Ingredients
- 125 g Unsalted butter (Cold, cut into cubes)
- 60 g Powdered sugar
- 1 Egg (For the dough, plus 1 yolk for glazing)
- 200 g T55 flour
- 50 g Almond powder (Divided: 30 g in the dough, 20 g for the center)
- 1 pinch Fleur de sel

- 200 ml Heavy cream (Cold, to whisk)
- 20 g Granulated sugar (For the whipped cream)
- 1 pinch Ground cinnamon (To decorate the whipped cream)
Instructions
Prepare the sweet pastry dough
In the mixer bowl (or a bowl), mix the cold butter cut into cubes with the powdered sugar until a creamy consistency is achieved. Add the egg, then incorporate the flour, almond powder and the pinch of sea salt. Mix until the dough comes together into a homogeneous ball.
Time: PT5M
Rest in the refrigerator
Form a ball with the dough, wrap it in plastic film and place it in the refrigerator for 1 hour.
Time: PT1H
Slightly soften the dough
Remove the dough from the refrigerator 15 minutes before using so it becomes more pliable for rolling.
Time: PT15M
Roll out and cut the dough
Lightly flour the work surface. Divide the dough into small pieces the size of an apricot (about 30 g each). Roll each piece to a thickness of about 3 mm.
Time: PT10M
Fill the tartlets
On each disc, sprinkle 20 g of almond powder in the center, leaving about 3 cm of free edge. Distribute the fresh blackberries over the almond powder. Fold the edges toward the center and press lightly to seal.
Time: PT10M
Glazing and finishing
Beat an egg (or just the yolk) and brush the edges of the tartlets with a brush. Sprinkle the edges with a small amount of brown sugar.
Time: PT3M
Bake
Place the tartlets on a tray lined with parchment paper or a Silpat. Bake in a pre‑heated oven at 180°C for 20 minutes, or until the edges are golden and the dough is cooked.
Time: PT20M
Temperature: 180°C
Prepare the whipped cream (optional)
Whisk the very cold heavy cream with the granulated sugar until a firm consistency is achieved. Transfer to a piping bag fitted with a star tip.
Time: PT7M
Final plating
Place a small cloud of whipped cream on each tartlet using the star tip, then sprinkle with a pinch of ground cinnamon.
Time: PT3M

Critical Steps — Do Not Skip
- Form a homogeneous dough without over‑working it.
- Respect the refrigeration resting time (1 h) and the pre‑rest of 15 min.
- Do not overload the tartlets with blackberries to avoid soggy dough.
- Brush the glaze properly to obtain a beautiful color.
- Bake at 180°C for 20 minutes, monitor the coloration.
Chef Tips from the Video
- Lightly dust the cooled tartlets with powdered sugar for an elegant finish.
- Replace blackberries with a mix of red berries to vary the flavors.
- Add a hint of lemon zest to the dough for a fresh note.
Troubleshooting
The dough cracks when folding the edges.
Let the dough rest an additional 5 minutes at room temperature or add a teaspoon of cold water.
The tartlets are soggy after baking.
Increase the amount of almond powder in the center or slightly reduce the amount of blackberries.
The whipped cream does not rise.
Use very cold cream, whisk in a pre‑chilled bowl and do not exceed a firm consistency.
Storage
Refrigerator: Store the tartlets in an airtight container for 2 to 3 days. The whipped cream should be kept separately.
Freezer: Can be frozen without the whipped cream, up to 1 month. Reheat at 150°C before serving.
Room temperature: Consume the same day if left at room temperature for less than 2 hours.
Make-Ahead Tips
- Prepare the dough the day before and keep it refrigerated.
- Whipped cream can be made ahead and kept chilled, covered with plastic wrap.
- Tartlets can be baked ahead and reheated in the oven before serving.
