Ingredients You’ll Need

1 cup all-purpose flour: The base of our cake, helping to create that tender crumb.
⅔ cup dark brown sugar: Adds a rich molasses flavor; light brown sugar can be substituted.
½ cup granulated sugar: Sweetens the cake without overpowering the flavors.
1 teaspoon ground cinnamon: Infuses warm spices for that comforting aroma.
⅛ teaspoon salt: Enhances the sweetness and balances flavors.
½ cup butter (melted): Provides richness; for a lighter alternative, consider using coconut oil.
1 ½ cups all-purpose flour: Helps create a sturdy cake structure.
1 teaspoon baking powder: Leavens the cake, making it fluffy.
½ teaspoon salt: Another balance of flavors for the cake.
¼ teaspoon baking soda: Works with the sour cream for a tender crumb.
6 tablespoons butter (room temperature): Essential for creaming with the sugars, contributing to the cake’s airy texture.
¾ cup granulated sugar: Sweetness in the batter itself.
1 large egg (room temperature): Binds the ingredients while adding moisture.
¾ cup sour cream (room temperature): Adds moisture and a tangy flavor; Greek yogurt could be a substitute.
½ teaspoon vanilla extract: Provides a lovely flavor backdrop.
1 ½ cups blueberries (fresh or frozen): The star ingredient! Fabulously sweet and juicy.
1 tablespoon cornstarch: Coats the blueberries to prevent them from sinking in the batter.
Zest of 1 lemon: Adds brightness to the cake and complements the blueberries.
½ cup powdered sugar: For a sweet glaze.
1 tablespoon lemon juice: Lightens the glaze and adds a zesty finish.

How to Make Blueberry Sour Cream Coffee Cake

Preheat Your Oven: Start by preheating your oven to 350°F (180°C). Butter and line the bottom of a 9″ (23 cm) springform pan with parchment paper for easy release after baking.
Make the Streusel: In a medium bowl, combine 1 cup flour, ⅔ cup dark brown sugar, ½ cup granulated sugar, 1 teaspoon cinnamon, and ⅛ teaspoon salt. Mix in the melted butter until it clumps together. Refrigerate until you need it.
Prepare the Dry Ingredients: Whisk together the remaining 1 ½ cups of all-purpose flour, 1 teaspoon baking powder, ½ teaspoon salt, and ¼ teaspoon baking soda in a separate bowl. This ensures even distribution of the leavening agents.
Cream Butter and Sugar: In the bowl of a stand mixer fitted with a paddle attachment (or using a handheld electric mixer), cream 6 tablespoons of room temperature butter with ¾ cup granulated sugar on medium-high speed until the mixture becomes pale and fluffy, around 3 minutes.
Add Egg and Sour Cream: Lower the mixer speed to medium, then mix in 1 large egg, ¾ cup sour cream, and ½ teaspoon vanilla extract just until combined.
Incorporate Dry Ingredients: Gradually add the flour mixture in two additions, mixing on low until just combined. Be careful not to over-mix, as this can toughen the cake.
Assemble the Cake: Spread the batter evenly into the prepared pan. In a medium bowl, toss the blueberries with 1 tablespoon cornstarch and lemon zest, then sprinkle this mixture over the batter.
Top with Streusel: Generously crumble the reserved streusel topping over the blueberries for that delightful crunch.
Bake: Place the pan on a rimmed baking sheet and bake for 45-50 minutes. Keep an eye on it, and check for doneness by inserting a toothpick in the center — it should come out clean.
Cool the Cake: Once baked, allow the cake to cool for about 1 hour at room temperature. When cool, release the sides of the springform pan and transfer the cake to a serving plate.
Glaze the Cake: In a small bowl, whisk together ½ cup powdered sugar and 1 tablespoon lemon juice. Drizzle this sweet glaze over the top of the cake and let it set for about 10 minutes before serving.
Serve & Enjoy: Slice, serve, and enjoy the delicious blend of flavors!

Storing & Reheating

Store any leftovers in a covered container at room temperature for up to 3 days. If you wish to keep it longer, refrigeration will allow it to stay fresh for up to one week. You can also freeze individual slices in an airtight container for up to 3 months. To reheat, place a slice in the microwave for about 15–20 seconds; however, note that while flavor will remain, the texture may slightly change. A light dusting of powdered sugar before serving can refresh its appearance.

Chef’s Helpful Tips

Avoid over-mixing the batter once the dry ingredients are added to ensure a tender cake.
Ensure your egg and sour cream are at room temperature for optimal mixing; this creates a smoother batter.
If your blueberries are frozen, don’t thaw them; just toss them directly into the batter to prevent them from bleeding color too much.
Experiment with your favorite berries or a mix of berries for a unique twist!
Lightly dust the blueberries in flour before adding to the batter for them to suspend more evenly.
You can prepare the streusel topping a day in advance and keep it refrigerated.

This Blueberry Sour Cream Coffee Cake is bound to become a favorite in your kitchen. Its deliciously balanced flavors and tender crumb make it a recipe you’ll want to return to time and again. Don’t be shy about experimenting with different fruits or flavorings to make it your own! I can’t wait for you to share this delicious creation with your loved ones, relishing each delightful bite together.

Recipe FAQs

Can I use frozen blueberries in this recipe?

Absolutely! Frozen blueberries can be used without thawing. This helps maintain their shape and prevents the batter from turning purple. Just toss them in with the cornstarch before adding to the batter.

How do I know when the cake is done baking?

The cake will be golden brown on top, and a toothpick inserted into the center should come out clean or with a few moist crumbs. The edges should also start to pull away from the pan.

How can I make this recipe gluten-free?

You can substitute the all-purpose flour with a gluten-free baking blend. Just ensure that the blend includes xanthan gum, as it helps mimic the texture of regular flour.

Can I make the streusel topping ahead?

Absolutely! You can prepare the streusel topping a day ahead of time. Just store it in an airtight container in the refrigerator until you’re ready to use it.
