Preheat the oven to 350°F (175°C). Line a 9x13-inch baking pan with parchment paper, making sure to leave an overhang on two sides for easy removal later.
In a stand mixer fitted with a paddle attachment, cream together the cold butter, sugar, and brown sugar until the mixture is light and fluffy, which should take about 2 minutes. This step is crucial for creating a good texture.
Add the eggs one at a time, beating well after each addition. Then mix in the vanilla extract and fresh orange zest for a delightful aroma.
In a separate bowl, combine the flour, baking powder, and 1/2 teaspoon of salt. Gradually incorporate this dry mixture into the wet ingredients, mixing until just combined. Be careful not to overmix!
Stir in the white chocolate chips and dried cranberries gently. Transfer the dough to the prepared pan, pressing it into an even layer.
Bake the bars for about 25 minutes, or until they are fully set and golden brown. Once baked, let them cool completely in the pan.
For the topping, beat the cream cheese and butter in a stand mixer until smooth and creamy. Gradually add in the powdered sugar and 1/2 teaspoon of vanilla extract, mixing until well combined.
Once the bars have cooled, spread the cream cheese frosting evenly over the top. Sprinkle additional dried cranberries on top for a pop of color and sweetness.
Melt the remaining white chocolate chips in the microwave until smooth and drizzle it over the bars. Allow the chocolate to set before slicing.
Slice the bars into squares and serve. Enjoy your delicious Cranberry White Chocolate Bars!
