How to Make Cozonac: Romania's Festive Sweet Bread

Cozonac is more than just a sweet bread in Romania—it is a symbol of celebration, family gatherings, and tradition. This rich, braided loaf, often filled with walnuts, poppy seeds, or Turkish delight, appears on tables at Easter and Christmas, and sometimes at weddings or baptisms. Making cozonac is a labour of love that fills the kitchen with the aroma of vanilla, rum, and citrus. While every family has its own recipe, the basic method remains consistent. Here is a guide to creating your own cozonac at home.

What Makes Cozonac Special?

Unlike everyday bread, cozonac is enriched with eggs, butter, sugar, and milk, giving it a soft, slightly sweet crumb. The dough is traditionally kneaded for a long time—sometimes by hand—to develop the gluten that creates its characteristic stringy, fluffy texture. It is often braided and filled with a rich mixture of ground walnuts, cocoa, and rum, or with poppy seeds and honey. Some versions include pieces of Turkish delight (rahat) or raisins. The result is a glossy, golden loaf that is as beautiful as it is delicious.

Ingredients

For one large cozonac, you will need:

• 1 kg strong white flour (plus extra for dusting)
• 500 ml warm milk
• 5 egg yolks (plus 1 whole egg for brushing)
• 200 g caster sugar
• 150 g unsalted butter, melted
• 50 ml vegetable oil
• 25 g fresh yeast (or 7 g dried yeast)
• Zest of 1 lemon and 1 orange
• 1 teaspoon vanilla extract
• 2 tablespoons dark rum
• A pinch of salt

For a walnut filling: mix 300 g ground walnuts, 150 g sugar, 2 tablespoons cocoa powder, 2 egg whites, and a splash of rum or milk to make a spreadable paste.

Step-by-Step Method

1. Activate the yeast by dissolving it in a little warm milk with a teaspoon of sugar. Let it sit for 10–15 minutes until frothy.
2. In a large bowl, combine the flour, sugar, and salt. Make a well in the centre and pour in the yeast mixture, remaining warm milk, egg yolks, melted butter, oil, lemon and orange zest, vanilla, and rum.
3. Knead the dough for at least 20–30 minutes by hand, or 10–15 minutes with a stand mixer fitted with a dough hook. The dough should be smooth, elastic, and slightly sticky but manageable.
4. Cover the bowl with a clean cloth and let the dough rise in a warm place for 1–2 hours, or until doubled in size.
5. Punch down the dough and divide it into two or three equal pieces, depending on how you want to braid it. Roll each piece into a rectangle, spread with the filling, and roll up tightly like a Swiss roll. Braid the rolls together if making a multi-strand loaf, or place them side by side in a greased loaf tin.
6. Place the shaped cozonac on a baking tray lined with parchment paper (or in a large loaf tin), cover, and let rise again for 45–60 minutes until puffy.
7. Preheat the oven to 180°C (fan 160°C). Brush the top of the cozonac with beaten egg for a shiny finish. Bake for 45–55 minutes, or until golden brown and a skewer inserted into the centre comes out clean.
8. Let the cozonac cool completely on a wire rack before slicing. It is best enjoyed fresh, but it keeps well for a few days wrapped in a clean cloth.

Fillings and Variations

While walnut is the most popular filling, you can experiment with other flavours. Poppy seed filling is made by grinding poppy seeds and cooking them with honey, milk, and a little butter. Some bakers add chopped Turkish delight or raisins to the walnut mixture for extra sweetness. For a simpler version, skip the filling and braid the dough plain, then sprinkle with pearl sugar before baking. No matter the filling, the key is a rich, well-kneaded dough.

Tips for Success

• Use room-temperature ingredients to help the yeast work effectively.
• Knead thoroughly—this is essential for the characteristic stringy texture.
• Be patient with the rising times; rushing will result in a dense loaf.
• If the top browns too quickly, cover loosely with aluminium foil during the last 15 minutes of baking.
• Cozonac freezes well, so you can make a double batch and save one for later.

Making cozonac is a way to connect with Romanian tradition and create something truly special for your family and friends. With practice, you will develop your own favourite filling and technique, and the aroma alone will bring everyone to the kitchen.
