What You’ll Need
Let’s gather our ingredients for this delightful blueberry adventure! You’ll need:
- All-purpose flour: Provides the structure for our cake. (2 ½ cups)
- Granulated sugar: For sweetness and moisture. (1 ½ cups)
- Baking powder: The leavening agent, ensuring a light and fluffy cake. (3 teaspoons)
- Baking soda: Works with the baking powder for optimal rise. (1 teaspoon)
- Salt: Enhances the flavors. (½ teaspoon)
- Unsalted butter: Adds richness and flavor. (1 cup, softened)
- Large eggs: Bind the ingredients and add moisture. (2 large)
- Milk: Adds moisture and tenderness. (1 cup)
- Vanilla extract: For that classic vanilla flavor. (1 teaspoon)
- Fresh blueberries: The star of the show! (2 cups)
- For the streusel topping: ½ cup all-purpose flour, ½ cup brown sugar, ¼ cup rolled oats, ¼ teaspoon ground cinnamon, 6 tablespoons cold unsalted butter (cut into small pieces).
Step-by-Step Instructions
Let’s get baking! Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch baking pan. This ensures easy removal and prevents sticking. You can also line the pan with parchment paper for extra insurance.
In a large bowl, whisk together the flour, granulated sugar, baking powder, baking soda, and salt. Make sure everything is well combined to avoid lumps. Tip: Using a whisk ensures even distribution of the dry ingredients.
In a separate bowl, cream together the softened butter and sugar until light and fluffy. This step is crucial for a tender cake. Use an electric mixer for best results. Creaming the butter and sugar incorporates air, leading to a lighter texture. Beat in the eggs one at a time, followed by the vanilla extract. Mix until well combined.
Gradually add the dry ingredients to the wet ingredients, alternating with the milk, beginning and ending with the dry ingredients. Mix on low speed until just combined. Be careful not to overmix! Overmixing develops gluten, resulting in a tough cake.
Gently fold in the blueberries. Don’t be too rough; you want to preserve their shape. Now, let’s make the streusel topping! In a medium bowl, combine the flour, brown sugar, oats, and cinnamon. Cut in the cold butter using a pastry blender or your fingers until the mixture resembles coarse crumbs. The colder the butter, the better the crumble will hold its shape.
Pour the batter into the prepared pan and sprinkle the streusel topping evenly over the top. Bake for 35-40 minutes, or until a wooden skewer inserted into the center comes out clean. Keep an eye on it during the last 10 minutes of baking; oven temperatures can vary.
Let the cake cool in the pan for 10-15 minutes before serving. Enjoy warm or at room temperature. A slight dusting of powdered sugar is optional, but highly recommended!
Tips for Success
To achieve the perfect moist blueberry coffee cake, follow these helpful tips: Don’t overmix the batter; overmixing leads to a tough cake. Make sure your butter is softened but not melted; melted butter will result in a dense cake. Use fresh, high-quality blueberries for the best flavor and texture. Don’t overload the cake with blueberries; too many blueberries can make the cake sink in the middle. Let the cake cool slightly before slicing and serving to avoid a crumbly mess. And finally, enjoy every delicious bite!
Variations to Try
Feeling adventurous? Let’s explore some exciting variations! Try substituting lemon zest for a citrusy twist. Add a sprinkle of chopped nuts to the streusel topping for added crunch. For a gluten-free version, use a gluten-free all-purpose flour blend. To make it spicier, add a pinch of nutmeg or cinnamon to the batter. A fun variation is swapping blueberries for raspberries or a mix of berries. Let your creativity run wild and discover your perfect blueberry coffee cake combination!
Storing and Reheating
Store leftover cake in an airtight container at room temperature for up to 3 days. For longer storage, wrap tightly in plastic wrap and then foil and freeze for up to 3 months. To reheat, let the cake come to room temperature, then microwave for 15-20 seconds or until warmed through. You can also reheat slices in a preheated oven at 350°F (175°C) for 5-7 minutes, or until heated through. Reheating methods may vary depending on the size of the piece being reheated.

Frequently Asked Questions
