Chelsea Buns date back to the 18th century in London, but Mary Berry’s version simplifies the traditional method without losing the charm. They are essentially a “tear-and-share” bake where a sheet of dough is spread with butter, sugar, and fruit, rolled up like a Swiss roll, and then sliced. The slices are packed snugly into a tin so they bake together, forcing the dough to rise upwards rather than outwards. The result is a soft-sided, pull-apart bun that is less crisp than a pastry but far richer than a standard bread roll.
Strong White Bread Flour (500g): You need the high gluten content of bread flour to give the buns their structure and chew.
Fast-Action Dried Yeast (7g / 1 sachet): Mary uses “easy-blend” yeast that goes straight into the flour—no need to activate it in water first.
Caster Sugar (60g for dough): Adds a subtle sweetness to the bread itself.
Butter (50g for dough, 50g for filling): Use unsalted butter. You will need melted butter for the dough and very soft butter for the filling.
Milk (300ml): Warmed slightly. This enriches the dough and softens the crumb.
Egg (1 large): Helps with the rise and color.
Dried Fruit (225g): A mix of currants and sultanas is standard.
Mixed Spice (1 tsp): The dominant flavor note.
Lemon Zest (1 lemon): Finely grated to cut through the sweetness.
Demerara Sugar (50g): For sprinkling inside the spiral to add a crunch.
Apricot Jam (for glazing): Melted and brushed on top for that sticky, shiny finish.
Prepare the dry mix: Put the flour, caster sugar, yeast, and a pinch of salt into a large bowl. Keep the salt and yeast on opposite sides of the bowl initially, as salt can kill yeast upon direct contact.
Mix the wet ingredients: In a jug, whisk the warm milk, melted butter (50g), and the egg together.
Form the dough: Pour the wet mixture into the flour. Mix with a rounded knife until it comes together, then get your hands in. It should be a soft, slightly sticky dough.
Knead well: Turn the dough onto a lightly floured surface. Knead for 10 minutes by stretching it away from you and folding it back. The dough should become smooth, elastic, and springy.
First rise: Place the dough in a lightly oiled bowl, cover with cling film or a damp tea towel, and leave in a warm place for about 1 hour, or until it has doubled in size.
Roll and fill: Punch the air out of the risen dough (knock back) and turn it out. Roll it into a large rectangle, roughly 30cm x 45cm. Brush the surface with the softened butter (50g). Sprinkle the dried fruit, lemon zest, mixed spice, and Demerara sugar evenly over the top.
Roll up: Starting from the long edge closest to you, roll the dough up tightly like a Swiss roll. You will end up with a long sausage shape.
Cut the buns: Trim the raggy ends. Use your sharp knife to cut the roll into 12 equal slices (about 4cm thick).
Second rise: Arrange the slices cut-side up in your greased roasting tin. Leave a little gap (about 1cm) between them—they will expand to touch each other. Cover and leave to prove again for 45–60 minutes until they are puffy and joined together.
Bake: Preheat the oven to 200°C (180°C Fan / Gas 6). Bake the buns for 20–25 minutes. They should be golden brown and sound hollow when tapped. If they brown too quickly, cover loosely with foil.
Glaze: While the buns are still warm, brush them generously with the melted apricot jam. Allow them to cool slightly before tearing them apart.
