Homemade Chilean Kuchen de Castañas Recipe
Preparation: 30 minutes
Cooking: 45 minutes
Servings: 6 people
Ingredients
Kuchen Dough
- 300 g (2 1/3 cups) of all-purpose flour
- 120 g (1/2 cup + 2 tablespoons) of sugar
- 100 g (7 tablespoons) of butter, melted
- 2 eggs
- 1 teaspoon of baking powder
Chestnut Cream
- 2 kg (4.4 lb) of chestnuts in their shells
- 450 ml (1 3/4 cups + 2 tablespoons) of milk
- 120 g (1/2 cup + 2 tablespoons) of sugar
- 3 tablespoons of cornstarch
- 1/2 cup of walnuts
- 1/2 cup of almonds
Instructions
- Place the chestnuts in a pressure cooker, cover them with water, and cook for about 30 minutes from the boil. Remove carefully and let cool. Peel the chestnuts down to the pale flesh inside. Put them in a blender or use a hand blender with one cup of the milk and process until smooth.

- In a nonstick pot, heat the sugar over medium heat until it melts, without stirring. Add the puréed chestnuts, the rest of the milk, and the cornstarch dissolved beforehand, stir with a wooden spoon, and cook until smooth and slightly thick.

- In a large bowl, beat the melted butter, add the sugar and eggs, mix well, then add the flour and baking powder and knead until the dough no longer sticks to your hands. Press it evenly into an oiled kuchen tin, including the sides, and prick it with a fork so it does not puff up.

- Bake at 180 C (356 F) for about 10 minutes. Remove, spread the filling evenly over the base, scatter the almonds and walnuts on top, and bake for 10 more minutes or until golden. Let cool to room temperature and serve as a dessert or with afternoon tea.
Additional Tips
Use ready-cooked chestnuts
Vacuum-packed cooked and peeled chestnuts, sold in some supermarkets and gourmet shops, make the cream much faster.
Let it rest
Refrigerate the kuchen for at least 4 hours, ideally overnight, so the filling sets and the flavor deepens.
Do not overwork the dough
Knead only until it comes together, so the base stays tender.
| Original ingredient | Substitute | Ratio | Flavor note |
|---|---|---|---|
| Fresh chestnuts | Vacuum-packed cooked chestnuts | About 800 g | Much faster |
| All-purpose flour | Rice flour and cornstarch (2:1) plus extra baking powder | 1:1 | Gluten-free, more crumbly |
| Walnuts and almonds | Hazelnuts | 1:1 | More aromatic |
| Whole milk | Evaporated milk | 1:1 | Creamier filling |
Frequently Asked Questions (FAQs)
1. How do I keep the dough from getting hard or dry?
Do not overwork it and prebake it for only 10 minutes before adding the filling. You can also use cold butter worked in quickly with the dry ingredients.
2. Can I use whole wheat or gluten-free flour?
Whole wheat flour works for a more rustic version, though denser. For gluten-free, mix 200 g of rice flour with 100 g of cornstarch and add 1 extra teaspoon of baking powder.
3. How do I peel chestnuts easily?
Peel them while still warm after cooking, removing both the hard shell and the thin inner skin.
4. How long does it keep?
Refrigerated and covered, it keeps well for 3 days.
What Is Kuchen de Castañas?
Kuchen de castañas is a Chilean kuchen filled with a thick chestnut cream, a heavier, autumnal cousin of the fruit kuchens made in the south of the country.
History and Origin
Chestnut kuchen reflects the German heritage of southern Chile, where the chestnut tree (Castanea sativa) adapted perfectly to the rainy climate, and recalls the pastry of Central Europe.
Did You Know?
Because the chestnut filling is richer than fruit fillings, chestnut kuchen is usually served in smaller slices than other kuchens.
