- 1/2 teaspoon baking soda: Works with sour cream to produce a tender crumb.
- 1/4 teaspoon salt: Balances sweetness and enhances flavors.

How to Make Blueberry Sour Cream Coffee Cake Recipe
Step 1: Prepare and Preheat
Start by preheating your oven to 350°F (175°C). Grease a 9-inch square baking dish or springform pan well, ensuring your cake doesn’t stick and comes out beautifully after baking. This step is essential and sets the stage for even cooking and easy removal.
Step 2: Cream Butter and Sugar
In a large bowl, cream together the softened butter and granulated sugar until the mixture becomes light and fluffy. This process traps air in the batter, which helps make the cake tender and rise nicely. Once creamed, beat in the eggs one at a time, making sure each is fully incorporated before adding the next.
Step 3: Add Vanilla and Sour Cream
Mix in the vanilla extract to lift the flavors and then add the sour cream for that signature moistness and subtle tang that defines this coffee cake. The sour cream does double duty—it tenderizes the crumb while lending a gentle richness.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This ensures that your leavening agents and salt are evenly distributed in the batter for consistent texture and flavor.
Step 5: Mix Wet and Dry Ingredients
Gradually add the dry ingredients to the wet mixture, stirring just until combined. Overmixing can make the cake dense, so gently fold the ingredients to keep the batter light and airy.
Step 6: Fold in Blueberries and Pour Batter
Carefully fold in your fresh or frozen blueberries without thawing to avoid excess moisture in the batter. They will provide juicy bursts of flavor throughout the cake. Spread the batter evenly in the prepared pan to ensure even baking.
Step 7: Make and Sprinkle Streusel Topping
Mix together granulated sugar, brown sugar, cinnamon, salt, and flour in a bowl. Then stir in the melted butter until the mixture forms crumbly clusters. Sprinkle this streusel generously over the blueberry batter. This crunchy topping adds wonderful texture contrast to the soft cake beneath.
Step 8: Bake
Bake your coffee cake for 40 to 45 minutes. Use a toothpick to test doneness—it should come out clean or with just a few moist crumbs attached. Once done, let the cake cool in the pan for about 10 minutes before slicing. This rest time helps the cake set perfectly for neat slices.
How to Serve Blueberry Sour Cream Coffee Cake Recipe

Garnishes
Serving your Blueberry Sour Cream Coffee Cake Recipe with a dusting of powdered sugar or a simple glaze can elevate its appearance and add an extra dash of sweetness. Fresh blueberries or a sprig of mint on top can also make it look irresistible and fresh.
Side Dishes

Creative Ways to Present
For a special occasion, serve slices with whipped cream or a scoop of vanilla ice cream for a dessert twist. You could also cut the cake into smaller squares and serve it on a platter as bite-sized treats at a gathering or party.
Make Ahead and Storage
Storing Leftovers
Once cooled completely, cover your Blueberry Sour Cream Coffee Cake Recipe tightly with plastic wrap or store it in an airtight container. It will keep fresh at room temperature for up to 2 days, but refrigeration will extend its life to about 5 days, keeping it moist and delicious.
Freezing
You can freeze this coffee cake if you want to enjoy it later. Wrap it well in plastic wrap and aluminum foil or store in a freezer-safe container. It freezes beautifully for up to 2 months. Thaw overnight in the fridge before serving for best texture.
Reheating
To enjoy the coffee cake warm, reheat slices in the microwave for about 15-20 seconds or in an oven at 300°F (150°C) for 10-15 minutes. This brings back the fresh-baked softness and enhances the flavors.
FAQs
Can I use frozen blueberries in this Blueberry Sour Cream Coffee Cake Recipe?
Yes, you can use frozen blueberries without thawing them. Adding them frozen helps prevent the batter from becoming too watery and preserves little bursts of blueberry flavor throughout the cake.
What if I don’t have sour cream? Can I substitute it?
You can substitute sour cream with Greek yogurt or buttermilk in equal amounts. These alternatives will maintain the cake’s moist texture and slight tang, though sour cream usually provides the richest flavor.
How do I know when the coffee cake is done baking?
Insert a toothpick into the center of the cake after about 40 minutes. If it comes out clean or with just a few crumbs sticking to it, the cake is fully baked. If batter sticks, give it a few more minutes and test again.
Can I make this cake gluten-free?
Yes! Replace the all-purpose flour with a gluten-free baking blend that measures one-to-one. The texture might vary slightly, but it will still be moist and flavorful.
Is this Blueberry Sour Cream Coffee Cake Recipe suitable for breakfast?
Absolutely! This coffee cake is a fantastic breakfast or brunch option. The combination of blueberries, cinnamon streusel, and moist cake makes it a comforting morning treat any day of the week.
