Mrs Robin’s boiled fruit cake is the sort of old-fashioned bake that’s passed down a family rather than copied from a book. It’s a one-pan, one-bowl method — dried fruit, sugar, margarine and water simmered briefly together before the flour and eggs go in — which makes it forgiving, reliable, and easy enough to bake on a weeknight. The full ingredients, timings and step-by-step method are in the recipe card below.

Mrs Robin’s Fruit Cake
Ingredients
- 125 g margarine
- 175 g sugar (dark brown, light or white)
- 175 g currants
- 175 g sultanas
- 50 g candied peel
- 225 ml water
- 1 tsp bicarbonate of soda level
- 1 tsp mixed spice heaped
- 2 eggs beaten
- 125 g plain flour (whole wheat or white)
- 125 g self-raising flour (whole wheat or white)
- 1 pinch salt
Instructions
- Place the margarine, sugar, currants, sultanas, candied peel, water, bicarbonate of soda and mixed spice in a pan. Bring to the boil, then simmer for 1 minute.
- Pour into a large mixing bowl and leave to cool to room temperature.
- Line an 18cm square or 20cm round tin (or a loaf tin, if you prefer) with greased greaseproof paper.
- When the mixture is cool, add the beaten eggs, both flours and the salt. Mix well, then pour into the tin and give it a little shake so the mixture settles into the corners.
- Bake in the centre of a moderate oven (180°C / gas mark 4) for 1 hour 15 minutes, until a skewer inserted into the centre comes out clean. Cool in the tin, then transfer to a wire rack. The cake improves if left to stand for a day or two after cooking — if you can wait that long.
Notes
Tips and variations
This is a really old boiled-cake recipe which is great for using up whatever dried fruit you have left over. You can swap around the currants, sultanas and candied peel as long as you keep the overall weight the same — raisins, glacé cherries, chopped dates and dried apricots all work well.
The cake improves if left to stand for a day or two after cooking — if you can wait that long. Wrap it in greaseproof paper then foil and keep it in an airtight tin at room temperature. It will keep well for up to a week, and it also freezes beautifully for up to three months.

Linda's kit list for this cake
This recipe calls for an 18cm square or 20cm round tin (a loaf tin works too). Here are the deep, loose-bottomed tins we'd use, plus the bits that make a long, slow bake easy:
-
MasterClass 18cm Square Loose-Bottom Deep Cake Tin
The 18cm square the recipe suggests — a deep, loose-bottomed tin lifts a boiled fruit cake out cleanly. MasterClass is a long-standing British baking staple.
