Melt-in-your-mouth linzer cookies with a hint of vanilla, the best ever jam-filled cookies. Get a big batch ready, and your Christmas party will be a smashing success.
In a large bowl, sift the flour, add the powder sugar, baking powder and salt.
Add the egg, egg yolks, and vanilla extract and gently knead the dough.
Preheat the oven to 180 degrees C. (360 F)
Cut the dough in half, roll the first half with a rolling pin and use the cookie cutters of your choice.
Repeat the process with the remaining dough.
