A Cake That Lives in Every Scottish Granny's Recipe Book

If you grew up in Scotland, there's a decent chance you've eaten this cake without ever knowing its name. It was just "the loaf" sitting on the kitchen worktop, wrapped in foil, waiting to be cut into. Sultana loaf cake has been a fixture of Scottish baking for generations, the kind of recipe passed down on handwritten index cards, scribbled in the margins of old Be-Ro books, and committed to memory after making it so many times the instructions became pointless.

It's a simple sponge, no drama, no fancy technique required. Creamed butter and sugar, eggs folded in carefully, self-raising flour to lift it, and a generous handful of plump sultanas running through every slice. The genius of it is how satisfying it is for how little effort goes in. You can have it mixed and in the oven inside twenty minutes.

Getting the Best Out of a Simple Bake

The one step that makes a real difference here is soaking the sultanas briefly in warm tea before you start. Even fifteen minutes in a mug of strong breakfast tea and they plump right up, giving the finished cake a noticeably more moist and juicy texture. Drain them well and toss them in a tablespoon of flour before folding into the batter: that flour coating stops them sinking to the bottom during baking, which is a common frustration with fruit cakes.

Bake this low and slow. A conventional oven at 160°C (140°C fan) is the right temperature. Go too high and the outside sets before the centre has had a chance to rise properly. The idea is a steady, even bake over about an hour, producing a cake that's golden on top, cooked through, and still moist inside. A skewer pushed into the centre is your best friend here: if it comes out clean, the cake is done. If it comes out with wet batter clinging to it, give it another ten minutes and check again. Don't be tempted to rush it.

One more thing: don't overmix the batter once you've added the flour. Fold it in gently with a large spoon or spatula. Overworking the gluten makes the cake dense and, worse, crumbly when you try to slice it. Stop as soon as you can't see any dry flour.

How to Serve It

Cut it into thick slices and serve it just as it is, or spread with a little salted butter. A cup of tea alongside is non-negotiable. It keeps well in an airtight tin at room temperature for up to three days, though in most households it rarely sees out a second day. It also freezes nicely: slice it first, wrap each piece individually, and you've got a ready supply of something decent to put on the table when someone turns up unexpected.

Ingredients

• 200g sultanas
• 150ml strong breakfast tea, hot (e.g. 2 teabags steeped for 5 minutes)
• 130g unsalted butter, softened to room temperature
• 130g caster sugar
• 1 tsp finely grated lemon zest
• 2 large eggs, beaten
• 200g self-raising flour, sifted
• 1 tbsp plain flour (for tossing the sultanas)
• 1-2 tbsp whole milk, if needed
• Pinch of fine sea salt

Method

1. Place the sultanas in a bowl and pour over the hot tea. Leave to soak for 15-20 minutes until plump, then drain through a sieve and pat lightly with kitchen paper to remove excess moisture. Set aside.
   
2. Preheat your oven to 160°C (140°C fan / Gas Mark 3). Grease a 2lb (900g) loaf tin and line it with baking parchment or a loaf tin liner, leaving a little overhang on the sides so you can lift the cake out easily.
3. In a large mixing bowl, beat the softened butter, caster sugar, and lemon zest together with an electric hand mixer or wooden spoon until the mixture turns pale and noticeably lighter in texture, about 3-4 minutes. Scrape down the sides of the bowl halfway through.
   
4. Add the beaten eggs gradually, a little at a time, mixing well between each addition. After the first addition, stir in a tablespoon of the sifted self-raising flour to help prevent the batter from curdling. Continue adding the egg until it is all incorporated.
5. Add the pinch of sea salt, then sift in the remaining self-raising flour. Using a large metal spoon or flexible spatula, fold the flour into the batter with gentle cutting and folding motions. Stop folding as soon as no dry flour remains. Do not overmix.
   
6. Tip the drained sultanas into a small bowl and toss them in the tablespoon of plain flour until lightly coated. Shake off any excess, then fold the sultanas evenly through the cake batter. If the batter feels very stiff and dry, add 1-2 tablespoons of milk to loosen it slightly. It should be thick but drop reluctantly from the spoon.
7. Spoon the batter into the prepared loaf tin and smooth the top with the back of a spoon or offset spatula. Give the tin a gentle tap on the worktop to knock out any air pockets.
   
8. Place in the centre of the preheated oven and bake for 55-65 minutes. The loaf is ready when it is well-risen and deep golden on top, and a skewer or thin knife inserted into the middle comes out completely clean. If the top is browning too quickly, lay a sheet of foil loosely over the tin for the last 15 minutes.
9. Remove from the oven and leave the cake to cool in the tin for 10 minutes before lifting it out using the parchment overhang. Transfer to a wire rack to cool completely before slicing. Cutting it while still warm can cause it to crumble.
