Cut the puff pastry into squares and place on a baking sheet lined with baking paper. Put 1 tablespoon of jam in the middle. Now cut into the corners of the square - up to the jam - and then knock in the outer corners towards the center. This is how the wind turbines are made.
Then bake the windmills for approx. 10 - 15 minutes in a preheated oven at 200 ° C (or follow the instructions on the package) (varies depending on the oven).
Dust with powdered sugar immediately after baking. This creates a thin and sweet frosting.
We prefer to eat the wind turbines while they are still lukewarm.
