- 1
First, place 1 Mars bar in the freezer for at least 30 minutes; this crucial step helps it maintain its shape and prevents it from melting too quickly when it hits the hot oil, ensuring a perfect gooey centre.
- 2
While your chocolate bar chills, prepare the batter. In a medium bowl, whisk together 100g of plain flour, 1 teaspoon of baking powder, and a tiny pinch of salt. Gradually add 120ml of cold milk and 1 large egg, whisking until you have a smooth, thick batter with no lumps, similar to a pancake consistency.

Next, heat your oil. Pour vegetable oil into a deep, heavy-bottomed saucepan or a deep fryer, to a depth of about 7-10 cm (3-4 inches). Heat the oil over medium-high heat until it reaches 170-180°C (340-350°F). A kitchen thermometer is best here, or test by dropping a tiny bit of batter in – it should sizzle immediately.

Carefully unwrap the well-chilled Mars bar. Dip it completely into your prepared batter, ensuring every inch is thoroughly coated. Allow any excess batter to drip off for a moment before frying.
- 5
Gently lower the battered Mars bar into the hot oil. Fry it for just 2-3 minutes, turning it once halfway through, until the batter is beautifully golden brown and delightfully crispy on all sides. It should look puffed up and inviting.
- 6
Using a slotted spoon, carefully lift the deep-fried Mars bar from the oil and place it onto a plate lined with paper towels. This helps to absorb any excess oil, leaving you with a perfectly crisp treat.
- 7
Serve your deep-fried Mars bar immediately, while it's still warm and the chocolate is wonderfully melted and gooey inside. For an extra touch of sweetness, you could dust it lightly with icing sugar or serve alongside a scoop of vanilla ice cream.
Frequently Asked Questions
What kind of Mars Bar should I use for the best results, and should it be chilled?+
A standard-sized Mars Bar is ideal. Freezing it for at least 30 minutes beforehand is crucial to prevent it from melting too quickly during frying, ensuring a molten interior without total disintegration.
What is the optimal oil temperature for frying, and how long should I cook the Mars Bar?+
Heat your oil to 170-180°C (340-350°F). Fry for only 2-3 minutes, or until the batter is golden brown and crispy, to achieve a perfectly melted interior without burning.
How can I prevent the batter from becoming soggy or the chocolate from oozing out excessively?+
Ensure your oil is at the correct temperature before frying; too cool oil will result in a greasy batter. Also, make sure the Mars Bar is thoroughly coated in batter and well-chilled or frozen to create a protective layer against premature melting.
Can I deep-fry other types of chocolate bars, or are there specific ones that work best?+
While a Mars Bar is traditional, many other chocolate bars can be deep-fried. Bars with solid caramel, nougat, or biscuit centers (like Snickers or Twix) often hold up well, but avoid bars that are mostly plain chocolate or very liquid-filled.
