Equipment
Method
- Heat the oven to 325°F.
- Lightly grease a 9-inch square metal pan with 1 teaspoon of the butter.
- Line the pan with parchment paper, leaving an overhang on two sides.
- Beat the remaining butter and the sugar in a large bowl until smooth and creamy, about 2 minutes.
- Mix in the vanilla.
- Add the flour and salt and mix on low just until the dough begins to clump.
- Fold in the cranberries and pistachios.
- Press the dough evenly into the prepared pan.
- Prick the surface all over with a fork.
- Bake for 35 to 40 minutes, until the edges are lightly golden and the top looks set.
- Cool in the pan for 10 minutes.
- Score into 16 squares with a sharp knife.
- Cool completely in the pan before lifting out with the parchment.
Notes
For neat squares, score the shortbread while it is still warm, then let it cool completely before lifting it from the pan. Store airtight in the refrigerator for up to 7 days; it freezes well for up to 2 months. For a gluten-free option, use a 1:1 gluten-free baking flour.
