Preparation
Step 1
For the cake:
Adjust oven rack to middle position and heat oven to 350°F. Grease and flour a 13 by 9-inch baking pan.
Whisk 2 cups flour, baking powder, and salt together in medium bowl. With electric mixer, beat softened butter and sugars on medium-high speed until fluffy, a couple of minutes. Add eggs, one at a time, beating until just incorporated and scraping down bowl as needed. Reduce speed to medium and beat in one-third of flour mixture until incorporated; followed by half of the milk. Beat in half of remaining flour mixture, then the remaining milk, and finally the remaining flour mixture. Toss blueberries with remaining one teaspoon flour. Using rubber spatula, gently fold in blueberries. Spread batter into prepared pan.
For the topping:
Scatter blueberries over top of batter. Stir sugar and cinnamon together in small bowl and sprinkle over batter. Bake until a toothpick inserted in he center of cake comes out clean, 45 to 50 minutes. Serve warm or at room temperature. (Cake can be stored in airtight container at room temperature up to 3 days.)
