Ingredients You’ll Need

3 cups fresh blueberries: The star of this recipe! Fresh blueberries are preferred for their sweetness and juiciness. Frozen blueberries can work in a pinch; just toss them in flour before adding to prevent sinking.
3/4 cup unsalted butter, softened: Provides rich flavor and moisture. Make sure it’s at room temperature for easy creaming.
1 cup granulated white sugar: Sweetens the cake and balances the tartness of the blueberries.
1 cup light brown sugar, packed: This adds depth and caramel notes to the cake’s flavor.
3 cups all-purpose flour, spooned and leveled: The base of the cake; spoon and level for accurate measurement to prevent a dense texture.
3/4 tsp salt: Enhances all the flavors in the cake.
2 tbsp unsalted butter, softened: For the streusel topping; it should be softened for easy mixing.
1/2 cup light brown sugar, packed: This is mixed into the streusel to add sweetness and richness.
2 tsp cinnamon: Adds warmth and an inviting spice to the topping.
1 tsp baking soda: Helps the cake rise and become fluffy.
1 cup buttermilk, at room temperature: Makes the cake tender and adds a slight tang. If you don’t have buttermilk, feel free to make your own by adding a tablespoon of vinegar to regular milk and letting it sit for 5 minutes.
1 egg, at room temperature: Binds the ingredients together and adds moisture.
1 tbsp vanilla: Pure vanilla extract enhances the cake’s flavor.
1 cup powdered sugar: For a simple glaze that adds sweetness to the top of the cake.
3-5 tsp whole milk: Used to thin the glaze to the desired consistency.

How to Make Blueberry Coffee Cake

Preheat your oven: Start by preheating your oven to 350°F (175°C). This is crucial for ensuring that your cake bakes evenly.
Prepare the baking pan: Grease a 9×13-inch baking pan with a little butter or cooking spray and set aside. This will prevent your cake from sticking.
Mix the dry ingredients: In a large bowl, whisk together 3 cups of all-purpose flour, 3/4 tsp salt, and 1 tsp baking soda. This helps ensure that the leavening agents are evenly distributed.
Cream the butter and sugars: In another mixing bowl, combine 3/4 cup unsalted butter, 1 cup granulated sugar, and 1 cup packed light brown sugar. Beat until the mixture is light and fluffy, which should take about 3-4 minutes.
Add the egg and vanilla: Mix in 1 room temperature egg and 1 tbsp of vanilla extract until fully combined.
Incorporate the buttermilk: Gradually add in 1 cup of room temperature buttermilk, mixing until just combined. It’s important not to overmix at this stage.
Combine wet and dry ingredients: Slowly add the dry ingredients to the wet mixture, stirring gently until a batter forms. You should see streaks of flour but avoid over-mixing.
Fold in blueberries: Gently fold in the 3 cups of fresh blueberries, taking care not to break them up too much.
Prepare the streusel topping: In a separate bowl, mix together 2 tbsp softened butter, 1/2 cup packed light brown sugar, 2 tsp cinnamon, and 1 cup flour until crumbly.
Layer the cake: Pour half of the batter into the prepared baking pan, spreading it evenly. Then sprinkle half of the streusel mixture over the batter. Add the rest of the batter on top and finish with the remaining streusel.
Bake the cake: Bake in the preheated oven for about 40-45 minutes or until a toothpick inserted into the center comes out clean and the edges are golden brown.
Cool and glaze: Once done, let the cake cool in the pan for 10-15 minutes. In the meantime, prepare the glaze by mixing 1 cup powdered sugar with 3-5 tsp whole milk until smooth. Drizzle the glaze over the warm cake before serving.

Storing & Reheating

To keep your blueberry coffee cake fresh, store it at room temperature in an airtight container for up to 3 days. If you’d like to extend its life, refrigerate it for up to a week. For longer storage, freeze it in a well-wrapped container for up to 3 months. When you’re ready to enjoy, simply thaw it at room temperature and warm it in the microwave for about 15-20 seconds, or in a preheated oven at 350°F for about 10 minutes. Keep in mind that the texture may change slightly after freezing, but refreshing it with a quick warm-up works wonders.

Chef’s Helpful Tips

Avoid overmixing: Mixing too vigorously can lead to a tough cake. Stir just until the ingredients are combined.
Butter and eggs at room temperature: Having these ingredients at room temperature ensures they mix well for a lighter texture.
Use a toothpick test: Insert a toothpick into the center to check for doneness; it should come out clean or with a few moist crumbs.
Customize the topping: Feel free to add nuts or oats to the streusel for a different texture and flavor.
Make ahead: You can prepare the batter a day in advance and store it in the fridge, but it’s best baked fresh for optimal texture.

Recipe FAQs

Can I use frozen blueberries instead of fresh?

Absolutely! Frozen blueberries can be used in a pinch. To prevent them from sinking in the batter, toss them in a little flour before folding them in.

How can I make this coffee cake gluten-free?

To make a gluten-free version, simply substitute all-purpose flour with a 1:1 gluten-free baking mix. Make sure to check that the mix contains xanthan gum, or add it separately as needed.

What’s the best way to store leftovers?

For the best results, store the coffee cake in an airtight container at room temperature for up to three days. You can refrigerate it for up to a week but reheating may change the texture slightly.

Can I add more toppings?

Certainly! You can jazz up your blueberry coffee cake with crushed nuts, an additional sprinkle of cinnamon, or even a layer of cream cheese before baking for an extra creamy texture.
