In a small bowl, rub the granulated sugar and lemon zest together, using your fingers, until fragrant. Using a mixer, beat together butter and sugars until creamy. Add in lemon pudding mix, eggs, and vanilla extract. In a medium bowl, whisk together the flour, baking soda, and salt. Add the dry ingredients to the wet ingredients and mix until just combined. Stir in the dried blueberries and white chocolate chips.
