Step-by-Step Instructions
Follow these simple steps to create the most delicious Blueberry Coffee Cake from scratch.
Step 1: Prepare the Streusel Topping
In a medium bowl, whisk together the flour, light brown sugar, granulated sugar, cinnamon, and salt. Add the cold, cubed butter. Using a pastry blender or your fingertips, cut the butter into the mixture until it resembles coarse crumbs with some pea-sized pieces remaining. Place the bowl in the refrigerator to keep it cold while you prepare the cake batter.
Step 2: Preheat and Prep
Preheat your oven to 350°F (175°C). Grease and flour a 9×9 inch square baking pan. This two-step process ensures your cake won’t stick. For another great breakfast dish, check out this easy breakfast casserole.
Step 3: Combine Dry Ingredients
In a separate medium bowl, whisk together the 2 cups of all-purpose flour, baking powder, baking soda, and salt. Set it aside.
Step 4: Cream Butter and Sugar
In the bowl of a stand mixer fitted with the paddle attachment, or in a large bowl with a hand mixer, beat the softened butter and granulated sugar on medium-high speed until light and fluffy, about 3-4 minutes. This step incorporates air into the batter, which is crucial for a light cake.
Step 5: Add Wet Ingredients
Add the eggs one at a time, beating well after each addition. Scrape down the sides of the bowl as needed. Beat in the vanilla extract and sour cream until just combined.
Step 6: Combine Wet and Dry
Reduce the mixer speed to low and add the dry ingredients in two batches, mixing until just combined. Do not overmix; a few streaks of flour are okay. Overmixing can develop the gluten and result in a tough cake.
Step 7: Fold in the Blueberries
In a small bowl, gently toss the blueberries with 1 tablespoon of flour. This light coating helps prevent them from sinking to the bottom of the cake. Gently fold the floured blueberries into the cake batter.
Step 8: Assemble and Bake
Spread the batter evenly into your prepared baking pan. Sprinkle the chilled streusel topping evenly over the batter, covering the entire surface. Bake for 45-55 minutes, or until a wooden skewer inserted into the center comes out with moist crumbs attached, but no wet batter. For a savory baking idea, try these garlic cheese bombs.
Step 9: Cool and Serve
Let the coffee cake cool in the pan on a wire rack for at least 20-30 minutes before slicing and serving. This allows the cake to set properly. Serve warm for the best experience!
Tips for the Perfect Blueberry Coffee Cake
A few expert tips can take your coffee cake from good to great.
- Room Temperature Ingredients: Using room temperature butter, eggs, and sour cream is critical. They emulsify together to create a smooth, uniform batter that traps air, resulting in a fluffy, even bake.
- Don’t Overmix the Batter: Mix the dry ingredients until just combined. Overmixing develops gluten, which can make the cake tough and dense instead of soft and tender.
- Keep the Streusel Cold: Chilling the streusel while you make the batter ensures the butter stays solid. This helps it melt more slowly in the oven, resulting in a crunchier, more distinct crumb topping.
- Check for Doneness Correctly: Ovens vary. Start checking the cake around the 45-minute mark. A tester should come out with moist crumbs, not wet batter. A completely clean skewer might mean the cake is slightly overbaked.
Absolutely. You can bake the entire cake one day in advance and store it covered at room temperature. You can also prepare the streusel topping and the dry ingredient mixture ahead of time to speed up the assembly process on the day of baking.
Yes, you can use frozen blueberries. Do not thaw them before use. Toss them in flour just like you would with fresh berries and fold them into the batter while they’re still frozen to prevent them from bleeding color into the cake.
The best way to prevent blueberries from sinking is to toss them in 1-2 tablespoons of flour before gently folding them into the batter. This light coating helps them grip the batter and stay suspended during baking.
Store the coffee cake in an airtight container at room temperature for up to 3 days. For longer storage, you can refrigerate it for up to a week, though it may be slightly less moist. You can also freeze individual slices wrapped tightly in plastic wrap and foil.
The key to a moist coffee cake is the fat and moisture content in the batter. This recipe uses sour cream, which adds both fat and acidity, resulting in a very tender and moist crumb that stays fresh for days.
