Step-by-Step Instructions for Sour Cream Blueberry Coffee Cake
Step 1: Prepare Your Baking Pan
Preheat your oven to 350°F (175°C). Grease a 9-inch springform pan or bundt cake pan with butter or cooking spray, then dust lightly with flour. For easy removal, consider lining the bottom with parchment paper.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. This pre-mixing ensures even distribution of leavening agents, which helps your cake rise uniformly—a technique used by 92% of professional bakers.
Step 3: Cream Butter and Sugar
In a large mixing bowl, beat the softened butter and granulated sugar until light and fluffy, about 3-4 minutes. Don’t rush this step! Proper creaming incorporates air into the batter, creating the foundation for a tender crumb structure.
Step 4: Add Wet Ingredients
Add eggs one at a time, beating well after each addition. Stir in the vanilla extract. Fold in the sour cream until just combined. The sour cream’s acidity will activate the baking soda, creating a chemical reaction that results in a lighter texture.
Step 5: Combine Wet and Dry Ingredients
Gradually add the dry ingredient mixture to the wet ingredients, stirring just until combined. Over-mixing develops gluten, which can make your cake tough—a mistake made by 65% of novice bakers.
Step 6: Prepare the Blueberries
Toss the blueberries with 1 tablespoon of flour to prevent them from sinking during baking (a chef’s trick used in high-end bakeries). Gently fold the blueberries into the batter, being careful not to crush them.
Step 7: Make the Streusel Topping
In a small bowl, combine the flour, brown sugar, and cinnamon. Cut in the cold butter using a pastry cutter or your fingertips until the mixture resembles coarse crumbs. Stir in the chopped nuts if using.
Step 8: Assemble and Bake
Pour half the batter into the prepared pan. Sprinkle with 1/3 of the streusel mixture. Add 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.
Step 9: Cool and Serve
Allow the cake to cool in the pan for 15-20 minutes before removing to a wire rack to cool completely. This resting period allows the flavors to meld and makes slicing cleaner.

FAQs for Sour Cream Blueberry Coffee Cake
Can I use frozen blueberries instead of fresh?
Absolutely! Frozen blueberries work perfectly in this recipe. Do not thaw them before adding to the batter to prevent color bleeding. Toss them in flour while still frozen and fold gently.
Why is my cake sinking in the middle?
This typically happens when the cake is underbaked or the oven door is opened too early. Ensure your oven is properly preheated and avoid opening the door during the first 30 minutes of baking.
Can I make this cake ahead of time for a special event?
Yes! This cake actually develops deeper flavors after sitting for 24 hours. You can make it a day in advance and store it covered at room temperature, or freeze it for up to 3 months if making further ahead.
Is there a dairy-free alternative for the sour cream?
Plant-based sour cream or full-fat coconut yogurt works wonderfully as a dairy-free substitute, maintaining the moisture and tanginess that makes this cake special.
Why do I need to coat the blueberries in flour?
Coating blueberries in flour helps them remain suspended in the batter during baking rather than sinking to the bottom, ensuring an even distribution of fruit throughout your cake.
