Where Can You Buy a Deep Fried Mars Bar?

The most reliable place to find a deep fried Mars bar is a fish-and-chip shop in Scotland, particularly in the northeast. The Carron Fish Bar in Stonehaven is widely cited in local lore as the birthplace of the dish, and it continues to serve battered Mars bars to customers. Beyond Stonehaven, chip shops in Edinburgh, Glasgow, and Aberdeen have also offered the item, and a handful of outlets in London and other UK cities have introduced it as a novelty.

How to Make a Deep Fried Mars Bar at Home

The standard home recipe calls for a simple batter and a pot of hot oil. Recipes from multiple sources agree on the core ingredients and method, though variations exist for those who want a lighter texture.

What batter do you need?

Common batter ingredients across recipes include flour, egg, milk, sugar, salt, and baking powder. One variation adds corn flour and bicarbonate of soda to create a lighter, crispier coating. The Mars bar is typically chilled before dipping to help the batter adhere and to slow down the melting of the chocolate during frying.

How hot should the oil be and how long do you fry?

Recipes generally call for oil heated to roughly 350–370°F (about 200°C). The battered Mars bar is then lowered into the oil and fried for anywhere between 30 seconds and 4 minutes, until the batter turns golden brown. The wide time range reflects differences in batter thickness, oil temperature, and the size of the bar.

Can you air fry a Mars bar?

Yes, an air fryer can be used, but the texture will differ from the deep fried version. No dedicated air-fryer recipe with confirmed nutrition figures appears in the available sources, so home cooks should expect to experiment. A light batter or a thin coating of oil is recommended, and the air fryer should be set to around 180°C for 5–6 minutes. Because the method has not been standardised, results may vary.

How to deep fry a Mars bar without batter?

Some cooks skip the batter and fry the bar directly, but this is uncommon. Without batter, the chocolate melts rapidly and can leak into the oil, creating a mess and a different texture. The available sources all describe a battered version as the standard preparation.

For step-by-step instructions, Frymax offers a detailed recipe tailored to their frying oils. Other home cooks have shared their own methods on video platforms, with frying times and ingredient ratios that vary slightly.

How Many Calories Are in a Deep Fried Mars Bar?

Reported calorie counts differ considerably depending on the recipe, the amount of batter, the type of oil, and the serving size. No single authoritative figure exists, but a general range can be identified from the available data.

What the numbers say

One recipe lists 411 calories per serving, with 15.2g fat, 60g carbs, 10g protein, 31g sugar, and 4.9g saturated fat. Another source gives 725 kcal for a batch of 15 bars, which works out to roughly 48 kcal per bar — a figure that likely reflects a very small serving or a typo, and is not directly comparable. A video description claims “around 900 calories per bar,” while another source puts the number at 1200 calories for a deep fried Mars bar.

Why the numbers vary

The wide spread — from roughly 400 kcal to 1200 kcal per bar — reflects differences in batter thickness, oil absorption, and the size of the Mars bar itself. Thicker batter soaks up more oil, and longer frying times increase oil uptake. Without a standardised recipe, these figures should be treated as general estimates rather than exact values.

For comparison, a standard Mars bar (without batter or frying) contains about 230 calories. The batter and absorbed oil roughly double or triple that number, depending on the preparation.

The Origin of the Deep Fried Mars Bar

Where did the deep fried Mars bar originate?

One source states that it “originated out of Scotland” and was sold in some fish and chip shops. Another explicitly places its birth in Stonehaven and identifies the Carron Fish Bar as the birthplace in local lore. The exact name of the chip shop owner who first fried a Mars bar is not widely documented; multiple shops have reportedly claimed to have been first.
