What Kind of Blueberries Should I Use for Blueberry Coffee Cake?

You can use either fresh or frozen blueberries in this recipe. Fresh berries are ideal for a burst of summer flavor, but frozen work beautifully too—just add them straight from the freezer (don’t thaw), and toss lightly with a spoonful of flour to prevent sinking. Wild blueberries will give you a more intense color and taste, while regular ones keep things sweet and classic.

Ingredients for the Blueberry Coffee Cake

Every ingredient in this recipe plays an essential role. The butter creates a rich, tender crumb, while sour cream adds a subtle tang and ensures the cake stays moist.

The streusel topping brings that irresistible crunch and extra cinnamon warmth—don’t skip it!

How To Make the Blueberry Coffee Cake

Step 1: Make the Streusel Topping

In a small bowl, combine ½ cup all-purpose flour, ⅓ cup brown sugar, ¼ cup granulated sugar, 1 teaspoon cinnamon, and a pinch of salt. Add ¼ cup (½ stick) cold unsalted butter, cut into cubes. Use your fingers or a pastry cutter to blend until the mixture resembles coarse crumbs. Set aside.

Step 2: Prepare the Cake Batter

Preheat your oven to 350°F (175°C). Grease and flour a 9-inch square baking pan. In a medium bowl, whisk together 2 cups all-purpose flour, 2 teaspoons baking powder, ½ teaspoon baking soda, and ¼ teaspoon salt. In a large bowl, beat ½ cup (1 stick) unsalted butter and ¾ cup granulated sugar until light and fluffy. Add 2 large eggs, one at a time, then stir in 1 teaspoon vanilla extract and 1 teaspoon finely grated lemon zest. Mix in 1 cup sour cream.

Step 3: Combine the Batter and Blueberries

Gently fold the dry ingredients into the wet until just combined (do not overmix). Toss 1½ cups fresh or frozen blueberries with 1 tablespoon flour, then fold them into the batter.

Step 4: Layer and Bake

Spread half the batter evenly into the prepared pan. Sprinkle half the streusel over the batter, then add the remaining batter and top with the rest of the streusel. Bake for 45–50 minutes, or until a toothpick inserted in the center comes out clean. Let cool before slicing.
