Ingredients You’ll Need

3 cups fresh blueberries: Choose plump, ripe berries for the best flavor. If they’re out of season, frozen blueberries can work, just be sure to thaw and drain them.
3/4 cup unsalted butter, softened: This helps create a moist cake. If you prefer a dairy-free option, you can substitute with coconut oil or a vegan butter alternative.
1 cup granulated white sugar: This sweetens the cake perfectly. Brown sugar can also be used if you want a deeper flavor.
1 cup light brown sugar, packed: Adds a hint of caramel flavor and moisture to the cake.
3 cups all-purpose flour, spooned and leveled: To keep the cake light and fluffy. If you’re going gluten-free, use a 1:1 gluten-free flour blend.
3/4 tsp salt: Enhances the sweetness and balances the flavors.
2 tbsp unsalted butter, softened: Used for the crumb topping to give it a delightful texture.
1/2 cup light brown sugar, packed: This adds sweetness and helps create that crispy topping.
2 tsp cinnamon: This fragrant spice elevates the flavor profile in both the cake and the topping.
1 tsp baking soda: This is the leavening agent that gives the cake its lift.
1 cup buttermilk, at room temperature: Acidity from the buttermilk reacts with the baking soda, making the cake light and tender. You can substitute with regular milk soured with a bit of vinegar if needed.
1 egg, at room temperature: Binds the ingredients together and adds richness.
1 tbsp vanilla: A splash of vanilla enhances the overall flavor.
1 cup powdered sugar: This is used for the glaze that tops the cooled cake, providing a sweet finishing touch.
3-5 tsp whole milk: Adjust the amount to achieve the desired consistency for the glaze.

How to Make Blueberry Coffee Cake

Preheat your oven: Set your oven to 350°F (175°C). This preheating step is crucial for even baking and helps your cake rise beautifully.
Prepare your baking pan: Grease a 9×13 inch pan with a little butter or cooking spray for easy removal later.
Make the crumb topping: In a small bowl, combine 2 tablespoons of softened butter, 1/2 cup light brown sugar, 2 teaspoons of cinnamon, and 1 cup of all-purpose flour until crumbly. Set aside.
Cream the butter and sugars: In a large mixing bowl, beat together 3/4 cup unsalted butter, 1 cup granulated sugar, and 1 cup packed light brown sugar using an electric mixer on medium speed until light and fluffy. This should take about 3-4 minutes—be patient for that perfect texture!
Incorporate the egg and vanilla: Mix in the egg and 1 tablespoon vanilla until well combined, scraping the sides of the bowl as necessary.
Combine dry ingredients: In another bowl, whisk together 3 cups of all-purpose flour, 3/4 teaspoon salt, and 1 teaspoon baking soda. This step ensures the leavening agent is evenly distributed.
Mix the batter: Gradually add the dry ingredients to the creamed mixture, alternating with 1 cup of buttermilk. Start and end with the flour mixture. Mix until just combined—be careful not to overmix; this keeps your cake tender!
Fold in the blueberries: Gently fold in the 3 cups of blueberries, being cautious to avoid crushing them.
Pour batter into the pan: Spread the batter evenly in the prepared baking pan, smoothing the top.
Add crumb topping: Evenly sprinkle the prepared crumb topping over the cake batter.
Bake: Place the pan in the preheated oven and bake for about 50-60 minutes or until a toothpick inserted into the center comes out clean and the edges begin to turn golden brown.
Prepare the glaze: While the cake cools, whisk together 1 cup of powdered sugar and 3-5 teaspoons of whole milk until smooth. Adjust the milk amount to achieve your preferred consistency.
Drizzle glaze: Once the cake is completely cooled, drizzle the glaze over the top for a sweet finishing touch.
Serve and enjoy: Cut into squares and serve warm, or let it cool and enjoy at room temperature!

Storing & Reheating

To store your blueberry coffee cake, keep it in an airtight container at room temperature for up to 2 days. For longer storage, refrigerate it in a sealed container for up to a week. You can also freeze it for up to 3 months. Wrap it securely in plastic wrap, then place it in a freezer bag to prevent freezer burn. To reheat, simply pop it in the microwave for about 20-30 seconds, or bake it in a preheated oven at 350°F for about 10 minutes—this refreshes the texture, making it just as delightful as when you first made it!

Chef’s Helpful Tips

Avoid overmixing the batter after adding the flour; it can lead to a tough texture. Just mix until incorporated!
Make sure your buttermilk and egg are at room temperature for the best consistency.
If you don’t have fresh blueberries, dried or frozen ones work in a pinch. Just adjust the baking time.
Want to add a fun twist? Try folding in some chopped nuts or a sprinkle of lemon zest for bright flavor.

Blueberry coffee cake is both a comforting classic and an easy recipe to share. It’s a delightful choice for breakfast, an afternoon snack, or dessert, and it brings just the right amount of sweetness to any occasion. I encourage you to try it out, perhaps tweak it a bit in your own style, and savor each delicious bite. Enjoy the wonderful aromas as it bakes and the smiles it brings to your friends and family—there’s nothing quite like homemade goodness!

Recipe FAQs

Can I use frozen blueberries instead of fresh?

Absolutely! Frozen blueberries work well in this recipe. Just make sure to thaw them first and drain excess moisture to avoid a soggier cake.

How do I prevent the blueberries from sinking?

To prevent the blueberries from sinking, toss them in a tablespoon of flour before folding them into the batter. This creates a light coating that helps them stay suspended.

Can I make this coffee cake ahead of time?

Yes! This cake keeps well, making it perfect for meal prep. You can bake it a day ahead and store it covered at room temperature or refrigerate it overnight.

What can I substitute for buttermilk?

You can make a quick substitute by mixing 1 cup of regular milk with 1 tablespoon of vinegar or lemon juice. Let it sit for about 5-10 minutes to curdle before using.
