Step-by-Step blueberry sour cream coffee cake

1. Preheat the oven to 350°F (175°C). Greasing and flouring a 9-inch round cake pan will ensure your cake slides out easily after it bakes to perfection.
2. Cream together 1/2 cup of softened unsalted butter and 1 cup of granulated sugar in a mixing bowl until the mixture is light and fluffy, about 3-5 minutes for that airy texture.
3. Add the eggs, two large ones, one at a time. Mix well after each addition, then stir in 1 teaspoon of vanilla extract and 1 cup of sour cream for a creamy base.
4. Whisk together 2 cups of all-purpose flour, 1 teaspoon of baking powder, 1/2 teaspoon of baking soda, and 1/4 teaspoon of salt in another bowl. This dry mixture will give your cake structure.
5. Gradually combine the dry ingredients with the wet mixture, stirring until just combined. Gently fold in 2 cups of fresh blueberries (or thawed frozen ones), ensuring they’re evenly distributed without overmixing.
For the Streusel Topping:
6. Mix together 1/2 cup of all-purpose flour, 1/2 cup of packed brown sugar, and 1 teaspoon of cinnamon in a small bowl. Cut in 1/4 cup of cold cubed butter until the mixture resembles coarse crumbs—this adds a delightful crunch!
Bake the Cake:
7. Pour the batter into your prepared cake pan and evenly sprinkle the streusel topping over the surface for a sweet finish.
8. Bake in your preheated oven for 35-40 minutes. Check with a toothpick inserted into the center; it should come out clean when your blueberry sour cream coffee cake is ready!
9. Cool the cake in the pan for about 10 minutes before transferring it to a wire rack to cool completely—this will help set those delicious flavors.
Optional: Serve warm with a dusting of powdered sugar for an extra touch!

Tips for the Best blueberry sour cream coffee cake
- Room Temperature Ingredients: Use room temperature eggs and sour cream for a smoother batter. This helps create that moist texture in your blueberry sour cream coffee cake.
- Don’t Overmix: When combining the wet and dry ingredients, mix until just combined. Overmixing can lead to a dense cake, so be gentle!
- Fresh vs. Frozen Blueberries: If using frozen blueberries, thaw and drain them first to avoid excess moisture which can affect the cake’s consistency.
- Streusel Consistency: Ensure your streusel topping has a crumbly texture. Cutting in the cold butter properly creates those delightful chunks of flavor.
- Oven Thermometer Check: Ovens can often be inaccurate; using an oven thermometer ensures your blueberry sour cream coffee cake bakes perfectly at 350°F without burning or undercooking.
- Cooling Time Matters: Allow the cake to cool in the pan for 10 minutes before transferring to a wire rack. This prevents it from breaking apart while still warm.

Room Temperature: Keep your blueberry sour cream coffee cake covered in an airtight container for up to 2 days to maintain its freshness.

Feel free to get creative and tailor this delightful recipe to suit your taste buds!
