Add all the dough ingredients in a food processor and pulse until everything comes together in chunks. Divide the dough into 2, form each piece into a ball and wrap tightly with a cling film. Chill in the fridge for 2 hours.
Add all of the filling ingredients, except for jam, into a blender and blend into a semi fine mixture. Set aside.
Place 1 dough on a floured surface. Roll into a 9 inch (23 cm) circle.
Spread a very thin layer of jam on top. Sprinkle ½ of the filling evenly. Lightly press the filling with your hands. Using a pizza cutter, cut the circle into 8 equal triangles.
Starting from the outer side, roll a triangle into a crescent shape. Place on a baking tray with baking sheet, pointy side down. Continue with the rest.
Chill in the fridge for 20 minutes. After that gently brush with some egg wash. Bake in a preheated oven at 350ºF (175ºC) for 25 minutes or until golden brown and fully cooked. Cool completely. Dust with some icing sugar and enjoy!
