What is the secret to light, fluffy scones?

Handle the dough as little as possible. Rub the butter into the flour with your fingertips until it resembles breadcrumbs, then make a well and add the wet ingredients. Bring together with a knife, then gently pat (never roll vigorously) to about 2cm thick. Over-working develops gluten, which makes scones tough.

Should butter be cold or room temperature?

Cold butter, cut into small cubes. Cold butter creates small pockets in the dough that expand during baking, giving a lighter texture. Some bakers even freeze the butter and grate it in for the best results.

Why should I not twist the cutter?

Twisting the cutter seals the edges of the dough and prevents the scone from rising evenly. Press the cutter straight down and lift straight up for the tallest, most even rise.

How thick should the dough be?

About 2-2.5cm thick. Thinner dough gives flat scones, while thicker dough gives taller ones. Pat the dough gently to an even thickness — never use a rolling pin, as this overworks the dough.

Do I need to add baking powder with self-raising flour?

No. Self-raising flour already contains its raising agent (roughly 3-5g of baking powder per 100g of flour), so adding more over-leavens the dough — scones taste soapy and bitter, over-puff, then collapse. This calculator adds zero extra baking powder when you select self-raising flour. Only if you switch to plain flour does it add about 10g of baking powder per 225g of flour as a substitute.

Can I make scones with plain flour?

Yes — select 'Plain flour + baking powder' and the calculator adds about 10g baking powder per 225g flour to replace the raising agent that self-raising flour would have supplied. Add a small pinch of salt either way. Do not add this baking powder on top of self-raising flour, or the scones will over-rise and collapse.

How We Calculate This

This calculator scales the BBC Good Food classic British scone recipe. The base 225g recipe makes about 8 scones with the standard 5cm cutter. Because each scone uses dough in proportion to the cutter area (diameter squared), a larger cutter yields fewer, taller scones: about 6 with a 6cm cutter and 4 with a 7cm cutter from the same base dough.

Base Recipe (~8 Scones with a 5cm Cutter)

225g self-raising flour (no extra baking powder needed)
55g cold butter, cubed
25g caster sugar
150ml whole milk
1 large egg (for the egg-wash glaze)
Pinch of salt
Optional: 75g sultanas or raisins

Using plain flour instead? Add about 10g of baking powder per 225g of flour to replace the raising agent. Self-raising flour already contains this, so never add both.

Baking Tips
