Preheat your oven to 350°F (175°C) and prepare a 9x13 inch pan with nonstick spray and parchment paper.

Melt ½ cup of unsalted butter over medium heat until golden brown, then cool slightly.

In a bowl, whisk together 1 ½ cups flour, 1 teaspoon baking powder, and ½ teaspoon salt. Set aside.

In a large bowl, combine melted butter and 1 cup light brown sugar until smooth. Add 2 eggs, 1 teaspoon vanilla, and orange zest.

Fold the dry ingredients into the wet mixture, then add 1 cup dried cranberries and ½ cup white chocolate chips.

Spread batter into the prepared pan and bake for 18-22 minutes. Cool on a wire rack.

For frosting, beat together 8 oz cream cheese, 2 cups confectioners' sugar, 1 teaspoon vanilla, and 2 tablespoons orange juice until smooth.

Spread frosting over cooled bars, top with chopped cranberries, and drizzle with ¼ cup melted white chocolate. Chill until set.

Slice into squares and serve.
