1In a medium bowl mix egg yolks, philly cheese and baking powder using a hand held mixer. Carefully start adding the flour. When the mixture will not be mixing well, and will look like wood chips, put away the blending mixer and using your hands knead the dough.
2Create a roll and cover in foil and freeze for 15 minutes. At this time preheat the oven to 375.
3Take the dough out and separate into two. Roll and cut out 3 inch trangles.
4Make as many as you can and on centre of each put a small spoon of jam. Roll them into a croissant shape.
5Place the croissants onto a greased cookie sheet, and bake for 10-12 minutes or until golden.
6Repeat with the rest of the dough.
7When you take them out, put aside and sprinkle with powdered sugar on top.
