Equipment

  • 9x13 inch baking pan A glass or dark-colored pan is recommended.
  • Mixing bowls At least two, one large and one medium.

Ingredients
  

Batter

  • 2 cups all-purpose flour
  • 1 cup granulated sugar
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 1 tsp salt
  • 1 cup buttermilk
  • 1 tsp vanilla extract

Topping

  • 1 cup all-purpose flour
  • 1 cup brown sugar packed
  • 1 cup rolled oats
  • 1 cup chopped walnuts optional
  • 1 cup cold butter cut into small pieces
  • 3 cups fresh blueberries

Instructions
 

  • Preheat oven to 375°F (190°C). Grease and flour a 9x13 inch baking pan.
  • In a large bowl, whisk together the flour, sugar, baking powder, baking soda, and salt from the "Batter" group (ing_1, ing_2, ing_3, ing_4, ing_5).
  • Add the buttermilk (ing_6) and vanilla extract (ing_7) to the dry ingredients; mix until just combined. Gently fold in the blueberries (ing_13).
  • In a medium bowl, combine the flour (ing_8), brown sugar (ing_9), oats (ing_10), and walnuts (ing_11) from the "Topping" group. Cut in the cold butter (ing_12) using a pastry blender or your fingers until the mixture resembles coarse crumbs.
  • Pour the batter into the prepared pan. Sprinkle the topping evenly over the batter.
  • Bake for 45-50 minutes, or until a wooden skewer inserted into the center comes out clean.
  • Let cool in the pan for 10 minutes before serving.

Notes

For a richer flavor, use brown sugar in the batter as well. You can also substitute other berries for the blueberries.
