3/4 pound (3 sticks) unsalted butter, room temperature
1 cup sugar
1 teaspoon vanilla extract
3 1/2 cups all purpose flour
1/4 teaspoon kosher salt
3/4 cup chopped dried cranberries
1 cup roughly chopped pistachios
1 cup white chocolate chips

Cream together the butter and sugar until light and fluffy, about 3 minutes. Mix in the vanilla extract. In a separate bowl, whisk together the flour and salt. Add the flour & salt to the butter mixture. Mix on low speed until it just starts to come together. Add the cranberries, pistachios, and white chocolate a little at a time until it’s incorporated. Mix until the dough forms a ball. Roll into a log about 1 1/2 inch in diameter. Roll the log in parchment paper and chill it for at least 1 hour.
Preheat the oven to 350F and line a sheet pan with parchment paper. Slice the log into 1/4 inch slices. Place the slices on the sheet pan. They don’t spread much, so they can be pretty close together. Bake for 10-13 minutes, or until the edges are just starting to brown. Remove from the pan and cool on a wire rack.
