Mix flour, cream cheese, and soft butter to form a shortcrust pastry. Wrap in foil and refrigerate for at least 3 hours or overnight.
Mix brown sugar, white sugar, and almonds together.
Sprinkle some of the sugar-almond mixture on your work surface. Roll out a portion of shortcrust pastry to the size of a cake.
Sprinkle the dough with the sugar-almond mixture. Divide into 12-14 triangles using a cake divider (or cut into a circle with a springform rim and then cut into pieces with a long knife).
Roll each triangle from the wider side into a croissant shape. Place seam-side down on a baking sheet lined with baking paper.
Repeat steps 3-5 with remaining dough and filling until all is used (makes approximately 60 pieces total).
Bake at 180 °C (356 °F) using convection heat for 15-18 minutes until golden.
Cool completely at room temperature, then store in an airtight tin.
