Christmas Cake in the Air Fryer: A Small, Rich Fruit Cake in a 1lb Loaf Tin

I don't know about you, but in our house, any Christmas cake we get given is usually still sitting in the cupboard in February. It's always just a massive, foil-wrapped brick getting harder by the day, while nobody wants to admit they're completely over it. I've got three kids and not one of them will go near fruit cake. So there I am, eating it by myself with a cup of tea while everyone else stuffs their faces with chocolate.

It finally hit me: why on earth am I running the oven for three hours to bake a 1.5kg cake that only I eat? Fruit cake is heavy. A thin slice is plenty, and a little cake that actually gets finished by Boxing Day is way better than a giant one you're still chewing through in spring.

So, I tried chucking it in the air fryer.

Turns out, a standard 1lb loaf tin fits perfectly in most air fryer baskets. I already use one for banana bread, and fruit cake is honestly way harder to mess up than a standard sponge. It's dense, barely rises, and doesn't care what shape it takes. The only thing you actually have to worry about is getting the heat right.

Why a small one, and why the air fryer

Let's be real, most families just don't eat a huge Christmas cake anyway. A 1lb loaf cuts into about six to eight slices, which is all most of us actually want. (If you need more, just make two and give one away.)

As for the air fryer, it's just cheaper and faster. Instead of running a whole oven for three hours just for one tin, the air fryer does the job in a bit over an hour. Right now, with everyone watching their smart meters, that's basically the deciding factor between baking a cake or just buying one.

There are two catches, though. First, air fryer fans are aggressive. The top of your cake will burn way before the middle is cooked if you aren't careful, so you have to use foil and drop the temperature. Second, fruit cake needs low, slow heat. If your air fryer doesn't go below 160°C, you're going to have a tricky time and might be better off just using the regular oven.

(Also, if you're picturing a massive, traditional round cake with a festive ribbon... this isn't it. You'll need a deep round tin and a proper oven for that.)

The tin situation

I use a standard 20 x 10.5 x 6.5cm 1lb metal loaf tin. Don't use silicone. It blocks the heat and leaves the bottom all gummy. The tin needs to fit in the drawer with a finger's width of space all the way around. If it's jammed in tight, the air can't circulate, and you'll end up with a cake that's black on top and liquid in the middle. Forget about trying to squeeze a 2lb tin in there; even if it physically fits, it'll dry out terribly. (If you're not sure what your basket takes, what can you bake in an air fryer has the measurements.)

Ours are heavy carbon steel, non-stick made without PTFE or PFOA, with a 10-year guarantee, so the same tin does the Christmas cake, the banana bread and everything in between. Hand wash it and dry it straight away, which is pretty much the whole care guide for a loaf tin.

The mix (makes one small cake)

This is a quarter of our full-size Christmas cake recipe, so it tastes the same. Double it if you've got two tins.

• 100g currants, 65g sultanas, 65g raisins
• 25g mixed peel and 20g quartered glacé cherries
• 20g chopped blanched almonds
• 40ml brandy, dark rum, or sherry
• 55g softened butter and 55g dark muscovado sugar
• 1 large beaten egg
• 1 tsp black treacle
• 90g plain flour and ½ tsp mixed spice
• Zest of half an orange

First off, soak your fruit. Overnight is fine, a week is better. If you throw dry fruit into the batter, it'll suck all the moisture out of the cake. Just pour the booze over the fruit and peel, give it a stir, and leave it covered somewhere cool. (Going alcohol-free? Cold tea or orange juice works for the soak, but see the note on keeping further down.)

Quick tip from a bad year: if your dried fruit looks a bit shiny out of the packet, rinse it with boiling water first. They coat it in oil to stop it clumping, and if you don't wash it off, the cake comes out with a greasy middle that never cooks. I spent two years blaming my oven before I figured that out.

Also, don't swap the dark sugar and black treacle for lighter versions. Because the cake isn't cooking for three hours, it needs those dark ingredients for colour, otherwise it just looks like a pale tea loaf.

How to bake it

Fixing the burnt top, raw middle problem

Anyone who bakes in an air fryer knows this nightmare. It happens because the element blasts the top instantly while the dense middle takes ages to warm up. The fix is just dropping the temp to 140°C, getting that foil on at 30 minutes, and making sure there's space around the tin. If it still burns, your machine just runs too hot. Drop it to 130°C and add another 20 minutes.

(Oh, and wipe the basket out properly first, or your cake will taste like yesterday's chips.)

Feeding and finishing

To feed it, just poke a few holes in the top and spoon over two teaspoons of alcohol once a week. Don't go crazy, a small cake will turn to mush if you drown it. Keep it wrapped in paper, because foil straight on the cake reacts with the fruit and leaves weird grey marks.

Fed like that it'll keep for three months, so an October bake is fine for Christmas. If you went alcohol-free, don't feed it at all (juice goes mouldy), and either eat it within a couple of weeks or freeze it un-iced.

Decorating is dead easy on a loaf cake. Just brush with warm apricot jam, slap some marzipan and icing over the top, and tidy up the edges. Or do what I do: line up some almonds and cherries, glaze it with jam, and pretend you went for a minimalist look because you couldn't be bothered with icing sugar.

If you want a bigger one

If you'd rather have a proper 2lb cake, double the mix, but it's an oven job. A 2lb loaf tin is long and narrow, so the ends cook way before the middle. Line it with paper that stands a couple of centimetres above the rim, tie a double layer of brown paper round the outside (yes, like your gran did), and bake it at 140°C, or 120°C fan, for about two hours. Don't open the door for the first hour and a quarter, and test from 1 hour 45. Mine take around two hours to two hours twenty. Cool it in the tin overnight and feed it a tablespoon a week rather than two teaspoons. If you're choosing a tin, our loaf tin buying guide goes through the range.

The short version

I usually bake mine the first weekend of October. It's ready by December, tastes miles better than shop-bought, and because it's small, we actually finish it. That leaves December for the mince pies. And there's never any cake left in February, because there were only ever eight slices to begin with.
