📝 About This Recipe

A cult classic born in the chip shops of Stonehaven, Scotland, this indulgent treat transforms a standard chocolate bar into a molten masterpiece. The crisp, golden-brown savory batter provides a dramatic textural contrast to the gooey caramel and softened nougat inside. It is the ultimate guilty pleasure, offering a salty-sweet symphony that has become a global symbol of adventurous comfort food.

🥗 Ingredients

The Confectionery

  • 4 full-sized bars Mars Bars (chilled in the freezer for at least 2 hours)

The Signature Batter

  • 1 cup All-purpose flour (plus extra for dredging)
  • 1/4 cup Cornstarch (helps achieve maximum crispness)
  • 1/2 teaspoon Baking soda
  • 1/4 teaspoon Fine sea salt
  • 1/2 cup Whole milk (very cold)
  • 1/2 cup Sparkling water or light lager (ice cold for a light, airy texture)

Frying and Finishing

  • 1 quart Vegetable oil (for deep frying; use a high smoke point oil like peanut or canola)
  • 1 tablespoon Powdered sugar (for dusting)
  • 4 scoops Vanilla bean ice cream (for serving)

👨‍🍳 Instructions

  1. 1

    Place the Mars Bars in the freezer for at least 2 hours before cooking. This is crucial to ensure the chocolate doesn't melt completely before the batter sets in the fryer.

  2. 2

    In a large heavy-bottomed pot or deep fryer, heat the vegetable oil to exactly 375°F (190°C). Use a candy or deep-fry thermometer to monitor the temperature closely.

  3. 3

    In a large mixing bowl, whisk together the all-purpose flour, cornstarch, baking soda, and salt until well combined.

  4. 4

    Slowly pour the cold milk and the ice-cold sparkling water (or beer) into the dry ingredients.

  5. 5

    Whisk the mixture gently until just combined. Do not overmix; a few small lumps are perfectly fine and help create a craggy, crunchy texture.

  6. 6

    Place about 1/2 cup of extra flour in a shallow dish for dredging.

  7. 7

    Remove the chilled Mars Bars from the freezer and unwrap them immediately.

  8. 8

    Roll each bar in the shallow dish of flour, shaking off any excess. This 'dry coat' ensures the wet batter adheres perfectly to the smooth chocolate surface.

  9. 9

    Dip a floured bar into the cold batter, ensuring it is completely submerged and coated from end to end.

  10. 10

    Carefully lower the battered bar into the hot oil. Fry only 1 or 2 bars at a time to prevent the oil temperature from dropping.

  11. 11

    Fry for 90 seconds to 2 minutes, turning once with a slotted spoon, until the batter is a deep golden brown and impressively crisp.

  12. 12

    Use a slotted spoon to remove the bar and place it briefly on a wire rack set over paper towels to drain any excess oil.

  13. 13

    Let the bar rest for about 1 minute—the residual heat will finish softening the center without it leaking out.

  14. 14

    Dust lightly with powdered sugar and serve immediately while the contrast between hot and cold is at its peak.

💡 Chef's Tips

Ensure the bars are frozen solid; a room-temperature bar will disintegrate into the oil and create a mess. Keep your batter liquids ice-cold; the temperature shock between the cold batter and hot oil creates a steam barrier for a lighter crust. Don't over-crowd the pot, as this leads to soggy batter and greasy results. If you don't have sparkling water, a light pilsner or lager adds a wonderful depth of flavor and extra carbonation for lift. Use a high-sided pot to avoid oil splatters, as the moisture in the batter will cause some bubbling.

🍽️ Serving Suggestions

Serve alongside a large scoop of premium vanilla bean ice cream to balance the richness. Drizzle with a salted caramel sauce or a sharp raspberry coulis for a gourmet touch. Pair with a strong cup of black tea or a cold glass of milk to cut through the sweetness. For a truly Scottish experience, serve with a side of shortbread crumbles. Enjoy immediately; this dish does not reheat well and is meant to be eaten fresh and hot.
