Why This Recipe Stands Out

Before diving into the details, here’s why this Blueberry Sour Cream Coffee Cake deserves a spot on your table:

1. Juicy Blueberries : Fresh or frozen blueberries add bursts of sweetness and color.
2. Creamy Texture : Sour cream keeps the cake moist and tender while adding a subtle tang.
3. Easy to Make : Requires no special tools or techniques—just simple ingredients and minimal prep work.
4. Customizable : Swap out blueberries for other fruits or adjust spices to suit your taste.

Now let’s explore the ingredients and instructions in detail.

Ingredients You’ll Need

For the Cake:

• 1 ½ cups all-purpose flour
  (Provides structure while keeping the cake light.)
• 1 cup granulated sugar
  (Sweetens the cake without overpowering the berries.)
• 1 teaspoon baking powder
  (Helps the cake rise evenly during baking.)
• ½ teaspoon baking soda
  (Enhances leavening and reacts with the sour cream for extra fluffiness.)
• ¼ teaspoon salt
  (Balances sweetness and enhances other flavors.)
• ½ cup sour cream
  (Keeps the cake moist and adds tanginess.)
• ½ cup unsalted butter , melted
  (Richens the batter and ensures tenderness.)
• 1 large egg
  (Acts as a binder and contributes moisture.)
• 1 teaspoon vanilla extract
  (Enhances the overall aroma and taste.)
• 1 cup fresh or frozen blueberries
  (For fruity bursts of flavor.)

For the Streusel Topping:

• ½ cup all-purpose flour
  (Forms the base of the crunchy topping.)
• ¼ cup brown sugar
  (Adds sweetness and helps create a caramelized texture.)
• 2 tablespoons unsalted butter , softened
  (Binds the streusel together and adds richness.)
• 1 teaspoon ground cinnamon
  (Brings warmth and depth to the topping.)

Step-by-Step Instructions

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C) . Grease and flour a 9×9-inch baking pan or line it with parchment paper for easy removal.

Step 2: Prepare the Streusel Topping

1. In a small mixing bowl, combine the flour , brown sugar , and cinnamon .
2. Use a fork or pastry cutter to mix in the softened butter until the mixture resembles coarse crumbs. Set aside.

Step 3: Mix the Cake Batter

1. In a large mixing bowl, whisk together the all-purpose flour , granulated sugar , baking powder , baking soda , and salt .
2. Stir in the sour cream , melted butter , egg , and vanilla extract until smooth and well combined.
3. Gently fold in the blueberries , ensuring they’re evenly distributed throughout the batter but not crushed.

Step 4: Assemble the Cake

1. Pour half of the cake batter into the prepared pan and spread it evenly.
2. Sprinkle about ⅔ of the streusel topping over the batter layer.
3. Add the remaining batter on top, spreading gently to avoid disturbing the streusel.
4. Finish by sprinkling the rest of the streusel evenly across the surface.

Step 5: Bake Until Golden

Bake the cake in the preheated oven for 40–45 minutes , or until a toothpick inserted into the center comes out clean. If the top begins browning too quickly, cover loosely with aluminum foil.

Step 6: Cool and Serve

Let the cake cool in the pan for 15–20 minutes before slicing. Dust with powdered sugar if desired and serve warm or at room temperature.
