Ingredients

Scale
  • 2 ½ cups (312g) all-purpose flour, sifted
  • 2 tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt
  • ½ cup (113g) unsalted butter, softened
  • 1 cup (200g) granulated sugar
  • 2 large eggs, room temperature
  • 1 cup (240ml) sour cream, full-fat recommended
  • 2 tsp pure vanilla extract
  • 1 ½ cups (225g) fresh blueberries, washed and patted dry
  • ¾ cup (94g) all-purpose flour (for streusel)
  • ½ cup (100g) brown sugar, packed (preferably dark brown sugar)
  • 1 ½ tsp ground cinnamon
  • ¼ tsp ground nutmeg (optional)
  • 6 tbsp (85g) unsalted butter, cold and cut into small cubes (for streusel)

Instructions

  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with butter or non-stick spray.
  2. Make the streusel topping: In a medium bowl, combine ¾ cup flour, ½ cup brown sugar, 1 ½ tsp cinnamon, and ¼ tsp nutmeg. Add 6 tbsp cold, cubed butter and cut in with a pastry cutter or fork until mixture resembles coarse crumbs. Set aside.
  3. Prepare the cake batter: In a large bowl, whisk together 2 ½ cups flour, 2 tsp baking powder, ½ tsp baking soda, and ½ tsp salt.
  4. In a separate bowl, cream ½ cup softened butter with 1 cup granulated sugar until light and fluffy (3-4 minutes). Add eggs one at a time, beating well after each addition. Stir in sour cream and vanilla extract.
  5. Gradually add dry ingredients to wet mixture, mixing just until combined. Gently fold in blueberries with a spatula, being careful not to break them.
  6. Pour batter into prepared pan and smooth the top. Sprinkle streusel topping evenly over the batter.
  7. Bake for 40-45 minutes, or until a toothpick inserted in the center comes out clean or with a few moist crumbs and streusel is golden and crisp.
  8. Let the coffee cake cool in the pan on a wire rack for at least 20 minutes before slicing.

Notes

Use fresh blueberries for best results; toss berries in flour if using frozen to prevent sinking. Keep butter cold for streusel to maintain crumbly texture. Do not overmix batter to avoid tough cake. Streusel can be made a day ahead and refrigerated.
