Delicate buttery pastry, a moist walnut filling with rum, and a layer of quality dark chocolate create a classic treat with a subtle, balanced flavor. These cups are perfect for Christmas, family celebrations, or festive occasions, and their flavor deepens after resting.
The key to success is quality butter, several hours of chilling the dough, and gradually adding rum to the filling. This keeps the dough tender and prevents it from tearing during handling. If you’d like to vary the recipe, you can use hazelnuts, apricot jam, or a simple edible decoration.
What You’ll Need
For the dough:
- 200 g plain flour,
- 125 g soft butter,
- 50 g powdered sugar,
- 1 egg yolk,
- a bit of lemon zest, preferably from an organic lemon.
For the walnut filling:
- 200 g ground walnuts,
- 100 g ladyfingers, finely crushed,
- 200 g butter at room temperature,
- 100 g powdered sugar,
- rum as needed, just enough to bind the mixture,
- optionally a bit of cream if the filling is too thick.
For the chocolate topping:
- quality dark chocolate, ideally with 60–70% cocoa content,
- optionally 1 teaspoon of butter for a shinier chocolate surface.
The original recipe does not specify the exact amount of chocolate, so adjust according to the number of cups and your preferred decoration method.
Step-by-Step Preparation:
1. Preparing the dough: Combine soft butter with plain flour, powdered sugar, egg yolk, and a bit of lemon zest. Work the ingredients into a smooth, compact dough that doesn’t stick and holds together.
2. Chilling the dough: Wrap the prepared dough in cling film and let it rest in the fridge for several hours. The butter will firm up during chilling, making the dough less likely to tear, and the baked cups will be pleasantly tender.
3. Filling the molds: Gradually press the rested dough into the cup molds. Try to create an even layer so each piece bakes evenly and holds its shape well after unmolding.
4. Baking the cups: Bake the cups at 180 °C until golden, usually 8–12 minutes depending on the size of the molds. Keep an eye on the color while baking, as smaller pieces may be done sooner.
5. Cooling and unmolding: Let the baked shells cool completely before gently removing them from the molds. You can slightly twist the mold in your hand to release the cup more easily and avoid unnecessary breakage.
6. Preparing the walnut filling: Mix ground walnuts with finely crushed ladyfingers, butter at room temperature, and powdered sugar. Add rum gradually until you have a smooth, moist, and easily shapeable mixture.
7. Adjusting the consistency: If the walnut mixture is too thick, add a little more rum or a bit of cream. Incorporate the liquid carefully so the filling doesn’t become too runny and keeps its shape in the cups.
8. Filling the cups: Divide the prepared walnut filling into the completely cooled shells. Smooth the surface of each cup so the chocolate layer on top looks even.
9. Chocolate topping: Melt the dark chocolate in a water bath, making sure not to overheat it. For a shinier finish, you can stir in 1 teaspoon of butter. Gently dip the filled cups in the chocolate or pour the chocolate over them.
10. Setting and resting: Let the finished cups set and then store them in a cool place. They taste best after 24 hours, when the buttery pastry, rum walnut filling, and dark chocolate have melded together.
How to Properly Store Delicate Cups
Store the cups in a cool place in an airtight container to protect them from drying out and absorbing surrounding odors. You can separate the layers with baking paper to prevent the chocolate surfaces from getting damaged during storage.
Before serving, let them sit at room temperature for a short while to fully develop the buttery and nutty flavors. Although you can serve them once the chocolate has set, a 24-hour rest is recommended.
How to Adjust the Flavor of the Walnut Filling
You can add a spoonful of apricot jam to the filling for a pleasantly rounded flavor. For a milder version, use hazelnuts or a mix of different nuts. Always watch the consistency as you gradually add rum or cream.
Final Tip
For a more festive look, you can place a walnut or a piece of candied fruit on each cup before the chocolate sets completely. Keep the decoration simple to highlight the combination of delicate pastry, moist filling, and dark chocolate.
