Step‑by‑Step Instructions for Blueberry Coffee Cake
Step 1: Prepare the Streusel
In a medium bowl, combine flour, brown sugar, cinnamon, and cold unsalted butter. Using your fingers or a pastry cutter, mix the ingredients until the mixture resembles coarse crumbs. This streusel will add a delightful crunch to your Blueberry Coffee Cake, so set it aside to firm up while you prepare the batter.
Step 2: Mix Dry Ingredients
In a separate large bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. This blend will ensure your cake rises beautifully. Once combined, set the dry ingredients aside, ready to become part of the luscious batter that will define your ultimate Blueberry Coffee Cake.
Step 3: Cream Butter and Sugars
In a bowl of a stand mixer, beat the softened unsalted butter with both granulated sugar and brown sugar until the mixture is light and fluffy—about 3 to 5 minutes. This step is crucial for incorporating air into the batter, creating a tender cake. The delightful aroma will fill your kitchen, getting you excited for the baking ahead.
Step 4: Incorporate Wet Ingredients
Add the sour cream, eggs, and vanilla extract to your creamed butter and sugars. Mix on medium speed until the mixture is smooth and well combined, which should take about 2 minutes. The sour cream will add moisture and flavor to the cake, ensuring each slice is absolutely irresistible.
Step 5: Combine Mixtures
Gradually add the dry ingredients to the wet mixture, mixing slowly until just combined. Be careful not to overmix; a few streaks of flour are perfectly fine. This gentle approach helps create the perfect texture for your Blueberry Coffee Cake that everyone will love.
Step 6: Add Blueberries
Using a spatula, gently fold in the blueberries, taking care to avoid breaking them apart. The goal is to evenly distribute the juicy bursts of fruit throughout the cake. This step is where the flavor really comes alive, making your Blueberry Coffee Cake a true standout!
Step 7: Bake
Pour the batter into a greased 9×13 inch baking pan and evenly sprinkle the prepared streusel on top. Bake in a preheated oven at 350°F (175°C) for 50 minutes, or until a toothpick inserted into the center comes out clean. As the cake bakes, your kitchen will fill with a mouthwatering aroma that signals a treat is on the way!
Step 8: Make the Glaze
While the cake cools, prepare the cream cheese glaze by whisking together powdered sugar and softened cream cheese in a small bowl until smooth and creamy. Once the cake has cooled completely, drizzle this tangy glaze over the top, creating an eye-catching finish that makes your Blueberry Coffee Cake absolutely irresistible!

Expert Tips for Blueberry Coffee Cake
-
Toss the Blueberries: To prevent blueberries from sinking, dust them lightly with flour before folding them into the batter. It makes a world of difference!
-
Measure Carefully: Use the “spoon and level” technique for measuring flour. This prevents your cake from being too dense, ensuring the perfect texture for your Blueberry Coffee Cake.
-
Avoid Over-mixing: When combining wet and dry ingredients, mix until just combined. Over-mixing can lead to a tough cake; we want it to be tender and moist!
-
Check for Doneness Early: Start checking the cake a few minutes before the suggested baking time. A few moist crumbs on a toothpick mean it’s perfectly baked and not overdone.
-
Store Properly: If you have any leftovers, store your unglazed cake in an airtight container at room temperature, or refrigerate the glazed cake for up to 5 days to maintain its freshness.
How to Store and Freeze Blueberry Coffee Cake
Room Temperature: Store unglazed Blueberry Coffee Cake in an airtight container at room temperature for up to 2 days to retain its moistness.
Fridge: If glazed, keep the cake in the fridge for up to 5 days in an airtight container to maintain freshness and prevent the glaze from melting.
Freezer: For longer storage, wrap the cooled, unglazed cake tightly in plastic wrap and aluminum foil, and freeze for up to 3 months; thaw in the fridge before serving.
