Instructions
1. Preheat the Oven:
- Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish or line it with parchment paper for easy removal.
2. Make the Cake Batter:
- In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
- Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract and sour cream until well combined.
- In a separate bowl, whisk together the flour, baking powder, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, mixing until just combined.
- Gently fold in the blueberries, being careful not to overmix to avoid crushing the berries.
3. Prepare the Streusel Topping:
- In a small bowl, combine the flour, brown sugar, and cinnamon. Pour in the melted butter and mix until crumbly.
4. Assemble the Cake:
- Pour half of the cake batter into the prepared baking dish and spread it evenly. Sprinkle half of the streusel topping over the batter. Add the remaining batter on top and finish with the remaining streusel.
5. Bake the Cake:
- Bake in the preheated oven for 35-40 minutes, or until a toothpick inserted in the center comes out clean. The top should be golden brown and the cake should spring back when lightly pressed.
6. Prepare the Glaze (Optional):
- While the cake cools, whisk together the powdered sugar, milk (or cream), and vanilla extract in a small bowl until smooth. Adjust the consistency by adding more milk for a thinner glaze or more powdered sugar for a thicker glaze.
7. Serve:
- Once the cake has cooled for about 10-15 minutes, drizzle the glaze over the top if desired. Slice into squares and serve warm or at room temperature. This coffee cake is perfect on its own or paired with a cup of coffee or tea.
Tips for Success
- Use Fresh or Frozen Blueberries: If using frozen blueberries, do not thaw them before adding them to the batter. This will help prevent the batter from turning blue.
- Room Temperature Ingredients: Ensure that your eggs and sour cream are at room temperature for a better mix and texture.
- Check for Doneness: Oven temperatures can vary, so be sure to check the cake a few minutes before the suggested baking time.
Variations to Try
- Mix of Berries: Feel free to substitute or add other berries such as raspberries, strawberries, or blackberries for a mixed berry coffee cake.
- Lemon Zest: For a citrusy twist, add the zest of one lemon to the batter or glaze for a refreshing flavor.
- Nuts: Add chopped walnuts or pecans to the streusel topping for added crunch and flavor.
