Nutella Hamantashen

Directions

1. 1
   Preheat the oven to 325*.
2. 2
   Combine all of the dough ingredients in the bowl of an electric stand mixer fitted with the dough hook. (Start with 5 1/2 cups of flour and work your way up to 7 if you need it.) Mix the dough for a few minutes until it's well combined and not at all sticky. (Add flour as needed.)
3. 3
   Divide the dough into about four even balls. Working with one ball at a time, roll the dough about 1/3 inch thick. Cut it into 3-inch rounds using cookie cutter, glass, or any other round object you have in your kitchen.
4. 4
   Place some filling in the center of each circle. - For Nutella or jam, use about a teaspoon per cookie. - For chocolate chips, use about 5 chips. - For cinnamon sugar, gently press finger down in the center of the dough circle to make a small indentation. Then put about 1/4 teaspoon of cinnamon-sugar in the 'hole.'
5. 5
   Form the rounds into triangles by pinching the corners closed.
6. 6
   If you want glossy shiny cookies, make an egg wash by beating one egg yolk with a little water. Brush the cookies with the egg wash before baking for 15-20 minutes until golden. Cool for at least 15 minutes on the tray and then transfer to racks to cool completely. Eat within a few days or freeze for later.
