Preheat oven to 400°F. Grease and flour a 9-inch square baking pan and set aside.
In a large bowl, whisk together 1 cup flour, cornmeal, sugar, salt and baking powder. Make a well in the center and set aside.
In a separate bowl, whisk together the oil, egg, and buttermilk. Pour into the dry ingredients and stir until just incorporated.
In a small bowl, toss together the blueberries with the remaining 2 tablespoons flour. Add to the batter and fold carefully with a rubber spatula. Transfer to the prepared baking pan and spread out evenly.
Bake until golden brown and a toothpick, inserted in the center, comes out clean, for 20 to 25 minutes. Remove from the oven and allow to cool for 10 minutes in the pan before slicing and serving with butter and honey. Enjoy!
