In a large mixing bowl, cream the butter and the brown sugar until light and fluffy. Add in the egg, orange zest, and vanilla extract, and beat until incorporated.
10 tbsp butter, 1/2 cup brown sugar, 1 large egg, 1/2 tsp vanilla extract, 1/2 tbsp orange zest
Add in the flour, cinnamon, ginger, and salt and beat again just until combined. Add in the cranberries and the white chocolate chips and gently fold.
1 & 1/4 cup All purpose flour, 1/4 tsp salt, 1/4 tsp ground cinnamon, 1/8 tsp ground ginger, 1/4 cup dried cranberries, 4 oz white chocolate chips
Spread the blondie batter into the prepared baking pan with a rubber spatula, and bake for 2-22 minutes, until lightly browned. Don't worry if they are looking a bit soft in the center, they will continue baking as they cool. Cool the blondies completely before frosting.
