Delia Smith Rock Cakes Recipe

If you love old-fashioned British baking, these rock cakes are the sort you’ll want on repeat. They’re craggy and golden on the outside, soft and cakey in the middle, with sweet little bursts of dried fruit and a gentle, buttery richness. This is a straightforward, beginner-friendly bake with no fancy equipment, just a bowl, a fork, and a baking tray. From start to finish, you’re looking at about 30 minutes.

Ingredients

For the rock cakes

• 250g self-raising flour
• 1 tsp baking powder
• Pinch of fine salt
• 75g unsalted butter, cold and cut into small cubes
• 100g caster sugar
• 150g mixed dried fruit (sultanas, currants, raisins, or a mix)
• 1 tsp mixed spice (optional, but lovely)
• 1 large egg
• 2 to 3 tbsp milk, as needed

To finish (optional)

• 1 to 2 tbsp demerara sugar, for a crisp, sparkly top

How to Make Delia Smith Rock Cakes Recipe

Oven preparation

• Prepare the oven: Preheat the oven to 200°C or 180°C fan. Place a shelf in the middle of the oven so the cakes bake evenly and colour nicely.
• Prep your tray: Line a large baking tray with baking paper. Rock cakes spread a little, so leave space between each one.

Mixing

• Rub in the butter: In a large bowl, mix the flour, baking powder, and salt. Add the cold butter and rub it in with your fingertips until you have a rough breadcrumb texture.
• Add the sweet bits: Stir in the caster sugar, dried fruit, and mixed spice (if using) until evenly distributed.
• Bring it together: Beat the egg with 2 tablespoons of milk, then pour into the bowl. Use a fork to mix into a stiff, slightly sticky dough. If it looks dry and won’t come together, add a splash more milk, a teaspoon at a time.

Baking

• Portion the dough: Spoon the mixture into 12 rough heaps on the tray. Don’t smooth them out. The rugged top is exactly what you want.
• Optional finishing touch: Sprinkle with demerara sugar for a crisp top and a bit of crunch.
• Bake: Bake for 12 to 15 minutes, until golden and set. They should feel firm on top, not sticky or wet.

Cooling

• Set before moving: Leave the rock cakes on the tray for 5 minutes so they firm up and don’t break when lifted.
• Cool completely: Transfer to a wire rack to cool. They’re excellent slightly warm, but they’ll slice and store better once fully cool.

Assembling and serving

• Serve: Enjoy as they are, or split and spread with butter for a very traditional tea-time treat.

Tips

Why did my rock cakes turn out hard?

Overmixing and too much flour are the usual culprits. Mix with a fork just until the dough comes together, and avoid packing flour into the measuring cup if you’re not weighing. Also check your bake time, as a couple of extra minutes can dry them out.

How do I get the classic craggy “rock” top?

Keep the dough stiff and use two spoons to drop rough heaps onto the tray. Don’t flatten or smooth the tops, and don’t add too much milk or the mixture will slump.

What if my mixture is too dry and won’t come together?

Add milk gradually, a teaspoon at a time, mixing with a fork between additions. You want a stiff dough that holds its shape, but doesn’t have dry flour hiding at the bottom of the bowl.

How do I stop the fruit sinking or clumping?

Toss the dried fruit through the flour mixture before adding the wet ingredients. If your fruit is very sticky, a quick dusting of flour helps it separate so every cake gets a good spread.

Serving Suggestions

• With tea or coffee, served slightly warm
• Split and buttered for an extra-indulgent bite
• Alongside fresh berries for a light afternoon treat
• Packed into lunchboxes once fully cooled

Storage

Room temperature

Store rock cakes in an airtight container for up to 3 days. If your kitchen is warm, add a sheet of kitchen paper to the container to help manage moisture.

Refrigerator

I don’t recommend refrigerating them, as it tends to dry the crumb. If you must (very warm weather), keep them well wrapped and bring to room temperature before serving.

Freezing

Freeze in a sealed container or freezer bag for up to 3 months. Defrost at room temperature for 1 to 2 hours. For a just-baked feel, warm in a 160°C oven for 5 minutes.

Classic British rock cakes with a rough, craggy top, a soft crumb, and plenty of sweet dried fruit. Quick to mix, easy to bake, and perfect with a cup of tea.

Ingredients

• 250g self-raising flour

• 1 tsp baking powder

• Pinch of fine salt

• 75g unsalted butter, cold and cut into small cubes

• 100g caster sugar

• 150g mixed dried fruit (sultanas, currants, or raisins)

• 1 tsp mixed spice (optional)

• 1 large egg

• 2–3 tbsp milk, as needed

• 1–2 tbsp demerara sugar, for sprinkling (optional)

Directions

• Preheat the oven to 200°C (180°C fan). Line a baking tray with baking paper.
• Mix the self-raising flour, baking powder, and salt in a bowl. Rub in the cold butter with your fingertips until the mixture resembles rough breadcrumbs.
• Stir in the caster sugar, dried fruit, and mixed spice (if using).
• Beat the egg with 2 tbsp milk, then add to the bowl. Mix with a fork to a stiff, slightly sticky dough. Add a splash more milk if it looks too dry.
• Spoon 12 rough, craggy heaps onto the tray, spacing them apart. Sprinkle with demerara sugar if you like.
• Bake for 12–15 minutes until risen and golden, with no wet batter showing.
• Cool on the tray for 5 minutes, then transfer to a wire rack to finish cooling.

Notes

• Keep the dough rough when you portion it. That craggy surface is the classic rock cake look.
• Mix with a fork, not a spoon, and stop as soon as there are no dry patches.
• If your dried fruit is very dry, soak it in hot water for 10 minutes, then drain and pat dry before using.
