Air Fryer Mars Bar

I went for lunch at a fish and chip restaurant in Spain in the summer of 2019. The food was delicious, and I am not a huge fish and chip shop fan.

So, you know it is good for me to eat it.

What amazed me, is that it was Scottish owned, and they did absolutely everything that you could think of and it went well beyond fish and chips.

There was battered haggis, battered black pudding and of course battered mars bars.

I mentioned this to Dominic, and we talked about how the everything battered is more a Scottish thing than a general British thing, but still makes a nice change to the classic fish and chip shop food.

Back home and I have become obsessed with how much of that Scottish fish and chip menu can be reinvented for the air fryer.

How we could make some of those battered delights in the air fryer and save a few calories along the way.

As this is Scottish week on Recipe This, I thought it would be perfect timing to take the battered mars bar to the air fryer.

What Is A Deep Fried Mars Bar?

But first, before we talk about converting the deep fried mars bar to the air fryer, I am sure you want to know what is a deep fried mars bar?

Well they are a popular sweet treat that you can mainly purchase in fish and chip shops. My husband Dominic who used to work as a chef, used to get regular orders for them and used to enjoy the deep fried mars bar himself.

They are the mars chocolate bar that have been covered in batter and then deep fried, using the batter that you would use for battered fish. A heart attack waiting to happen!!!

Where Do Deep Fried Mars Bars Come From?

The deep fried mars bar originated in Stonehaven, Scottland back in 1995. Two lads dared a fish and chip shop to make them one to see if it would taste good.

The deep fried mars bar then got the attention of journalists and before you know it, it was a thing throughout the United Kingdom.

Fast forward to 2020 and there are many fish and chip shops around the globe that sell the world famous battered mars bar.

It has travelled so far now, that you can get it in Australian fish and chip shops!

Converting The Deep Fried Mars Bar To The Air Fryer

Even though I love a deep fried mars bar at the chippy, it lacks a sweet flavour. The batter is meant for deep frying haddock and is not meant for the mars bar. The batter is also way too thick for most people.

That is why converting the deep fried mars bar to the air fryer and making your own pastry is ideal.

You can use the sweet version of my air fryer pie crust, like we did and then load a mars bar onto rolled out pastry and then cover the mars bar until you can no longer see it.

Then air fry it like you would do with other air fryer baked goods.

But the best thing is that shortcrust pastry (also known as homemade pie crust) is the perfect thickness for a battered mars bar.

That is because too thin like filo pastry and the caramel from the mars bar will fall out and too thick and the texture is all wrong.

What Ingredients & Gadgets Go Into Air Fryer Mars Bars?

Air Fryer Mars Bar Ingredients

There are 3 main ingredients that go into an air fryer mars bar:

I would recommend before making your air fryer mars bar that you have a good air fryer that will consistently make them for you. There seems to be some very cheap brands of air fryers that my readers keep complaining are breaking on them.

I recommend the Philips air fryer XL because of the quality and the fact that it is an air fryer that lasts. I would also recommend having an air fryer grill pan.

The reason I suggest a grill pan is that the grill pan works much better when cooking recipes that involve dough.

Otherwise, if you just use the air fryer basket it tends to stick to it and the food falls out. This can also make cleaning it a nightmare too!

My mars bar pastry made enough for 6 medium sized mars bars.
I used self raising flour in my pie crust, that way it will puff up a little which is perfect for the texture you want in a deep fried mars bar alternative.
