Taken from An Italian in my Kitchen. Makes a really nice cookie for tea!

Ingredients

• 1 cup salted butter softened
• 1/4 cup granulated sugar
• 1/2 cup powdered sugar
• 1 pinch salt (if you use unsalted butter then add 1/4 teaspoon of salt)
• 2 egg yolks (room temperature)
• 2 cups all purpose flour
• 1/2 teaspoon vanilla
• Extra Egg Wash
  • 1 medium egg
  • 1 tablespoon milk
  • 1/4 - 1/3 cup sparkling or granulated sugar

Steps

• In a big bowl
  • cream the butter
  • then add the sugars and salt
  • Add egg yolks and vanila
• Make sure it’s all well combined and scrape the bowl
• Add the flour in 3 additions
• Mix the dough until just combined
• Place the dough on a lightly floured surface
  • knead gently into a ball
  • separate the dough into 2 parts
  • They can be a log to cut into rounds or a ball to shape later
  • Wrap the dough in plastic and fridge for at least 3 hours
• Remove the dough from the fridge
• For the log
  • Brush with egg wash
  • sprinkle with sparking sugar
  • cut into 1/3” slices
  • place on a parchment paper lined cookie sheet
• For cut out cookies
  • Roll the dough on a lightly floured surface
  • Not too thin, this will make the cookies delicate and burn more easily
  • Cut out your with favorite cookie cuters :)
  • Place the cut outs on a parchement lined cookie sheet
  • Sprinkle with sparkling sugar or granulated sugar
  • No egg wash needed
• Refrigerate the cookies again while the oven is pre-heating at 325F (160C)
• Once the oven is ready bake the cookies 15-17 minutes or until the cookies are light brown on the bottom and lightly golden around the edges but still pale on top
• After 2-3 minutes carefully remove the cookies with a metal spatula from the cookie sheet and carefully place a wire rack to cool completely
