Traditional South African Melktert (Milk Tart)

Melktert — The Classic South African Milk Tart

Melktert — literally "milk tart" in Afrikaans — is one of the oldest and most beloved desserts in South African culinary history. A delicate, creamy, cinnamon-dusted custard filling nestled in a crisp, buttery pastry shell, the Melktert has been made in South African kitchens since the earliest days of the Cape Colony, when Dutch settlers adapted their European custard tarts using the abundant milk produced by cattle at the Cape.

Every South African family has a slightly different Melktert recipe — and every family believes, with complete sincerity, that theirs is the correct one. Some use a baked filling set with eggs; others use a stovetop custard thickened with cornstarch and poured into a pre-baked shell. Both are authentic. Both are delicious. This recipe uses the stovetop method — it produces a silkier, creamier filling that many people find more satisfying than the baked version, and it is impossible to overcook.

A proper Melktert is not overly sweet. It should taste primarily of warm, full-cream milk and vanilla, with cinnamon providing a gentle aromatic top note. The pastry should be thin, short, and crisp — a contrast to the soft, trembling filling. Served cool or at room temperature, it is one of the most elegant, understated desserts imaginable.

Ingredients

Makes: One 23cm tart (8–10 slices)  |  Prep time: 30 minutes  |  Cook time: 25 minutes  |  Chilling time: 2–3 hours

For the short crust pastry:

• 1½ cups (185g) cake flour, plus extra for rolling
• ¼ cup (50g) icing sugar, sifted
• ¼ tsp salt
• 125g cold butter, cut into small cubes
• 1 large egg yolk
• 2–3 tbsp ice cold water

For the milk custard filling:

• 1 litre full-cream milk (do not use low-fat — the fat is what gives the filling its body and flavour)
• 1 cup (200g) white sugar
• 4 tbsp (40g) cornstarch (Maizena)
• 3 tbsp (30g) cake flour
• 3 large free-range eggs, beaten
• 2 tbsp butter
• 1 tsp pure vanilla extract
• ¼ tsp salt
• 1 stick cinnamon (for infusing the milk)

To finish: Ground cinnamon for dusting (essential)

Method

Make the pastry:

1. In a food processor (or by hand using your fingertips), combine the flour, icing sugar, and salt. Add the cold butter cubes and pulse (or rub) until the mixture resembles coarse breadcrumbs with some pea-sized butter pieces remaining — do not overwork it.
2. Add the egg yolk and 2 tablespoons of cold water. Pulse briefly until the dough just comes together. If it is still crumbly, add the third tablespoon of water. The dough should hold together when pressed but should not be sticky.
3. Turn onto a lightly floured surface, shape into a flat disc, wrap in cling wrap, and refrigerate for at least 30 minutes. Resting the pastry is non-negotiable — it relaxes the gluten and prevents shrinking during baking.
4. Preheat your oven to 190°C. Roll the chilled pastry on a floured surface into a circle slightly larger than your tart tin. Carefully transfer to the tin, pressing it gently into the corners without stretching. Trim the excess. Prick the base all over with a fork. Line with baking paper and fill with baking weights or dried beans.
5. Blind bake for 15 minutes, then remove the weights and paper and bake for a further 8–10 minutes until the pastry is golden and fully dry. Allow to cool completely before adding the filling.

Make the filling:

1. Pour the milk into a medium saucepan and add the cinnamon stick. Heat over medium heat until the milk just begins to steam and small bubbles appear at the edges — do not boil. Remove the cinnamon stick.
2. In a separate bowl, whisk together the sugar, cornstarch, flour, and salt. Add the beaten eggs and whisk until smooth — this prevents any lumps in the finished custard.
3. Gradually pour the hot milk into the egg mixture, whisking constantly — add it in a thin stream to temper the eggs gently (adding all the hot milk at once will scramble them). Pour the mixture back into the saucepan.
4. Cook over medium-low heat, stirring constantly with a wooden spoon or silicone spatula, reaching all corners of the pan. The custard will suddenly thicken — this happens quickly once it reaches temperature. Continue stirring for 2 minutes after it thickens to cook out the flour taste. Remove from heat.
5. Stir in the butter and vanilla extract until the butter is melted and incorporated. The filling should be thick, smooth, and glossy.
6. Pour immediately into the cooled pastry shell, smoothing the top gently. Allow to cool at room temperature for 20 minutes, then refrigerate uncovered for at least 2 hours until fully set and cold.
7. Just before serving, dust the entire surface generously with ground cinnamon — applied through a fine sieve for an even coating. This step is what makes a Melktert look like a Melktert.

Tips for a Perfect Melktert

• Full-cream milk only: The fat content of full-cream milk is essential to the body and flavour of the filling. Low-fat milk produces a thinner, less satisfying custard.
• Never stop stirring the custard: The moment you leave stovetop custard unattended, it catches on the bottom of the pan and burns. Keep stirring, especially once it begins to thicken.
• Serve it cool: Melktert is always served cold or at room temperature. A warm Melktert has a loose, almost liquid filling that has not set properly. The minimum chilling time is 2 hours; overnight is better.
• Crustless Melktert: Many traditional South African recipes make a crustless Melktert — the filling is poured directly into a greased pie dish and baked at 180°C for 25–30 minutes until just set. It is quicker and equally delicious, if less traditional in appearance.
