Ingredients You’ll Need

1 cup all-purpose flour: Spoon and leveled ensures accuracy. Essential for structure.
½ cup light brown sugar: Adds moisture and depth of flavor. You can substitute with coconut sugar or regular granulated sugar.
½ cup granulated sugar: Balances the sweetness; regular sugar works perfectly.
½ tsp ground cinnamon: This spice brings warmth. Swap for nutmeg for a different flavor twist.
Pinch of kosher salt: Elevates flavor; table salt will work in a pinch.
½ cup unsalted butter, melted: For richness; use ghee for a dairy-free option.
6 tbsp unsalted butter, room temp: Adds moisture; again, ghee can be an alternative.
¾ cup granulated sugar: Sweetness balance in the batter.
1 large egg, room temp: Provides structure and richness; flax egg works as a vegan alternative.
1 tsp vanilla extract: Adds a lovely warmth; vanilla bean paste can make flavors pop.
¾ cup sour cream, room temp: The star ingredient that gives the cake its moistness; plain Greek yogurt is a suitable substitute.
1 tsp baking powder: Leavens the cake; don’t skip this for that perfect rise.
½ tsp kosher salt: Balances the sweetness.
¼ tsp baking soda: Essential for the cake’s texture; it works hand in hand with the sour cream.
1½ cups all-purpose flour: Please remember to spoon and level for the right measurement.
2 cups fresh blueberries: Bursting with flavor; frozen blueberries can be used if fresh isn’t available (see notes).
Zest of 1 lemon: Brightens the flavor profile; the zest is more fragrant than the juice!
1 tbsp cornstarch: Coating the blueberries prevents sinking and keeps them juicy.
½ cup powdered sugar: For a drizzle that adds a sweet touch.
½ tbsp milk: Adds to the consistency; you can replace it with almond milk if desired.
½ tbsp lemon juice: Complements the glaze with a bit of acidity.

How to Make Blueberry Sour Cream Coffee Cake

Prepare the Crumble: In a medium bowl, use your hands to toss together 1 cup all-purpose flour, ½ cup light brown sugar, ½ cup granulated sugar, ½ tsp ground cinnamon, and a pinch of kosher salt. Stir in ½ cup melted unsalted butter until the mixture is evenly moistened and clumpy. Place this crumble in the refrigerator while you prepare the cake batter.
Preheat the Oven: Set your oven to 350°F and grease a 9″ springform pan, lining the bottom for easy release later.
Mix the Batter: In a large bowl, using an electric mixer (or mixing by hand), beat together 6 tbsp unsalted butter and ¾ cup granulated sugar until light and fluffy. Add in 1 large egg and 1 tsp vanilla extract; mix well. Now, stir in ¾ cup sour cream before adding in 1 tsp baking powder, ½ tsp kosher salt, and ¼ tsp baking soda. Ensure everything is well combined.
Prep the Blueberries: In a medium bowl, toss 2 cups fresh blueberries and the zest of 1 lemon together, adding 1 tbsp cornstarch until the blueberries are evenly coated.
Combine Everything: Gradually fold in 1½ cups all-purpose flour into your batter. Just before fully incorporated, add half of the blueberry mixture and fold gently. The batter should feel thick but homogenous.
Assemble the Cake: Spread the thick batter into the springform pan and top it with a layer of the remaining blueberries. Remove the crumble from the refrigerator and break it into fine crumbs with your hands, evenly layer it over the blueberries.
Bake: Place the cake in the oven and bake for 45-50 minutes or until the top turns golden brown and the center feels firm when nudged. A toothpick should come out clean when tested in the center.
Cool and Glaze: Once baked, allow the cake to cool at room temperature for about 20 minutes, then transfer it to the refrigerator and let it cool for about an hour. For the glaze, whisk together ½ cup powdered sugar, ½ tbsp milk, and ½ tbsp lemon juice, then drizzle over the slightly cooled cake.

Now, you can slice into this beauty and enjoy every delightful bite!

Storing & Reheating

After enjoying your blueberry sour cream coffee cake, store any leftovers at room temperature in an airtight container for up to 2 days. If you wish to keep it longer, move it to the refrigerator, where it should stay fresh for about a week. Freezing is also an option—simply wrap slices or the entire cake tightly with plastic wrap and foil to prevent freezer burn and enjoy it for up to 3 months. When you’re ready to taste it again, reheat in the oven at 350°F for about 10-15 minutes until warmed through, refreshing its texture.

Chef’s Helpful Tips

Always use room temperature ingredients for best mixing results; this helps the butter incorporate smoothly for fluffiness.
Be gentle while folding in the blueberries to prevent breaking them apart.
For a fluffier cake, ensure you properly measure your flour by spooning and leveling it rather than scooping.
If you notice the cake browning too quickly on top, you may loosely cover it with foil in the last 15 minutes of baking.
This coffee cake makes a fantastic make-ahead treat—prepare it a day early and let the flavors meld overnight for an even richer experience.

There’s something undeniably special about Blueberry Sour Cream Coffee Cake. It marries warmth and flavor, making it perfect for cozy mornings or lively gatherings. As you fold in those plump blueberries, remember to savor the moment. And don’t hesitate to experiment with ingredients and toppings! Enjoy every piece, and perhaps share a slice with a dear friend or loved one.

Recipe FAQs

Can I use frozen blueberries?

Absolutely! If you use frozen blueberries, keep them frozen until you’re ready to add them to the batter. This prevents them from bleeding into the cake and ensures they remain juicy.

Can I make this coffee cake gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free flour blend. Be sure to use one that is a 1:1 substitute for the best results.

How can I store the cake longer?

If you want to keep your cake tasty for longer, wrap it tightly in plastic wrap and aluminum foil and freeze it! It should last up to 3 months. Just thaw it in the refrigerator overnight before serving.

Why is my cake dense?

A dense coffee cake often results from overmixing the batter or using heavy flour measurements. Make sure to spoon and level flour for accuracy and mix just until combined for a light texture.
