Mary Berry Boiled Orange Cake is a citrus loaf or round cake made by boiling whole oranges until soft, blending them into a purée, and mixing them directly into the cake batter. The result is a moist, flavour-packed cake with a dense yet tender crumb and deep orange notes running through every slice.
2 medium oranges (seedless preferred)
4 large eggs
200g caster sugar
250g self-raising flour
1 tsp baking powder
150g softened butter (or margarine)
Optional: 1 tsp vanilla extract or orange zest for extra aroma
Place the whole oranges into a saucepan and cover them with water. Bring to a boil, then simmer gently for about 1 hour until the oranges are soft and can be pierced easily.
Drain the oranges and allow them to cool slightly. Cut them into chunks, remove any seeds, and blend into a smooth purée with the peel included.
Line a loaf tin or round cake tin with baking parchment and lightly grease the sides for easy removal.
Heat your oven to 160°C (fan) or 180°C (conventional) for an even bake.
In a bowl, whisk together the eggs and caster sugar until pale and fluffy. Add the softened butter and mix until smooth. Stir in the orange purée, then fold in the self-raising flour and baking powder gently to avoid losing air.
Transfer the batter into the prepared tin and smooth the surface with a spatula.
Bake for 45–55 minutes, or until a skewer inserted into the centre comes out clean. The moisture content may mean the cake takes slightly longer, so check from 45 minutes.
Allow the cake to cool in the tin for 10 minutes, then transfer to a wire rack to cool fully before cutting.
