Preheat oven to 350 degrees. Line an 8 x 8-inch cake pan with parchment paper and allow the paper to slightly hang over the edges of the pan. Sift the dry ingredients into a large mixing bowl until they are combined and there are no lumps. Stir the wet ingredients into the dry ingredients until fully combined and a thick, crumbly batter forms.
Scrape down the sides of the bowl and press the batter into the center of the bowl. Gradually fold in the white chips and chopped strawberries until they are evenly distributed throughout the batter. Press the batter firmly and evenly throughout the prepared cake pan.
Bake at 350 degrees for 25 to 30 minutes or until golden and a tester come out clean. Once baked, remove the blondies from the oven and allow them to cool in the pan at least 30 minutes until firm. Once firm, grasp the overhanging paper and transfer the blondie slab to a wire rack. Allow to cool completely before applying frosting or slicing into desired pieces.
