Copycat Starbucks Cranberry Bliss Bars

Preheat oven to 350° with a rack in center of oven. Line a 9”-x-13” baking pan with parchment, leaving a 2” overhang on 2 sides. Grease parchment with cooking spray. In a medium bowl, whisk flour, baking powder, ginger, and salt.  In a large bowl, whisk melted butter and sugar until combined. Add eggs and vanilla, and mix until incorporated. Add dry ingredients and mix until just combined. Stir in dried cranberries and white chocolate chips.  Pour batter into prepared pan and smooth top. Bake until golden on the edges and a toothpick inserted in the middle comes out clean, 23 to 25 minutes. Let cool completely.  Make frosting: In a large bowl using a hand mixer, beat cream cheese and powdered sugar until smooth. Add zest and vanilla, and beat to combine.  Using an offset spatula, frost cooled blondies. Top with dried cranberries, then drizzle with melted chocolate. Refrigerate until chocolate is hardened, about 20 minutes. Cut blondies into 24 triangles.
