Ingredients
- 1 1/2 cups all-purpose flour
- 1/2 cup white sugar
- 1/2 cup light brown sugar
- 1 teaspoon baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, softened
- 2 tablespoons vegetable oil
- 2 large eggs
- 1 teaspoon pure vanilla extract
- 1/2 cup sour cream
- 1 1/2 cups fresh blackberries, halved
- 1/2 cup all-purpose flour (for topping)
- 1/4 cup light brown sugar (for topping)
- 1/4 cup cold cubed unsalted butter (for topping)
- 1/2 cup powdered sugar (for glaze)
- 1 tablespoon milk (for glaze)
- 1/2 teaspoon vanilla extract (for glaze)
Instructions
- Prepare the oven. Set the oven to 350°F (177°C) and coat a nine-inch springform pan with non-stick baking spray.
- Assemble the streusel. Combine flour, brown sugar, salt, and cold butter in a bowl until crumbly, then refrigerate the mixture until needed.
- Mix dry ingredients. Sift the flour, white sugar, brown sugar, baking powder, baking soda, and salt into a large bowl and whisk thoroughly for one minute.
- Emulsify wet ingredients. Add room temperature butter and oil to the dry mix, then beat in the eggs, vanilla, and sour cream until a thick, uniform batter forms.
- Assemble and bake. Spread the batter into the prepared pan, top with halved blackberries and chilled streusel, and bake for 50 to 55 minutes until a tester comes out dry.
- Cool and glaze. Allow the cake to cool on a wire rack for fifteen minutes before removing the pan sides, then drizzle the whisked glaze over the completely cooled surface.
Notes
- Ensure all dairy and egg ingredients are at room temperature to create a stable batter emulsion.
- Pat blackberries completely dry after washing to prevent them from sinking into the cake during baking.
- Keep the streusel topping chilled in the freezer right up until the moment it goes into the oven for a crisper texture.
- Use a digital kitchen scale for ingredient measurements to avoid the inconsistencies of volume-based cup measurements.
- Wait until the cake is entirely cool before applying the glaze to ensure it sets properly and does not become absorbed.
