200 grams ( = 7.05 ounces) soft butter (leave at room temperature til soft, do not heat in a microwave)
100 grams of sugar (1 cup US = 225 grams, so you need a little less than half a cup)
2 egg yolks
1 pinch salt
300 grams of all-purpose flour (2 cups) can be substituted with whole-grain flour
50 grams of ground hazelnuts (about 0.5 cups)
50 grams of ground almonds (about 0.5 cups)
Icing sugar and one package (1.5 tablespoons) vanilla sugar to dip the still-warm Vanillekipferl in. Please take a look at the note in the post.
Instructions
Combine all ingredients and mix into a dough. I let the KitchenAid Stand Mixer do this. It will be scrambled at first, but as the butter works in more, it forms into a nice dough. Put the dough in a plastic bag or wrap and refrigerate for at least half an hour.
Take the dough out of the fridge and knead small pieces until it softens a bit again, then form rolls approximately half an inch thick. Cut the rolls into 2- to 4-inch pieces, and bend each piece into a semicircle (like a croissant).
Bake at 350°F for about 15 minutes.
Mix the icing sugar with the vanilla sugar.
While still warm, coat them in a mixture of icing sugar and vanilla sugar.
