Preheat oven to 180°C (360°F).
Mix the flour, vanilla sugar, baking powder, pinch of salt, sugar and soft butter in a bowl. Sand the mixture with your fingers until you obtain a sandy texture.
Add the egg yolks and gather the dough into a ball without kneading. To homogenize, fold it twice against the work surface, then gather into a ball.
Shape small balls of dough, flatten them slightly to the diameter of the silicone moulds, and place them in the moulds.
Flatten the surface well and, if necessary, even out with the back of a small, slightly damp spoon.
Bake for about 10 minutes, until golden brown.
As soon as they come out of the oven, while they are still warm and malleable, make a hollow in the center of each tartlet. Use your thumb or a clean cork.
Fill the hollows with caramel using a piping bag or a freezer bag for greater precision.
Unmould the tartlets and leave to cool on a wire rack.
Your Krumchy are ready to be decorated or eaten as they are!
How to decorate your Krumchy mini tarts?
You have 3 options :
1 . Cover the entire top with chocolate
Melt the chocolate in a double boiler until smooth.
Place a teaspoon of melted chocolate in the center of each tartlet.
Gently spread with the back of a spoon, using circular movements so the chocolate reaches the edges.
Tap the tartlet lightly on the table to smooth the chocolate if a small point remains visible.
Add the finishing touch with crushed toasted hazelnuts for a crunchy, elegant finish.
2. Cover just the hollow with chocolate :
Add 1/2 teaspoon of melted chocolate to cover the hollow containing the caramel.
Add a toasted hazelnut to the center for the perfect finish.
3. Do not cover with chocolate :
Fill the hollows containing the caramel with walnut kernels for a more rustic, crunchy version.
These 3 variations add a different, but equally delicious, touch to your tarts.
