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
- Prepare the oven. Preheat the oven to 350°F and coat a nine-inch springform pan with non-stick baking spray.
- 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.
- Combine dry ingredients. Whisk together the flour, sugars, baking powder, baking soda, and salt in a large mixing bowl until uniform.
- Mix wet ingredients. Incorporate room-temperature butter and oil into the dry mix, then blend in eggs, vanilla, and sour cream until smooth.
- 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.
- 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.
