Ingredients
Method
- Preheat oven to 170°C / 150°C fan / Gas 3. Grease and line a 900g loaf tin with parchment sling.
- Beat butter and brown sugar 4–5 minutes. Add eggs one at a time. Add vanilla, orange zest, and juice. Add marmalade — beat briefly. Small flecks of peel in the batter are correct.
- Sift in flour and baking powder. Add milk — fold gently. Fold in walnuts or chocolate chips if using.
- Spoon into tin — level surface. Bake 55–65 minutes until golden and skewer comes out clean. Cover after 40 minutes if browning too quickly. Cool in tin 15 minutes.
- Warm marmalade and orange juice in a small pan until liquid. Lift cake from tin onto a wire rack over parchment. Brush warm glaze over top and sides — two coats for a deeper, glossier finish. Cool completely.
Notes
Use thick-cut Seville orange marmalade — gives the most complex, most bittersweet flavour.
Soft light brown sugar suits marmalade — the molasses note complements the bittersweet character.
Flecks and threads of peel in the batter are correct — they give the characteristic appearance.
Apply glaze while the cake is still warm — two coats for a properly integrated, glossy finish.
This cake improves over 2–3 days — make it ahead whenever possible.
Freeze without glaze for up to 3 months.
