Preheat the oven to 350°F. Line a 9x13-inch baking pan with a parchment paper sling. Grease the parchment and pan with nonstick cooking spray.
Prep the blueberries: In a small bowl, toss the blueberries with 1 tablespoon flour. Set aside.
Make the batter: In a large mixing bowl, whisk together the remaining 2 cups flour, 1 ¼ cups granulated sugar, baking powder, baking soda, and salt. Add the eggs, milk, oil, and lemon zest to the flour mixture. Mix until just incorporated.
Top with blueberries and sugar: Pour the batter into the prepared baking pan. Arrange the blueberries on top and sprinkle evenly with the remaining 2 tablespoons of sugar.
Bake: Bake the cake until the edges are golden brown and a toothpick inserted into the center comes out clean, 35 to 37 minutes.
Cool, slice, and serve: Let the cake cool in the pan for 10 minutes. Use the parchment sling to transfer the cake to a wire rack to cool completely, about 1 hour. Slice and serve. Store leftovers in an airtight container at room temperature for up to 3 days. Love the recipe? Leave us stars and a comment below!

Can be frosted with lemon or cream cheese icing
Choose any blueberries: No fresh blueberries available? Use frozen berries instead. Just be sure to use them straight out of the freezer without letting them thaw
