Mix the butter, cream cheese and sugar until frothy. Add flour and chopped pecans and stir in. Chill the dough for an hour. Then shape into rolls approx. 4 cm in diameter, wrap in foil and refrigerate overnight (if you don`t have this time, you can put them in the freezer for about 2 hours instead).
Preheat the oven to 175 ° C top / bottom heat.
Cut the dough rolls into about ½ cm thick slices and place them on a baking sheet lined with baking paper. Decorate each with a halved pecan nut.
Bake in the preheated oven for about 15 minutes until they turn lightly brown around the edges.
