Description

This delightful Blackberry Coffee Cake features a tender, sour cream-based crumb topped with a buttery, golden brown sugar streusel. Bursting with fresh, jammy blackberries, this elegant treat is perfect for a cozy weekend breakfast or an afternoon tea gathering.


Ingredients

  • 1 1/2 cups all-purpose flour
  • 1/2 cup light brown sugar, packed
  • 1/2 cup granulated sugar
  • 1/2 cup unsalted butter, softened
  • 1/4 cup unsalted butter, cold and cubed
  • 1/2 cup sour cream
  • 2 large eggs
  • 1 tablespoon vegetable oil
  • 1 teaspoon pure vanilla extract
  • 1 teaspoon baking powder
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 1 1/2 cups fresh blackberries, halved
  • 1/2 cup powdered sugar
  • 1 tablespoon milk


Instructions

  1. Prepare the oven. Preheat the oven to 350°F and coat a nine-inch springform pan with non-stick baking spray.
  2. Assemble the streusel. Mix flour, brown sugar, salt, and cold cubed butter with a pastry blender until coarse crumbs form, then chill the mixture in the refrigerator.
  3. Combine dry ingredients. Whisk together the flour, sugars, baking powder, baking soda, and salt in a large mixing bowl until uniform.
  4. Mix wet ingredients. Incorporate room-temperature butter and oil into the dry mix, then blend in eggs, vanilla, and sour cream until smooth.
  5. Bake the cake. Spread batter into the pan, top with blackberries and chilled streusel, then bake for 50 to 55 minutes until a toothpick comes out clean.
  6. Glaze and serve. Cool the cake on a wire rack, then whisk together powdered sugar, vanilla, and milk to drizzle over the top before slicing.

Notes

  • Use room-temperature dairy and eggs to ensure the batter emulsifies properly for a lighter texture.
  • Pat blackberries dry with a paper towel before adding them to the batter to prevent excess moisture from sinking the fruit.
  • Keep your butter for the streusel ice-cold to create distinct, buttery crumbs rather than a melted sheet.
  • Measure your flour carefully using the spoon-and-level method to avoid a dense or dry crumb.
  • Wait for the cake to cool completely before applying the glaze to ensure the icing maintains its consistency.
