Cranberry Pistachio Shortbread Cookies

Ingredients

• 1 cup (2 sticks / 226g) Unsalted Butter, softened to room temperature
• 2/3 cup (80g) Confectioners’ Sugar (Powdered Sugar) (creates a more delicate, tender melt than granulated sugar)
• 1 tsp Pure Vanilla Extract
• 1/4 tsp Salt
• 2 cups (250g) All-Purpose Flour
• 1/2 cup Dried Cranberries, finely chopped
• 1/2 cup Shelled Pistachios, coarsely chopped
• 1 large Egg White (beaten, optional, for brushing the log edges before rolling in extra chopped pistachios)

Step-by-Step Instructions

1. Beat the Butter and Sugar: In a large bowl (or stand mixer fitted with the paddle attachment), beat the softened butter and confectioners’ sugar together on medium speed for about 2 minutes until smooth and creamy. Do not overwhip, as you don’t want to incorporate too much air.
2. Add Flavorings: Mix in the vanilla extract and salt until fully incorporated.
3. Combine the Flour: Reduce the mixer speed to low and slowly add the all-purpose flour, mixing just until the dough comes together and no dry streaks remain. (The dough will look crumbly at first, but keep mixing briefly until it binds).
4. Fold in Cranberries and Pistachios: Gently fold in the chopped dried cranberries and pistachios using a spatula or wooden spoon, ensuring they are evenly distributed throughout the dough.
5. Shape into Logs: Turn the dough out onto a sheet of parchment paper. Divide it in half and shape each half into a tight, smooth log (about 2 inches in diameter). Wrap the logs tightly in plastic wrap or parchment paper.
6. Chill the Dough: Chill the logs in the refrigerator for at least 2 hours (or up to 3 days). Crucial step: Chilling firms the butter so the cookies keep their neat round shape and don’t spread flat in the oven.
7. Slice and Bake: Preheat your oven to 350°F (175°C) and line two large baking sheets with parchment paper. Unwrap the chilled logs and use a sharp chef’s knife to slice them into even rounds about 1/4-inch thick. Place them on the baking sheets about 1 inch apart.
8. Bake: Bake for 12 to 15 minutes, or until the edges are just barely golden brown. The tops should remain pale.
9. Cool: Let the cookies cool on the baking sheet for 5 minutes (they are fragile when hot!), then transfer them to a wire rack to cool completely.

Pro-Tips for Success

• Slice with a Sharp Knife: If the pistachios or cranberries cause the edges to crumble slightly when cutting, just gently press any loose pieces back into place on the baking sheet before they go into the oven.
• Storage: These shortbread cookies keep remarkably well. Store them in an airtight container at room temperature for up to a week, or freeze the baked cookies (or unbaked logs) for up to 2 months.
