Blueberry Coffee Cake is the ultimate tender, buttery, and bursting-with-blueberries treat — a soft, moist coffee cake studded with juicy blueberries and topped with a generous layer of cinnamon-spiced streusel. This recipe is a celebration of simple, comforting baking, where a rich, buttery cake batter meets a crunchy, brown sugar streusel for a breakfast or snack cake that’s impossible to resist. The magic begins with a simple streusel topping made from flour, brown sugar, cinnamon, and chilled butter, cut together until crumbly. While the streusel chills, a tender cake batter comes together with creamed butter and sugar, eggs, vanilla, and a mix of flour and milk. Fresh or frozen blueberries are gently folded in, adding bursts of sweet, juicy flavor throughout the cake.
The brilliance of this coffee cake lies in its texture and flavor — the soft, buttery crumb, the juicy blueberries, and the crunchy, cinnamon-sweet streusel on top all come together in perfect harmony. It’s the perfect treat for a weekend brunch, a holiday breakfast, or an afternoon snack with a cup of coffee. Serve it warm or at room temperature, and watch it disappear.

INGREDIENTS
For the Streusel Topping:
- ⅔ cup all-purpose flour
- ⅔ cup brown sugar
- 1 teaspoon ground cinnamon
- ½ cup well-chilled unsalted butter, cut in small cubes
For the Blueberry Coffee Cake:
- 2 cups all-purpose flour
- 2 teaspoons baking powder
- ½ teaspoon salt
- ½ cup unsalted butter, softened
- ¾ cup granulated sugar
- 2 large eggs, room temperature
- 1½ teaspoons vanilla extract
- ½ cup milk, warmed to room temperature
- 2 cups fresh or frozen blueberries
INSTRUCTIONS
Step 1: Preheat Oven and Prepare Pan
Preheat your oven to 350°F (175°C). Grease a 7×11 or 9×9-inch baking dish with butter or shortening.
Step 2: Make the Streusel Topping
In a medium bowl, combine the flour, brown sugar, cinnamon, and butter for the streusel. Using a pastry knife, cut in the butter until it is crumbly. Cover and refrigerate while you mix the blueberry cake.
Step 3: Mix the Dry Ingredients
Whisk the flour, baking powder, and salt in a medium bowl.
Step 4: Make the Cake Batter
In a large bowl, cream the butter and sugar until light and fluffy. Add the eggs one at a time and the vanilla extract and beat on low just until combined. Scrape down the bowl and beaters when needed.
Step 5: Combine Wet and Dry
Stir in the flour mixture and the milk in 3 increments, alternating between the two. Mix just until combined.
Step 6: Add Blueberries and Assemble
Gently stir in the blueberries. The batter will be thick. Spoon it into the prepared baking dish and use an offset spatula to level the batter. Sprinkle evenly with the streusel.
Step 7: Bake
Bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean.
Step 8: Cool and Serve
Cool for 30 minutes before slicing.
TIPS
- Mix just until combined — overmixing can result in a dense or gummy texture.
- Let it cool — cooling for 30 minutes makes for nice, clean slices.
- Use frozen blueberries — no need to thaw; they work beautifully in this cake.
- Store properly — wrap well or place in an airtight container at room temperature for up to 3 days.
- Add a glaze — a simple powdered sugar glaze takes this coffee cake over the top.
STORAGE OPTIONS
Room Temperature: Store in an airtight container at room temperature for up to 3 days. If you live in a hot or humid climate, cover and store in the refrigerator.
Freezer: This coffee cake freezes well for up to 2 months. Wrap tightly in plastic wrap and foil. Thaw at room temperature before serving.
