Traditionally made at Easter, also known in Bulgaria as kozunak, this sweet brioche-like loaf (it’s not really a sponge cake at all!) is similar to those of Italy, Austria and Poland.

It's adorned with a swirled filling, which varies depending on the region – with this chocolate/nut/rum filling it becomes a cozonac cu nuca.

Cook's notes

Oven temperatures are for conventional; if using fan-forced (convection), reduce the temperature by 20˚C. | We use Australian tablespoons and cups: 1 teaspoon equals 5 ml; 1 tablespoon equals 20 ml; 1 cup equals 250 ml. | All herbs are fresh (unless specified) and cups are lightly packed. | All vegetables are medium size and peeled, unless specified. | All eggs are 55-60 g, unless specified.


Makes: 2 loaves (about 16 slices)

Cooling time: 1 hour

Proving time: 2 hours

To make the dough, place the milk in a small saucepan and warm over low heat until lukewarm. Transfer about 60 ml (¼ cup) of the milk to a small dish and stir in the yeast and 1 teaspoon of the caster sugar. Set aside in a warm, draught-free place for 5 minutes or until frothy.

Meanwhile, combine the flour and salt in the bowl of a stand mixer fitted with a dough hook. Add the melted butter, eggs, remaining sugar, citrus rinds, vanilla and yeast mixture to the remaining milk and use a fork to whisk to combine evenly. With the mixer on medium speed, gradually add the milk mixture to the flour mixture and mix to form a soft dough. Continue to knead on low speed for 6-8 minutes or until the dough is smooth and elastic.

Lightly grease a medium bowl with the melted butter, add the dough and turn to coat the dough in the butter. Cover with plastic wrap and set aside in a warm, draught-free place for 1 hour or until doubled in size.

Meanwhile, to make the filling, combine the walnuts, sugar, cocoa, rum and lemon rind in the bowl of a food processor and process until well combined and the walnuts are finely ground and a coarse paste forms.
Brush two 11.5 cm x 20 cm (base measurement) loaf tins with melted butter to grease.

Punch the centre of the dough down with your fist and turn onto a lightly floured surface. Knead for 1-2 minutes or until reduced to its original volume.

Divide the dough into 4 equal portions (see Baker’s Tips). Use a lightly floured rolling pin to roll out a dough portion to a 20 cm x 25 cm rectangle. Sprinkle a quarter of the filling evenly over the dough and then press it gently into the dough. Starting from a long side, roll up the dough to form a log and enclose the filling. Repeat with the remaining dough portions and filling.

Twist two of the logs together and then place in a greased loaf tin. Repeat with the remaining dough logs to make another loaf. Cover with a slightly damp tea towel and set aside in a warm draught-free place for 1 hour or until almost doubled in size.

Preheat the oven to 190°C (170°C fan-forced).

Brush the tops of the loaves with the whisked eggwhite and sprinkle with the raw sugar. Bake for 20 minutes. Reduce the temperature to 160°C (140°C fan-forced) and bake for a further 20 minutes or until cooked through and the loaves sound hollow when tapped on the top. Stand in the tins for 5 minutes before turning onto a wire rack to cool (this will take about 1 hour).

Serve at room temperature, cut into slices.


Baker’s Tips

• You can also plait the dough logs together for a different appearance. Divide the dough into 6 equal portions in Step 8. Roll each to a 12 cm x 28 cm rectangle. Sprinkle each with one sixth of the filling before rolling and then plait 3 of the rolls together to make two loaves. Continue with the recipe.

• These loaves are best eaten the day they are made. They will however keep in an airtight container at room temperature for up to 3 days and is best served toasted.
