Ingredients Method Notes

Ingredients
  

  • 2 cups  all-purpose flour
  • 1 cup  granulated sugar
  • 2 teaspoons  baking powder
  • ½ teaspoon  baking soda
  • ½ teaspoon  salt
  • 2 large  eggs
  • ½ cup  unsalted butter, melted
  • 1 cup  sour cream
  • ¼ cup  milk
  • 2 teaspoons  vanilla extract
  • 1 ½ cups  blueberries 
  • 1 tablespoon  flour 
  • ½ cup  all-purpose flour
  • ⅓ cup  brown sugar
  • 3 tablespoons  granulated sugar
  • ½ teaspoon  cinnamon
  • 5 tablespoons  cold butter, cubed

Method
 

  1. Preheat your oven to 350°F (175°C). Grease and line an 8×8-inch or 9-inch square baking pan.
  2. In a small bowl, mix flour, brown sugar, granulated sugar, and cinnamon. Add the cold butter pieces and use your fingers or a fork to work them in until the mixture looks crumbly, like coarse sand.
  3. Set aside. The topping transforms the cake from “good” to “bakery-level.”
  4. In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt.
  5. In a separate bowl, combine the eggs, melted butter, sour cream, milk, and vanilla. Mix just until blended.
  6. Pour the wet mixture into the dry ingredients. Using a spatula, fold gently until you no longer see streaks of flour.
  7. Toss the blueberries with the tablespoon of flour. This small step keeps them from sinking to the bottom of the cake and helps the crumb stay even.
  8. Gently fold the blueberries into the batter.
  9. Spread the batter evenly into your prepared pan. Sprinkle the entire streusel mixture over the top.
  10. Bake for 45–55 minutes or until a toothpick inserted into the center comes out clean
  11. Let the cake cool in the pan for at least 20 minutes
  12. If using icing, whisk the powdered sugar, milk, and vanilla together, then drizzle lightly over the top.
