Mix oil, coconut sugar and orange juice until combined, then add egg, vanilla, baking powder, and salt. Mix. Add flour and mix until combined.

Roll out dough with a rolling pin between two pieces of parchment paper. With a cookie cutter or round glass cut dough into circles. Brush egg white on the dough circles. Place one teaspoon of jam/nut butter in the center of each circle. Fold and pinch the sides to create a hamentashen. Brush the outside with some more egg white to keep the corners from opening.

Bake in an oven preheated to 375 degrees Fahrenheit. Bake for nine minutes.
