Babà al Rum – Classic Neapolitan Rum Cake

Babà al Rum is the crown jewel of Neapolitan pastry, a pillow-soft leavened cake that drinks up a warm rum syrup until every bite is gloriously soaked and fragrant. Born in France and perfected in Naples over centuries, it is today an irreplaceable symbol of the city's pasticceria culture. One bite and you understand why Neapolitans call it a 'sublime sin'.

Babà al Rum – Classic Neapolitan Rum Cake

Ingredients

  • 300 g (2⅓ cups) strong bread flour (Manitoba)
  • 3 large eggs, room temperature
  • 100 g (7 tbsp) unsalted butter, softened
  • 10 g (2 tsp) fine salt
  • 30 g (2½ tbsp) caster sugar
  • 12 g (4 tsp) active dry yeast
  • 60 ml (¼ cup) whole milk, lukewarm
  • For the rum syrup: 500 ml (2 cups) water
  • 200 g (1 cup) caster sugar
  • 150 ml (⅔ cup) aged dark rum
  • 1 strip unwaxed lemon zest

Method

  1. Dissolve the yeast in the lukewarm milk with a pinch of sugar and let it stand for 10 minutes until frothy.
  2. Place the flour, sugar and salt in the bowl of a stand mixer fitted with the dough hook. Add the yeast mixture and eggs, and knead on medium speed for 10 minutes until the dough is smooth and starts pulling away from the sides.
  3. Add the softened butter a tablespoon at a time, waiting until each piece is fully incorporated before adding the next. Knead for a further 8–10 minutes until the dough is glossy, elastic and slightly sticky.
  4. Lightly butter 8 individual babà moulds (or a 24 cm / 9-inch savarin ring mould). Fill each mould no more than one-third full. Cover with cling film and leave to prove at room temperature until the dough rises to the rim — about 1 hour.
  5. Preheat the oven to 180 °C (350 °F) fan. Bake for 20–25 minutes until deep golden brown and a skewer inserted in the centre comes out clean. Unmould onto a wire rack and leave to cool completely.
  6. Make the rum syrup: combine the water, sugar and lemon zest in a saucepan and bring to a gentle boil, stirring until the sugar dissolves. Remove from the heat, discard the zest and stir in the rum.
  7. While the syrup is still hot (around 60 °C / 140 °F), submerge each babà in the syrup for 30–40 seconds, turning it gently, until it has absorbed the liquid and swelled noticeably. Place on a wire rack to drain briefly.
  8. Serve at room temperature, optionally topped with a spoonful of whipped cream (panna montata) and a maraschino cherry or a slice of fresh apricot.

Tips from the kitchen

💡 Use Manitoba (high-protein) flour: its strong gluten network is what gives babà its characteristic open, spongy crumb that soaks up syrup without collapsing.
💡 Do not rush the butter incorporation — adding it too quickly will break the dough structure. Patience here is the difference between a perfect babà and a dense one.
💡 The babà must be completely cool before soaking; a warm cake will disintegrate in the syrup. You can even bake them the day before and soak them the next day.

Frequently asked questions

Can I make babà al rum without a stand mixer?

Yes, but it requires effort. Work the dough by hand on a lightly floured surface, slapping and folding it for at least 20 minutes to develop the gluten, then incorporate the butter gradually. The dough will be sticky — resist adding extra flour.

How long does babà al rum keep?

Once soaked, babà keeps well covered in the fridge for up to 3 days; the rum actually helps preserve them. Unsoaked, baked babà can be stored in an airtight container for up to 5 days or frozen for a month — just soak them fresh when needed.

Can I reduce or omit the rum for an alcohol-free version?

Absolutely. Replace the rum with freshly squeezed orange juice, or use a mix of orange and lemon juice with a splash of vanilla extract. The result is a lighter, family-friendly dessert that Neapolitans sometimes call 'babà analcolico'.
