Preheat oven to 350°F (175°C). Grease a 9×13 inch baking dish or line it with parchment paper.

In a bowl, whisk together flour, sugar, and a pinch of salt.

In another bowl, cream the softened butter until smooth. Gradually add the dry mixture until combined. Fold in cranberries and white chocolate chips.

Spread mixture evenly in the baking dish and bake for 25-30 minutes until golden brown.

While cooling, beat cream cheese with powdered sugar until fluffy. Frost cooled bars and cut into squares.
