Make Blueberry Sour Cream Coffee Cake: A Simple Method

Step 1: Preheat Your Oven
Begin by preheating your oven to 350°F (175°C). This ensures that your cake bakes evenly and thoroughly.
Step 2: Prepare the Baking Pan
Grease a 9×13-inch baking pan with butter or line it with parchment paper for easy removal.
Step 3: Cream Butter and Sugar
In a large mixing bowl, cream together 1 cup of softened butter and 2 cups of white sugar using an electric mixer. Beat until the mixture is light and fluffy, about 3-4 minutes.
Step 4: Add Eggs and Sour Cream
Add 2 large eggs, one at a time, mixing well after each addition. Then, stir in 1 cup of sour cream and 1 teaspoon of vanilla extract until well combined.
Step 5: Combine Dry Ingredients
In a separate bowl, whisk together 1 ¾ cups of all-purpose flour, 1 teaspoon of baking powder, and ¼ teaspoon of salt.
Step 6: Mix Dry Ingredients into Wet Ingredients
Gradually add the dry ingredients to the wet mixture, mixing just until combined. Be careful not to overmix.
Step 7: Fold in Blueberries
Gently fold in 1 ½ cups of fresh or frozen blueberries, ensuring they are evenly distributed throughout the batter.
Step 8: Prepare the Streusel Topping
In a small bowl, combine ½ cup of brown sugar, 1 teaspoon of ground cinnamon, and ½ cup of chopped pecans. Mix until well combined.
Step 9: Layer the Cake
Spread half of the cake batter into the prepared baking pan. Sprinkle half of the streusel topping over the batter. Then, add the remaining batter on top, followed by the rest of the streusel.
Step 10: Bake the Cake
Bake in the preheated oven for 45-50 minutes, or until a toothpick inserted into the center comes out clean.
Step 11: Cool and Dust
Allow the cake to cool in the pan for about 10 minutes before transferring it to a cooling rack. Once fully cooled, dust with confectioners’ sugar for a beautiful presentation.
Dietary Swaps & Alternatives

- For a dairy-free version, substitute the butter with coconut oil and the sour cream with a dairy-free yogurt.
- Use whole wheat flour instead of all-purpose flour for a healthier option.
- Replace the eggs with flaxseed meal or applesauce for a vegan cake.
- For a nut-free option, omit the pecans or substitute with sunflower seeds.
