Ingredients
  

For the Shortbread
  • ¾ cup unsalted butter, softened (1½ sticks)
  • ¼ cup powdered sugar
  • ¼ cup granulated sugar
  • ¼ tsp salt
  • 1½ cups all-purpose flour
  • 2 tbsp Heath Bar toffee pieces, chopped
  • 2 tbsp shelled pistachios, finely chopped (heaping)

Method
 

Make the Dough
  1. Preheat your oven to 300°F
  2. In a large bowl, cream together the butter, powdered sugar, granulated sugar, and salt until smooth
  3. Stir in the flour until crumbs form, then knead until the dough comes together into a smooth ball
  4. Knead in the Heath Bar pieces and pistachios until evenly distributed throughout the dough
Bake
  1. Press the dough evenly into an ungreased 8-inch square baking dish. Smooth the top as much as possible — even thickness means even baking and prettier cookies
  2. Prick the dough all over with a fork, pressing nearly all the way through the dough
  3. Bake for 45–50 minutes until the top is golden and the edges are beginning to turn brown. For softer cookies remove at 45 minutes; for a crispier result go the full 50
Cut and Cool
  1. Immediately upon removing from the oven, slice the shortbread into 24 pieces — make 3 cuts in one direction and 5 perpendicular cuts, or 2 cuts and 7 for longer cookies. Use a pastry scraper or sharp knife, pressing straight down and lifting straight up without sliding to avoid tearing the warm cookies
  2. Leave the cookies to cool completely in the pan, then lift out with an offset spatula or butter knife

Notes

Cut the shortbread immediately out of the oven while it is still warm and soft — it will crumble if you wait until it cools. Press the knife or scraper straight down and lift straight up without dragging to keep the cuts clean. You can swap the Heath Bar and pistachios for other mix-ins — just keep the total amount roughly the same or it may affect the texture. The dough can easily be mixed entirely by hand with no electric mixer needed
