cream
  • 2 tablespoons (28 g) unsalted butter
  • ¼ teaspoon salt
  • Chocolate Coating:
  • 2 cups (340 g) milk chocolate chips
  • 1 tablespoon (15 ml) vegetable oil

Instructions

  1. Line an 8×8-inch pan with parchment paper and lightly grease it.
  2. For nougat: In a saucepan over medium heat, combine butter, sugar, evaporated milk, and water. Stir until sugar dissolves and butter melts; bring to gentle boil for 4–5 minutes.
  3. Remove from heat, stir in marshmallow fluff and vanilla until smooth. Gradually mix in powdered sugar until thick. Spread evenly in prepared pan and let cool 30 minutes.
  4. For caramel: Melt sugar over medium heat until deep amber. Carefully add cream while stirring, then stir in butter and salt. Cook 1–2 more minutes until slightly thickened. Cool 5 minutes and pour over nougat layer. Refrigerate 30–45 minutes until firm.
  5. For chocolate coating: Melt chocolate chips with oil in microwave in 30-second intervals, stirring until smooth. Pour over chilled caramel and spread evenly. Refrigerate at least 1 hour until set.
  6. Lift candy from pan using parchment, slice into bars with sharp knife, wiping knife between cuts.

Notes

  • Use dark chocolate instead of milk chocolate for richer flavor.
  • Sprinkle flaky sea salt over caramel before chocolate for salted caramel twist.
  • Add ½ cup finely chopped roasted peanuts over nougat before caramel for extra texture.
  • Cut into mini bite-size squares for party platters.
  • Use a loaf pan for thicker bars.
  • Store airtight at room temperature up to 4 days, refrigerate up to 2 weeks, or freeze up to 2 months.
