Preheat oven to 350°F (175°C). Grease a 9×13-inch pan and line with parchment paper, leaving overhang.

Brown the butter in a saucepan over medium heat until golden and nutty. Transfer to a bowl and cool completely.

In a bowl, whisk flour, baking powder, and salt.

In a separate bowl, mix cooled browned butter and brown sugar until smooth. Stir in eggs, vanilla, and orange zest.

Fold dry ingredients into wet mixture just until combined. Add white chocolate and dried cranberries.

Spread batter evenly in prepared pan. Bake 18–22 minutes, until edges are golden and center is set.

Cool completely before frosting.

Beat cream cheese, powdered sugar, vanilla, orange juice, and zest until fluffy. Spread evenly over cooled bars.

Sprinkle chopped cranberries on top and drizzle with melted white chocolate.

Chill until set, then slice into triangles or bars and serve.
