• Preheat the oven to 350F.
• Beat the butter and brown sugar in a bowl until smooth.
• Add the eggs and vanilla. Beat for another minute or two until the mixture is smooth.
• Mix the flour, orange zest, baking powder, ground ginger, and salt in a separate bowl. Add those dry ingredients to the other bowl. Mix everything with a mixer or spatula.
• Add the chopped cranberries, white chocolate chips, and the orange juice.
• Mix everything thoroughly. The dough is quite thick, but very sticky and soft.
• Line a baking tray (about 8x10) with parchment paper and spread the dough in a thin layer (about 1/2 inch). Flatten with a spatula and bake for 20 minutes.
• When the bars are ready, remove them from the oven and let them cool slightly (15 minutes).

Frosting

• Beat the cream cheese with confectioner’s sugar, orange juice, orange zest, and vanilla. Beat for no more than 1 minute or until ingredients are combined.
• Spread the frosting onto the cooled bars.
• Sprinkle with chopped cranberries.
• Melt the white chocolate chips - it’s convenient to do this in the microwave in 30-second bursts (3-4 times).
• Drizzle melted chocolate over the bars. Let the chocolate harden for 10-15 minutes.
• Cut the bars into 3- to 4-inch squares, then cut each square on a diagonal before serving.
