Preheat oven to 350 degrees.
Brush a 9-inch baking pan with the EVOO and line with parchment paper.
In a medium/large bowl, whisk together 1/2 cup of EVOO, buttermilk, eggs, vanilla extract and 1 cup sugar.
In a separate medium bowl, whisk 1 1/2 cups flour, baking powder, baking soda and salt to combine. Whisk wet ingredients into dry until just combined.
Toss berries on a plate with remaining 1 tablespoon flour, then fold into the batter and transfer to your baking dish. Sprinkle and evenly coat the remaining 2 tablespoons sugar on top.
Bake until golden, 50 to 55 minutes. Insert a toothpick into the center, if it comes out clean, it’s done. Let it cool slightly before serving.
